Recycling Outlook for Latin America

Latin America has one of the highest rates of urbanization in the world (80% urban population). By 2050, 90% of Latin America’s population will live in urban areas. This high rate of urbanization coupled with the global economic crisis has resulted in a waste management crisis. Municipalities find themselves unable to keep up with providing services and infrastructure to the urban populations.

recycling-latin-america

Some cities in Latin America are facing this challenge by integrating the informal sector recyclers who are already active in their cities into the municipal solid waste management systems. In many cities, these “recicladores”, “cartoneros” or “catadores” (a few of the many names used for these workers in the region) are responsible for up to 90% of the recyclable waste recovered from the waste stream. Their work reduces municipal waste transportation costs, increases landfill lifetimes and supports the recycling chain throughout the region.

State of the Affairs

Every location presents its own challenges–there is no one-size-fits-all solution for integrated solid waste management systems–but relevant lessons can be drawn from both failed attempts and successful examples of informal sector integration in recycling systems in Latin America.

There are often two very different contexts within cities. In low-income neighborhoods waste collection services are often not provided and individuals and families accumulate and then sell their recyclables for additional income. In contrast, residents in high income neighborhoods do receive a waste collection service and their motivation for recycling is often related to greater levels of environmental awareness. It is important to consider these differences when designing waste management solutions.

Imported systems, and even locally derived systems based on examples from the Global North, generally focus on only one waste management scenario, making it difficult to manage the multiple competing scenarios in many cities in Latin America. There is often a bias towards the automation of waste management services, with the application of the high technology solutions used in the Global North.

Regardless of the practicality or scientific evidence against certain high tech solutions, these are often sought after, thought to raise the bar of the city, to make it appear more sophisticated and modern. This leads to a misconception that working with informal sector is a step backwards in terms of urban development and modernization.

Waste management projects based on public-private partnership (PPP) model has more chances of success in developing countries

Conflicts between private waste management companies, the municipality and informal recyclers are common. The waste management companies do not want pickers on the landfill and wastepickers then go to the municipality for help. However, municipalities usually have very little experience to support the integration of formal and informal waste sectors.

There are opportunities for new systems to emerge within this conflict. For example, during a similar conflict in Mexicali, Mundo Sustentable, with the help of Danone, intervened to help a private company work with the informal waste sector and improve recycling rates.

The Way Forward

In Latin America, there is a great opportunity to increase recycling rates by using labour-intensive solutions, which create jobs and support the development of a better urban environment in the cities. Municipal governments should be an integral part of these processes as they are usually responsible for solid waste management at local level. The key to catalyzing informal recycling sector integration will be the development and dissemination of successful examples.

Informal recyclers provide important a range of services to municipalities (such as waste collection and recovery in communities that would not otherwise have access to them), as well as cost savings (for example, the extension of landfill life and reduced transport costs), yet are rarely compensated for these benefits. Informal recyclers further form the foundation of an entire recycling supply chain, which ultimately benefits formal businesses, and often aliment entire local economies.

Challenges to Overcome

Municipal governments are often hesitant to work with informal actors, who are frequently seen as an unknown quantity. Yet often in the process of working and developing relations with informal recycler groups, their concerns diminish and they may actually exhibit enthusiasm. Likewise, the recyclers may gain in confidence and professionalism in their experience of formalization.

One major challenge facing efforts to integrate the informal sector in developing countries is the desire of some local governments to adopt technological solutions that appear more “modern.” In much of Latin America, however, low-cost, low-tech solutions tend to be more viable and sustainable.

The main difference between Latin America and the countries of the Global North is that solid waste management is a labor intensive system. It is made up of workers and hence has an important social component. The ILO estimated there is 24 million of people working in the global recycling supply chain, but those at the bottom of the pyramid, the wastepickers, make up 80%. They remain the lowest paid even though they make an enormous contribution to their cities.

It is important to understand that highly sophisticated, high technology systems are not required for effective resource recovery. In many cities in Latin America between 80-90% of everything that is recycled is recovered by the informal recycling sector.

Despite the fact that there is little or no public investment in waste management or recycling infrastructure, cities with an active informal sector reach twice the rate of fully formalized municipal solid waste management systems. As an example, the recycling rate is 60% in Cairo, while in Rotterdam (and other cities in the Global North) recycling levels only reach 30%, even with a high public investment in the system (UN Habitat, 2010).

When designing infrastructure and waste management systems we must consider not only the waste management and resource recovery needs but also the social side of the system. In order to be effective, efforts to upgrade waste management services should go hand in hand with efforts to formalise and integrate the informal sector.

Bogota – A Success Story

An example of a recent success story is that after 27 years of struggle, the waste pickers in Bogota, Colombia have managed to change the government’s outlook on their work and their existence. They are now included in the system and are paid per tonne of waste collected, just like any other private sector collection and waste management company would be. They have become recognized as public service providers, acknowledged for their contribution to the environment and public health of the city.

The key challenge is to be much more creative and understand that in order to improve the working conditions of waste pickers and in order to increase recycling rates, we don’t need high technology. We need a systemic approach and this can be very simple sometimes infrastructure as simple as a roof [on a sorting area] can be effective in improving working conditions.

6 Ways on How Homeowners Can Create an Oasis in Their Backyard

It is of vital importance that we unwind now and again, especially after a hard day at work. Spending hours staring at a computer screen, or doing physical work can take its toll on both the mind and the body. However, jetting off to a remote beach isn’t always an option. Since the pandemic began in early 2020, travel restrictions have been put in place. Although a lot of these restrictions have been lifted, people are still opting to spend more time at home.

You might not have known how lucky you were to have a backyard on your property prior to the pandemic. However, when the coronavirus started spreading across the globe and governments started to enforce lockdowns to help reduce the spread of the virus, homeowners were able to enjoy the great outdoors without having to put others at risk by relaxing in their backyards. These unprecedented times have motivated a lot of people to invest in their yard to make it even more appealing. Some find it the best area to relax, and by making transformations to your yard, you can create a tranquil environment where you can switch off from the rest of the world. Here’s how to turn your backyard into an oasis:

How Homeowners can Create an Oasis In their Backyard

1. Swimming Pool

You don’t need to install an Olympic sized swimming pool at home, but a small sized outdoor pool can completely transform your property. Most swimming pool companies offer a range of different pools, so you are bound to find one that suits your yard. There is nothing better than diving into your own pool at home during a hot day. Kids can spend hours splashing around without getting bored. It will encourage your friends and family members to pop over for a visit (which might be a good or bad thing!) more often. You can spend your afternoons relaxing in the pool, but swimming is also a great exercise.

However, purchasing a pool can cost a pretty penny, and the maintenance cost can add up too. You will need lots of cleaning equipment and chemicals to keep it spotless. If there are small children in your family, make sure that you install a sturdy fence around the pool so kids are unable to gain access to it.

2. Install a Deck

If you have a lot of free time on your hands, you might be interested in designing and building a deck in your yard. A deck is a great place for families and friends to enjoy a meal and socialize with one another. Kids can enjoy playing in the yard while their parents can keep an eye on them while relaxing on the deck. Some people hold birthday celebrations and other events on their deck, especially during a nice day.

A deck creates another space for people to hang out, which is ideal if you are expecting a lot of visitors. You can set up a BBQ on the deck, along with tables and chairs. Families can enjoy eating outside on the deck on a regular basis.

ways to increase the value of your home

Installing a deck without experience can prove challenging, especially if you don’t have the proper tools on hand. You will want to make sure your deck is completely safe so nobody sustains an injury while on it. It might be a good investment to hire a reputable company like McNish deck builders Orlando to build and install your deck.

If you wanted to go all out, you could consider installing an outdoor kitchen on your deck. Outdoor kitchens are becoming extremely popular nowadays, and if you love to cook, then it might prove to be a superb investment.

3. Plant Flowers

Unlike installing a pool or a deck, planting flowers is easy, so you don’t need to spend money on hiring a professional to do it for you. You don’t have to be an expert to plant and enjoy flowers, and you can even get the kids to give you a helping hand. They will add color to your landscape and brighten up your property. When the flowers are in bloom, you can take cuttings and give them away as a gift or put them in a vase in your home.

Gardening itself can be a lot of fun, and it can help reduce feelings of stress. It’s an inexpensive hobby people of all ages can enjoy. Flowers can help add curb appeal to your home, so if you are planning on selling down the line, you can expect potential buyers to take notice. Consider hanging plants in different areas around your yard as this can help add to the ambiance of your home.

4. Declutter

Adding new things to your backyard is one thing, but sometimes taking away a few items is the best way of creating a backyard oasis. If there are lots of objects lying around your yard, it is going to be hard to feel relaxed. It might be time to dump some of the items in your yard or move them to a different area if you want to create a peaceful environment. Get rid of things that aren’t any use to you, even if they have been in the same position for several years.

For example, if there are children’s swings in your yard but the kids don’t seem to use them anymore, perhaps it’s time to give them away or put them up for sale. You can then utilize this free space for something else. Damaged furniture can be an eyesore, so either refurbish them or replace them with new comfortable tables and chairs.

5. Invest in Solar Powered Outdoor Lighting

Solar powered outdoor lighting to help enhance the mood of your backyard. You won’t need any electrical wires connecting to the mains in the house if you invest in solar powered lights, and you should have no issues installing these lights into the ground. You can create a pathway around your yard with lights, or even use them for security purposes. Some even have a dimmer feature so you can alter the brightness of the lights depending on the type of atmosphere you are hoping to create.

solar-powered-lights

Solar powered lighting won’t increase your utility bills and they are extremely easy to maintain. Most online marketplaces stock a variety of solar powered devices, so you should easily find nice lights for your home. A compact 200W solar panel is more than enough to handle your lighting needs.

6. Build a Fire Pit

Another area where people like to socialize with one another is by a fire pit. A fire pit or an outdoor fireplace could be exactly what your yard needs to transform it from a basic yard to an oasis. Building a fire pit is easy, and there are several DIY stores selling all the equipment you will need to create this beautiful feature. Having a fire in your yard can provide people with heat and comfort. Even when the temperatures drop, your guests and family members might want to stay outside by the fire.

If you do install a firepit, make sure that young children are aware of the dangers that a fire can cause. Consider having fire safety equipment, like a fire blanket and an extinguisher close by in case an accident occurs. Before calling it a night, make sure that you put the fire out.

5 Reasons to Choose Rail Travel

Are you debating the best way to get from A to B? Are you considering travelling by rail – but not sure if it offers the most benefits? You’re in the right place. Here, we explore five reasons to choose rail travel.

1. You can be productive

If you’re driving a car, you need to place your undivided attention on the road in front of you. When you take the train, however, you’re free to spend your time onboard as you wish. Whether that’s being productive by getting some work done on your laptop, relaxing with your favourite podcast or refuelling with a bite to eat, you can make the most of your time spent travelling.

2. It’s better for the environment

Studies have shown that public transport can help to tackle climate change – by reducing the reliance on individual car journeys and therefore lowering overall emissions from petrol and diesel. In the US, greenhouse gas emissions caused by transport accounts for around 29% of the country’s total emissions – so by having less cars on the road, emissions can be reduced. This will in turn improve air quality, particularly in urban areas, leading to a healthier population.

3. You can avoid traffic

Have you ever been in a rush to get somewhere, got stuck in a traffic jam and ended up being late? You’re not alone – many of us have been caught out by heavy traffic at one time or another. Travelling by train means you don’t need to worry about getting stuck in traffic, you can simply hop onboard and get from A to B with ease. For instance, if you need to travel by train from Cambridge to Hatfield in rush hour, you’ll typically arrive in less than an hour with no stress about traffic or parking.

4. It’s fast and efficient

Another benefit of travelling by rail is that it’s fast and efficient. Many rail services can travel at impressive high speeds which are much quicker than that of a car on the road. Of course, how fast the train travels will depend on the service and model – but some of the fastest trains in the world include the Shanghai Maglev at 267mph and the Fuxing Hao at 249 mph.

5. It’s cost-effective

Travelling by train may also be a more cost-effective option than travelling by car or plane. This really depends on where you’re travelling to and from, so it’s important to do your research before you book your travel. In some cases, you may be able to take advantage of deals and discounts from the train provider. For instance, you can often get great value fares if you have a railcard or travel at Off-Peak times.

Will you take the train next time you have to travel?

7 Myths About Smart Homes

A Smart Home has been on everyone’s lips in recent years. However, some issues remain relevant years later. In the article we will analyze the main misconceptions about a Smart Home, adding examples and explanations.

Myth 1 – The use of smart technologies will lead to an increase in the number of wires, which are already difficult to understand

It is precisely because of the use of an aging mechanical control system that an incredible number of wires appear.

Modern Smart Home systems assume only one wire to each light source. And there is no need to start repairs if you want to add a new option. All this is done at the programming level and saves you money and nerves. And the introduction of a new light source will require an additional laying of just one wire.

Myths about Smart Homes

Myth 2 – The Smart Home system is difficult to understand

Modern housing involves numerous groups of light. In front of us are many mechanical switches that are trying to control all this. Is it easy to remember which button is responsible for what?

In Smart Home, the push-button control panels have a built-in indication for displaying feedback. To simplify the control on the panel with mechanical keys, the manufacturer can engrave, which will make the control process even more intuitive.

Myth 3 – Using such a large amount of electronics will inevitably lead to higher energy bills

Everything is exactly the opposite. Smart Home technologies use low-current controllers, and their availability will optimize the use of electricity in the room. For example, the light will automatically turn off in a room where there are no people, and all equipment will be in sleep mode. You can also adjust the lighting so that it does not shine at full power during daylight hours. Such optimization can be carried out not only with light but also with heating.

Myth 4 – The Smart Home is a technology for the construction stage, and it is difficult to install it on existing buildings, if possible

Along with the rapid development of the world, the requirements for comfort and the level of housing are also developing. Many manufacturers are still at the development stage considering the possibility of integrating their devices into a Smart Home system.

There is a smooth transition of the old energy supply system to a new highly intelligent one. This will require the least of costs for repairing the premises, but it guarantees increased control over engineering systems, significant resource savings, and, most importantly, a level of comfort that is inaccessible to the classical system.

Myth 5 – Building a Smart Home or rebuilding an old one entails a lot of legal problems

The myth of the difficulties of legal support for the construction of Smart Homes and the rebuilding of ordinary houses into smart ones was invented by those who did it on their own. Lawyers in Dubai will help you save time on legal registration.

Myth 6 – The Smart Home is very sensitive to power loss

This is a problem of Smart technologies. But now the devices are equipped with non-volatile memory. In practice, this means that when power is lost, the modules fall asleep, completely without losing settings and certainly without breaking.

smart homes

Myth 7 – Smart Home technology is just an advanced toy that will quickly get bored

Smart Home technologies will work properly and bring benefits regardless of the lively interest in them. The fact that the user gets used to them so easily and no longer sees something incomprehensible in them speaks in favor of the fact that such technologies will soon become commonplace and standard.

Designing a Smart Home is much easier than a classic one. There is no need to worry about each transaction, remember its functionality and the specifics of what it leads to. A Smart Home will allow you to arbitrarily set the functionality of each device without using additional communications.

The Smart Home is the choice of those for whom the house is not only a fortress but also a place of comfort when the house almost guesses the wishes of its owner. You will forever forget the irritated voice: “Turn off the light after you!

Wonderful Tips to Avoid Heat Loss from Your Home

Heat loss is a big problem to homeowners. It comes with various issues including a skyrocketing energy bill. Most of the heat is lost through the windows and doors. Luckily, there are some ideas that can help you improve insulation and lessen loss of heat. When choosing fixtures, timber doors and windows are a wonderful option for their amazing insulating properties. Additionally, here are 5 tips to avoid heat loss from your home.

Install curtains

Thick close fitting curtains and blinds will keep warm air inside your home. The curtains and blinds hit the colder window class and cools it down plus lessening draught. Consider installing a pelmet above your curtain rail to enhance thermal insulation more.

Blinds offer tremendous versatility and boost insulation in your home. These leave a smaller gap between slats where less heat escapes from. you can open the curtain and blinds to let the sun enter and close them in the night to lessen heat loss. Installing curtains is a wonderful idea to enhance the security of your home. These windows have hook shaped locks embedded in the window frame leaving them untouchable.

Choose an appropriate glass type

There are various kinds of glass offering different thermal efficiency. Luckily, modern double glazed windows have low emissivity coating. This means they can reflect heat back into your home. Therefore, they are a wonderful option because they offer better thermal insulation compared to plain glass with no coating.

Opt for double glazed windows

You should consider double glazed timber windows and doors in Melbourne to prevent heat loss. Single glazed options lose about 20 percent of the heat in your home. double glazed options have a gap between the panes of glass full of gas such as argon, xenon, and krypton, which is a poor conductor of heat. This helps to lessen chances of heat loss. A reliable company should offer slimmer glazing units for a contemporary and elegant appeal.

Use warm edge spacer bars

A perimeter spacer bar sits between 2 panes of glass holding them apart in double glazing. Spacer bars have desiccant for absorbing moisture that might be in the unit. It is made of aluminium for its high conductivity and ability to lose heat fast.

Warm space bars made of pre desiccated structural foam help enhance the temperature in the internal edge of glass by up to 65 percent. This is better than the use of aluminium spacers. Additionally, warm spacer bars reduce noise by about 10 percent to keep your home quieter and warmer.

Consider draught proofing

These windows allow the breeze to move at acute angles along your house. Therefore, with curtains windows, you will catch side breezes inside your house.It is a wonderful idea to consider modern windows and door but you have to realise that there is a chance of your home getting draughty with time. Consider installing draught proofing to enjoy more energy efficiency, sound proofing, and no chance of draught in your interior.

Mind your style

Choosing the right colour for curtains windows is a personal decision. Therefore, always ensure to choose a colour that effortlessly reflects your style. Luckily, wooden windows offer a wide range of colour options. It is very important to consider the design you are seeking to achieve. Crisp white is a wonderful option if you want a simple but timeless appeal on your home

Final thought

There are various consideration when choosing the best windows for your home. Keeping your home well insulated is a wonderful option. It comes with a variety of benefits including enhancing the appeal of your home, lowering energy bills, increasing comfort in your interior, and making your home more attractive to prospective buyers. A wonderful trick is to opt for double glazed timber windows that help lessen heat loss.

How Using Energy-Efficient Technologies Can Contribute to Sustainability

Economies use energy to help them grow. It is needed in many sectors such as manufacturing and mining, public infrastructure, agriculture, and others. Although energy is important in these sectors, economies are realizing the importance of using sustainable energies. They have seen some undesirable results that come with using unsustainable energy and they seek to reduce them.

Energy-efficient technologies are important to consider at an organizational level for any organization seeking to be environmentally conscious. These technologies are using alternative sources of energy such as wind, solar, hydroelectric, biomass, geothermal, which are cleaner and sustainable. Let us see how these energy-efficient technologies can contribute to sustainability:

How Energy-Efficient Technologies Can Contribute to Sustainability

1. Reduce Greenhouse Gas Emissions

Coal, distillate fuel, and natural gas produce carbon dioxide, which is a greenhouse gas. The aim of using sustainable technologies is to reduce the emission of these gases.

With alternative sources of energy, the emission of these gases is reduced. Unlike coal and natural gas, these alternatives do not produce carbon dioxide that can increase the amount of greenhouse gases during combustion. Biomass, for example, has its carbon dioxide neutralized by plants during the natural carbon cycle. So, any carbon dioxide produced during the combustion of biomass is considered neutral.

Interestingly, biomass produces the same amount of carbon dioxide in the atmosphere during decay, which is also a natural cycle.

Fossil fuels, on the other hand, have their carbon dioxide locked for as long as they exist. When not combusted, these fuels do not emit this gas to the atmosphere. Instead, it keeps building up, and when combusted, all the gas is released.

So, instead of using fuel whose carbon dioxide has been building up for years, using alternative sources such as biomass, solar and wind are more sustainable because they do not increase the level of greenhouse gases.

2. Prevents the Depletion of Natural Resources

Fossil fuels occur naturally and are non-renewable. When solely dependent on energy, these resources continue depleting because as the global population increase, the need for more production increases.

Alternative sources of energy such as wind, solar, and geothermal are sustainable options. These sources are renewable and can never be depleted. They are also clean sources of energy. When used, they help in preventing the destruction of natural habitats, reducing global warming, and climate change.

When economies embrace the use of sustainable technologies, there will be reduced demand for energy from natural resources.

3. Help Companies Save on Energy Bills

Companies often spend a lot on their energy bills. But, they can reduce them and have a lower cost of production. It means they can sell their products with better profit margins by either reducing their prices and increasing their demands or selling at the same price. On average, they reduce their energy bills by 75% when they use energy-efficient technologies.

reduce electricity bill

To enjoy energy-saving, a company can invest in wind or solar energy. Wind turbines are used for converting wind into energy while solar panels are used for converting solar into energy. Depending on a company’s need for power, the installation capacity varies.

4. Create Better Living Standards

Emerging and developing economies have a high energy demand. These economies largely depend on non-renewable sources of energy such as coal, natural gas, and oil. These fuels are carbon-emitting and can create health implications.

With energy-efficient technologies, these economies can have access to clean energy. It is environmentally friendly, which means they will have less pollution in the air.

Besides, these sources of energy are easy to obtain because they occur naturally and are renewable. They are also cheaper when compared to non-renewable sources, which makes them affordable. When people from these economies use such energy, they have better living standards in terms of health and affordable living.

5. Reduce Soil Degradation

Soil degradation is a major problem facing farmers around the world. It has been estimated that globally, approximately 40% of agricultural land is degraded. The main causes of soil degradation are poor farming practices, climate change, and human activities such as deforestation, urbanization, and industrial development.

There are several ways to address soil degradation, including improving crop rotation, using cover crops, and applying organic amendments. However, these methods are often expensive and require significant investment.

A new technology called energy-efficient technologies (EETs) could provide an affordable solution to soil degradation. EETs, use solar power to generate electricity, which can then be used to run farm equipment.

6. Job Creation

Economies are using energy-efficient technologies such as wind and solar power to produce power. They have been transitioning from using non-renewable fossil fuels in a bid to reduce production costs and maximize their profits.

energy efficient technologies

The transition from fossil fuel to using clean energy has helped with job creation in many countries around the world. For example, a study by the international renewable energies agency found that every $1 billion invested in renewables creates about 2 million new jobs worldwide. This is because of the increased demand for workers who install, maintain, repair, operate, or sell these systems. So, people are able to earn a livelihood, which improves their standards of living.

Because there is an increasing rise in demand for energy-efficient technologies, there will be a continuous demand for labor. Skilled, semi-skilled, and unskilled labor will be wanted during the transition. It means many people, regardless of their qualifications will have somewhere to earn a living.

7. Sustainable Economic Development

Sustainable economic development aims at reducing the consumption of fossil fuels and reducing emissions from waste generation.

The following is a list of some examples:

Energy efficiency in buildings can be achieved by using more insulation materials or better windows to keep heat inside during winter time and cool air outside during summertime. This will save on heating costs for people living there. It also reduces carbon dioxide emission which contributes to global warming.

In the transportation sector, electric vehicles have been developed as an alternative to conventional gasoline-powered cars. These use clean energy that does not interfere with the atmosphere.

Using energy-efficient technologies has many benefits towards creating sustainability and economies should embrace them.

3 Tips to Help Keep Your Sewer Line Cleared

A sewer back up can be one of the costliest, messiest and most stressful problems you will ever have to deal with. It is possible that raw sewage can back up into your toilet, sink and bathtub, eventually overflowing into key areas of your house. It’s admittedly a disgusting topic to talk about, but it does happen, and it is important to know how to prevent it. So, here are a few tips on how to clear a mainline blockage:

1. Clear Roots

These are the most common culprits behind sewer backups. Roots belonging to trees and shrubs seek moisture underground and can, therefore, make their way into sewer lines through cracks in the pipe. Typically, they start small but grow and eventually obstruct the line, allowing waste to build up and back up. Here are some tips on using salt to get rid of such tree roots.

  • Obtain 4 pounds of rock salt and flush it down the toilet in the evening before the family goes to bed. That will give the saltwater at least 8 hours in the sewer line. For that duration, do not use any drains in the house to avoid diluting the saltwater.
  • After 8 hours, flush the toilet again and resume use of the drains in the house.
  • Follow this practice about once or twice a month. Any tree roots in the sewer line will die from the excess of sodium, and the lines will soon be clear.

2. Clear Paper Products

These include such products as paper towels, sanitary towels and diapers that are not intended for flushing. These products aren’t like toilet paper in that they do not disintegrate easily. They can, therefore, block the sewer line and cause a backup. To prevent this from happening, they should not be flushed down the toilet but should instead be thrown in the garbage.

Sanitary towels and diapers should never be flushed down the toilet as they tend to clog the sewer line the fastest. This also includes tampons. All of these should be disposed of in a specialized garbage bin placed next to the toilet, such as the ones in public restrooms.

3. Avoid Putting Grease in Drains

Grease is another culprit that has a way of causing backups. You should avoid, as much as possible, pouring grease down a drain. This also applies to cooking oil as it often has the same effect. Some people believe that using hot water to wash grease down the drain helps. That is not true. The grease will go down the drain more easily, but it will eventually cool off further down the drain and solidify. When it does that, it will clog the drain and cause a backup.  The line will have a harder time letting water through and get clogged.

The best solution is to pour the grease into a container that is resistant to heat and let it cool off. You can then dispose of it in the garbage.

Your Ultimate Guide to Going Solar

Many homeowners decide to switch to solar energy, and it should come as no surprise. These days, according to the 10 PowerUp buyer’s guides, you can get your hands on a wide range of solar-powered products, which makes going solar a breeze.

However, you might end up feeling kind of confused about it. How does it work? Is installing solar panels on the roof of your house a viable option? If you want to know the answers to such questions, keep reading!

In this article, you will find a guide to going solar. It will touch upon a number of important points, including how solar power works and how much it costs, as well as what the benefits and drawbacks of going solar are. Check it out!

solar-battery

 

How Does Solar Power Work?

Solar energy is produced by photovoltaic cells, which are thin sheets of silicon that are coated in layers of certain chemicals and meant to capture sunlight. Solar panels are made of numerous photovoltaic cells and mounted on the roof of a house.

The amount of energy that a typical house can produce that way depends on where it is located, but it can range from 1 kW to 4 kW per day, making solar energy an attractive choice for environmentally conscious individuals.

How Much Does Going Solar Cost?

The cost of installing solar panels has decreased dramatically in the past couple of years. These days, solar panels cost $0.70 to $1.50 per watt. It used to be around $2.10 and more just a few years ago. This reduction in price has made solar power incredibly affordable!

Unfortunately, the initial cost of installing solar panels on the roof of a house can range from $15,000 to $20,000. However, it is definitely worth it, as you will get to save money on your utility bills, as well as increase the price of your house.

How Is Solar Energy Better Than Fossil Fuels?

Solar energy is completely renewable, while fossil fuels are finite and are bound to be depleted. In addition to that, fossil fuels cause greenhouse gas to be emitted into the atmosphere upon being burned, which contributes to global warming. On the other hand, solar energy does not emit greenhouse gases, which makes it incredibly environmentally friendly.

Why Should You Go Solar?

There are quite a few reasons why you might want to switch to solar energy. First, it will help you conserve resources and protect the environment. Second, it will reduce your reliance on fossil fuels. Lastly, it will help you lower your utility bills.

What Are the Benefits of Going Solar?

1. Cost Savings

One of the biggest benefits of solar energy is that it can help you lower your utility bills. It might be a pricey investment, but it will definitely pay off in the long run, particularly if you live in a sunny area.

minnesota-solar

2. Environmental Protection

Going solar can help you protect the environment! It will effectively reduce your carbon footprint, allowing you to become less reliant on fossil fuels. It is a great option for people who are environmentally conscious!

What Are the Drawbacks of Going Solar?

Requirements

In order to be able to benefit from solar panels, you need to own a house that is located in a sunny area and gets a minimum of four hours of direct sunlight per day. Moreover, your roof needs to be able to withstand the weight of the panels.

How Do I Get Started?

The first step that you will need to take to go solar is to determine if installing solar panels on your house is a viable option. If your house does not get direct sunlight and has a roof that is unable to withstand the weight of the panels, going solar might not be possible.

If you know for a fact that solar panels can be installed on your house, you can start reading up on the installation process. You can go about installing solar panels in a few different ways, but the most common one is hiring a professional solar panel installer to take care of it for you.

Other than that, you will need to check if your solar panels are working properly. If you decide to purchase a more modern set of solar panels, you should be able to do it using a special mobile application.

Once you have checked if your solar panels are working properly, you can start harnessing the power of the sun! However, you might want to keep on monitoring your solar panels just to be certain that everything is working the way it should be.

The Bottom Line

To sum up, solar power is a smart investment that can save you money on energy bills. However, you will need to put in a lot of effort in order for it to pay off. For starters, you will need to educate yourself on the basics of solar energy and install the panels correctly. That being said, it is definitely worth the hassle, as it will allow you to lower your carbon footprint and do your part in protecting the environment!

The Concept of Passive House: An Interview with Toyin-Ann Yerifor

Green building concepts have come a long way. As architects, designers, and builders gain access to better tools that help push the limits of construction energy efficiency; we see longer strides made towards more mainstream adoption of green building standards. One such standard that is coming of age is passive houses. The concept of passive houses was first mooted in the early eighties when the idea of green homes was still in its infancy. Today, the concept is well entrenched with over 25,000 houses and buildings across the world qualifying as passive houses.

We recently caught up with Toyin-Ann Yerifor, an architectural consultant focused on exploring new and innovative ways to design with reduced impact on the environment to explain what passive houses are and their benefits. She holds an MSc in Architecture (AEES) from the University of East London, an MBA from the University of Northampton and an MSc in Computer Science and Engineering from the Université Grenoble Alpes.

What is a Passive House?

First, what is a passive house? Toyin-Ann explains: A passive house is any building that adheres to rigorous energy efficiency standards. The term passive comes from the fact that the building’s energy efficiency comes from its passive structures, which include the roof, walls, windows, doors, and floor. By radically improving the building’s insulation and energy conservation features, it is possible to reduce its heating requirements by up to ninety percent. As such, passive housing as a standard is focused on helping reduce the energy requirements of buildings through insulation, and by extension, their overall energy footprint.

When you reduce a building’s energy footprint, says Toyin-Ann, several benefits accrue, including environmental, health, and cost efficiency benefits.

Environmental Benefits of Passive Houses

According to the International Energy Agency (IEA), “energy efficiency is the first fuel of a sustainable global energy system. It can mitigate climate change, improve energy security, and grow economies while delivering environmental and social benefits.” Passive houses deliver on this mandate superbly, says Toyin-Ann Yerifor.

One of the biggest challenges traditional buildings face is energy loss. When a building easily loses energy in the form of heat, it takes burning more fuel to heat the building. When this happens, overall energy consumption goes up, which is bad for the environment because a major portion of heat generation comes from burning fossil fuels. When buildings are radically energy efficient, on the other hand, less energy is required, and so fewer fossil fuels need to be burned.

While this is the macro view of the environmental benefits of passive houses, are there any micro benefits of investing in this technology? Here are two, says Toyin-Ann Yerifor. First, think of the air quality that comes with less energy consumption. In homes that rely on furnaces, doing away with the furnace improves the air quality in and around the home significantly.

Second, sound pollution is eliminated if you no longer need to use a furnace, HVAC units around the home, or any other heat generation and management devices. Essentially, says Toyin-Ann Yerifor, passive houses reduce the need to burden the environment. Through radical energy efficiency and self-sufficiency, passive house buildings become a part of the environment and not just an addition to it.

Health and Comfort Benefits

When most people hear about passive houses, they imagine living in a sealed paper bag. That thought can be quite disheartening because issues of quality of air, air adequacy, and comfort come to mind. Although the idea behind passive houses is energy efficiency through a tightly sealed envelope (building), this does not mean health and comfort are compromised. Take air quality, for instance. Most people consider opening a window the best way to guarantee air quality in a room. Now, passive houses rely on closed windows to ensure no heat escapes, which presents a dilemma. Passive houses address this dilemma well, says Toyin-Ann Yerifor.

Although you can open a window in a passive house, even if you do not, the heat recovery ventilation system ensures there is enough quality air circulating the house. Regarding comfort, passive houses maintain a comfortable temperature regulated by the passive heat sources in the house like appliances, body heat, and lighting. Also, they tend not to have cold spots or hot spots, which is often the case with traditionally heated homes. Through rigorous design standards afforded by tools such as the Passive House Planning Package, homes built on the passive house standard adhere to comfort standards as rigorous as the energy efficiency standards stipulated.

Cost Efficiency Benefits

Cost efficiency is at the heart of the passive house concept. When a building is exceptionally well insulated, it can use as little as 10 percent of its regular heating energy requirements. This, of course, also significantly reduces the costs associated with heating the building. So, how does the passive house concept achieve such a radical reduction in energy needs? The answer is insulation, says Toyin-Ann Yerifor. Passive houses rely on extensive insulation to gain this level of energy efficiency. Why is insulation so effective?

Traditional buildings lose a lot of heat through the roof, walls, floor, doors, and, most of all, windows. With a passive house, each of these structures is carefully designed and built to ensure close to zero loss of heat. When you look at the thermal scan of a passive house next to a traditional house, you’ll notice the passive house is almost entirely blue, meaning there’s close to no energy loss. The other building is close to all red, meaning it is losing a lot of energy. This level of energy conservation and efficiency is what leads to the massive energy savings that make passive houses so cost-efficient.

Passive houses are a concept that is yet to hit mainstream construction. However, this does not mean it is impractical to build passive houses. What it does point to is the need for better awareness of the concept. Toyin-Ann Yerifor recommends anyone interested in the concept to visit a passive house showcase home to experience its benefits firsthand. She says this is the only way to understand and internalize this breakthrough energy efficiency concept.

Rice Straw As Bioenergy Resource

The cultivation of rice results in two types of biomass residues – straw and husk – having attractive potential in terms of energy. Rice husk, the main by-product from rice milling, accounts for roughly 22% of paddy weight, while rice straw to paddy ratio ranges from 1.0 to 4.3. Although the technology for rice husk utilization is well-established worldwide, rice straw is sparingly used as a source of renewable energy. One of the main reasons for the preferred use of husk is its easy procurement. In case of rice straw, however, its collection is difficult and its availability is limited to harvest time.

Rice straw can either be used alone or mixed with other biomass materials in direct combustion, whereby combustion boilers are used in combination with steam turbines to produce electricity and heat. The energy content of rice straw is around 14 MJ per kg at 10 percent moisture content.  The by-products are fly ash and bottom ash, which have an economic value and could be used in cement and/or brick manufacturing, construction of roads and embankments, etc.

Straw fuels have proved to be extremely difficult to burn in most combustion furnaces, especially those designed for power generation. The primary issue concerning the use of rice straw and other herbaceous biomass for power generation is fouling, slagging, and corrosion of the boiler due to alkaline and chlorine components in the ash. Europe, and in particular, Denmark, currently has the greatest experience with straw-fired power and CHP plants.

Because of the large amount of cereal grains (wheat and oats) grown in Denmark, the surplus straw plays a large role in the country’s renewable energy strategy. Technology developed includes combustion furnaces, boilers, and superheat concepts purportedly capable of operating with high alkali fuels and having handling systems which minimize fuel preparation.

A variety of methods are employed by the European plants to prepare straw for combustion. Most use automated truck unloading bridge cranes that clamp up to 12 bales at a time and stack them 4-5 bales high in covered storage. Some systems feed whole bales into the boiler. Probably the best known whole bale feeder is the “Vølund cigar feeding” concept, originally applied by Vølund (now Babcock and Wilcox-Vølund). Whole bales are pushed into the combustion chamber and the straw burned off the face of the bale.

However, the newer Danish plants have moved away from whole-bale systems to shredded straw feed for higher efficiency. For pulverized coal co-firing, the straw usually needs to be ground or cut to small sizes in order to burn completely within relatively short residence times (suspension fired systems) or to feed and mix upon injection with bed media in fluidized bed systems.

The chemical composition of feedstock has a major influence on the efficiency of biomass cogeneration. The low feedstock quality of rice straw is primarily determined by high ash content (10–17%) as compared with wheat straw (around 3%) and also high silica content in ash. On the other hand, rice straw as feedstock has the advantage of having a relatively low total alkali content, whereas wheat straw can typically have more than 25% alkali content in ash.

However, straw quality varies substantially within seasons as well as within regions. If straw is exposed to precipitation in the field, alkali and alkaline compounds are leached, improving the feedstock quality. In turn, moisture content should be less than 10% for combustion technology.

In straw combustion at high temperatures, potassium is transformed and combines with other alkali earth materials such as calcium. This in turn reacts with silicates, leading to the formation of tightly sintered structures on the grates and at the furnace wall. Alkali earths are also important in the formation of slag and deposits. This means that fuels with lower alkali content are less problematic when fired in a boiler.
