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.
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 building 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.
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.
You’ve probably heard the word “sustainable” many times by now, but you may wonder what it has to do with your business. Sustainable business means that you’ll be you’ll be increasing the odds that you company can continue indefinitely by minimizing social and environmental impacts while ensuring financial stability. Studies have shown that sustainable business perform better financially, including one report by nonprofit CDC, reported by The Guardian that found they secure an 18% greater return on investment (ROI) than organizations that aren’t, and 67% more than companies who refuse to. How can you help your business become more sustainable?
Think Greener in Procurement Sources
One of the best, and easiest, things you can do to make your business more sustainable is to practice environmentally-friendly procurement. Take a close look at your current suppliers and make changes as necessary by using suppliers that don’t use excessive packaging or sell products that contain substances that are harmful to the environment.
Whenever possible, use local suppliers, rather than purchasing online.
Seek Help from an Energy Broker
An increasing number of businesses are embracing renewable energy and energy management today. Your office can be powered with a variety of alternative sources like biomass, hydropower, geothermal, solar and wind power. There are hundreds of companies that supply energy in a myriad of different ways, affecting your bottom line and sustainability.
While there are usually a few suppliers dominating any given market, many other small suppliers are known for getting more creative in their offerings. Trying to figure out which one is best for your organization can be a very difficult task which is why using an energy broker who is knowledgeable about all the complexities that come with this sector, can best analyze the energy market to provide you with the greenest, most cost-effective options.
Reduce Water Usage
Water shortages are becoming an increasingly bigger problem in many places around the world, including North America. Whether your organization is located in a drought-stricken area or not, decreasing water use will help to conserve a valuable resource and help you save money at the same time.
Instead of using a sprinkler system to keep lush lawns around the building, switch to a drip irrigation system to significantly reduce water usage or consider changing the landscaping to something more drought tolerant. Fix plumbing leaks and dripping taps and install low-flow faucet aerators in your bathrooms.
Switch From Gas To Electricity
Electricity is much easier to source sustainably than gas and oil, especially if you use solar panels to collect energy from the sun. So by switching over some of your gas-powered company owned equipment to their electric counterparts you can ultimately help your business become more sustainable.
Some equipment to consider switching could include: switching from gas powered to electric vehicles (especially for companies that rely heavily on transportation), switching from gas-powered to electric-powered riding mowers (especially for landscaping businesses).
As there are so many different types of lawn mowers available, sites like home gear expert show us interesting comparisons which will help you find the one which best matches your needs.
A good electric riding mower with good user ratings will cost you a couple thousand dollars but could save you money in the long term plus make your business more sustainable.
Cities often compete with each other, whether they’re seeking to have the highest quality of life or fostering innovation. However, the increasing world population and a changing climate have made eco-friendly living a priority for residents and city leaders alike. This has now led to cities competing to be the most environmentally friendly. The global movement towards more sustainability is also pushing for more innovation and change. Here are 11 of the world’s most eco-friendly cities as well as a brief overview of what they’ve done to achieve that status.
Reykjavik is the capital of Iceland and ranks among the most eco-friendly cities in the world. This is partially due to their harnessing of abundant geothermal energy for power and keeping the freezing northern city warm. Their small population is densely packed into the city, so people can get around by walking, biking or via public transit.
The city is offering incentives to encourage people to drive electric cars, such as free parking and lower taxes. They’re also going the old-fashioned route by encouraging the other 96 percent of the population to ride public transit, including their brand-new hydrogen powered buses.
Vancouver is sandwiched between the ocean and the mountains, though the surrounding coast is covered in forests. The local administration found out that the city’s environmental footprint was just too big to be sustainable and decided to make some real changes. As a result of these initiatives, the city now has the lowest greenhouse gas emissions level for any major city in North American city.
They are doing yet even more to reduce the city’s footprint. For example, the city is doing a lot to attract clean technology companies and increase the number of green jobs. They’ve seen a 23 percent in green jobs since 2013. They’re also encouraging local food production so they can feed people without wasting energy transporting food from thousands of miles away.
San Francisco, California
San Francisco is one of the most environmentally conscious cities in the world. Where San Francisco stands out is the sheer number of ways it is lowering its ecological footprint from the top down.
For example, consumers and city agencies systematically shop for organic and locally sourced food. Living waste-free seems like a dream, but the city itself has that as a goal by 2020. The city is roughly eighty percent of the way there. They’ve dramatically reduced waste and increased recycling, while they encourage businesses and individuals alike to switch to reusable containers. As a matter of fact, San Francisco became the first city in the US to completely ban plastic bottles. A large part of the organic waste produced in the city is turned into compost and used by local farmers.
San Francisco is also ahead of the curve in terms of renewable energy. The city has many zero emissions and hybrid electric buses. Solar installations in the Bay Area are surprisingly common. This is in part because they pay themselves off in less than seven years when you take rebates and tax credits into account. For example, San Francisco’s GoSolarSF program encourages people to install solar panels. The average homeowner receives 300 dollars per kilowatt and up to 2000 dollars per kilowatt if the residents are considered low income. This will remain in effect even if the federal tax rebates for solar installations start to phase out.
Another side effect of the eco-conscious population is that renewable energy becomes a selling point for properties that have it. The best solar companies in the Bay Area, including firms like Semper Solaris, install quality solar panel systems that add value to your home. They also make it easier for people in the region to afford systems by adjusting them to their particular needs. Not only that, but they also offer battery storage so users can still use solar energy when the sun isn’t shining. The increased home value is based in part on the future reduced utility bills the homeowners expect to receive.
Helsinki sits on the Gulf of Finland. It stands out for its delicate balance between eco-friendliness and tourism. Roughly three in four hotel rooms in the city are certified as eco-friendly. Most of the remainder have some environmental impact reduction plan in place to reduce energy consumption, minimize waste, and lower the environmental impact of their food and water supply.
The city makes use of wind energy and solar power. The “green district” Viiki is an experiment in sustainability. This is why the first solar powered apartment building in Finland is located here.
Capetown, South Africa
Capetown is another example of a city that has gone above and beyond to reduce its ecological footprint. One of the ways they are doing so is by reducing their reliance on unsustainable energy sources and turning to alternatives like solar energy instead. And it has paid off, especially when considering the amount of sunlight the city enjoys every year.
They’ve also heavily invested in wind power. As a matter of fact, the city has started focusing on building wind farms since 2008. And the city made it a goal to meet 10% of its energy needs using renewable energy sources by 2020, which could very well be possible given all the different initiatives they’ve started.
They’re also trying to pattern the behavior and habits of residents and push them to adopt a more outdoorsy lifestyle. Not only that, but they’re facilitating bike transport by allowing bicycles for free on their My Citi express bus service.
Berlin is one of the most famous and historical cities in the world, and the reason why it made that list is also tied to history. After WWI, residents in the city were forced to become very self-reliant, and had to find ways to grow and raise their own food, which is a tradition that continues to this day. Germans in general also value their green spaces and gardening.
Berlin is also doing a lot to accommodate electric vehicles owners by adding over 400 charging stations around the country. They’re also trying to raise awareness among gas vehicle owners and trying to sway them into going electric. Not only that, but Berliners also are more prone to using public transit or sharing vehicles then using their personal car.
This is the second west coast city in this list, and it shouldn’t come as a surprise considering that the west coast is and has always been a hotbed for the environmentalist movement. And while the city’s population keeps on growing, they are continually working to minimize the effect of the city’s activity on the environment. They also put a ban recently on plastic bags to curb their effect on the ecosystem, with other cities on the west coast following suit.
But one of the main reasons why Portland made this list is the people of the city. Environmental consciousness is part of the city’s DNA, and Portlanders take it to the next level. Did you know that roughly 25% of the city’s workers do their commute through carpooling, biking, or public transit? Out of all the people in the city, 8% also stated that they only use their bike for transportation. This is thanks in part to the city’s massive bike path and lane system.
The city also gets 33% of its energy from renewable sources and recuperates roughly 1,200,000 tons from the 2,434,840 tons of waste they produce every year, which is pretty impressive for a city its size. The city also managed to cut their carbon emissions by as much as 17%, even with the increasing population.
Amsterdam is bar none one of the most avant-garde cities when it comes to environmental initiatives, and has worked for a long time to limit its energy consumption from unsustainable sources. As a matter of fact, the city was one of the first to introduce widespread sustainability initiatives with a goal to reach a wide variety of benchmarks by the year 2020.
One of the main things people remember when they come to the city is the sheer number of cyclists, and Amsterdammers do love their bikes. But the city also did a lot to popularize electric vehicles, and owners can charge their vehicles in one of the 300 charging ports you’ll find all over the city. People in the city are also increasingly turning to solar energy and sustainable local farming. More people from the city are starting to grow their own food as well.
With over 50 bridges and 14 islands, Stockholm has done a lot to improve the city and allow citizens to live a more sustainable life. The city also set a goal to eliminate the use of fossil fuels by 2040. In addition, they’re getting assistance from the European Union to become a smarter city.
One of the ways the city has managed to be more energy efficient was by turning to biofuels, which are created from the city’s sewage waste. A large portion of cars in the city are powered using this biofuel. They also managed to recuperate some of the heat generated by their massive stadium. This heat can be used to heat over 1000 units in the city.
The capital of Denmark has also started to build a reputation as an ecofriendly city, and is taking steps to continue in the right direction and support eco-friendly initiatives. And this is mainly due to the city’s sustained and massive investments in clean infrastructure and renewable energy sources.
They also set the lofty goal of becoming the first major city in the world to achieve CO? neutrality by the year 2020. And residents in the city are also doing their part for this goal to become a reality. Less than a third of households in the city own a car, and people in Copenhagen are also big on cycling. As a matter of fact, it’s not uncommon for hotels in the city to provide guests with a bicycle upon arrival. The city also has one of the most extensive bike lane networks in Europe.
Another thing that sets the city apart is how many people choose to eat organic there. About a quarter of all the food sold in the city’s markets is organic, and they’re also big proponents of local farming, which further reduces their carbon footprint.
Considering the amount of natural beauty Brazil is nestled in, it shouldn’t be a surprise to see a Brazilian city on this list. Curitiba might not be as well-known as Rio and Sao Paulo, but it is known as one of the world’s green capitals. Where they excel is when it comes to recycling. As a matter of fact, it is said that about 70% of the waste produced in the city is recycled in the form of derived products or energy.
The city also puts a lot of importance on urban planning and has one of the best public transit systems in South America. Most people in the city rely on public transport too. The city is also not overly developed and has tons of green spaces with over 16 parks and 14 forests near and around the city’s core.
Presence of trees make a city appear more vibrant and eco-friendly
To incentivize cleanliness around the city, they installed a program that allows people to return and exchange recyclables for things like tokens, sweets, snacks, and cash. Not only does it encourage people to recycle more, but the program is also feeding over 7000 people in need in the city.
The most eco-friendly cities in the world are seeking to provide a better environment for residents while reducing their impact on the planet, and they’re providing an example to the world that the rest can follow. We can only expect the trend to grow from now and into the future, and for residents from cities all around the world to start pushing for more green initiatives where they are.
Disposal of cooking oil is not an easy task. If you try to drain it, it will block your sink drains and cause you immense plumbing problems. Throwing it away is also not a good idea because it causes damage to the environment. Cooking oil cannot go to your usual recycle trash bin like other trash because the processes of recycling it are different. However, there are better ways of recycling cooking oil without harming the environment. You can have it recycled. If you are not able to do it by yourself, there are companies that offer cooking oil recycling services.
Benefits of recycling cooking oil
Recycling companies, like MBP Solutions, turn cooking oil into other products like stock feed, cosmetics and biofuel. They also filter the oil for reuse. If you are not in any position to recycle your cooking oil, do not drain it down the sink or throw it in your waste bin. Wrap your cooking oil in a tight jar, make sure there are no spills and call the right people to come and collect it. MBP Solutions recycles both commercial and residential cooking oils.
Recycling cooking oil comes with several benefits. The technology used to recycle the oil is advanced and the final products help in both businesses and homes.
Below are some of the major benefits of recycling of cooking oil:
Recycling cooking oil turns it into renewable energy used in many manufacturing firms for processing their products. One of the most notable fuels is biodiesel, which is from used oils, grease, animal fats and vegetable oils among others. Vehicles that use diesel can use this fuel effectively and businesses that use diesel-powered machines can use the fuel without any fear of harmful emissions.
We all need a clean environment and it is not what we always get. Fuels are some of the major contributor to health hazards because of emissions. Petro-diesel is very toxic as compared to biodiesel. Biodiesel is eco-friendly and does not damage a vehicle’s engine. Petro-diesel on the other hand, produces chemical compounds like sulphur that are acidic. This acid can spoil the engine. Biodiesel production is green in nature and keeps everything safe.
Recycling cooking oil saves costs in many ways. At home, you can reduce your disposal costs by calling a recycling company to come for your waste oil. If you try to dispose of the oil by yourself, you may end up spending more on extra waste bins, transportation and special disposal procedures.
Companies that use recycled oil have a chance of preventing their equipment from spoiling faster than they did before the recycled oil. Maintenance costs go down and recycled oil like biodiesel is much cheaper as compared to the other kinds of imported fuels.
Disposing of waste materials and recycling them is one way of creating jobs for the masses. Instead of using that money to import petro-diesel, the government uses the money to employ more people to recycle oil into more beneficial biodiesel.
Make money out of it
You can make an extra buck out of disposing your used oil. Instead of throwing your oil away, look for companies that recycle the oil and pay you for it. This will also save you on transport costs to go and dispose of your oil, because the recycling companies come to pick it up.
Wrapping it up
The most important factor about recycling is that we are working towards one goal. That goal is to maintain a greener, healthier and cleaner environment. That is our goal and recycling cooking oil is one way of doing that.
Agriculture plays an important role in the economies of most of the countries in the Middle East. The contribution of the agricultural sector to the overall economy varies significantly among countries in the region, ranging, for example, from about 3.2 percent in Saudi Arabia to 13.4 percent in Egypt. Large scale irrigation is expanding, enabling intensive production of high value cash and export crops, including fruits, vegetables, cereals, and sugar.
The term ‘crop residues’ covers the whole range of biomass produced as by-products from growing and processing crops. Crop residues encompasses all agricultural wastes such as bagasse, straw, stem, stalk, leaves, husk, shell, peel, pulp, stubble, etc. Wheat and barley are the major staple crops grown in the Middle East region. In addition, significant quantities of rice, maize, lentils, chickpeas, vegetables and fruits are produced throughout the region, mainly in Egypt, Syria, Saudi Arabia and Jordan.
Agricultural Wastes in the Middle East
Large quantities of agricultural wastes are produced annually in the Middle East, and are vastly underutilised. Current farming practice in the Middle East is usually to plough these residues back into the soil, or they are burnt, left to decompose, or grazed by cattle. These residues could be processed into liquid fuels, solid fuels or thermochemically processed to produce electricity and domestic heat in rural areas.
Date palm biomass is an excellent resource for charcoal production in Middle East
Date palm is one of the principal agricultural products in the arid and semi-arid region of the world, especially Middle East and North Africa (MENA) region. The Arab world has more than 84 million date palm trees with the majority in Egypt, Iraq, Saudi Arabia, Iran, Algeria, Morocco, Tunisia and United Arab Emirates.
Date palm trees produce huge amount of agricultural wastes in the form of dry leaves, stems, pits, seeds etc. A typical date tree can generate as much as 20 kilograms of dry leaves per annum while date pits account for almost 10 percent of date fruits. Some studies have reported that Saudi Arabia alone generates more than 200,000 tons of date palm biomass each year.
In Egypt, crop residues are considered to be the most important and traditional source of domestic fuel in rural areas. These crop residues are by-products of common crops such as cotton, wheat, maize and rice. The total amount of residues reaches about 16 million tons of dry matter per year.
Cotton residues represent about 9% of the total amount of residues. These are materials comprising mainly cotton stalks, which present a disposal problem. The area of cotton crop cultivation accounts for about 5% of the cultivated area in Egypt.

Energy crops, such as Jatropha, can be successfully grown in arid regions for biodiesel production. Infact, Jatropha is already grown at limited scale in some Middle East countries and tremendous potential exists for its commercial exploitation.
Date palm is one of the principal agricultural products in the arid and semi-arid region of the world, especially Middle East and North Africa (MENA) region. There are more than 120 million date palm trees worldwide yielding several million tons of dates per year, apart from secondary products including palm midribs, leaves, stems, fronds and coir. The Arab world has more than 84 million date palm trees with the majority in Egypt, Iraq, Saudi Arabia, Iran, Algeria, Morocco, Tunisia and United Arab Emirates.
Date palm biomass is found in large quantities across the Middle East
Egypt is the world’s largest date producer with annual production of 1.47 million tons of dates in 2012 which accounted for almost one-fifth of global production. Saudi Arabia has more than 23 millions date palm trees, which produce about 1 million tons of dates per year.
Biomass Potential of Date Palm
Date palm trees produce huge amount of agricultural wastes in the form of dry leaves, stems, pits, seeds etc. A typical date tree can generate as much as 20 kilograms of dry leaves per annum while date pits account for almost 10 percent of date fruits. Some studies have reported that Saudi Arabia alone generates more than 200,000 tons of date palm biomass each year.
Date palm is considered a renewable natural resource because it can be replaced in a relatively short period of time. It takes 4 to 8 years for date palms to bear fruit after planting, and 7 to 10 years to produce viable yields for commercial harvest. Usually date palm wastes are burned in farms or disposed in landfills which cause environmental pollution in dates-producing nations. In countries like Iraq and Egypt, a small portion of palm biomass in used in making animal feed.
The major constituents of date palm biomass are cellulose, hemicelluloses and lignin. In addition, date palm has high volatile solids content and low moisture content. These factors make date biomass an excellent waste-to-energy resource in the MENA region.
Technology Options for Date Palm Biomass Utilization
A wide range of thermal and biochemical technologies exists to tap the energy stored in date palm biomass to useful forms of energy. The low moisture content in date palm wastes makes it well-suited to thermochemical conversion technologies like combustion, gasification and pyrolysis which may yield steam, syngas, bio oil etc.
On the other hand, the high volatile solids content in date palm biomass indicates its potential towards biogas production in anaerobic digestion plants, possibly by codigestion with sewage sludge, animal wastes and/and food wastes. The cellulosic content in date palm wastes can be transformed into biofuel (bioethanol) by making use of the fermentation process.
The highly organic nature of date palm waste makes it highly suitable for compost production which can be used to replace chemical fertilizers in date palm plantations. Thus, abundance of date palm trees in the MENA and the Mediterranean region, can catalyze the development of biomass and biofuels sector in the region.
There’s no doubt that Covid-19 has taken a human and socio-economic toll over the course of the last six months, with more than 10 million cases and 500,000 deaths recorded so far. However, the pandemic has always provided moments of hope and economy across the globe, from the boom in ecommerce and the rise of remote working to the unexpected 8% emissions reduction reported in the UK. These trends have also been impactful across the globe, and there’s no doubt that they have the potential to sustain significant and positive change into the future.
What is a Green Economy and Why Should the World Care?
Of course, the Covid-19 outbreak came on the back of global environmental protests by organisations such as Extinction Rebellion, which sought to drive radical change and introduce a green economy that would make the UK carbon neutral by 2025.
This was deemed to be incredibly ambitious by some commentators, although the current Conservative government has pledged to create a greener, carbon neutral economy by 2050.
While regulations and multilateral agreements such as the Paris Climate Change Agreements take care of the first element of this, it’s socially responsible investment that drives the second.
The best example of the latter exists in the form of investment in renewable technology, which is arguably the single most important dynamic for future infrastructure spending throughout the global community.
Can Covid Trigger Increased Green Technology Spending?
With this in mind, the importance of green economics and increased renewable technology spending is clear, while the sharp decline in emissions during the coronavirus outbreak has raised hopes that a green global economy may be on the horizon.
Still, there’s no doubt that fossil fuel consumption is set to decline incrementally in the coming years, and this is definitely a factor when appraising the issues faced by oil of late.
Ultimately, these facts hint at a greener and more sustainable future, and it cannot be denied that most developed economies were investing in renewable energy sources at record levels prior to the pandemic.
The question that remains, of course, is to what degree the recent emissions reductions across the globe have been inspired by such changes? The answer is telling, particularly if it turns out the reduction in CO2 emissions over the course of the last two months was solely driven by the widespread lockdown measures that curbed road and air travel.
Regardless, now is clearly the ideal time to push a greener agenda and continue laying the foundations for a more sustainable future.
