Meeting an ever increasing demand for food/feed/energy and managing waste have become two of the major global challenges. The global world population is estimated to increase from 7.3 billion in 2015 to 9.7 billion in 2050. Approximately one third of the global food produced for human composition is wasted. Currently, approximately 1.3 billion metric tons of waste are disposed with significant environmental impact as far as greenhouse gases and economic footprints and the current waste management practices are not costly sustainable.

Increase in Global Energy Demand

Global energy demand is estimated to increase from 524 Quadrillion btu in 2010, to 820 Quadrillion btu by 2040 (a 56% increase). Similarly, global demand of food and animal products are projected to increase by 70-100% and 50-70%, respectively, by 2050. To cope up with the demand for animal products, a substantial increase in nutritious animal feed is needed.

On one hand, the production of conventional feedstuff such as soybean meal and fish meal is reported as the major contributor to land occupation, ocean depletion, climate change, water and energy consumption. Moreover, such conventional animal feedstuff are not only limited in supply but also are becoming more expensive over the years. Additionally, there is an already strong and increasing competition for resources such as food, feed and biofuel production.

Need for alternative non-conventional source of food, feed, and fuel

Thus there is a pressing need for identifying and exploring the potential of alternative non-conventional source of food, feed, and fuel, which are economically viable, environmentally friendly, and socially acceptable.

By 2030 the Bio-based Economy is expected to have grown significantly. A pillar of this is biorefining, the sustainable processing of biomass into a spectrum of marketable products and energy. To satisfy this demand biorefineries need to be better integrated, flexible and operating more substantially. This means that a major yield, more efficient use of nutrients and water and greater pest and disease resistance should be achieve.

Zena Fly: A Startup Worth Watching

In this context an Italian-based start-up, Zena Fly, designed an innovative process for the future integrated biorefinery by mimicking nature’s ability. In fact, Zena Fly utilizes the natural insect life cycle to manage large quantity of organic waste produced in urban and industrial context, in order to generate sustainable and valuable by-products. The project of three young entrepreneurs foresees a combined bio-refinery where waste is turned into high-quality by-products by the anaerobic insect digestion.

The Concept

The basic concept is to convert waste into high-valuable products utilizing the black soldier flies (H. illucens), a now globally distributed insect. With a modern technique, the typical insect life cycle of these insects can be utilized in order to manage urban and industrial waste. The voracious larvae can reduce by more than 40-70% (based on the nature of the substrate-waste) the substrate where reared (waste) within 12-14 days.

From the anaerobic waste digestion, large quantity of fine protein meal for feed composition (more than 50-60% in protein), fat, fertilizing oil and other by-products of great interest such as chitin, and high-quality biofuel are then extracted.

Since the adult fly do not feed, and do not fly around for feeding, these animals are exceptionally valuable from a sanitary perspective (larvae has been demonstrate to reduce/eliminate E.coli and Salmonella).

Business Model

Zena Fly business model foresees to replicate their integrated biorefineries next to any waste management companies or industrial production areas where large quantity of waste need to be reduced and transformed. This is a win/win operation, where the waste management cost would be cut in half and the process will generate appealing opportunities for investments in a market where the increasing demand is already way higher than the products availability.

Zena Fly is now seeking for the right partner-investor in order to scale up quickly. For more information, please visit www.zena-fly.com or email us on info@zena-fly.com

Composting in Qatar: An Overview

  By | | , ,
3 Comments

Composting in Qatar is mainly done at the Domestic Solid Waste Management Centre (DSWMC) in Mesaieed, which houses the largest composting facility in the country and one of the largest in the world.  The waste that enters the plant initially goes through anaerobic digestion, which produces biogas that can power the facility’s gas engine and generators, followed by aerobic treatment which yields the final product.

Two types of compost are generated: Grade A (compost that comes from green waste, such as yard/park trimmings, leftovers from kitchen or catering services, and wastes from markets) and Grade B (compost produced from MSW).  The plant started its operation in 2011 and when run at full capacity is able to process 750 tons of waste and produce 52 tons of Grade A compost, 377 tons of Grade B compost, liquid fertilizer which is composed of 51 tons of Grade A compost and 204 tons of Grade B compost, and 129 tons of biogas.

benefits-composting

This is a significant and commendable development in Qatar’s implementation of its solid waste management plan, which is to reduce, reuse, recycle and recover from waste, and to avoid disposing in landfills as much as possible.  However, the large influx of workers to Qatar in the coming years as the country prepares to host the World Cup in 2022 is expected to substantially increase solid waste generation and apart from its investments in facilities like the composting plant and in DSWMC in general, the government may have to tap into the efforts of organizations and communities to implement its waste management strategy.

Future Outlook

Thankfully, several organizations recognize the importance of composting in waste management and are raising awareness on its benefits.  Qatar Green Building Council (QGBC) has been actively promoting composting through its Solid Waste Interest Group.  Last year, they were one of the implementers of the Baytna project, the first Passivhaus experiment in the country.

This project entails the construction of an energy-efficient villa and a comparative study will be performed as to how the carbon footprint of this structure would compare to a conventional villa.  The occupants of the Passivhaus villa will also be made to implement a sustainable waste management system which includes composting of food waste and garden waste, which is meant to lower greenhouse gas emissions compared to landfilling.

Qatar Foundation is also currently developing an integrated waste management system for the entire Education City and the Food Services group is pushing for composting to be included as a method to treat food and other organic waste.  And many may not know this but composting can be and has been done by individuals in their own backyard and can even be done indoors with the right equipment.

Katrin Scholz-Barth, previous president of SustainableQatar, a volunteer-based organization that fosters sustainable culture through awareness, skills and knowledge, is an advocate of composting and has some great resources on how to start and maintain your own composting bin as she has been doing it herself.

A simple internet search will also reveal that producing compost at home is a relatively simple process that can be achieved with minimal tools.  At present, very few families in Qatar are producing their own compost and Scholz-Barth believes there is much room for improvement.

As part of its solid waste management plan as stated in the National Development Strategy for 2011-2016, Qatar aims to maintain domestic waste generation at 1.6 kg per capita per day.  This will probably involve encouraging greater recycling and reuse efforts and the reduction of waste from its source.

It would also be worthwhile to include programs that will promote and boost composting efforts among institutions, organizations and individuals, encouraging them with the fact that apart from its capability of significant waste diversion from landfills, composting can also be an attractive source of income.

Food Waste Management in UK

  By | | , ,

Food waste in the United Kingdom is a matter of serious environmental, economic and social concern that has been attracting widespread attention in recent years. According to ‘Feeding the 5K’ organisation, 13,000 slices of crusts are thrown away every day by a single sandwich factory. More recently, Tesco, one of the largest UK food retailers, has published its sustainability report admitting that the company generated 28,500 tonnes of food waste in the first six months of 2013. TESCO’s report also state that 47% of the bakery produced is wasted. In terms of GHG emissions, DEFRA estimated that food waste is associated with 20 Mt of CO2 equivalent/year, which is equivalent to 3% of the total annual GHG emissions.

Food-Waste-UK

Globally, 1.2 to 2 billion tonnes (30%-50%) of food produced is thrown away before it reaches a human stomach. Food waste, if conceived as a state, is responsible for 3.3 Bt-CO2 equivalent/year, which would make it the third biggest carbon emitter after China and USA.

What makes food waste an even more significant issue is the substantially high demand for food which is estimated to grow 70% by 2050 due to the dramatic increase of population which is expected to reach 9.5 billion by 2075. Therefore, there is an urgent need to address food waste as a globally challenging issue which should be considered and tackled by sustainable initiatives.

A War on Food Waste

The overarching consensus to tackle the food waste issue has led to the implementation of various policies. For instance, the European Landfill Directive (1999/31/EC) set targets to reduce organic waste disposed to landfill in 2020 to 35% of that disposed in 1995 (EC 1999).

More recently, the European Parliament discussed a proposal to “apply radical measures” to halve food waste by 2025 and to designate the 2014 year as “the European Year Against Food Waste”. In the light of IMechE’s report (2013), the United Nations Environment Programme (UNEP) in cooperation with FAO has launched the Save Food Initiative in an attempt to reduce food waste generated in the global scale.

In the UK, WRAP declared a war on food waste by expanding its organic waste programme in 2008 which was primarily designed to “establish the most cost-effective and environmentally sustainable ways of diverting household food waste from landfill that leads to the production of a saleable product”. DEFRA has also identified food waste as a “priority waste stream” in order to achieve better waste management performance.

In addition to governmental policies, various voluntary schemes have been introduced by local authorities such as Nottingham Declaration which aims to cut local CO2 emissions 60% by 2050.

Sustainable Food Waste Management

Engineering has introduced numerous technologies to deal with food waste. Many studies have been carried out to examine the environmental and socio-economic impacts of food waste management options. This article covers the two most preferable options; anaerobic digestion and composting.

In-vessel composting (IVC) is a well-established technology which is widely used to treat food waste aerobically and convert it into a valuable fertilizer. IVC is considered a sustainable option because it helps by reducing the amount of food waste landfilled. Hence, complying with the EU regulations, and producing a saleable product avoiding the use of natural resources.

IVC is considered an environmentally favourable technology compared with other conventional options (i.e. landfill and incineration). It contributes less than 0.06% to the national greenhouse gas inventories. However, considering its high energy-intensive collection activities, the overall environmental performance is “relatively poor”.

Anaerobic Digestion (AD) is a leading technology which has had a rapidly growing market over the last few years. AD is a biologically natural process in which micro-organisms anaerobically break down food waste and producing biogas which can be used for both Combined Heat & Power (CHP) and digestate that can be used as soil fertilizers or conditioners. AD has been considered as the “best option” for food waste treatment. Therefore, governmental and financial support has been given to expand AD in the UK.

AD is not only a food waste treatment technology, but also a renewable source of energy. For instance, It is expected that AD would help the UK to meet the target of supplying 15% of its energy from renewable sources by 2020. Furthermore, AD technology has the potential to boost the UK economy by providing 35,000 new jobs if the technology is adopted nationally to process food waste. This economic growth will significantly improve the quality of life among potential beneficiaries and thus all sustainability elements are considered.

Electrical Waste Collection Strategies in the UK

When disposing of small electrical items from the home, most householders only have the option of visiting their local recycling facility to drop them off. However, in order to meet recycling targets, local authorities in the UK are now considering kerbside (or curbside) collections of small domestic appliances. This is expected to help prevent small electrical items being placed into the general waste/refuse containers from households.

electrical-waste-uk

This waste stream has become a priority as figures show that the average amount of WEEE (waste electrical and electronic equipment) recycled per person is only 1.3kg. The original WEEE directive targeted 4kg per person, as a recycling rate, so there is a considerable shortfall. It is important that householders find it easy to recycle their items in order to increase the rates.

Initial trials have taken place to assess the viability of these kerbside collections and the following conclusions were made:

  • On collections, small electrical items were often damaged, so the reuse of items was less likely.
  • Levels of recycling were encouraging at 140 grams per household.
  • The monetary value of the separated materials of the small items showed that a positive net value could be achieved.

Whilst the potential reuse of small electrical items was reduced it was a positive that local authorities could generate revenues from the collections. Quarterly or bi-annual collection frequencies would ensure volumes of equipment on the collections were maximised. Due to the success of the trials, the UK is likely to see more and more local authorities adopt some form of collection schedule for small electrical waste items.

An old refrigerator uses almost four times the electricity of a new one

Larger electrical items such as washing machines and fridge freezers pose a different collection issue. Some local authorities offer a collection service for bulky electrical items, however due to their size, weight and manpower requirements there is often a charge. As with smaller electrical items, you can deliver these to the local recycling facility, but you may not be able to fit these into your own vehicle. It is best to check with the local recycling facility on the options available and possibly even if they allow large, commercial sized vehicles onto site.

The collection of electrical wastes from households in the UK will ultimately increase the amount of electrical waste being recycled in the UK. It will also further promote the recycling of such items instead of placing them into general waste containers. Going forward it is hoped that more local authorities will adopt a collection schedule even if only bi-annually from their local householders.

Guide to Effective Waste Management

The best way of dealing with waste, both economically and environmentally, is to avoid creating it in the first place. For effective waste management, waste minimization, reuse, recycle and energy recovery are more sustainable than conventional landfill or dumpsite disposal technique.

Olusosun is the largest dumpsite in Nigeria

Waste Minimization

Waste minimization is the process of reducing the amount of waste produced by a person or a society. Waste minimization is about the way in which the products and services we all rely on are designed, made, bought and sold, used, consumed and disposed of.

Waste Reuse

Reuse means using an item more than once. This includes conventional reuse where the item is used again for the same function and new-life reuse where it is used for a new function. For example, concrete is a type of construction waste which can be recycled and used as a base for roads; inert material may be used as a layer that covers the dumped waste on landfill at the end of the day.

Waste Recycling

Recycling of waste involves reprocessing the particular waste materials, including e-waste, so that it can be used as raw materials in another process. This is also known as material recovery. A well-known process for recycling waste is composting, where biodegradable wastes are biologically decomposed leading to the formation of nutrient-rich compost.

Waste-to-Energy

As far as waste-to-energy is concerned, major processes involved are mass-burn incineration, RDF incineration, anaerobic digestion, gasification and pyrolysis. Gasification and pyrolysis involves super-heating of municipal solid waste in an oxygen-controlled environment to avoid combustion. The primary differences among them relate to heat source, oxygen level, and temperature, from as low as about 300°C for pyrolysis to as high as 11 000°C for plasma gasification. The residual gases like carbon dioxide, hydrogen, methane etc are released after a sophisticated gas cleaning mechanism.

MSW incineration produce significant amounts of a waste called bottom ash, of which about 40% must be landfilled. The remaining 60% can be further treated to separate metals, which are sold, from inert materials, which are often used as road base.

The above mentioned techniques are trending in many countries and region. As of 2014, Tokyo (Japan) has nineteen advanced and sophisticated waste incinerator plants making it one of the cleanest cities. From the legislature standpoint, the country has implemented strict emission parameters in incinerator plants and waste transportation.

The European Union also has a similar legislature framework as they too faced similar challenges with regards to waste management. Some of these policies include – maximizing recycling and re-use, reducing landfill, ensuring the guidelines are followed by the member states.

Singapore has also turned to converting household waste into clean fuel, which both reduced the volume going into landfills and produced electricity. Now its four waste-to-energy plants account for almost 3% of the country’s electricity needs, and recycling rates are at an all-time high of 60%. By comparison, the U.S. sent 53% of its solid waste to landfills in 2013, recycled only 34% of waste and converted 13% into electricity, according to the US Environmental Protection Agency.

Trends in Waste Collection

Since the municipal solid waste can be a mixture of all possible wastes and not just ones belonging to the same category and recommended process, recent advances in physical processes, sensors, and actuators used as well as control and autonomy related issues in the area of automated sorting and recycling of source-separated municipal solid waste.

Automated vacuum waste collection systems that are located underground are also actively used in various parts of the world like Abu Dhabi, Barcelona, Leon, Mecca and New York etc. The utilization of the subsurface space can provide the setting for the development of infrastructure which is capable of addressing in a more efficient manner the limitations of existing waste management schemes.

AI-based waste management systems can help in route optimization and waste disposal

This technique also minimizes operational costs, noise and provides more flexibility. There are various new innovations like IoT-enabled garbage cans, electric garbage trucks, waste sorting robots, eco dumpster and mechanisms etc are also being developed and deployed at various sites.

Conclusion

Waste management is a huge and ever growing industry that has to be analyzed and updated at every point based on the new emergence of threats and technology. With government educating the normal people and creating awareness among different sector of the society, setting sufficient budgets and assisting companies and facilities for planning, research and waste management processes can help to relax the issues to an extent if not eradicating it completely. These actions not only help in protecting environment, but also help in employment generation and boosting up the economy.

Recycling: Where to Start in Reducing Your Waste?

  By | | , , ,

Millions and billions of garbage are accumulated every year. In America alone, each individual produces up to 4 pounds of waste material every day. Improper disposal of this garbage is harmful not only to you but also to everyone around you. Waste from landfills can emit greenhouse gases, pollute the soil, and can contaminate your drinking water.

However, in a simple way, such as recycling, you can make a difference. You can recycle your garbage in various ways, including reselling, donating, collecting, manufacturing, etc. Recycling is a lifestyle you can choose that requires a vast amount of dedication and a sense of responsibility.

recycling-waste

Here are some tips and tricks that can help you start your recycling journey.

What  You Can Recycle

First, you need to distinguish what garbage you can and cannot recycle.

Recyclable

  1. Plastic – Any plastic containers and bottles with the recycling symbol, and inside are the numbers 1 or 2.
  2. Paper Products – Items including phonebooks, magazines, mails, newspapers, food boxes, cardboard boxes, and printer paper.
  3. Glass – Objects like food containers, bottles, and jars, which are emptied and rinsed.
  4. Metal – Mainly aluminum cans, steel cans, tin, and other metals as long as it’s also empty and rinsed.

Non-Recyclable

  1. Plastic shopping bags
  2. Plastic food wrappings
  3. Plastic straws and silverware
  4. Foam containers, cups, and egg cartons
  5. Soiled food or biological waste
  6. Broken glasses
  7. Medical waste
  8. Dirty diapers
  9. Ink cartridges
  10. Phones

There are still more items to be included in the list, feel free to read the label or go online for them. It’s good to make it a habit to check if an item is recyclable or not.

Purchase Your Recycling Bins

After knowing what garbage is recyclable and non-recyclable, you can now buy your recycling bins. You can shop in malls or other marketplaces that offer bins in your desired size and shape at affordable prices. Some bins have a recycling logo that would help you to easily distinguish it from your other trash cans.

The basic rule in how many bins you should acquire depends on how many trash cans you have in your household. Also, set up your recycling bins next to your trash cans so that every time you throw an item away, you will be reminded to check if it’s recyclable or not. Remember not to use plastic bags in recycling because they are not recyclable.

Aside from your home, you can also keep recycling bins in your car and your office at work. Wherever you are, you can always sort and recycle your garbage.

Find Your Local Drop-Off Location

Depending on where you live, there may be different rules on what you can recycle and how to prepare your recycled items. Moreover, public drop-off areas are also important information to know together with the local garbage collection schedule.

Some states would allow you to leave your recycled items in the curbside, but if not, be sure to know where the designated areas are so that you can dump your recyclables before garbage collectors pick them up. The collection schedule could either be once a week or once every other week. It wholly depends on where you live.

Be sure to inquire to your local government or information desk about these rules and instructions before you start recycling. Print out the vital information and instructions, and post them somewhere visible so that you can’t forget about them.

Other Actions to Consider

Recycling your garbage helps in reducing your household waste and lowering your carbon footprint. But besides recycling, there are many other activities and practices you can do to help the society and the environment more. Remember to reduce, reuse, and recycle the items in your household instead of immediately throwing them out.

You can avoid buying or using single-use plastics to reduce the waste you produce. Another trick is to use recyclable bags instead of paper and plastic bags. Utilize your jars for your leftovers instead of plastic containers. You can also create your garden fertilizer by using food waste and other compostable garbage to set up a compost pile.

However, for wastes such as expired medicines, one should not, in any way, recycle and reuse expired or unused medicines as they can pose a risk to one’s health and safety. Throwing it anywhere is also harmful to the environment.

There’s a specific disposal process you must follow, which includes mixing the medicine with cat litter or referring to the FDA’s Flush List. Visit BuzzRx to learn more about proper medicine disposal.

Takeover

The way you live can impact the world and the environment. By recycling, you can help lessen waste, conserve resources, and not contribute to the pollution already prevalent in our world. No matter how tedious recycling can be, remember that it will be developed into a good habit that will help improve the society, environment, and especially yourself.

The Benefits of Applying Compost to Your Garden

  By | | , ,
2 Comments

Composting is a natural process of recycling food waste, lawn and garden waste along with other organic matter such as leaves and newspapers. It is all natural resulting in improved soil quality, nutrient recycling and water conservation.

You are able to fertilize and improve the soil with natural ingredients that provide plant nutrients and beneficial microbial and other organisms, such as fungal mycelium and earthworms, that enhance the soil environment.

benefits of applying compost in garden

The Advantages of Applying Compost

There is a phrase “Black Gold” and that exactly is what compost material is. Compost that you have generated in your own backyard by processing food waste, lawn clippings, ripped up papers, especially newspapers, leaf litter. Mixing the greens and the browns biodegradable waste products that are generated in our home or around the yard.

This compost material can be spread across the garden soil, dug in and used to supplement nutrients in the growing beds of our gardens. First and foremost, you will be adding microbial material to your soils that will bring more life and energy to your soil and ultimately to your plants. It’s a type of food for the soil.

It means you will not need to use commercial and artificial chemicals on your souls to boost the growth. That will save you hard earned cash. It will protect you and your family from artificial chemicals. The compost will also add to your mulch layer which is designed to suppress weeds or the unintended plants that pop up in everyone’s garden. This also means no pesticide usage to kill the weeds either. That is another money saving aspect and protection for you from pesticides.

All the while, the richer soil will give rise to greater microbial diversity within your soil. Greater diversity will mean a more efficient and faster processing of soil maturation. This in turn will create the perfect environment for the vegetable and flower garden.

benefits-composting

By these advantages, the soil structure will be improved that soil organisms and root structures will move more freely through the soil substrata with less stress and resistance. By creating a healthier plant root environment, the soil will be easier also for you to cultivate and care for. Water will penetrate more easily and the compost material will also help retain the soil moisture. At the same time, the compost helps maintain an ideal pH level in the soil that is optimum for plant growth.

The water holding capacity will be enhanced overall. As mentioned above, not just easing entry of water into the soil, but retaining it within the soil layer means there will not be the hardening or crusting of the very top soil layer that makes it hard and even impossible for water penetration. If this occurs, water will simply runoff the garden and even wash away clumps of soil. A healthy soil will also conserve water in your garden environment. It is a win-win situation.

sustainable options to turn your garden greener.

To summarise, the key benefits of using compost are as follows:

  • Enriched soil structure
  • Enhanced soil biodiversity
  • Improve soil structure
  • Maintain healthy pH levels
  • Reduce stress in root zones
  • Create healthier plant root environment
  • Produce healthier flower heads and bigger food crops
  • Easier work environment for gardener
  • Improve water holding capacity of soil
  • Conserve water
  • Reduce water runoff
  • Suppress weeds
  • Eliminate use of pesticides and fertilizers

Conveyor Systems for Waste Management

  By | | , , ,

Conveyor systems are an integral component of waste management and recycling operations. It works for various types of materials and transports them to different locations.  They play a vital role in the process of sorting waste material and their movements.  Mixed wastes are arranged for inspection over a conveyor, which then moves it from one end to another. While on its way items are sorted and unwanted materials are removed.

Conveyors are also used for carrying recycling materials such as wood or paper wastes to their respective grinding and process centers. Waste conveyors are manufactured with materials that do not get damaged by constant exposure to abrasives. They are also not affected by sticky or greasy liquids and dirt. Belt conveyors and chain conveyors are the most commonly used conveyors in recycling plants.

material-recovery-facility

Mostly non-powered conveyors are used in the industry. However, powered belt and roller conveyors are sometimes used for handling small products. They are typically used for pallet handling.

Conveyors are also used for moving waste materials in long streams so that they can be separated. Vibrating belts are attached which separate materials that require inspection. Waste materials and recycling industry is mostly about dealing with contaminated products and trash. Thus additional cautions are considered for the safety and environmental standards of the workers.

Types of Conveyors

Conveyors vary in shapes and dimensions according to their utility. From being installed in biomass plants, waste sorting plants, material recovery facilities, waste-to-energy plants, to being a prime component at food processing facilities, paper industry, mining, and pharmaceutics, conveyors are used everywhere.

Even at tough job-sites where transfer of materials is required across steep inclinations or large distances conveyors can ease the process. Generally, they are classified as belt conveyors and screw conveyors.

Waste_Conveyor

Screw Conveyors

Screw conveyors were invented by Archimedes and its core design hasn’t changed from its original design over these years. They can be vertical or horizontal with an entirely contained, metered space. Screw conveyors are generally used for moving dust-free movement of grains or flakes, powders, sludge, etc. They are made of galvanized metal, carbon steel, stainless steel, tapered screws, discharge chute, or in-feed hoppers.

Belt Conveyors

Belt conveyors have a wide-open frame which enables them to contain and move high loads of material over long distances. This is why they are commonly used in the mining industry and other places where heavy materials are required to be transported.  Structurally they are rugged loops that run over two or more pulleys. Additional rolls are also added in between to provide support in long belts.

Materials ranging from garbage to fine grains and powders and be carried over belt conveyors. They are also used for the movement of commercial waste including paper, plastic, or aluminum cans.

Belt material, configuration, and dimension differ according to its application. Various designs of belts are used nowadays, for example, magnetic belts, flat belts, trough belts, rubber belts, etc. Moreover, conveyors are also designed in shapes such as to carry fluids including sludge and water. Key manufacturing materials for these belts are cotton, canvas, leather, nylon, polyester, silicone, and steel. Dimension, design and materials can be easily customized depending on its application and to meet customer requirements.

5 Things You Need to Know About Making Biodiesel at Home

  By | | , , ,
8 Comments

Biodiesel, a petroleum-based diesel alternative produced by transesterification, works as efficiently as the commercially sold diesel and hardly requires any changes in the engine. For those who don’t know, biodiesel can be produced using any oil derived from plants such as soybean oil, cottonseed oil, canola oil, etc. or from animal fats, like beef tallow and chicken tallow.

Over the past five years, due to the spike in fuel prices, people have started moving towards energy independence and have started small private biodiesel production units. According to reports, biodiesel made from useless tires could solve fuel security problems. Tires are a big problem as they create a lot of waste. We can turn this waste into useful oil and help not only the environment but also the economy.

If you are new to biodiesel production, some of the crucial things to know are:

1. Safety

This should not come as a surprise, safety rules are necessary to avoid the contamination of soil and water resources, fires, and personal poisoning.

Vegetable oil to biodiesel conversion requires methanol and lye. Both these chemicals are extremely dangerous since they are not only inflammable but can also cause neurological damage in case of excessive exposure.

A number of biodiesel related accidents and fires have been reported over the last few years. The incidents were a result of pure neglect. Some of the safety measures you should never forget to take are:

  • Don’t process inside your house.
  • Don’t keep any oily rags in the vicinity, they are the main source of spontaneous combustion leading to huge fires.
  • Don’t use paint stirrers or drills to mix up the biodiesel. It can cause a fire.
  • Don’t use blenders to make test batches, the ingredients can react with rubber seals.

All hazardous and dangerous products should be kept in an approved metal fire cabinet when not in use.

2. Environmental Regulations and Feedstock Collection

Currently, non-commercial and small-scale biodiesel production areas are not subjected to regulations by the Department of Environmental Protection (PADEP). However, if complaints or problems arise due to your biodiesel product, your plant might be subjected to discretionary enforcement. Moreover, you’ll need approval if you wish to increase the size of the production unit.

The disposal of by-products, on the other hand, requires the approval of the PADEP and should be done based on the latest guidelines. These guidelines can be obtained from your local Department of Environmental Protection.

Apart from following the rules and regulations, the availability of feedstock is crucial for the process.

One gallon of biodiesel requires at least one gallon of feedstock oil. To reduce production costs and to prevent food for fuel conflict, using inedible oils as a major source for biodiesel production is advised.

Usually, feedstock and feedstock oil are difficult to obtain, hence pre-planning is the key to produce the required amount of biodiesel on a regular basis. The collection and transportation of feedstock including used cooking oils are regulated by PADEP.

3. Time Commitment and Cost Requirements

New users usually underestimate the time requirements for proper and regular biodiesel production. While planning your biodiesel plant, make sure you allocate enough time to maintaining the equipment since improper maintenance lead to accidents. Feedstock collection and fuel processing also require a lot of time.

Other time-consuming tasks include handling and securing chemicals, air drying and water washing the fuel, testing the duel quality, and disposing of by-products.

Even though the cost requirements per gallon of biodiesel fuel process are much lower than the commercially sold diesel, there are a few things you need to take into consideration beforehand.

A detailed analysis of input costs versus the resultant value of fuel produced needs to be performed. The analysis should also include labor costs.

Investment in equipment and facility, feedstock transport and acquisition, chemicals, energy used and by-product disposal costs need to be accounted for as well.

4. Handling and Disposing By-products

During the production process, a considerable amount of crude glycerol is produced. Other processors that use water for biodiesel purification produced two gallons of waste for every gallon of biodiesel.

Handling this amount of waste can be taxing. It needs to be compliant with the PADEP rules and regulations. This not only requires more time but capital as well.

The crude glycerol by-product has 25 percent methanol as well as some hazardous waste. Converting it into marketable glycerin is not feasible on a small-scale since the evaporation of methanol cannot be contained.

The land application of methanol and glycerol are prohibited by PADEP. The disposal options from crude glycerol including methanol are:

  • Disposing of in a landfill.
  • Anaerobic digestion.
  • Industrial combustion.

You have to get special permission from PADEP for all the above processes.

5. Fuel Quality and Storage

Commercial testing of the fuel quality can rip you off since one batch can cost anything between $1000 and $1500. However, simpler fuel testing techniques like sediment testing, methanol testing, water content, viscosity, and cloud point testing can help you find a rough estimate of how good or bad the fuel is. These tests can also help you in finding what needs to be improved during the production process.

To store the fuel, use proper, biodiesel approved and rubber free containers. Using in-line filters while pumping the fuel in storage containers is the best practice. Usually, biodiesel produces use of 10-micron water-blocking filter or a 1-micron filter.

Petroleum approved containers also work well for storing biodiesel. Once in containers, the fuel should be kept in a dry, clean, and dark environment.

If you plan on storing the fuel for a longer time, using algaecide or fungicide additive is recommended since biodiesel is an organic liquid. Also, during cold seasons, the fuel gels, hence, blending in petroleum or anti-gelling additive is pretty important.

For best engine performance, you must use it within six months. If you can, limit the storage time to 3 months in warm and humid weather since the fuel can develop algae or fungus.

A career in waste recycling can not only be profitable but can seriously do some good to the earth’s environment. It’s not a surprise to most people that our environment is deteriorating. The majority of the largest companies have not opted out to use alternative resources that are less destructive to the planet. That’s why a career in waste recycling, particularly plastics recycling, is very rewarding because you take care of not only yourself but also our environment.

Recently, scientists have even rallied to protest their findings of environmental catastrophes that for the most part have been shushed by large conglomerates. The environment needs our help, and a career in recycling can genuinely kill two birds with one stone.

How to Start a Career in Waste Recycling

On that note, any professional needs a bot-beating resume that can pass applicant tracking systems and weed out any other competing applications in the job market. Job seekers who are interested in investing in a top online resume writing service will find what they’re seeking online. Acceptance from a recruiter is a step away

Moving on, here’s a solid guide on starting out in the recycling field:

1. Choose Which Material To Recycle

For those who want to jump-start a career in recycling, then they need to start with the first step. Think about which material your career/business will be recycling. There are many options to consider, and researching the profitability and usefulness of the material will be key driving factors for your career to succeed. Here are some examples:

  • Aluminum Cans
  • Paper
  • Plastics
  • Textiles
  • Glass
  • Electronics
  • Cardboard

Find out which material in your proximity is easily found, or stick to a choice and expand on it. A good factor to always consider is whether the recyclable material is profitable or not.

 

On a side note, professionals jumpstarting any career always need a CV at their disposal. Skillhub can help you connect with a career advice expert if you’ve ever wondered, “Can anyone help me write my cv?” since we know it can be overwhelming to take care of everything.

Moving on, it’s not as if professionals aren’t allowed to recycle more than one material. If that’s the goal then it’s possible but it will prove more complicated than sticking to one material.

2. Executing A Market Survey

Growth and success in a career field require devotion to understanding it. By conducting a market survey, professionals can collect data for the present and the future of their company. They need to do this in order to avoid unnecessary failure and gain beneficial experience.

If your dream job is to be a successful waste recycling business, then don’t skip this step. Apply yourself to the career, and through time and effort, results can be found.

A market survey is essentially the research and analysis of the market of a specific field/product. The research, of course, includes customer preferences. Market surveys can let businesses find out the buying potential of products, and so on.

3. Identify, Extract, Strategize

Now it’s time to identify a niche in your market, extract it, and strategize from there (business plan). Individuals can shine through the art of business creation, so if a career in a business such as waste recycling is your forte, it will start showing by this stage.

A successful career in waste recycling can be achieved through the identification of a certain niche in the market that needs to be filled. Once that niche is identified, the professional can extract it and start strategizing.

For example, viral influencers and business owners Ms. Trautman and Mr. Max Steitz founded their company ‘A Glass Half Full’ in college. They went viral thanks to their documentation of their business and idea, and now they’re using recycled glass to turn it into fake sand. They want to combat coast erosion, but this also gives them an opportunity to sell fake sand to businesses that need it.

In fact, sand is a commodity with such a high demand that it caused ’Sand Wars’ where companies were fighting to own sand that was to be exported. If you don’t believe us, just search up ‘Sand Wars’ on any search engine and read up on this ridiculous story.

4. Acquire Capital

Depending on your own financial status, capital will be needed to get the resources, equipment, and money to pay employees. Your duties as a business owner will be to acquire enough capital so that the waste recycling business will stay afloat and expand.

Of course, not everybody has the money to just start a business like that. For the most part, we’re all living on a very limited monthly salary, so acquiring capital will need you to be resourceful. Here are some ideas on where small business owners can get capital:

  • Bank loans
  • Business And Industry Guaranteed Loan Program
  • Startup companies can take advantage of ‘The Small Business Administration’ for capital resources in the US.
  • The Sustainable Jobs Fund
  • Environmental Protection Agency
  • State loans, grants, and subsidies

5. Take Care Of Legal Obligations

A career in any field requires the tackling of tedious tasks such as legal obligations and dogmatic bureaucracy. It is what it is, and although this might be one of the most tedious parts, it is a necessary evil. So, take care of the demands in this area to avoid any nasty surprises. Here are some pivotal points to take care of:

  • Choosing a business structure
  • Registering with the IRS
  • Getting a business license or permit

Get counsel from a lawyer friend who knows the specific field of law pertaining to business to help clear any confusion, but at some point, most professionals will probably have to consult and pay a good lawyer to help them progress.

6. Finding The Workspace

This is pretty self-explanatory. By this point, we congratulate you on your progress. It’s time to hunt down the recycling space to rent/buy it. Remember, recycling equipment needs a pretty big operational area, so a big workspace in an isolated area would be optimal. You don’t want to bother any people living nearby with noise.
