A combination of high fuel prices and a search for alternative technologies, combined with massive waste generation has led to countries in the Middle East region to consider Waste to Energy (or WtE) as a sustainable waste management strategy and cost-effective fuel source for the future. We look at the current state of the WtE market in the Middle East.

It is estimated that each person in the United Arab Emirates produces 2 kg of municipal solid waste per day – that puts the total waste production figure somewhere in the region of 150 million tonnes every year. Given that the population currently stands at over 9.4 million (2013) and is projected to see an annual average growth figure of 2.3% over the next six years, over three times the global average, it’s clear that this is a lot of waste to be disposed of.

In addition, the GCC nations in general rank in the bottom 10% of the sustainable nations in the world and are also amongst the top per capita carbon-releasers.

When we also consider that UAE are actively pursuing alternative energy technologies to supplement rapidly-decreasing and increasingly-costly traditional fossil fuels, mitigate the harmful effects of landfill, and reduce an ever-increasing carbon footprint, it becomes apparent that high on their list of proposed solutions is Waste to Energy (WtE). It could be an ideal solution to the problem.

What is WtE

Waste-to-Energy works on the simple principle of taking waste and turning it into a form of energy. This can be electricity, heat or transport fuels, and can be achieved in a variety of ways – the most common of which is incineration. MSW is taken to a WtE plant, incinerated at high temperatures and the resultant heat is used to boil water which creates steam to turn turbines, in the same way that burning gas or coal produces power. Gasification and anaerobic digestion are two further WtE methods which are also used.

However, WtE has several advantages over burning fossil fuels. Primarily amongst them are the potential to minimise landfill sites which have caused serious concern for many years. They are not only unsightly, but can also be contaminated, biologically or chemically. Toxic waste can leach into the ground beneath them and enter the water table.

Landfill sites also continuously emit carbon dioxide and methane, both harmful greenhouse gases – in addition methane is potentially explosive. Sending MSW to landfill also discourages recycling and necessitates more demand for raw materials. Finally, landfill sites are unpleasant places which attract vermin and flies and give off offensive odours.

Waste to Energy Around the World

WtE has been used successfully in many countries around the world for a long time now. Europe is the most enthusiastic proponent of WtE, with around 450 facilities; the Asia-Pacific region has just over 300; the USA has almost 100. In the rest of the world there are less than 30 facilities but this number is growing. Globally, it is estimated that the WtE industry is growing at approximately US $2 billion per annum and will be valued at around US $80 billion by the year 2022.

Waste-to-Energy is now widely accepted as a part of sustainable waste management strategy.

The USA ranks third in the world for the percentage of waste which is incinerated for energy production. Around 16% of the rubbish that America produces every day is burned in its WtE plants. Advocates claims the advantages are clear:

  • reducing the amount of greenhouse gas emitted into the environment (estimates say that burning one ton of waste in a WtE plant saves between one half and one ton of greenhouse gases compared to landfill emissions, or the burning of conventional fuels),
  • freeing up land which would normally be used for landfill (and, therefore, extending the life of existing landfill sites),
  • encouraging recycling (some facilities have managed to reduce the amount of waste they process by up to 90% and the recycling of ferrous and non-ferrous metals provides an additional income source), and,
  • most importantly, producing a revenue stream from the sale of the electricity generated.

In one small county alone, Lancaster, Pennsylvania, with a population of just over half-a-million people, more than 4.4 billion kWh of electricity has been produced through WtE in the last 20 years. This has generated over USD $256 million through its sale to local residents.

Waste-to-Energy in the Middle East

Given WtE’s potential to not only reduce greenhouse gas emissions and pollution on a local scale, but also to produce much-needed electricity in the region, what is the current state of affairs in the Middle East. There are several WtE initiatives already underway in the Middle East.

Qatar was the first GCC country to implement a waste-to-energy programme and currently generates over 30MW of electricity from its Domestic Solid Waste Management Center (DSWMC) located at Messeid (Doha). Saudi Arabia and the UAE have both stated that they have WtE production capacity targets of 100MW. Bahrain, Kuwait and Oman are also seriously considering waste-to-energy as a means to tackle the worsening waste management problem.

Abu Dhabi’s government is currently spending around US $850 million to build a 100 MW plant which will supply around 20,000 households with electricity. In Sharjah, the world’s largest household waste gasification plant, costing in excess of US $480 million, is due to be open soon.

However, not all the GCC members are as enthusiastic about WtE. Dubai’s government has recently scrapped plans for a US $2 billion project which would have made use of the 7,800 tonnes of domestic waste which is produced in Dubai every single day.

We asked Salman Zafar, Founder of Doha-based EcoMENA, a popular sustainability advocacy, why given the sheer scale of the waste in the Gulf region, the production of this form of energy is still in its infancy. “The main deterrent in the implementation of WtE projects in the Middle East is the current availability of cheap sources of energy already available, especially in the GCC,” he commented.

Salman Zafar further says, “WtE projects demand a good deal of investment, heavy government subsidies, tipping fees, power purchase agreements etc, which are hard to obtain for such projects in the region.” “The absence of a sustainable waste management strategy in Middle East nations is also a vital factor behind the very slow pace of growth of the WtE sector in the region. Regional governments, municipalities and local SWM companies find it easier and cost-effective to dump untreated municipal waste in landfills,” he added.

So, how can WtE contribute towards the region’s growing power demand in the future?

“Modern WtE technologies, such as RDF-based incineration, gasification, pyrolysis, anaerobic digestion etc, all have the ability to transform power demand as well as the waste management scenario in the region,” he continued. “A typical 250 – 300 tons per day WtE plant can produce around 3 – 4 MW of electricity and a network of such plants in cities across the region can make a real difference in the energy sector as well as augmenting energy reserves in the Middle East. In fact, WtE plants also produce a tremendous about of heat energy which can be utilised in process industries, further maximising their usefulness,” Salman Zafar concluded.

New technologies naturally take time to become established as their efficiency versus cost ratios are analysed. However, it is becoming increasingly clearer that waste-to-energy is a viable and efficient method for solid waste management and generation of alternative energy in the Middle East.

In an era marked by environmental awareness, crafting an effective waste recycling strategy is essential for individuals, communities, and businesses alike. Adopting sustainable practices not only reduces the strain on landfills but also contributes to the conservation of earth’s precious resources. This article presents five crucial tips that can pave the way for a successful waste recycling strategy, promoting a greener future for the planet.

Four recycle bins of different colors

To transition to a zero-waste lifestyle, you should always recycle.

1. Source Segregation: Streamlining the Recycling Process

At the heart of any recycling strategy lies source segregation, the practice of sorting waste materials at the point of disposal. By categorizing waste into distinct streams, such as paper, plastics, glass, and organic matter, you streamline the recycling process and ensure that each material is processed optimally. This step minimizes contamination and maximizes the value derived from recycled materials, making it a cornerstone of an effective waste management plan.

2. Public Awareness and Education: Fostering a Recycling Culture

Raising public awareness is pivotal in driving successful waste recycling. Communities and businesses must invest in educational campaigns to inform individuals about the importance of recycling and proper disposal techniques. Collaborating with schools and local organizations can amplify these efforts. By emphasizing the tangible benefits of recycling and illustrating how small actions can collectively make a significant impact, a recycling culture can flourish.

3. Technology Integration: Enhancing Efficiency and Monitoring

Incorporating technology into waste-recycling strategies can yield impressive results. Smart bins equipped with sensors can monitor fill levels, optimizing waste collection routes and reducing unnecessary pickups. Additionally, data-driven insights can aid in fine-tuning recycling programs over time. A partnership with an electricity provider can help power these technological advancements sustainably, ensuring that monitoring systems are efficient and environmentally friendly.

This proactive engagement with industry leaders further solidifies the waste recycling strategy’s impact, driving positive change across sectors and inspiring a broader shift toward a circular, waste-conscious economy.

5. Continuous Evaluation and Adaptation: A Dynamic Approach

A successful waste recycling strategy isn’t static; it evolves over time. Regular evaluation of the program’s effectiveness is vital. Metrics such as waste diversion rates, reductions in contamination, and resource savings should guide refinements to the strategy. Stakeholder feedback can provide valuable insights for adapting the strategy to changing needs and advancements. This dynamic approach ensures that the strategy remains effective in addressing the evolving landscape of waste management challenges and opportunities.

Bottom Line

Crafting and implementing an effective waste recycling strategy demands commitment, collaboration, and innovation. By embracing source segregation, raising awareness, leveraging technology, fostering circular economy partnerships, and maintaining adaptability, communities and businesses can pave the way for a greener, more sustainable future. Each step taken toward waste recycling is a step toward preserving the planet’s resources for generations to come.

Biogas from Slaughterhouse Wastes

Slaughterhouse waste (or abattoir waste) disposal has been a major environmental challenge in all parts of the world. The chemical properties of slaughterhouse wastes are similar to that of municipal sewage, however the former is highly concentrated wastewater with 45% soluble and 55% suspended organic composition. Blood has a very high COD of around 375,000 mg/L and is one of the major dissolved pollutants in slaughterhouse wastewater.

slaughterhouse-waste

In most of the developing countries, there is no organized strategy for disposal of solid as well as liquid wastes generated in abattoirs. The solid slaughterhouse waste is collected and dumped in landfills or open areas while the liquid waste is sent to municipal sewerage system or water bodies, thus endangering public health as well as terrestrial and aquatic life. Wastewater from slaughterhouses is known to cause an increase in the BOD, COD, total solids, pH, temperature and turbidity, and may even cause deoxygenation of water bodies.

Anaerobic Digestion of Slaughterhouse Wastes

There are several methods for beneficial use of slaughterhouse wastes including biogas generation, fertilizer production and utilization as animal feed. Anaerobic digestion is one of the best options for slaughterhouse waste management which will lead to production of energy-rich biogas, reduction in GHGs emissions and effective pollution control in abattoirs.

Anaerobic digestion can achieve a high degree of COD and BOD removal from slaughterhouse effluent at a significantly lower cost than comparable aerobic systems. The biogas potential of slaughterhouse waste is higher than animal manure, and reported to be in the range of 120-160 m3 biogas per ton of wastes. However the C:N ratio of slaughterhouse waste is quite low (4:1) which demands its co-digestion with high C:N substrates like animal manure, food waste, crop residues, poultry litter etc.

Slaughterhouse effluent has high COD, high BOD, and high moisture content which make it well-suited to anaerobic digestion process. Slaughterhouse wastewater also contains high concentrations of suspended organic solids including pieces of fat, grease, hair, feathers, manure, grit, and undigested feed which will contribute the slowly biodegradable of organic matter. Amongst anaerobic treatment processes, the up-flow anaerobic sludge blanket (UASB) process is widely used in developing countries for biogas production from abattoir wastes.

Slaughterhouse waste is a protein-rich substrate and may result in sulfide formation during anaerobic degradation. The increased concentration of sulfides in the digester can lead to higher concentrations of hydrogen sulfide in the biogas which may inhibit methanogens. In addition to sulfides, ammonia is also formed during the anaerobic digestion process which may increase the pH in the digester (>8.0) which can be growth limiting for some VFA-consuming methanogens.

Concept of Zero Waste and Role of MRFs

Communities across the world are grappling with waste management issues. A consensus is emerging worldwide that the ultimate way to deal with waste is to eliminate it. The concept of Zero Waste encourages redesign of resource life cycles so that all products are reused, thereby systematically avoiding and eliminating the volume and toxicity of waste and materials.

zero-waste-MRF

The philosophy of Zero Waste strives to ensure that products are designed to be repaired, refurbished, re-manufactured and generally reused. Among key zero waste facilities are material recovery facilities, composting plants, reuse facilities, wastewater/biosolids plants etc.

Material recovery facilities (MRFs) are an essential part of a zero waste management program as it receives separates and prepares recyclable materials for marketing to end-user manufacturers. The main function of the MRF is to maximize the quantity of recyclables processed, while producing materials that will generate the highest possible revenues in the market. MRFs can also process wastes into a feedstock for biological conversion through composting and anaerobic digestion.

A materials recovery facility accepts materials, whether source separated or mixed, and separates, processes and stores them for later use as raw materials for remanufacturing and reprocessing. MRFs serve as an intermediate processing step between the collection of recyclable materials from waste generators and the sale of recyclable materials to markets for use in making new products.

There are basically four components of a typical MRF: sorting, processing, storage, and load-out. Any facility design plan should accommodate all these activities which promote efficient and effective operation of a recycling program. MRFs may be publicly owned and operated, publicly owned and privately operated, or privately owned and operated.

There are two types of MRFs – dirty and clean. A dirty MRF receives mixed waste material that requires labor intense sorting activities to separate recyclables from the mixed wastes. A clean MRF accepts recyclable materials that have already been separated from the components in municipal solid waste (MSW) that are not recyclable. A clean MRF reduces the potential for material contamination.

A typical Zero Waste MRF (ZWMRF) may include three-stream waste collection infrastructure, resource recovery center, reuse/recycling, residual waste management facility and education centers.

The primary objective of all MRFs is to produce clean and pure recyclable materials so as to ensure that the commodities produced are marketable and fetch the maximum price. Since waste streams vary in composition and volume from one place to another, a MRF should be designed specifically to meet the short and long term waste management goals of that location. The real challenge for any MRF is to devise a recycling strategy whereby no residual waste stream is left behind.

The basic equipment used in MRFs are conveyors & material handling equipment to move material through the system, screening equipment to sort material by size, magnetic separation to remove ferrous metals, eddy current separation to remove non-ferrous metals, air classifiers to sort materials by density, optical sorting equipment to separate plastics or glass by material composition, and baling equipment to prepare recovered material for market. Other specialized equipment such as bag breakers, shredders and sink-float tanks can also be specified as required by application.

The Energy Potential of Palm Kernel Shells

The Palm Oil industry in Southeast Asia and Africa generates large quantity of biomass wastes whose disposal is a challenging task. Palm kernel shells (or PKS) are the shell fractions left after the nut has been removed after crushing in the Palm Oil mill. Kernel shells are a fibrous material and can be easily handled in bulk directly from the product line to the end use. Large and small shell fractions are mixed with dust-like fractions and small fibres. Moisture content in kernel shells is low compared to other biomass residues with different sources suggesting values between 11% and 13%.

palm-kernel-shells

Palm kernel shells contain residues of Palm Oil, which accounts for its slightly higher heating value than average lignocellulosic biomass. Compared to other residues from the industry, it is a good quality biomass fuel with uniform size distribution, easy handling, easy crushing, and limited biological activity due to low moisture content. PKS can be readily co-fired with coal in grate fired -and fluidized bed boilers as well as cement kilns in order to diversify the fuel mix.

The primary use of palm kernel shells is as a boiler fuel supplementing the fibre which is used as primary fuel. In recent years kernel shells are sold as alternative fuel around the world. Besides selling shells in bulk, there are companies that produce fuel briquettes from shells which may include partial carbonisation of the material to improve the combustion characteristics.

As a raw material for fuel briquettes, palm shells are reported to have the same calorific characteristics as coconut shells. The relatively smaller size makes it easier to carbonise for mass production, and its resulting palm shell charcoal can be pressed into a heat efficient biomass briquette.

Palm kernel shells have been traditionally used as solid fuels for steam boilers in palm oil mills across Southeast Asia. The steam generated is used to run turbines for electricity production. These two solid fuels alone are able to generate more than enough energy to meet the energy demands of a palm oil mill. Most palm oil mills in the region are self-sufficient in terms of energy by making use of kernel shells and mesocarp fibers in cogeneration.

In recent years, the demand for palm kernel shells has increased considerably in Europe, Asia-Pacific, China etc. resulting in price close to that of coal. Nowadays, cement industries and power producers are increasingly using palm kernel shells to replace coal. In grate-fired boiler systems, fluidized-bed boiler systems and cement kilns, palm kernel shells are an excellent fuel.

Cofiring of PKS yields added value for power plants and cement kilns, because the fuel significantly reduces carbon emissions – this added value can be expressed in the form of renewable energy certificates, carbon credits, etc. However, there is a great scope for introduction of high-efficiency cogeneration systems in the industry which will result in substantial supply of excess power to the public grid and supply of surplus PKS to other nations. Palm kernel shell is already extensively in demand domestically by local industries for meeting process heating requirements, thus creating supply shortages in the market.

Palm oil mills around the world may seize an opportunity to supply electricity for its surrounding plantation areas using palm kernel shells, empty fruit branches and palm oil mill effluent which have not been fully exploited yet. This new business will be beneficial for all parties, increase the profitability and sustainability for palm oil industry, reduce greenhouse gas emissions and increase the electrification ratio in surrounding plantation regions.

The Environmental Impact Of Tire Recycling

In a world where sustainability is more critical than ever, recycling has become essential to global discussions around environmental conservation.

One aspect often overlooked in the discourse is tire recycling.

Before 2013, numerous ecological issues arose from incinerating or sending discarded tires to landfills. A report by the Tire Industry Project for the World Business Council for Sustainable Development estimates there are 4 billion end-of-life tires (ELT) in landfills and other stockpiles around the world. Although tire recovery rates have improved over the past decade, they may not be sufficient to handle the additional 1 billion ELTs generated globally each year.

environmental benefits of tire recycling

This article explores the complex issue of tire recycling, its environmental impact, and potential solutions to this waste management challenge.

The Problem With Tire Disposal

Landfilled tires can take hundreds of years to decompose. This can cause several issues, including:

Groundwater and soil pollution

Different materials and chemicals, including rubber, carbon black steel, and various additives, make up tires. Over time, the harsh environmental conditions within landfills can cause these materials to break down and leach into the surrounding soil and groundwater, potentially contaminating drinking water and agricultural land.

Methane emissions

As tires decompose, they release methane gas, which is about 25 times more effective at trapping heat than carbon dioxide. Additionally, methane is highly flammable and can create an explosion hazard if it accumulates in high concentrations, posing environmental and safety risks.

Health hazards

Tires can catch fire easily due to their high heat retention and flammability. Tire fires are notoriously difficult to extinguish, often burning for days or weeks. They also generate a significant amount of toxic smoke, including pollutants like dioxins and furans, that can cause serious health problems in humans and animals.

scrap-tires-pyrolysis

Fortunately, the modern tire recycling machine has become an effective tool for alleviating these problems, with equipment manufacturers making them more accessible. These machines help mitigate the environmental issues and hazards mentioned above by recovering materials from tire waste, such as steel, fiber, and rubber, to produce various raw materials.

You can get a closer look at these amazing machines here: https://www.youtube.com/@gradeallinternationalltd1012/videos

Beneficial Tire Recycling Methods

Given the abovementioned issues, tire recycling ought to become an increasingly critical aspect of waste management.

Modern tire recycling machines and methods have been developed to repurpose old tires into usable raw materials, which conserves valuable resources and reduces environmental harm. These methods include:

Ambient shredding

In this process, powerful, interlocking knives cut tires into smaller pieces. Professionals can further separate these pieces into different components, such as ‘crumb rubber,’ which has various applications. For example, manufacturers often use it as a raw material in playground surfaces and sports fields. Additionally, road construction projects use crumb rubber as an additive for asphalt, creating rubberized roads that last longer and reduce road noise.

Cryogenic grinding

This method freezes tires using liquid nitrogen or compressed air. Once the tires become brittle, they can be easily shattered into small pieces, producing clean, high-quality rubber powder. This material has myriad applications, usually used in making new tires, automotive parts, and substances like sealants, coatings, and adhesives.

Pyrolysis

This method involves heating tires in an oxygen-free chamber, which decomposes the tires into oil, gas, and carbon black. Pyrolytic oil can substitute conventional fuels in industrial applications, while the resultant gas can generate electricity. For its part, carbon black can be repurposed for producing new tires or as a pigment in manufacturing inks, paints, and plastic products.

Each of these methods effectively transforms what would otherwise be a significant environmental issue into valuable materials and energy sources, significantly reducing the carbon footprint of used tires. These practices show how tire recycling isn’t just a potential solution to an environmental problem but an effective way to achieve sustainability.

environmental impact of tire recycling

The Road Ahead

Looking forward, it’s clear that tire recycling on a global scale can contribute to achieving sustainable waste management. The triumvirate of continual advancements in recycling technology, rigorous government regulations, and public awareness campaigns are expected to drive growth in the field.

Moreover, developing sustainable markets for recycled tire products is a crucial factor for the future of tire recycling. Transforming used tires into valuable commodities allows us to resolve a significant waste problem while conserving natural resources and building up a circular economy.   

Recycling Remains Relevant

As the world continues to grapple with the challenges of waste management, tire recycling may be a powerful example of how innovative solutions can transform a significant environmental problem into an opportunity for sustainable development.

The future of tire recycling holds substantial promise for both the environment and the economy, demonstrating how innovative, sustainable solutions can drive progress.

Wastes Generation in Tanneries

Wastes originate from all stages of leather making process, such as fine leather particles, residues from various chemical discharges and reagents from different waste liquors comprising of large pieces of leather cuttings, trimmings and gross shavings, fleshing residues, solid hair debris and remnants of paper bags.

tannery-wastes

Tanning refers to the process by which collagen fibers in a hide react with a chemical agent (tannin, alum or other chemicals). However, the term leather tanning also commonly refers to the entire leather-making process. Hides and skins have the ability to absorb tannic acid and other chemical substances that prevent them from decaying, make them resistant to wetting, and keep them supple and durable. The flesh side of the hide or skin is much thicker and softer. The three types of hides and skins most often used in leather manufacture are from cattle, sheep, and pigs.

Out of 1000 kg of raw hide, nearly 850 kg is generated as solid wastes in leather processing. Only 150 Kg of the raw material is converted in to leather. A typical tannery generate huge amount of waste:

  • Fleshing: 56-60%
  • Chrome shaving, chrome splits and buffing dust: 35-40%
  • Skin trimming: 5-7%
  • Hair: 2-5%

Over 80 per cent of the organic pollution load in BOD terms emanates from the beamhouse (pre-tanning); much of this comes from degraded hide/skin and hair matter. During the tanning process at least 300 kg of chemicals (lime, salt etc.) are added per ton of hides. Excess of non-used salts will appear in the wastewater.

Because of the changing pH, these compounds can precipitate and contribute to the amount of solid waste or suspended solids. Every tanning process step, with the exception of finishing operations, produces wastewater. An average of 35 m3 is produced per ton of raw hide. The wastewater is made up of high concentration of salts, chromium, ammonia, dye and solvent chemicals etc.

A large amount of waste generated by tanneries is discharged in natural water bodies directly or indirectly through two open drains without any treatment. The water in the low lying areas in developing countries, like India and Bangladesh, is polluted in such a degree that it has become unsuitable for public uses. In summer when the rate of decomposition of the waste is higher, serious air pollution is caused in residential areas by producing intolerable obnoxious odours.

Tannery wastewater and solid wastes often find their way into surface water, where toxins are carried downstream and contaminate water used for bathing, cooking, swimming, and irrigation. Chromium waste can also seep into the soil and contaminate groundwater systems that provide drinking water for nearby communities. In addition, contamination in water can build up in aquatic animals, which are a common source of food.

The Top 7 Benefits of Composting

  By | | , , ,
Leave a comment

The impact of human activities on the environment is rapidly changing. One such activity gaining much attention is waste disposal. A lot of waste products go to landfills despite constituting a reasonable fraction of organic matter, such as paper materials, food wastes, and pet droppings.

The new preferred way to dispose of organic waste is composting. Composting refers to the process through which materials biodegrade. It is a means by which organic waste can be safely recycled. Composting can be effectively done with compost systems.

benefits-composting

Take note that this process of waste disposal is still in its early stages, especially when adopted in homes. Still, here are 7 benefits of composting:

1. Improved Soil Quality

Composted materials become humus, a known nutrient-rich constituent of soil. The newly formed humus replenishes soil nutrients and improves water retention in loose soil. Thus, soil quality considerably improves as a result of composting.

Composted materials are also rich in fungi and bacteria. These microbes prevent insect infestation and suppress weed growth. With these nutrient draining agents out of the way, your soil quality dramatically improves, too.

2. Saves Time and Money

It is a waste of time and money when a yard being cultivated does not experience normal growth, nor does it yield the expected harvest. Fortunately, you can save money and time in the long term with composting practices. This is possible because of the compost’s ability to fight insect infestation, weed growth, and to replenish the soil of lost nutrients.

The three nutrients that are sought in chemical fertilizers, Nitrogen, Phosphorus, and Potassium (NPK), are made available by humus. This directly saves you the cost of purchasing fertilizers. Without the presence of compost, farmers need to spend a lot of money to buy pesticides and weed killers.

3. Environment Friendliness

Composting is an environmentally friendly option compared to landfills. Landfills are currently the most common destination for organic waste. In landfills, organic waste cannot decay properly, so they generate a specific greenhouse gas called methane.

landfills-methane-gas

Methane is known to cause harmful effects on the environment – similar to that of carbon dioxide but even more dangerous. The more organic waste ends up in landfills, the more methane gas that is produced.

Composting solves this problem in a whiff by reducing the amount of methane produced while organic matter decays. Composting allows carbon to be retained in the soil, which lowers the carbon footprint caused by decaying matter.

The ability of compost to bypass the incineration of yard waste also makes it a preferred option for organic waste in yards.

4. Improved Human Health

There are several ways for composting to indirectly enhance human health. The reduction of greenhouse gas emissions, as mentioned above, by composting is not only good for the environment but also for people – a reduction of greenhouse gas means a healthier environment to live in.

Organic food production credited to composting also improves human health in significant ways. It reduces the number of chemicals from fertilizers and pesticides that end up in meals, translating to healthier humans.

5. Higher Agricultural Yield

A higher yield of crops is very important to farmers. Through its ability to increase soil quality, composting achieves a higher return in agricultural products. More plant yield accounts for more plants to be sold, which also means more money to be made.

Soil quality also translates to the quality of the food which is produced. Food produced from high-quality, organic soil is free from all toxins from chemical fertilizers and pesticides.

6. Reduced Erosion

Erosion is harmful to the soil because it makes soil matter and nutrients to be washed away. This is compounded by the fact that soils are loose.

Compost averts erosion by remedying the existing structure of the soil. It further prevents erosion by:

  • Aiding water infiltration in the soil structure.
  • Aiding water retention, thereby slowing runoff and loss of soil matter.
  • Allows for quicker vegetation growth.

7. Aids Biodiversity

Microorganisms present in the soil, such as bacteria, fungi, and protozoa, will cause the decay of organic material. Their presence is important because they aid soil aeration. Soil aeration on its own accelerates the composting process, making nutrients available in their usable state as quickly as possible.

Other organisms that are present in composted soil include worms and beneficial insects. All these aids the process of plant growth.

Conclusion

Composting is a sustainable and environmentally friendly way to dispose of organic waste. It is particularly important even now as the world struggles with creating solutions to waste disposal.

The application of compost results in better soil quality. It is also a process that saves them time and money of farmers. Humans can benefit from composting through improved health. There is a higher yield of farm produce as a result of composting. Erosion is significantly reduced, and biodiversity is achieved in the soil through composting.

2. Reduce Waste Production

We’ve all heard that prevention is better than cure. Look at it this way: If your business generates less waste, dealing with waste becomes a lot easier. So, how can you go about this?

Considering that most businesses are embracing technology, you can start by cutting down on your paper usage. Additionally, if your business makes use of battery-operated equipment, you can swap regular batteries for rechargeable ones. You can also come up with waste reduction plans and strategies.

It’s a good idea to monitor your business waste for a certain period and spot areas that provide a scope for waste reduction. You can also get your employees involved in this process.

3.  Follow Protocols

Depending on the industry you’re in, you may have a set of waste management protocols you are required to follow. For instance, if you’re dealing with pharmaceuticals, there’s a lot of medical waste that needs to be taken care of daily.

expired-medicines-management

Pharmaceutical industry can change its practices to manage pharmaceuticals in a more ecofriendly manner.

You need to follow proper incineration, chemical disinfection, dry thermal treatment, microwave irradiation, land disposal, and inertisation processes. Similarly, every industry has a set of protocols to follow.

While the process is bound to be time-consuming, it will help get your large and complex waste sorted once and for all. Improper waste management can create problems for your business in the long run, so it would be best to avoid such a situation.

4. Help Others to Help You

It may be that some of the waste your business generates, like leftover food, materials, and other products, can be donated to vulnerable communities.

5. Tackle the Big Packaging Problem

Packaging can make up a huge proportion of your waste. Every business makes use of packaging in some way or the other. What can you do differently to reduce the packaging you handle?

First, you can adopt a minimalist approach. Don’t use packaging unless a product really needs it. Second, being resourceful can help. For example, it doesn’t make sense to use an entire cardboard crate to pack a product that’s only half the size.

Packaging that adorns your product can have serious environmental impact.

Considering that many packaging materials like bubble wraps are plastic, it’s important not to over-use them. By minimising the materials that go into packaging, you’re directly reducing your business’ packaging-related waste.

A typical home can contain a vast array of household hazardous wastes used for cleaning, painting, beautifying, lubricating and disinfecting the house, yard, workshop and garage. The chemical-based household products from a single home may seem insignificant; but, when millions of homes use similar products, handling, storing and disposing them improperly may have the combined impact and becomes a major problem.

The health and safety of our families, neighborhoods and environment is threatened when household hazardous waste is stored or disposed of improperly. These products should not be put in the garbage bins or disposed in the storm drains or burned, as they pose a threat to human health and the environment. Thousands of consumer products are hazardous. The general categories are:

  • Automotive products: Gasoline, motor oil, antifreeze, windshield wiper fluid, car wax and cleaners, lead-acid batteries, brake fluid, transmission fluid etc.
  • Home improvement products: Paint, varnish, stain, paint thinner, paint stripper, caulk, adhesives etc.
  • Pesticides: Insecticide and insect repellent, weed killer, rat and mouse poison, pet spray and dip, wood preservative etc.
  • Household cleaners: Furniture polish and wax, drain opener, oven cleaner, tub and tile cleaner, toilet bowl cleaner, spot remover, bleach, ammonia etc.
  • Other: Household batteries, cosmetics, pool chemicals, shoe polish, lighter fluid, prescription medicines etc.

Each year, thousands of people are injured by exposure or accident involving hazardous household products.  Because of the dangers they pose. These products require special awareness, handling, and disposal.  In order to protect health and environment, every consumer should know how to properly use, store, and dispose of hazardous household products. 

Many common household products contain hazardous chemicals.  Once released into the environment, these substances may pose a serious threat to living organisms.  Small quantities of hazardous substances can accumulate over time to reach dangerous levels and contaminate the air, water, and soil. 

Here are some basic guidelines for managing household hazardous wastes:

  • Select the least toxic item and buying only the minimum quantity as required.
  • Read the entire label carefully for health warnings and use good judgment when choosing any product.
  • Store the product at a safe place and away from the children reach.
  • Avoid aerosol products.
  • Always use hazardous products in a well-ventilated area.
  • Never leave containers open.  Many products are volatile, evaporating quickly into the air. 
  • Always seal containers tightly after use.
  • Never mix chemicals and hazardous products. 
  • Do not use spent chemical containers for other purposes.
  • Wear protective clothing such as gloves and a mask when dealing with any hazardous material. 
  • Wash clothing exposed to hazardous materials separately from other clothes.
  • Do not eat, drink or smoke while using hazardous products.
  • Clean up the place after using hazardous products. Carefully seal products and properly refasten all caps.
  • Never put hazardous products in food or beverage containers.
  • Keep products away from sources of heat, spark, flame or ignition.
  • Know where flammable materials are located in your home and how to extinguish them.
  • Keep a multi-purpose dry chemical fire extinguisher in your home.
