How Many Main Components are in Integrated Waste Management

Introduction

There has been disagreement on how to handle solid municipal waste for a long time. Some people think waste management, which is the process of controlling newly generated waste and implementing environmentally friendly disposal techniques, is the solution. The second strategy is trash reduction, which entails both cutting back on overall garbage production and figuring out new ways to repurpose waste. Which do you believe to be more crucial, waste management or trash reduction?

There is a new waste management approach that blends the two conflicting systems, even though there are many people with strong ideas about which is preferable. The method, known as integrated waste management, incorporates several types of waste management and waste prevention strategies. Mass-burn incinerators and sanitary landfills are two methods of integrated waste management.

Reusing, recycling, and composting are a few examples of waste reduction techniques that can be a part of integrated waste management. According to economists and scientists, if integrated waste management is widely adopted in the United States, between 75 and 90% of municipal solid trash may be reduced due to the range of solutions put in place.

Integrated waste management is a technology or concept developed to reduce waste to counter the effect of pollution and reduce its impact on the environment.

Integrated Waste Management Priorities

Implementing integrated waste management by utilizing a variety of waste solutions may seem straightforward, but it is more difficult. Three priorities make up the United States Academy of Science's approach to adopting integrated waste management.

This objective's main objective is to reduce pollution and waste by requiring businesses to provide goods with longer shelf life, use less packaging, and make them easier to recycle, reuse, and repair. This initial objective is on large corporations and attempts to reduce overall waste creation at the source.

The secondary prevention of waste and pollution is the second priority, and it targets small businesses and individuals. The goal of this phase is to inform and motivate the general population to buy reusable items, repair damage, recycle, reuse, and compost.

The third priority is significantly different from the first two because it only deals with waste management. This includes processing waste to lessen toxicity, burying or burning waste, and releasing some waste into the environment for dispersal or dilution.

As you can see from the integrated waste management system's priorities, waste reduction requires more attention and effort if the system is to function well. Unfortunately, even though the priorities were created by scientists and supported by facts, most nations, including the United States, still tend to give waste management more emphasis.

Type of waste

Non-biodegradable waste

Biodegradable waste

Biodegradable waste

Any organic material in the garbage that may be broken down by microorganisms and other living things through composting, aerobic digestion, anaerobic digestion, or similar processes into carbon dioxide, water, methane, or simple organic molecules is considered biodegradable waste. The main ingredients are kitchen trash as well as ash, dirt, dung, and other plant stuff (waste food, scraps, and inedible bits). Additionally, some inorganic elements that can be broken down by microbes are included in waste management. These materials include gypsum and its by-products, such as plasterboard, as well as other simple sulfates that, under anaerobic landfill conditions, can be broken down by sulfate-reducing bacteria to produce hydrogen sulfide.

The range of biodegradable trash in a home waste collection may be reduced to only those degradable wastes that could be managed locally.

The definition of biodegradable trash in the home waste collection may be limited to only those degradable wastes that can be processed in the nearby waste management facilities.

When handled improperly, biodegradable trash can significantly contribute to climate change, particularly through methane emissions from anaerobic fermentation that results in landfill gas. Other strategies for lessening the impact include generating less waste, such as by minimizing food waste.

Non-Biodegradable waste

Any type of substance that contributes to pollution and cannot be broken down by living things is considered a non-biodegradable material.

Wastes that are not biodegradable cannot be managed as easily as biodegradable garbage. Non-biodegradable wastes cannot be broken down or removed by natural processes. They remain intact on earth for a very long period. As a result, they present a far greater threat Plastics are a noteworthy example because they are materials that are utilized often in almost every industry. These polymers are given a long-lasting effect through the use of better-quality plastics. They improved in durability and temperature resistance as a result of their use. Additional examples include containers, steel, and compounds used in manufacturing and agriculture. It is they who are primary contributors to diseases including cancer and contamination of the air, water, and soil.

Non-biodegradable wastes must be replaced because they are not environmentally friendly. Scientists have developed a variety of alternatives, including biodegradable polymers and other materials. They added a few biodegradable components to plastics to make them quickly and easily degradable. But this surgery is rather pricey.

Components of integrated west management

Although there are many assumptions about the components of waste management. We are going to talk about the following components source reduction, recycling and compositing, waste transportation and landfalling.

Source reduction

Reduced waste creation is the goal of source reduction, commonly referred to as waste prevention. Source reduction methods can take many different forms, like designing things for recycling and reusing, repairing products to extend their lives, or redesigning products to use less or no packaging.

Recycling and composting

Phases in the Integrated waste management process that are crucial are recycling and composting. Recycling entails gathering, sorting, and recovering materials that are recyclable and reusable as well as reprocessing recyclables to create new goods. The build-up of organic waste and its transformation into soil amendments is known as composting, which is a part of organics recycling. In addition to removing materials from the waste stream to produce affordable sources of material for subsequent use, recycling and composting wastes both have a variety of economic advantages. Composting and recycling both make considerable contributions to lowering greenhouse gas emissions.

The network of decentralized waste-to-energy generating plants reduces the need to move waste over great distances. It makes it possible to generate electricity for residents and businesses using local garbage. Additionally, it provides significant reductions in grid losses, GHG emissions, and transportation costs. In a case study about decentralized W2E power generation that we've created, we go into further detail about how the decentralised model results in significant savings of up to several million euros annually.

The pre-sorting facility separates solid waste streams for straightforward recycling to conserve virgin raw materials, the production of compost or biogas from biodegradable waste, and the use of energy from the remaining waste fractions. The method reduces waste going to landfills and encourages the development of SMEs to use recyclables.

Waste transportation

Another waste management activity that needs to be systematically integrated with others is waste transportation. This will help to ensure effective and seamless waste management. Usually, this involves picking up trash from businesses and the curbside as well as from transfer stations, where the trash can be consolidated and put into other vehicles to be sent to landfills.

Waste disposal

The actions performed to handle non-recyclable garbage include waste disposal, specifically using landfills and combustion. Landfills are the most popular method of managing these wastes, but they need to be carefully planned, built, and maintained.

An unrivalled substitute for landfilling is the use of waste streams in the production of electricity. The Ecosystem, which combines all the various waste-to-value technologies, gets the most energy possible out of the garbage while leaving less than 5% of the initial waste volume for landfilling.

All of the solutions are modular and quickly adapt to changes in trash generation, whether those changes be increases in waste creation due to population and economic expansion or decreases due to improved source sorting and recycling. They provide various degrees of flexibility in terms of electricity generation, operations, and the creation of new businesses.

Integrated waste management example

Integrated waste management is intended, but there are actions you may take as an individual to assist the system. You can organise your kitchen so that it is feasible to classify your garbage according to the relevant categories. You might set aside a container just for recyclables to help with trash reduction. While all recyclables can be disposed of in one container in certain cities, they must first be separated into glass, metals, paper, and plastic in others. Another option for waste reduction is to set up a compost bin where you can gather food scraps for composting. You can use separate bins to dispose of disagreeable and non-disagreeable waste to separate them.

Summary

Although waste management is a problem that has existed since the dawn of civilization, the idea of integrated waste management (IWM) has only recently come into existence. IWM systems create a functional waste management system by combining waste streams, waste collection, treatment, and disposal techniques. Each system can be region-specific and combine the right combination of waste treatment methods to lessen environmental impacts generally in a way that is both economically feasible and socially acceptable. The degree of integration and the specific combination of waste treatment techniques used in any IWM system will depend on the local conditions at the time. This adaptability supports process development, the pursuit of best practices, and solution customization, all of which are required to account for changes in the quantity and quality of the waste stream.
