Waste management basics

What is waste management and recycling?

Waste management and recycling are two crucial practices essential for maintaining a sustainable environment. Waste management refers to the process of collecting, transporting, processing, and disposing of waste materials. Waste management encompasses various activities to reduce, reuse, and recycle waste materials. It involves the proper handling of waste from the point of generation to its final disposal.

Recycling involves the conversion of waste into useful materials or products. This helps reduce the amount of waste ending up in landfills and reduces the need for new raw materials.

Together, waste management and recycling play a significant role in reducing the negative impact of human activities on the environment.

Importance of waste management and recycling for the environment

Waste management and recycling have significant environmental benefits. Proper waste management practices help prevent air, water, and soil pollution. Recycling also reduces the need for landfills and incineration, which can release harmful pollutants into the environment. Additionally, recycling can save energy and reduce carbon emissions associated with the production of new products.

Waste management and recycling also play an essential role in conserving natural resources. By recycling materials such as paper, plastic, and metal, we reduce the need for new raw materials, which can lead to deforestation, mining, and other destructive practices.

The problem of waste

Types of waste and their impact on the environment

Waste comes in many forms, including household waste, industrial waste, hazardous waste, and electronic waste. The disposal of these waste types can have significant impacts on the environment. For instance, household waste, such as plastic bags and food waste, can contribute to polluting water bodies and releasing greenhouse gases into the atmosphere. Industrial waste, on the other hand, can contain harmful chemicals and toxins that seep into soil and water sources, posing a risk to both human and animal health.

Statistics on waste production and disposal

According to the World Bank, global waste production is set to increase by 70% by 2050, with cities being the largest contributors to this trend. Globally, 2.01 billion tonnes of municipal solid waste are generated each year, with at least 33% not managed in an environmentally safe manner and only about 32% of that waste being recycled. 

The United States Municipal Solid Waste Management Market is expected to surpass $25 billion by 2024. The United States spends about $200 billion a year on solid waste management and lost energy resources from trash disposal. Upper-middle- and high-income countries provide nearly universal waste collection. However, lower-income countries collect about 48% of waste in cities, but this proportion drops drastically to 26% outside of urban areas.

East Asia and the Pacific Region produce the highest amount of Municipal Solid Waste (MSW) globally. China, being the most populous country, accounts for over 15% of the world's MSW. Despite having less than 5% of the world's population, the United States is the largest MSW generator globally, producing approximately 12% of the world's MSW and having the highest per capita waste production. 

On average, Americans generate more than 800 kilograms of waste annually per person, more than twice Japan's per capita waste production, where citizens produce around 350 kilograms of MSW annually. Interestingly, Denmark is Europe's top MSW producer per capita, with Danes generating a similar volume of waste as Americans. Urban areas generally produce twice as much waste as rural areas.

The environmental and health risks of improper waste management

Improper waste management practices, such as open dumping and burning of waste, have severe environmental and health consequences. The release of toxic chemicals and pollutants into the air, soil, and water sources can lead to respiratory illnesses, cancers, and other chronic health conditions. Standing waters in waste items favour cholera and vector-borne diseases such as malaria and dengue.

Additionally, these practices can contribute to the destruction of natural habitats, soil erosion, and contamination of water sources. The World Health Organisation (WHO) estimates poor waste collection leads to environmental and marine pollution, like blocking water drains. More than 2 billion tonnes of MSW are produced annually.

Waste reduction and recycling are two key practices that can help achieve a greener future. By reducing waste production and recycling materials, we can conserve natural resources, reduce pollution, and minimise the environmental impact of waste disposal. This can also create economic opportunities and jobs in the recycling and waste-management industries.

Adopting sustainable waste-management practices can have numerous benefits for the environment and human health. Proper waste segregation, collection, and disposal can reduce the release of harmful pollutants and toxins into the environment. Additionally, sustainable waste-management practices can lead to the recovery of valuable resources, reducing the need for new raw materials and conserving natural resources.

Sustainable waste management practices

There are several sustainable waste management practices that can contribute to a greener future. These practices reduce waste production, increase recycling rates, and minimise the environmental impact of waste disposal.

Reduce, Reuse, Recycle: The three R's of sustainable waste management

The three R's—Reduce, Reuse, and Recycle—form the basis of sustainable waste management. By reducing waste production, reusing materials, and recycling materials, we can conserve natural resources, reduce pollution, and minimise waste disposal in landfills.

Composting: turning organic waste into soil conditioner

Composting is a natural process that involves the breakdown of organic waste into nutrient-rich soil conditioner. This practice helps to divert organic waste from landfills, reducing methane emissions and improving soil health. According to the Environmental Protection Agency (EPA), over 63 million tonnes of food waste are generated in the commercial, institutional, and residential sectors annually, with only 4% managed via composting.

Waste-to-energy: using waste as fuel for energy production

Waste-to-energy is the process of generating electricity or heat from municipal solid waste or garbage. This comprises various materials, including biogenic (plant or animal-based) products like paper, cardboard, food waste, grass clippings, leaves, wood, and leather goods. It also includes non-biogenic combustible materials, like plastics and other synthetic materials produced from petroleum, and non-combustible materials, like metals and glass.

Waste-to-energy can help reduce waste volume, minimise the environmental impact of waste disposal, and produce renewable energy. The US Energy Information Agency (EIA) estimated that in 2021, 64 United States power plants generated about 13.6 billion kilowatt hours of electricity from burning about 28 million tonnes of combustible MSW for electricity generation.

Extended Producer Responsibility (EPR) 

Extended Producer Responsibility (EPR) is a policy approach that holds manufacturers responsible for the environmental impact of their products throughout their lifecycle. EPR encourages manufacturers to take responsibility for the entire product lifecycle. This includes designing products that are easy to recycle, providing take-back programmes for end-of-life products, and promoting sustainable production practices.

The Organisation for Economic Co-operation and Development (OECD) characterises an EPR policy by: a) the shifting of responsibility (physically and/or economically; fully or partially) upstream toward the producer and away from municipalities; and b) the provision of incentives to producers to consider environmental considerations when designing their products. While other policy instruments tend to target a single point in the chain, EPR seeks to integrate signals related to the environmental characteristics of products and production processes throughout the product chain.

Zero Waste 

Zero Waste is a holistic approach to waste management that aims to eliminate waste by redesigning systems and processes to minimise waste production and maximise resource recovery. The goal is to create a closed-loop system where resources are conserved, waste is minimised, and products are reused, recycled, or composted.

The Zero Waste approach focuses on reducing the amount of waste produced, reusing products and materials, and recycling or composting the remaining waste. It emphasises the importance of product design and manufacturing practices that minimise waste and prioritise using sustainable materials.
