Decarbonisation refers to the process of reducing carbon emissions in various sectors of the economy. The treatment and disposal of non-hazardous waste sector is one of the areas where decarbonisation is essential. This sector is responsible for managing waste generated from households, commercial establishments, and industries. The management of non-hazardous waste involves various activities such as collection, transportation, treatment, and disposal. These activities contribute to carbon emissions, which have adverse effects on the environment and human health. This article discusses the importance of decarbonisation in the treatment and disposal of non-hazardous waste sector, the main sources of carbon emissions, strategies for reducing emissions, challenges facing decarbonisation, and the implications of decarbonisation for this sector.

Importance of Decarbonisation in the Treatment and Disposal of Non-Hazardous Waste Sector

The treatment and disposal of non-hazardous waste sector is a significant contributor to carbon emissions. According to the European Environment Agency, this sector accounted for 3.6% of the total greenhouse gas emissions in the European Union in 2018 (EEA, 2020). Carbon emissions from this sector are mainly from the transportation of waste to treatment and disposal facilities, energy consumption during treatment and disposal processes, and emissions from landfills. Decarbonisation is essential in this sector because it helps to mitigate the adverse effects of climate change, reduce air pollution, and promote sustainable waste management practices.

Mitigating the Adverse Effects of Climate Change

Carbon emissions from the treatment and disposal of non-hazardous waste sector contribute to climate change, which has adverse effects on the environment and human health. Climate change leads to extreme weather events such as floods, droughts, and hurricanes, which cause property damage and loss of lives. Decarbonisation in this sector helps to reduce carbon emissions, which mitigates the adverse effects of climate change.

Reducing Air Pollution

The treatment and disposal of non-hazardous waste sector contributes to air pollution, which has adverse effects on human health. Emissions from waste transportation vehicles, treatment plants, and landfills contribute to air pollution. Decarbonisation in this sector helps to reduce air pollution, which improves air quality and promotes public health.

Promoting Sustainable Waste Management Practices

Decarbonisation in the treatment and disposal of non-hazardous waste sector promotes sustainable waste management practices. Sustainable waste management practices involve reducing waste generation, reusing and recycling waste, and treating and disposing of waste in an environmentally friendly manner. Decarbonisation helps to reduce carbon emissions, which promotes sustainable waste management practices.

Main Sources of Carbon Emissions in the Treatment and Disposal of Non-Hazardous Waste Sector

The treatment and disposal of non-hazardous waste sector contributes to carbon emissions through various activities. The main sources of carbon emissions in this sector include:

Transportation of Waste

The transportation of waste from households, commercial establishments, and industries to treatment and disposal facilities contributes to carbon emissions. Waste transportation vehicles emit carbon dioxide and other greenhouse gases, which contribute to climate change.

Energy Consumption during Treatment and Disposal Processes

The treatment and disposal of non-hazardous waste involves various processes that consume energy. These processes include sorting, shredding, composting, incineration, and landfilling. Energy consumption during these processes contributes to carbon emissions.

Emissions from Landfills

Landfills are the final disposal sites for non-hazardous waste. Landfills emit methane, a potent greenhouse gas, during the decomposition of organic waste. Methane emissions from landfills contribute to climate change.

Strategies for Reducing Carbon Emissions in the Treatment and Disposal of Non-Hazardous Waste Sector

Reducing carbon emissions in the treatment and disposal of non-hazardous waste sector requires the implementation of various strategies. The following are some of the strategies that can be implemented to reduce carbon emissions in this sector:

Waste Reduction

Waste reduction involves reducing the amount of waste generated. This strategy can be achieved through various measures such as promoting the use of reusable products, reducing packaging, and implementing waste reduction policies in industries and commercial establishments. Waste reduction helps to reduce the amount of waste that requires treatment and disposal, which reduces carbon emissions.

Waste Recycling

Waste recycling involves the collection, sorting, and processing of waste materials to produce new products. Recycling reduces the amount of waste that requires treatment and disposal, which reduces carbon emissions. Recycling also saves energy and reduces the need for raw materials, which reduces carbon emissions from the production of new products.

Waste-to-Energy

Waste-to-energy involves converting waste into energy through incineration or other thermal processes. This strategy helps to reduce carbon emissions by reducing the amount of waste that requires disposal in landfills. Waste-to-energy also generates renewable energy, which reduces the need for fossil fuels, which reduces carbon emissions.

Challenges Facing Decarbonisation in the Treatment and Disposal of Non-Hazardous Waste Sector

Decarbonisation in the treatment and disposal of non-hazardous waste sector faces various challenges. The following are some of the challenges facing decarbonisation in this sector:
