Landfilling involves burying waste in specially designed landfills. Modern landfills are engineered to prevent leachate from contaminating groundwater and to capture landfill gas for energy production. Landfilling is a relatively inexpensive waste disposal option, but it can take up large areas of land and can generate methane emissions. Proper landfill management, including leachate collection and gas capture, is essential to minimize environmental impacts.

4.3. Composting

Composting is a biological process that decomposes organic waste, such as food scraps and yard waste, into a nutrient-rich soil amendment called compost. Composting can reduce the volume of waste sent to landfills and can produce a valuable product for use in agriculture and horticulture. Composting can be done on a small scale in backyards or on a large scale in centralized composting facilities. Careful management is necessary to control odors and prevent the spread of pathogens.

4.4. Anaerobic Digestion

Anaerobic digestion is a biological process that decomposes organic waste in the absence of oxygen, producing biogas and digestate. Biogas can be used as a renewable energy source, while digestate can be used as a fertilizer or soil amendment. Anaerobic digestion is an effective way to treat a variety of organic wastes, including food waste, manure, and sewage sludge. It is often used as a waste stream pre-treatment before landfilling to reduce the volume of waste that needs to be landfilled.

4.5. Pyrolysis and Gasification

Pyrolysis and gasification are thermal processes that decompose waste at high temperatures in the absence or presence of limited oxygen, producing syngas and biochar. Syngas can be used as a fuel or chemical feedstock, while biochar can be used as a soil amendment or carbon sequestration agent. Pyrolysis and gasification can be used to treat a variety of wastes, including plastics, tires, and biomass. These technologies can offer a sustainable way to convert waste into valuable products and reduce reliance on fossil fuels.
