What are the benefits and drawbacks of using incineration to convert waste into energy?4 answersIncineration has been proposed as a method to convert waste into energy. The benefits of incineration include energy recovery and volume reduction of waste. It is considered a leading approach for effectively recovering energy from municipal solid waste (MSW). Waste incineration with energy yield is advantageous for handling waste problems and positively affects climate change. Additionally, waste incineration power plants can generate a large amount of electric energy while harmlessly treating garbage, which can help alleviate electricity shortages in cities. However, there are drawbacks to incineration as well. Incinerators emit more greenhouse gas emissions per unit of electricity produced than any other power source and contribute to air pollution, particularly in environmental justice communities. They also emit more criteria air pollutants than replacement sources of energy, such as natural gas. The release of persistent organic pollutants is a major public concern associated with incineration.
