The article discusses how household and urban waste can be turned into valuable energy through a process called gasification. The researchers looked at ways to improve the treatment of waste materials like paper, plastic, and food to make them better suited for this process. They found that by separating recyclable materials more efficiently, municipalities can increase their recycling rates and reduce the need for landfills and incineration. This approach not only helps the environment but also creates new opportunities for turning waste into a useful energy source.
