Landfills are breeding grounds for anaerobic bacteria and produce a large amount of methane. Methane has a stronger greenhouse effect than carbon dioxide. Although it can be captured and converted into energy, even the most efficient recovery system still has up to 10% Methane escapes. Because most of the methane produced in landfills comes from organic waste, it can be treated in a greener way. The simplest way is to compost. In fact, two-thirds of the waste in the landfill can Composting, which greatly reduces the production of methane. Due to the high temperature and pressure generated during the composting process, the carbon in organic waste may be partially converted into carbon dioxide and carbon monoxide. So we can consider recombining these organic substances into liquid fuel (ethanol or ethanol) Methanol), or as other industrial raw materials. This text mainly introduces:. ['Methane has more greenhouse effect than carbon dioxide.', 'The capture and utilization of methane by the current methane recovery system is still limited.', 'Disposal of landfill waste by composting can effectively reduce methane production.', 'Compost is a waste treatment method that requires the reorganization of organic waste generated by it.']
