Description

technical field

[0001] The invention relates to a methane oxidation covering material of domestic waste landfill, which relates to a field covering material for reducing greenhouse gas emission of domestic waste landfill. It belongs to the field of solid waste recycling. Background technique

[0002] Methane is an important greenhouse gas, which contributes about 20% to the global warming effect. Due to the imbalance between methane production and consumption, in the past 300 years, the concentration of methane in the atmosphere has risen from 0.75hd / L to 1.71hd / L, and it is rising rapidly at a rate of 1%-2%.

[0003] According to recent studies, landfills are the third largest source of methane in the atmosphere after wetlands and rice fields. According to statistics, by 2002, the annual discharge of solid waste in the world is about 8-10 billion tons, and our country is about 600 million tons. Municipal waste is an important part of solid waste...
