Instead of letting this gas escape and pollute the air, some waste management companies are employing a capture and purification system that allows them to convert the landfill gas (LFG) into energy.
取代允许这种气体自由挥发并污染空气的是，一些废物处理公司采用收集净化系统，使得他们可以把这种气体(LFG)转化成能量。
Leachate and landfill gas (LFG) are released continually in the process of landfill stabilization, which causes a series of resources and environment problems.
垃圾填埋场稳定化过程中不断释放出渗滤液与填埋气体(LFG)，能够产生一系列的资源与环境问题。
It thus provides a scientific basis for environmental impact prediction and assessment of LFG generation and for designing and management of LFG collection and treatment systems.
该模型的应用可为垃圾填埋场进行填埋气体产生量预测及收集处理系统的设计、管理提供合理的依据。
