众所周知，在固体废物工业中，垃圾填埋会产生热量。直到最近，回收热量和利用垃圾填埋场作为热源的努力还不存在。垃圾填埋场的热量是由化学和生物过程中各种废物的降解产生的。在某些情况下，堆填区的废物温度可在20摄氏度至90摄氏度以上。地热供暖系统的原理可以应用于垃圾填埋场，以回收空间供暖和其他目的的热量。基于垃圾填埋场的地热系统比地面系统更有效，因为垃圾填埋场的环境温度比地面温度高10到45摄氏度。案例研究表明，与传统的空间供暖技术相比，基于垃圾填埋场的地热系统具有很高的效率和成本效益，投资回收期简单，在4到7年的范围内。
It is well known in the solid waste industry that waste disposed in landfills generates heat. Until recently, efforts to recover the heat and use landfills as a heat source did not exist. Landfill heat is generated from degradation of various waste types as a result of chemical and biological processes. Waste temperatures in landfills can range from 20oC to over 90oC under certain conditions. The principles of geothermal heating systems can be applied to landfills to recover the heat for space heating and other purposes. Landfill based geothermal systems are more efficient than ground based systems because ambient temperatures in landfills are warmer than the ground by 10oC to 45oC. Case studies indicate the high level of efficiency and cost effectiveness of landfill based geothermal systems, with simple payback periods in the range of 4 to 7 years when compared to conventional space heating technology.
