The dump sites virtually become a breeding ground for all kinds of diseases (Sahu, 2007). One of the major impacts from open dumping is the release of greenhouse gases, mainly methane and carbon dioxide, are produced from the biodegradation of wastes under anaerobic conditions through microbial activities (Chiemchaisri,...
