Composting has been used as a means of recycling organic matter back into the soil to improve soil structure and fertility. The composting process has received much attention in recent years because of pollution concerns and the search for environmentally sound methods for treating waste. Waste volumes continue to rise, which leads to loss of resources and increased environmental risks. Open dumping and sanitary landfill is a major method for waste disposal, the Land filling of biodegradable waste is proven to contribute to environmental degradation, mainly through the production of highly polluting leachate and methane gas. Composting aims to stabilization of waste for land filling, volume and mass reduction of solid waste and return of organic substances to the natural cycle. This paper reviews information on the composting for treating waste as a means of addressing the environmental pollution concerns.
