STUDY ON COMPOSTING OF DIFFERENT WASTE USING INDIGENIOUS MICROORGANISMS (IMO) – A REVIEW

In the municipal solid wastes usually contain the component of organic solid waste like food waste, garden waste that disposed directly into the landfill. 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. Direct disposal to landfill can cause impacts to the environment. Composting of organic solid waste is seen as a waste treatment method to avoid the waste from being dumped at the landfill. The utilization of organic additives towards composting process would produce an environmental product of compost. IMO used as an organic additive during composting were prepared according to the method from Explain in this study. The preparation of IMO consists of several phases include phase I until V with a mixture of various materials for each phase. This paper reviews information on the composting of different waste using indigenous microorganisms.
