Waste Processing Technique
Waste is part of something that is not used, disliked or something to be discarded, which generally comes from activities done by humans (including industrial activities), but not biological (because human waste is not included) and is generally solid.
Sources of waste can vary, including: from households, markets, stalls, offices, public buildings, industries, and roads. Based on their chemical composition, the waste is divided into organic waste and inorganic waste. Research on solid waste in Indonesia shows that 80% is organic waste, and it is estimated that 78% of the waste can be reused.
Waste management is all activities undertaken in handling waste since inflicted up to final disposal. Broadly speaking, activities in waste management include waste generation, garbage collection, transfer and transport, final processing and disposal
