Waste can generally be divided into organic and inorganic. All organic waste (except excrete from humans or animals who are sick) in fact can be processed into compost in aerobic and anaerobic. Also in the anaerobic process, biogas can be generated that can become fuel. Inorganic waste can be subdivided into salable waste (plastic, glass bottles, metal, paper and cans) and dispose of trash worthy.
Trash still has economic value if managed properly. This we can see with having different products produced from waste, such as the recycling plant, handicrafts, compost, liquid fertilizer (the processed waste water from the gutter), briquettes (solids that can become fuel), biogas , and block (the processed sand from the gutter). Trash worth wasting large amounts can be managed by burning power plants. Waste combustion can be used as a decomposer ingredient. In fact, there are now also has technology that allows urine can be processed into the water safe to drink.
By considering this, of course, the paradigm of waste is waste material can be converted into raw materials which can still be valuable economically. Thus, it will pop business opportunities related to waste management. So, in the end, waste is not quite waste that cannot be processed anymore, right?
