What are possibles sources of waste and pollution in a system?
There are six major types of waste created in a material system: organic waste, recyclable waste, non-recyclable waste, toxic waste, nuclear toxic waste and space waste. Organic waste can be more readily absorbed back into the system, recyclable waste can be re-processed into another form of material which can also be absorbed back into the system eventually. Toxic waste, nuclear waste, and space waste however, cannot be recycled back into the system and remain useless and contaminate the outer ecosystem until breaking down.
