Waste occurs in several forms, including:
- Energy - due to energy inefficient practices and technologies, lack of energy storage systems
- Space - a major problem in the built environment - urban planning and architecture
- Food waste, through excessive purchases by consumers, poor choices in foods (non-strable foods) or lack of food storage systems aswell as food recycling systems, food waste by food manufacturers
Waste seperation
Waste needs to be seperated for ecological processing:
- Biodegradable (organic) waste is placed into special bins
- Non-biodegradable waste is seperated into several types of containers (depending on the material it holds) at Civic_amenity_sites, junkyards
- Garbage collection is a supplementary service that is provided in some cities. However, as the waste does not need to be seperated well in these bags (organic remains often remain in discarded food containers, several types of materials/packaging are discarded in a same bag), it is best not used
By seperating the waste this way, the materials can be recycled better (see Cradle-to-cradle). In addition, biogas can be extracted from the biodegradable waste (trough dry or wet anaerobic digestion), or atleast humus can be attained trough composting.
