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
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.
