Generating energy from waste through processes such as anaerobic digestion, gasification, incineration, etc.

The principles of a circular economy concern designing out waste, regenerating ecosystems and keeping items in use. Decoupling the economy from material flows—improving the rate of resource productivity faster than the economic growth rate—is also a consistent guide. By evolving with the growing number of applications of circular economy principles, and consolidating these strategies across thematic areas, Circle Economy’s Key Elements Framework (KE) renders the elements of the circular economy salient and serves as a basis to derive contextual strategies and interventions. 


The Framework consists of:
- Core Elements: Activities directly handling product or material flows; and uniquely,
- Enabling Elements: those that remove obstacles for core actors.

Circle Economy's framework of strategies and activities that define the circular economy

Generating energy from waste

Processing waste streams into fuels such as biogas, biofuels, pellets, etc.

Processing waste into fuel

Recovering and reusing waste heat, gas, etc. for energy

Recovery and reuse of waste energy

Recover waste energy or generate fuels and energy from waste streams

Energy recovery from waste

Reuse, repurpose, and recycle waste streams within the same industry

Valorise waste streams - closed loop

Reuse, repurpose, and recycle waste streams within other industries

Valorise waste streams - open loop

Utilise waste streams as a source of secondary resources and recover waste for reuse and recycling
