With limited global resources and growing public awareness of the negative consequences of our "throwaway culture," a shift to a circular economy appears to be a viable option. In a nutshell, this entails extending the life of things and recovering materials or other benefits when they can't be repaired. The generation of energy from garbage – whether electricity or heat – that can subsequently be utilised in homes and businesses is a logical aspect of this circular thinking movement. The waste hierarchy is the best way to put the concept of generating energy from garbage in context. The waste hierarchy tool shows which measures to reduce and manage waste should be prioritised in order of preference.
