Is it the most effective way to deal with waste?

The waste hierarchy provides a guide to sustainable waste management and is based on the following principles in order of preference: prevention, preparing for re-use, recycling, (energy) recovery, and disposal. Include diagram of waste hierarchy.

Where prevention is not possible, and in order of priority, waste materials should be reused, recycled or recovered, including being used as a source of energy. The aim of the Energy Recovery Facility is to move waste up the waste hierarchy so that instead of simply disposing waste into landfill, its energy can be recovered.
