“Closing two loops”-The importance of energy recovery in the “closing the loop” approach

The EU is experiencing economic growth that exceeds domestic raw material/energy production. The EC is trying to solve this problem of the unsustainability of its economic development through two separate legislative frameworks-one trying to solve material supply problems, and one for solving problems of energy dependence. This division is also present in waste-related legislation where emphasis is put on “closing the loop” on the material side through material recovery. In this chapter, a “closing two loops” approach is defined, which builds upon material recovery-based approach to waste management and boosts its sustainability by at the same time closing the loop from two sides-material and energy. The significance of energy recovery is demonstrated through the use of cumulative energy demand-based indices, combined with LCA-based system modeling, for comparison of different scenarios that use material and energy recovery to a different extent and, at the same time, meet all current legislative goals.
