Waste incineration is a central component of sustainable waste management concepts and is intended to dispose of non-recyclable waste in an environmentally friendly manner. In practice, also biogenic waste such as waste wood, paper, cardboard, kitchen and garden waste is treated in WtE plants. For example, the biogenic share in the input of waste incineration plants in Germany is approx. 50% and also around 50 % of the CO2-emission are "green". This raises the fundamental question of whether and when the use of biogenic waste in WtE plants is ecologically sensible, technically feasible and economically viable. Since the practice of incinerating biogenic waste in WtE plants varies greatly internationally and the current situation will be discussed with experts from Europe, Asia and America.

The following questions will then be discussed with the experts:

  • Which biogenic waste should be used in WtE plants from an ecological point of view and which should not?
  • Do we need different solutions in the countries?
  • Which incineration technologies are suitable for the incineration of biogenic waste?
  • How should biobased emissions be assessed (green CO2, CCS, CCU, negative emissions)?
