At the VAM waste treatment company in Wijster a demonstration is in progress of bioreactor technology for the treatment of mechanically separated organic residue (MSOR) of a waste separation plant. This bioreactor is an in situ fermentation cell in which physical, chemical and biological processes are controlled by leachate circulation in such a way to ensure obtaining a product with acceptable rest-emissions. A 49000 tonne demonstration cell has been built and methanogenic conditions are being realized. During operation measures are taken to limit emissions from the bioreactor and to optimize the conversion of waste to energy.
