Next-generation slag bath gasification for variable fuel qualities, e.g. from waste, is being developed at the FlexiSlag test facility in Freiberg.

Within “Waste4Future”, new possibilities for the chemical recycling of waste containing plastics were created, in particular by means of pyrolysis and gasification technologies. The focus was on the material use of plastic fractions that cannot be recycled (gaseous, liquid, solid) or residual materials from sorting. Based on an intelligent control system, these processes were evaluated with regard to the potential of selected input materials for chemical recycling up to pilot scale. The results also include the balancing and evaluation of various process options, improved knowledge for the analysis of carbon-containing input materials and products for use in chemical recycling and the creation of process chain models.
