Gasification of plastics-containing residue streams: product gas composition and economics of biochemicals/monomers retrieval/co-production
report
Gasification is a thermochemical process which converts solid fuels into a gas with a useful heating value that can be further processed into a variety of products (heat, power, fuels and chemicals), thus creating smart market opportunities for the valorisation of low-value solid feedstock. As part of the work for development and commercialization of the MILENA and OLGA technologies at industrial scale, this report compiles results of gasification tests performed at pilot scale using waste. The results from the measurement campaign carried out in the pilot MILENA/OLGA show that the product gas is a medium calorific value gas, rich in base chemicals/monomers like ethylene, propylene, styrene and benzene.
The comparison of waste incineration to Waste-to-Energy via gasification shows
that gasification is preferred from both the economical as well as circularity point of view. Gasification of waste produces a gas with considerable value, suitable for power production though allows for further valorisation as well. Co-production of BTX (Benzene, Toluene, Xylene) adds value to Waste-to-Energy processes, but also to other processes such as the production of Renewable Natural Gas (RNG). Finally, removing BTX from product gas is a new way of recycling plastics, thermochemical recycling (second generation recycling).
