Chemical feedstock from plastics waste / Pyrolysis pilot plant planned in Czech Republic
Unipetrol is building a pyrolysis plant for plastics waste in Litv??nov (Photo: Unipetrol)According to the Ministry of Industry and Trade, more than 400,000 t of plastics waste is generated annually in the Czech Republic, with roughly 37% used for recycling and 18% as energy for heat and/or electricity generation. The circular economy project aims to find a sustainable use for the remaining 45%. Unipetrol???s objective is to develop a functional pyrolysis technology for reusing plastics and rubber from waste tyres. Liquids generated during pyrolysis can subsequently be processed using refining or petrochemical technologies and ultimately be used to manufacture plastics such as polyethylene, polypropylene and polystyrene, in addition to petrol and diesel fuel, it notes.
Unipetrol???s pilot pyrolysis unit, which will test various types of input materials, including single-type plastics waste and mixed plastics, will use the ???Biogreen??? process owned by France???s ETIA (Compi??gne; www.etia-group.com) that can convert biomass, plastics and waste into energy or renewable products. Unipetrol board member Tom??Å¡ Herink said the research will try to resolve several questions, including how to improve the quality of liquid and gaseous pyrolytic byproducts, how to store the liquid to avoid repeat polymerisation and how to transport it over long distances.
Ji???? H??jek, director of the Unipetrol Centre for Research and Education, said the Czech petchems producer wants to find out what impact the basic parameters of the input materials have on the utilisation ratio and on the quality of the final product. H??jek said the plant operator will also be looking for a safe mixing ratio of the pyrolysis output into the existing production process, so that the continuity of plastics production is not compromised.19.03.2020 Plasteurope.com [244737-0]
