PyroGen - End of life plastic to oil pyrolysis for a closed loop energy from waste process

The UK is increasing its adoption of alternative waste disposal options including increasedmaterial recovery & recycling, & processes that enable the recovery of energy from wastesuch as anaerobic digestion (AD), incineration & advanced thermal treatment processes suchas pyrolysis & gasification to reduce landfilled waste & meet the UK’s increasing energyneeds. Currently, UK waste disposal facilities (MRFs, AD plants, composting facilities, etc.)send 27,000kt of end-of-life plastics to landfill at a total cost of ~£70M (gate fees of £80/t)per annum, placing the UK in the bottom 7 of the EU27 for diversion from landfill & at riskof reaching landfill capacity by 2018.Pyrolysis provides a viable solution for the conversion of these end of life plastics back intooil. Smaller scale pyrolysis technologies in operation have been designed to handle aconsistent organic biomass feedstock & are limited in scale by pre-treatment & refinementprocesses. Due to the inconsistent mix of plastics in the municipal solid waste (MSW) stream,the quality of oil products derived from ELPs is low and further processing is required to givea quality fuel product. Pearwalk propose a novel integrated pyrolysis system which uses acontinuous process that will allow for a closed loop/continuous system across a variety ofscales using smaller but more frequent waste streams. The technology will provide asignificant opportunity for AD plant operators & material recover facilities (MRFs) to turntheir unsorted, unwashed waste end of life plastics into clean low sulphur fuels (for heating &energy generation) without the need for extensive, complex & costly pre-treatment orrefinement processes. The project aims to design a small scale pyrolysis rig prototype & toevaluate its use with a variety of mixed end of life plastic feedstocks to ensure that sufficientoutput yields can be achieved for a commercially viable energy from waste solution to bedeveloped.
