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.

英国正在增加对替代废物处理方案的采用，包括增加材料回收和再循环，以及能够从废物中回收能量的工艺，如厌氧消化（AD），焚烧和先进的热处理工艺，如热解和气化，以减少垃圾填埋和满足英国日益增长的能源需求。目前，英国的垃圾处理设施（mrf、AD工厂、堆肥设施等）每年以7000万英镑的总成本（80英镑/吨的门票费）将27,000吨报废塑料送到垃圾填埋场，使英国在欧盟27国中处于倒数7位，从垃圾填埋场转移，并有可能在2018年达到垃圾填埋场容量。热解为将这些废弃塑料转化为油提供了一个可行的解决方案。运行中的小型热解技术被设计用于处理一致的有机生物质原料，并且受到预处理和精炼过程的规模限制。由于城市固体废物（MSW）流中的塑料混合不一致，从elp中提取的石油产品质量很低，需要进一步加工才能获得高质量的燃料产品。Pearwalk提出了一种新型的集成热解系统，该系统使用连续过程，允许闭环/连续系统跨越各种规模，使用更小但更频繁的废物流。该技术将为AD工厂运营商和材料回收设施（mrf）提供一个重要的机会，将其未分类、未洗涤的废弃塑料转化为清洁的低硫燃料（用于加热和发电），而无需广泛、复杂和昂贵的预处理或精炼过程。该项目旨在设计一个小型热解装置原型，并评估其与各种混合塑料原料的使用情况，以确保能够实现足够的产量，从而从废物解决方案中开发出商业上可行的能源。
