This paper reviews the sector of waste-to-energy looking at the main processes and feedstock involved. Within this, incineration, gasification, pyrolysis, anaerobic digestion and hydrothermal liquefaction are named and discussed. Through the discussions and scrutiny, manure is highlighted as a significant source of ammonia, methane, and nitrogen oxides emission, estimated to be 40%, 22.5% and 28% respectively of the total UK's anthropogenic emissions. Manure, and indeed the pollution it poses, are shown to remain largely ignored. In waste to energy processing, manure is capable of providing biogas for a number of pathways including electricity generation. Anaerobic digestion is highlighted as a suitable process with the crucial capability of drastically reducing the pollution potential of manure and slurry compared to no processing, with up to 90% reduction in methane and 50% reduction in nitrogen oxide emissions. If the majority of the 90 million tonnes of manure and slurry in the UK were to be processed through biogas harvesting, this could have the potential of producing more than 1.615 TWh of electricity. As such, the economics and legislation surrounding the implementation of anaerobic digestion for manure and slurry are discussed. In the end, restraining factors that limit the implementation of anaerobic digesters on farms in the UK are discussed. These are found to be mainly capital costs, lack of grants, insufficiently high tariff systems, rather than low gas yields from manure and slurry.

本文回顾了废物转化为能源的领域，着眼于主要过程和所涉及的原料。在其中，对焚烧，气化，热解，厌氧消化和水热液化进行了命名和讨论。通过讨论和审查，粪便被强调为氨，甲烷和氮氧化物的重要排放源，估计分别占英国人为排放总量的40％，22.5％和28％。粪便及其构成的污染，实际上仍然被忽略。在废物转化为能源的过程中，粪便能够为包括发电在内的许多途径提供沼气。厌氧消化被认为是一种合适的工艺，与不进行处理相比，其具有显着降低粪便和淤浆污染潜力的关键能力，最多可减少90％的甲烷和50％的氮氧化物排放。如果英国的9000万吨粪便和泥浆中的大部分将通过沼气收集进行处理，则可能产生超过1.615 TWh的电力。因此，讨论了围绕粪便和泥浆进行厌氧消化的经济学和法规。最后，讨论了限制英国厌氧消化池实施的限制因素。发现这些主要是资本成本，缺乏赠款，高额的关税制度，而不是粪便和淤浆产生的天然气产量低。如果英国的9000万吨粪便和泥浆中的大部分将通过沼气收集进行处理，则可能产生超过1.615 TWh的电力。因此，讨论了围绕粪便和粪便进行厌氧消化的经济学和法规。最后，讨论了限制英国厌氧消化池实施的限制因素。发现这些主要是资本成本，缺乏赠款，高额的关税制度，而不是粪便和淤浆产生的天然气产量低。如果英国的9000万吨粪便和泥浆中的大部分将通过沼气收集进行处理，则可能产生超过1.615 TWh的电力。因此，讨论了围绕粪便和粪便进行厌氧消化的经济学和法规。最后，讨论了限制英国厌氧消化池实施的限制因素。发现这些主要是资本成本，缺乏赠款，高额的关税制度，而不是粪便和淤浆产生的天然气产量低。讨论了限制英国厌氧消化池实施的限制因素。发现这些主要是资本成本，缺乏赠款，高额的关税制度，而不是粪便和淤浆产生的天然气产量低。讨论了限制英国厌氧消化池实施的限制因素。发现这些主要是资本成本，缺乏赠款，高额的关税制度，而不是粪便和淤浆产生的天然气产量低。
