Organic waste biomass is transformed to biogas via anaerobic digestion. Biogas is typically used as a gaseous fuel to produce heat and power, incentivized by regulatory support schemes in different regions and countries. However, energy production via biogas combustion is limited to local sites, and a lower fuel quality of biogas than natural gas is another limitation on the direct use of biogas as a fuel. Alternative ways are to employ biogas as (1) pyrolysis medium to effectively modify the quality and quantity of pyrolytic products and (2) feedstock for the production of high-value commodity chemicals. In this regard, this review is aimed at providing an overview on the use of biogas either as pyrolysis medium or as renewable chemical feedstock.

有机废物生物质通过厌氧消化转化为沼气。在不同地区和国家的监管支持计划的激励下，沼气通常用作产生热量和电力的气体燃料。然而，通过沼气燃烧产生的能源仅限于当地，沼气的燃料质量低于天然气是直接使用沼气作为燃料的另一个限制。替代方法是使用沼气作为 (1) 热解介质以有效改变热解产品的质量和数量，以及 (2) 用于生产高价值商品化学品的原料。在这方面，本综述旨在概述沼气作为热解介质或可再生化学原料的用途。
