The remarkable journey of progression of mankind has created various impacts in the form of polluted environment, amassed heavy metals and depleting resources. This alarming situation demands sustainable energy resources and approaches to deal with these environmental hazards and power deficit. Pyrolysis and co-pyrolysis address both energy and environmental issues caused by civilization and industrialization. The processes use hazardous waste materials including waste tires, plastic and medical waste, and biomass waste such as livestock waste and agricultural waste as feedstock to produce gas, char and pyrolysis oil for energy production. Usage of hazardous materials as pyrolysis and co-pyrolysis feedstock reduces disposal of harmful substances into environment, reducing occurrence of soil and water pollution, and substituting the non-renewable feedstock, fossil fuels. As compared to combustion, pyrolysis and co-pyrolysis have less emission of air pollutants and act as alternative options to landfill disposal and incineration for hazardous materials and biomass waste. Hence, stabilizing heavy metals and solving the energy and waste management problems. This review discusses the pyrolysis and co-pyrolysis of biomass and harmful wastes to strive towards circular economy and eco-friendly, cleaner energy with minimum waste disposal, reducing negative impact on the planet and creating future possibilities.

人类进步的非凡旅程以污染环境，重金属堆积和资源枯竭的形式产生了各种影响。这种令人震惊的情况需要可持续的能源和应对这些环境危害和电力短缺的方法。热解和共热解解决了由文明和工业化引起的能源和环境问题。该工艺使用有害废料，包括废轮胎，塑料和医疗废料以及生物质废料（如牲畜废料和农业废料）作为原料，生产天然气，焦炭和热解油，以生产能源。使用有害物质作为热解和共热解原料，可以减少有害物质向环境中的处置，减少土壤和水污染的发生，并用不可再生原料化石燃料代替。与燃烧相比，热解和共热解减少了空气污染物的排放，是垃圾填埋场处置和焚烧危险材料和生物质废物的替代选择。因此，稳定重金属并解决能源和废物管理问题。这篇综述讨论了生物质和有害废物的热解和共热解，以期实现循环经济和生态友好，清洁能源，同时废物处理量最小，减少对地球的负面影响，并创造未来的可能性。稳定重金属并解决能源和废物管理问题。这篇综述讨论了生物质和有害废物的热解和共热解，以期实现循环经济和生态友好，清洁能源，同时废物处理量最小，减少对地球的负面影响，并创造未来的可能性。稳定重金属并解决能源和废物管理问题。这篇综述讨论了生物质和有害废物的热解和共热解，以期实现循环经济和生态友好，清洁能源，同时废物处理量最小，减少对地球的负面影响，并创造未来的可能性。
