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.
人类的显著进步之旅以环境污染、重金属积累和资源枯竭的形式产生了各种影响。这种令人担忧的情况要求可持续的能源资源和方法来应对这些环境危害和能源短缺。热解和共热解解决了文明和工业化带来的能源和环境问题。这些过程使用危险废物材料，包括废轮胎、塑料和医疗废物，以及生物质废物，如牲畜废物和农业废物作为原料，生产气体、炭和热解油，用于能源生产。将危险材料用作热解和共热解的原料，可以减少有害物质排放到环境中，降低土壤和水污染的发生，替代不可再生原料、化石燃料。与燃烧相比，热解和共热解的空气污染物排放量较少，是危险材料和生物质废物的垃圾填埋处置和焚烧的替代选择。因此，稳定重金属并解决能源和废物管理问题。本文综述了生物质和有害废物的热解和共热解，旨在实现循环经济和生态友好、清洁的能源，尽量减少废物处理，减少对地球的负面影响，并创造未来的可能性。
