The rising worldwide need for energy, driven by industrial expansion, population increase, and transportation demands, poses a substantial issue. Microalgae are extremely promising raw materials for biofuel production, and pyrolysis is an efficient method of turning biomass into bioenergy. However, biofuels generated from microalgae pyrolysis frequently have inferior fuel characteristics due to high quantities of moisture and nitrogen. At the same time, population growth has resulted in a large increase in plastic trash, causing serious environmental issues. While some plastics are recycled, a large portion stays useless, adding to environmental issues. The present research looks at how to overcome these issues by investigating the co-pyrolysis of waste plastics and microalgae biomass. This technique provides synergistic benefits for both fuel and value-added product manufacturing. The resultant materials can be utilized as chemicals and to absorb pollutants, providing ecologically acceptable waste management solutions and supporting sustainability. Co-pyrolysis inhibits the transformation of oxygen and nitrogen to bio-oil in a highly efficient method, increasing oxygen release as HO and nitrogen conversion to gas products. The paper fully examines the physicochemical features of microalgae biomass and waste plastics, offering a thorough overview. It also summarizes the present research state of microalgae biomass and plastic co-pyrolysis technology, highlighting the synergistic impacts and identifying future development opportunities. The review's last part addresses the economic feasibility, critical challenges, and the potential of co-pyrolysis processes, offering light on this method of waste disposal and sustainable energy generation.

促进可持续发展：微藻生物质和废塑料的共热解用于可再生能源和减少废物


在工业扩张、人口增长和运输需求的推动下，全球能源需求不断增长，这是一个重大问题。微藻是极有前途的生物燃料生产原料，而热解是将生物质转化为生物能源的有效方法。然而，由于含有大量水分和氮气，微藻热解产生的生物燃料通常具有较差的燃料特性。与此同时，人口增长导致塑料垃圾大量增加，造成严重的环境问题。虽然一些塑料被回收，但很大一部分仍然无用，加剧了环境问题。目前的研究着眼于如何通过研究废塑料和微藻生物质的共热解来克服这些问题。该技术为燃料和增值产品制造提供协同效益。所得材料可用作化学品并吸收污染物，提供生态上可接受的废物管理解决方案并支持可持续性。共热解以高效的方法抑制氧气和氮气转化为生物油，增加氧气释放为 H2O 和氮气转化为气体产品。该论文全面考察了微藻生物质和废塑料的理化特征，提供了全面的概述。报告还总结了微藻生物质与塑料共热解技术的研究现状，强调了协同影响并确定了未来的发展机会。该评论的最后一部分讨论了共热解过程的经济可行性、关键挑战和潜力，为这种废物处理方法和可持续能源生产提供了线索。
