Pine needles (PNs) are one of the largest bio-polymer produced worldwide. Its waste, i.e., fallen PNs, is mostly responsible for forest fires and is a major challenge. In present article, we have reviewed differenteffortsmadeto tackle this situation. PNs have been used in various fields such asin composite, water purification industries,electronic devices, etc. Gasification is one of the appealing processes for turning PNs into bio-energy; pyrolysis technique has been employed to create various carbon-based water purification materials; saccharification combined with fermentation produced good yields of bio-ethanol; Pd or Ni/PNs biocatalyst showed good catalytic properties in variousreactionsand pyrolysis with or without catalyst is an alluring technique to prepare bio-fuel. Nano cellulose extracted from PNs showed appealing thermal and mechanical strength. The air quality of nearbyenvironment was examinedby studying the magnetic properties of PNs. Packing materials made of PNs showed exceptional ethylene scavenging abilities.
松针是世界上产量最大的生物聚合物之一。其废弃物，即掉落的松针，是森林火灾的主要原因，也是一个主要的挑战。在本文中，我们综述了为解决这一问题所做的不同努力。松针已被应用于各种领域，如复合材料、水净化工业、电子设备等。气化是将松针转化为生物能源的一种有吸引力的方法；热解技术已被用于制造各种基于碳的水净化材料；糖化与发酵相结合产生了高产量的生物乙醇；Pd 或 Ni/PNs 生物催化剂在各种反应中表现出良好的催化性能，并且有无催化剂的热解是制备生物燃料的诱人技术。从松针中提取的纳米纤维素表现出令人感兴趣的热学和力学强度。通过研究松针的磁性来检测附近环境的空气质量。由松针制成的包装材料显示出出色的乙烯清除能力。
