Bio–wastes and their utilization has been increasing enormously, due to its generation and management practices towards making the clearner environment. Bio–waste disposal that follow the emerging global human population has commended the hunt to certain methods sustainably for the bio–waste management to overwhelmed the ecological issues, prompted by means of the collection of such waste materials. The bio–conversion process of the various bio–wastes into high value added products seems to be practicable in various venues in terms of technological and financial supports. Thereby, this preface presentat about of bio–wastes management and new trends towards circular economy and challenges to acheive it by considering the Virtual Special Issue (VSI) dedicated in Bioresourse Technology Journal.

由于其产生和管理实践旨在营造更清洁的环境，因此生物废物及其利用已大大增加。随着全球人口的不断涌现，生物废物处理已经赞扬了对生物废物管理的某些可持续方法的探索，以解决因收集此类废物而引发的生态问题。就技术和资金支持而言，将各种生物废物转化为高附加值产品的生物转化过程似乎在各个场所都是可行的。因此，本序言介绍了生物废物管理和循环经济的新趋势，以及通过考虑生物资源技术期刊中的虚拟特刊 (VSI) 实现循环经济所面临的挑战。
