Over the last decade, commercialization of insects for food and feed has been exponentially increasing. Insect protein is emerging as a sustainable livestock feed and human food alternative due to its low land and carbon footprint. The principles of insect industry are deeply embedded in the core values of sustainability and circular economy. Black soldier fly (BSF) is the crown jewel of insect industry and is one of the most commercially farmed insects. However, this steadfast growth is accompanied by generation of insect based biowaste such as dead flies and pupae exuviae. This will be a major waste fraction from this industry. This study discusses the valorization potential of this waste into chitin (which finds application in cosmetics, bioplastics, and pesticides, among other industries), biogas, fertilizer, and biochar. There is need to conduct more explorative research on value proposition of insect based biowaste to ensure that this industry can comply fully with circular economy and sustainability principles.
在过去的十年中，昆虫作为食品和饲料的商业化呈指数级增长。由于昆虫的土地和碳足迹低，昆虫蛋白作为一种可持续的牲畜饲料和人类食品替代品正在崭露头角。昆虫产业的原则深深植根于可持续性和循环经济的核心价值观中。黑水虻（BSF）是昆虫产业的瑰宝，也是商业养殖昆虫之一。然而，这种稳步增长伴随着基于昆虫的生物废物的产生，如死虫和蛹蜕。这将是该行业的主要废物部分。本研究讨论了将这种废物转化为几丁质（在化妆品、生物塑料和农药等行业中有应用）、沼气、肥料和生物炭的增值潜力。需要对基于昆虫的生物废物的价值主张进行更多的探索性研究，以确保该产业能够完全符合循环经济和可持续性原则。
