Abstract

Excessive waste production has led to the concept of a circular bioeconomy to deliver valuable by-products and improve environmental sustainability. The annual worldwide rice production accounts for more than 750 million tons of grain and 150 million tons of husk. Rice husk (RH) contains valuable biomaterials with extensive applications in various fields. The proportions of each component depend primarily on rice genotype, soil chemistry, and climatic conditions. RH and its derivatives, including ash, biochar, hydrochar, and activated carbon have been placed foreground of applications in agriculture and other industries. While the investigation on RH’s compositions, microstructures, and by-products has been done copiously, owing to its unique features, it is still an open-ended area with enormous scope for innovation, research, and technology. Here, we reviewed the latest applications of RH and its derivatives, including fuel and other energy resources, construction materials, pharmacy, medicine, and nanobiotechnology to keep this versatile biomaterial in the spotlight.

稻壳一瞥：从农用工业到现代应用

过多的废物产生催生了循环生物经济的概念，以提供有价值的副产品并改善环境的可持续性。全球水稻年产量超过 7.5 亿吨谷物和 1.5 亿吨稻壳。稻壳（RH）含有宝贵的生物材料，可广泛应用于各个领域。每种成分的比例主要取决于水稻的基因型、土壤化学性质和气候条件。稻壳及其衍生物，包括灰分、生物炭、水炭和活性炭，已成为农业和其他行业的前沿应用。由于 RH 的独特性，人们对其成分、微观结构和副产品进行了大量研究，但它仍然是一个开放的领域，具有巨大的创新、研究和技术空间。在此，我们回顾了 RH 及其衍生物的最新应用，包括燃料和其他能源资源、建筑材料、制药、医药和纳米生物技术，以使这种多用途生物材料成为人们关注的焦点。
