Rapid population growth and consumption of goods and services imply that demand for energy and resources increases continuously. Energy consumption linked to non-renewable resources contributes to greenhouse gas emissions and enhances resource depletion. In this context, the use of agricultural solid residues such as rice husk, coffee husk, wheat straw, sugar cane bagasse, among others, has been widely studied as an alternative energy source in order to decrease the use of fossil fuels. However, rice husk is among those agricultural residues that are least used to obtain energy in developing countries. Approximately 134 million tonnes of rice husk are produced annually in the world, of which over 90% are burned in open air or discharged into rivers and oceans in order to dispose of them. This review examines the energetic potential of agricultural residues, focused on rice husk. The review describes direct combustion and fast pyrolysis technologies to transform rice husk into energy considering its physical and chemical properties. In addition, a review of existing studies analyzing these technologies from an environmental life cycle thinking perspective, contributing to their sustainable use, is performed.
人口的快速增长和商品及服务的消费意味着能源和资源的需求不断增加。与不可再生资源相关的能源消耗导致温室气体排放和资源枯竭。在这种情况下，人们广泛研究了利用农业固体残留物（如稻壳、咖啡壳、麦秆、甘蔗渣等）作为替代能源的方法，以减少对化石燃料的使用。然而，稻壳是发展中国家农业残留物中使用最少的能源获取来源之一。全球每年约生产 1.34 亿吨稻壳，其中超过 90%的稻壳被露天燃烧或排放到河流和海洋中进行处理。本文综述了农业残留物的能源潜力，重点关注稻壳。本文描述了直接燃烧和快速热解技术，考虑到稻壳的物理和化学性质，将其转化为能源。此外，还对现有的从环境生命周期思维角度分析这些技术的研究进行了综述，以促进其可持续利用。
