Tropical crops are an important source of wealth in many countries. The current agribusiness model is based on the production of a final commodity, leading to the production of organic by-products (biowastes) that in many cases contain bioactive compounds with a potential added value. The exploitation of these by-products is the foundation of the circular economy that leads to the generation of greener bioprocesses for the industry with foreseeable economic improvements in production systems. This review aims to point out the idle opportunities of agricultural production systems and their associated biowastes to contribute to the establishment of a bioeconomy. Hence, the focus lies on five tropical extensive crops: coffee, oil palm, sugar cane, banana, and pineapple. This first part of the review explores agricultural wastes originated from the coffee and oil palm industrial process and is oriented on the potential use of these by-products as a starting material for the alternative obtention of chemicals, otherwise obtained from petrochemistry. The second part of the review focuses on prospective use of lignocellulosic rich biowaste that is derived from the industrialization of sugar cane, banana, and pineapple. A fundamental difference for the use of coffee biomass compared to other crops is the presence of numerous bioactive compounds that are not yet properly utilized, such as antioxidants (i.e., caffeic acid, chlorogenic acid, ferulic acid), as well as their possible use in the manufacture of products of interest in the cosmetic (i.e., quinic acid) or pharmaceutical industry (i.e., caffeic acid phenethyl ester). In the case of oil palm, its potential lies in obtaining chemicals such as glycerol and carotenoids, or in the bioenergy production.

在许多国家，热带作物是重要的财富来源。当前的农业综合企业模式基于最终商品的生产，从而导致有机副产品（生物废料）的生产，这种副产品在许多情况下都包含具有潜在附加值的生物活性化合物。这些副产品的开发是循环经济的基础，循环经济导致了该行业绿色环保的生物过程的产生，并在生产系统中实现了可预见的经济改善。这篇综述旨在指出农业生产系统及其相关生物废物闲置的机会，以促进建立生物经济。因此，重点放在五种热带粗粮上：咖啡，油棕，甘蔗，香蕉和菠萝。审查的第一部分探讨了源自咖啡和油棕工业过程的农业废物，并着眼于这些副产物作为替代性获得化学物质（从石油化学中获得）的原料的潜在用途。审查的第二部分集中于潜在使用富含木质纤维素的生物废料，这些生物废料来源于甘蔗，香蕉和菠萝的工业化。与其他农作物相比，使用咖啡生物质的根本区别在于存在许多尚未得到适当利用的生物活性化合物，例如抗氧化剂（即咖啡酸，绿原酸，阿魏酸），以及它们在咖啡中的可能用途。在化妆品（即奎宁酸）或制药行业（即，咖啡酸苯乙酯）。就油棕而言，其潜力在于获得化学物质，例如甘油和类胡萝卜素，或用于生物能源生产。
