The area of agricultural wastes valorisation to fertilizers is attracting growing attention because of the increasing fertilizer prices of fertilizers and the higher costs of waste utilization. Despite the scientific and political interest in the concept of circular economy, few studies have considered the practical approach towards the implementation of elaborated technologies. This article outlines innovative strategies for the valorisation of different biobased wastes into fertilizers. The present work makes a significant contribution to the field of new ideas for waste biomass management to recover significant fertilizer nutrients. These results emphasize the importance of the biomass use as a base of renewable resources, which has recently gained special importance, especially in relation to the outbreak of pandemia and war. Broken supply chains and limited access to deposits of raw materials used in fertilizer production (natural gas, potassium salts) meant that now, as never before, it has become more important and feasible to implement the idea of a circular economy and a green deal. We have obtained satisfactory results that demonstrate that appropriate management of biological waste (originating from agriculture, food processing, aquaculture, forest, pharmaceutical industry, and other branches of industry, sewage sludge) will not only reduce environmental nuisance (reducing waste heaps), but will also allow recovery of valuable materials, such as nitrogen (especially valuable amino acids), phosphorus, potassium, microelements, and biologically active substances with properties that stimulate plant growth. The results reported here provide information on production of biobased plant protection products (bioagrochemicals) from agri-food waste. This work reports an overview of biopesticides and biofertilisers production technologies and summarizes their properties and the mechanisms of action.
农业废弃物肥料化利用日益受到关注，这是由于肥料价格不断上涨，以及废物利用成本不断上升所致。尽管科学界和政治界对循环经济的概念很感兴趣，但很少有研究考虑实施复杂技术的实际方法。本文概述了将不同生物基废物转化为肥料的创新策略。本工作为废物生物质管理的新思路提供了重要贡献，以回收重要的肥料养分。这些结果强调了生物质作为可再生资源基础的重要性，这在最近特别是在大流行病和战争爆发后显得尤为重要。供应链中断和生产肥料（天然气、钾盐）所需原材料的获取有限，这意味着现在比以往任何时候都更重要和可行的是实施循环经济和绿色协议的理念。我们取得了令人满意的结果，表明对生物废物（来自农业、食品加工、水产养殖、林业、制药业和其他工业部门、污水污泥）的适当管理不仅可以减少环境公害（减少废物堆），还可以回收有价值的物质，如氮（特别是有价值的氨基酸）、磷、钾、微量元素和具有刺激植物生长特性的生物活性物质。这里报道的结果提供了关于从农业食品废物生产生物基植保产品（生物农药）的信息。这项工作概述了生物农药和生物肥料生产技术，并总结了它们的性质和作用机制。
