As the use of agricultural waste has risen dramatically in recent years, it has raised concerns regarding environmental issues caused due to the lack of proper disposal methods including practices like uncontrolled landfilling or open-field burning. It cannot only lead to an increase in different greenhouse gases and pollution but also to the depletion of organic resources beneficial for soil quality and fertility. Producing organic fertilizers from agricultural waste can be a sustainable solution since it transforms crop residues, animal manure, fruit and vegetable waste, and various agro-industrial wastes into useful organic fertilizers. The resulting organic fertilizers are said to improve soil structure, water retention, microbial activities, and inclusive macro- and micro-nutrients for healthy growth of plants. The purpose of the project is to examine the variety of agricultural wastes that can be used to manufacture organic fertilizers and evaluate the technologies used to process the wastes. The project can focus on technologies such as composting, vermicomposting, anaerobic digestion, biochar production, and microbial decomposition. Additionally, it includes an analysis of impacts of the produced organic fertilizers in terms of soil characteristics, presence of soil nutrients, agricultural output, and sustainability of the soil for a long time. Furthermore, the project touches upon the benefits of agricultural waste recycling and sustainable agriculture in general, thereby showing the economic, environmental, and social importance of the topic.
