Abstract
A useful way to reduce food waste (FW) environmental impact is by turning it into biofertilizer. The conversion of FW into biogas can be used for agricultural applications after being converted into biofertilizer through techniques such as anaerobic digestion (AD), composting, and vermicomposting. Through use of food waste digestate (FWD) as a biofertilizer, nutrient loops are closed and waste is reduced. Instead of dumping FW into landfills, which contributes to greenhouse gas emissions, the waste is processed into digestate and fed to plants, creating a sustainable cycle. In addition to enhancing soil micronutrients, reducing environmental pollution, and reducing the need for chemical fertilizers, FW biofertilizers contribute to the circular economy. There are several methods for applying FWD to agricultural fields, including surface spreading, injection, and incorporation into the soil. Technology for converting FW to biofertilizers is sustainable, and invention productivity can be increased through well-procedure regulatory approaches and innovative machinery.
