Abstract: This research paper focuses on the chemical characterization of food waste to explore its potential for nutrient recovery and reuse. Food waste, an increasing global issue, is often viewed as an environmental burden, contributing to greenhouse gas emissions and resource depletion. However, this study highlights the valuable nutrients contained in food waste, which can be recovered and repurposed for various applications, thus contributing to a circular economy. Through detailed chemical analysis, the study reveals that different types of food waste, such as fruit and vegetable peels, grain husks, and dairy residues, retain significant amounts of essential nutrients, including proteins, lipids, carbohydrates, vitamins, and minerals. These findings suggest that food waste, when properly processed, can be transformed into valuable resources for multiple sectors. The study identifies several potential applications for the recovered nutrients. In agriculture, nutrients can be repurposed as organic fertilizers or soil conditioners, enhancing soil fertility and reducing the need for synthetic fertilizers. This not only promotes sustainable farming practices but also mitigates environmental issues such as soil degradation and water pollution. In the industrial sector, recovered proteins and lipids from food waste can be used in the production of bio-based materials, such as bioplastics and biofuels, offering eco-friendly alternatives to petroleum-based products. Additionally, bioactive compounds recovered from food waste can be utilized in the pharmaceutical and nutraceutical industries, contributing to the development of functional foods and dietary supplements. The research also discusses the implications of nutrient recovery for waste management practices, emphasizing the importance of shifting from waste disposal to resource recovery. However, challenges such as variability in food waste composition, economic feasibility, and regulatory barriers must be addressed to fully realize the potential of nutrient recovery. The study calls for further research into advanced nutrient recovery technologies and supportive policies to promote sustainable waste management. In conclusion, this paper underscores the significant potential of food waste as a resource for nutrient recovery and reuse, offering a pathway towards more sustainable and circular food systems. By harnessing the nutrients in food waste, society can reduce environmental impacts, conserve resources, and support the transition to a more sustainable future.
