Food waste is a pressing global challenge, particularly in developing countries, where it not only exacerbates food insecurity but also imposes significant economic and environmental burdens. Effective solutions are urgently required to minimize waste and its associated impacts. One innovative approach is the valorization of fruit waste, transforming discarded materials into valuable products like metal oxide nanoparticles. This project addresses a critical gap in the valorization of fruit waste in Arunachal Pradesh by applying cutting-edge nanotechnology to local resources. It combines waste reduction, food preservation, and sustainability, leveraging the region’s biodiversity to develop innovative solutions. Globally, food waste is a pressing issue, with one-third of all food produced—approximately 1.3 billion tons—being lost or wasted annually (FAO, 2021). This waste not only causes economic losses but also contributes to environmental problems such as greenhouse gas emissions and resource depletion. Traditional food packaging, predominantly plastic-based, further exacerbates these challenges due to its non-biodegradability. The proposed project offers a dual-purpose solution by addressing food spoilage and packaging waste through nanotechnology. Metal oxide nanoparticles like zinc oxide (ZnO), synthesized via environmentally friendly green methods, are integrated into biodegradable polymer-based packaging materials. These advanced materials exhibit antimicrobial, antioxidant, and barrier properties that extend the shelf life of perishable foods, reduce food loss, and minimize plastic pollution. India’s agricultural sector, vital to its economy, suffers from substantial postharvest losses due to inadequate storage, transportation, and packaging systems. Fruit waste, in particular, remains underutilized. Regions such as Arunachal Pradesh, which produce large quantities of fruits like oranges, pineapples, and kiwis, generate significant waste due to seasonal production and limited value-addition facilities. This project transforms this underutilized resource into high-value materials, contributing to a circular economy. Government initiatives like the Waste to Wealth Mission and the National Biodegradable Packaging Policy highlight the importance of integrating waste management with sustainable material development. The project aligns with these policies by reducing postharvest losses, enhancing the quality of food packaging, and lowering environmental impacts through the adoption of green technologies.
