| Abstract |
Food waste contributes to hunger, poverty, and environmental pollution. Unfortunately, seafood, which provides high nutrient content, is significantly underutilized, with only 30% of high-value seafood consumed. This study addresses the urgent need to reuse these wastes, converting them into biofertilizers through solar drying. A solar drying plant was designed and built to produce fish powder as the base of fertilizer, achieving an equilibrium humidity of 400 kg in 11 h after sterilization by pre-cooking. The resulting biofertilizer was rigorously tested for its macronutrient composition, germination rate, presence of coliforms, and phytotoxicity. The findings indicate that fish waste can effectively replace synthetic fertilizers, fostering a circular economy and promoting sustainable agriculture. This research highlights the potential of using marine debris to produce biofertilizers, contributing to global sustainability efforts by harnessing marine debris and solar energy to offer an environmentally friendly alternative to chemical fertilizers. |
