Abstract

This research explores the conversion of municipal food waste into biochar, a nutrient-rich organic soil amendment using pyrolysis at varying temperatures (300°C, 450°C, and 600°C). The study demonstrates that biochar produced at moderate temperatures enhances soil quality, supports plant growth, and reduces reliance on chemical fertilizers. The findings show that biochar retains essential nutrients such as nitrogen, calcium, and potassium, making it an eco-friendly organic fertilizer. Additionally, this approach provides an effective waste management solution, reducing greenhouse gas emissions and landfill waste.
