Composting is an eco-friendly way to manage biodegradable waste, which makes up almost half of municipal solid waste (MSW), and can be improved by adding char from MSW pyrolysis.
The study tested different amounts of MSW char (0%, 2.5%, and 5%) on vegetable waste compost, revealing that higher char levels led to better thermophilic temperatures, nutrient availability, and overall compost quality.
The results showed significant improvements in nutrient concentrations and reductions in volatile solids and heavy metals, especially with 5% char, demonstrating that using MSW char in composting enhances sustainability in waste management.
