Characterization of composting process and chemical composition of compost from recycling centers in Surabaya City, Indonesia

Urban Farm DB summary

This study in Surabaya City, Indonesia, used a qualitative descriptive approach to characterize the composting process and compost from recycling centers. Composting materials included household waste, market refuse, and fall foliage, processed in an open aerobic system without bio-activators. Chemical analysis showed C/N ratio (17.10-19.60), C-total (17.65%-18.10%), and N-total (0.95%-1.12%), among other elements. While visually mature, indicators such as C/N ratio and temperature suggested an immature state, rendering the compost unsuitable for immediate planting; storage for a minimum of one month was recommended for maturation.
