The Centre for Science and Environment (CSE) conducted a study to evaluate the quality of compost produced across 23 different sites in the states of Haryana, Uttar Pradesh and Odisha. The composting sites employed various technologies such as tub composting, organic waste converter, pit composting, windrow composting, and AAGA aerobic tub composting.

This study aims to evaluate the composting processes and identify potential areas for improvement. Key highlights of results include the importance of maintaining an optimal carbon-to-nitrogen ratio, addressing heavy metal contamination, and reducing microbial load. The report provides valuable insights for maintaining the quality of compost. It emphasizes the need for improved practices to reduce pathogens and heavy metal contamination. The major recommendations include effective compost drying to reduce moisture and microorganisms and segregating input waste materials to enhance the safety and effectiveness of compost products, contributing to sustainable agriculture and soil health.
