The results showed that biochar addition, particularly at 5%, accelerated compost maturation by increasing composting temperatures (> 66 °C), reducing moisture content, and enhancing nitrification. While total nitrogen decreased due to volatilization, biochar helped retain nitrogen more effectively, with an increase in nitrate (NO<sub>3</sub>⁻-N) and a reduction in ammonium (NH<sub>4</sub>⁺-N) and nitrite (NO<sub>2</sub>⁻-N). Total phosphorus (TP) and P<sub>2</sub>O<sub>5</sub> levels also increased, although the direct influence of biochar on phosphorus availability was less conclusive.

This study identifies key barriers hindering CE adoption in India’s T&F industry and proposes strategic interventions to overcome them. A hybrid methodology combining Interpretive Structural Modeling (ISM), Cross-Impact Matrix Multiplication Applied to Classification (MICMAC), and Fuzzy Decision-Making Trial and Evaluation Laboratory (F-DEMATEL) is employed to analyse the interrelationships among barriers. The study identifies limited education and skill, insufficient financial support, and strict government rules and regulations as the most critical driving barriers. Moderate barriers comprise inadequate infrastructure, lack of collaboration, communication, and coordination, lack of incentives, consumer and producer behaviour, and inadequate knowledge about eco-friendly systems. Barriers such as fast fashion culture, absence of cradle-to-cradle (C2C) systems, and lack of modern technological innovation were identified as dependent variables. Addressing these challenges through targeted policy, stakeholder engagement, and capacity building can enhance productivity and profitability while minimizing environmental impact.
