The garment industry, one of Bangladesh’s largest economic sectors, generates a substantial number of solid wastes, particularly fabric scraps known locally as “jhute”. Improper management and poor disposal of these wastes have resulted in serious environmental challenges. The challenges include the rise of Green House Gas emissions, which contribute to global warming. The present paper evaluates the solid waste management practices in selected garment factories in urban and peri-urban Dhaka, the capital of Bangladesh. The paper aims to focus on the environmental impacts and carbon footprint of the garment factories. Adopting the Organizational Carbon Footprint (OCF) approach using a gate-to-grave system boundary that falls under Scope 3, Category 5 Waste Generated in Operations - GHG Protocol, the study evaluates the emission factor-based estimation for three common disposal methods: recycling, incineration and landfilling. The estimated carbon emissions show that recycling produces the lowest emissions of 252.3 kg CO₂e, whereas landfilling and incineration generate emissions with an approximation of 790.2 kg CO₂e and 886.8 kg CO₂e, respectively, indicating that recycling is the most viable and carbon efficient method of disposing garment waste. The calculated values reflect indirect emissions from the overall waste-disposal process, based solely on the mass of waste generated and disposed. The findings suggest improvement of domestic recycling capacity, formalization of the jhute sector and incentives for low-carbon waste policies. With proper validation of the findings, strengthening the waste management infrastructure and promoting greener industry practices would assist the garment sector move towards a more circular, low-carbon and environmentally responsible future.
