 This study investigated the barriers to sustainable boiler operations in the apparel manufacturing industry in Bangladesh. The study found that the absence of water treatment facilities, fossil fuel burning and greenhouse gas emissions, and excessive consumption of groundwater are the top three barriers to sustainable boiler operations. Additionally, the study found that inadequate compliance with safety and hazard regulations was the most influential factor in causing these barriers, while fossil fuel burning and greenhouse gas emissions was the most influenced barrier. The study concluded that the apparel manufacturers should focus on improving their compliance with safety and hazard regulations, as well as investing in water treatment facilities and renewable energy sources to reduce fossil fuel burning and greenhouse gas emissions.
