It’s no secret that China is not an environmentally progressive country. Beijing is plagued by air pollution, over 100 cities are facing water scarcity issues, almost a third of China’s rivers are too polluted for human contact, and to top it all off, as a nation China is one of the highest emitters of carbon dioxide.
One of China’s largest polluters are their textile producers. Responsible for roughly 50% of the world’s fabrics, textile manufacturing is a very environmentally un-friendly process that results in high energy and water use. The industry is responsible for the being the third largest dischargers of wastewater and the second largest user of chemicals in China.
All hope is not lost, though. With the help of the National Resources Defense Council’s (NRDC) Clean By Design program, Chinese textile manufacturing facilities are using green tactics to not only reduce energy and water consumption, but also help them save money as well.
The NRDC recently released a report stating that the 33 textile mills that are using the Clean By Design program are saving an estimated $14.7 million annually. By going after the “low-hanging fruit” – the low-cost, easy to implement projects – the textile manufacturers are helping to make a strong business case for sustainability.
Here are some of the ways the Chinese textile mills have not only reduced their environmental impact, but also saved money along the way:
10 of the 33 textile mills went after projects that helped reduce electricity consumption. While the average reduction was only 4%, some of the more impactful projects yielded a 9% reduction with over $21,000 in annual savings. As a bonus, this project paid for itself in only a month!
31 mills implemented 53 projects that resulted in an average of 9% water savings, with some of the top mills reducing water consumption by 20%. A lot of the reuse efforts focused on targeting process water and grey water, because those tended to yield the largest and most cost-effected reductions. Some mills installed a water treatment process, and that initial investment of $7,600 paid for itself in three months.
Through 173 projects that focused on electricity reduction, every participating mill saw an average reduction of 6%, with the top mills seeing a 10% reduction in energy. A majority of the projects saw efforts to recover heat from exhaust gas, water, and oil due to the fact that they produced that largest, most cost-effective reductions: a $500,000 investment yielded roughly $650,000 in annual returns.
