Bangladesh garment manufacturer M&J Group has implemented a new sustainability tool at its facility in Dhaka that measures resource consumption in production, as part of a raft of new environmental innovations.

The Start to Measure tool is one of a number M&J has implemented at its factory this year. The company claims it is the only integrated system engineered to provide scientific rather than subjective data about resource consumption in garment finishing processes.

Three years in development, the tracking system is able to assess the quantity of resources used in the production of a pair of jeans, in particular water, energy, chemicals and labour. 

"Start to Measure sets a new standard for the industry, offering clients the chance to realise the resource consumption impact on their incomes, empowering them to promote a real change of pace towards a saving strategy," the company said. 

Also developed by M&J is BiO3, an eco-finish that reduces waste to oxygen. It allows for the complete elimination of potassium permanganate in the denim finishing process for the production of a vintage look. The process consumes less water and chemicals than traditional wet finishing. 

The ZenZero Polar dyeing technique has also been introduced at M&J's facility, offering both chemical and natural resources savings. The process cuts the average dyeing ratio of 1:10 (kilos of goods to litres of water), down to 1:1. 

"Using less water means reducing the purification procedures in the water treatment plants," the company explains. "Consequentially, in a waterfall model, the reduced use of water implies the reduction of energy consumption, dyeing time (less than 30 minutes) and processing temperature, which decreases from 50-95°C up to room temperature."
