US Denim is continuously implementing new waterless methods:
- Our range of machines save water and control effluents. As well, we can now bleach and change cast without using chemicals.
- We’re finding way to preserve water in our finishing processes, too. So far we have converted 117 finishes to waterless recipes, saving approximately 140-thousand cubic meters of water just this year. We expect to convert 80 percent of our recipes by the end of next year.
- We are also re-using the waste water that still gets produced, for cleaning and for horticulture. And we’re developing proposals for a whole water recycling plant.
- To reduce the use of hazardous chemicals in the supply chain, we have a dedicated Technical Representative for chemical management. We always purchase chemicals from approved chemical suppliers with all the compliance documents like PSD, CIL, SDS, COA and TDS. We can ensure we always use the chemicals and dyes that are in compliance with your own Restricted Substances List.
- We’re also partnering to identify and implement new chemical processes that don’t harm the environment, and already using a number of Garmon and DyStar products that are GreenScreen Chemistry. GreenScreen provides a scientific open-source, transparent assessment of a chemical’s potential hazards; gives the industry a consistent, unbiased standard, and makes restricted substance lists more transparent; and lets consumers have the information they need to know in order to make sustainable choices.
We’re also investing in other ways to limit the resources needed for your jeans.
- We operate our boilers with local biofuels rather than conventional energy resources. And we’re saving more energy using waste-heat recovery.
- We’re moving from conventional lights toward energy efficient LED tube lights. So far, switching 1000 tubes has is saving us 20-kilowatt hours per month, and we’re about to quadruple that amount.
- Switching to more efficient motors and electronic ballast systems has reduced power consumption by another half million kilowatt hours per year.
- We’ve installed 30 kilowatts of solar power, and will soon expand that to 150 kilowatts.
- Our next factory, called US-five, is now being designed for LEED certification.
- And we’re now finding other equipment that will allow us to be more sustainable, such as eliminating the use of Potassium Permanganate in distressing by replacing it with water canon technology.
