Some of our processes, especially dyeing, are intensive users of water. Many of our plants are in areas of water stress.

Ensuring that we are minimising the additional water stress that we are causing through our operations is important to other users and to the environment.


Why is Water Preservation Important?

Water is a precious resource and is coming under increasing pressure globally. Textile manufacturing, and especially dyeing processes, use significant volumes of water. We recognise our responsibility to use water as efficiently as possible to ensure that our water extraction activities create no negative impact on the local communities and biodiversity in the areas in which we operate. We are committed to minimising fresh water abstraction, and commit to reducing water consumption especially in areas of high water stress, and we strive to return the water we have used to the environment in a fit state for use by others.

“23% of our current sites are located in areas of ‘high or extremely high’ baseline water stress, and these sites are given high priority”


We have now set a target to deliver a 33% increase in the rate of water recycling by 2026, based on our 2022 baseline, and will focus on delivering this primarily in our sites located in medium and higher water stress locations. Delivery of this target rate of increase in water recycling will come from investments in reverse osmosis and ultra-filtration systems with capital investments planned for installation of these systems through the 2023 to 2026 time horizon.

Leak Remediation in Sevier


Inclusion of our Sevier site in our global ESG Utilities metering project in 2022, resulted in the installation of numerous smart water flow meters in different locations across the factory, with real-time data streamed into our cloud based Utilities management software. The additional granularity of data enabled the local ESG project team to develop significantly improved insights and understanding on where water losses were occurring across the facility and insight-led actions were planned and implemented to deliver significant water leak remediation, supporting an overall site level water intensity reduction of 29% in 2022 versus 2021.

“Availability and use of streamed data helped our continuous improvement teams quickly develop actionable insights which have underpinned significant reductions in site level water usage”
Emrah Bilgin, US Manufacturing Director

2022 Performance

In 2022, we dyed 3.78 million individual batches and 188 thousand discrete shades across our 36 dyehouse and laboratory operations globally. 89% of our water consumption globally is attributed to sites with dyehouse operations where currently available technology for dyeing of textile substrates is reliant on use of water as the vehicle to carry dyestuff molecules into the fibre to achieve the target colour specified by the brands, retailers and end customers that we serve. Water is also used extensively in wet processing for dyeing pretreatment, where wetting-out of fibres is required; dyeing post treatment, where washes and rinses are applied to optimise colour fastness; and machine cleaning, to eliminate contamination when transitioning from dark to light shades.
Since 2018, our primary metric for water has been water intensity, measured in litres of water per Kg of finished goods produced, with a target set to deliver a 40% reduction in 2022 against our 2018 baseline. In 2022, we delivered a 38% reduction in water intensity against our 2018 baseline, reducing from 85.2 litres water per Kg finished goods production in 2018 to 52.5 litres water per Kg finished goods production in 2022. In the last quarter of the year, through further process optimisation, we delivered and overall 46% reduction in water intensity versus our 2018 baseline. As well as the significant reduction in proportion of water used in our processes, this equates to an absolute annual reduction in water consumption of 1.6 million cubic meters, equivalent to the annual drinking water requirement for 2.2 million people.
The reduction in water intensity has been delivered through a geographically diverse and multi-disciplined team under our Cleaner and Lighter programme with focus on reducing batch liquor ratio, process optimisation to reduce or eliminate washing and rinsing cycles, and in some cases moving process treatments from multiple to single bath processes. Collaborating closely with our trusted supplier network, we have worked on innovative solutions, introducing new dyeing chemistry in some processes to reduce dyeing-related water intensity and to reduce the rate of machine cleaning required to eliminate contamination.
This reduction in water intensity brings with it wider sustainability benefits, with reduced energy requirements for heating the lower quantum of process water, and lower additions of dyeing auxiliary chemicals which are generally added in proportion to the volume of process water.

New Chemistry for Cotton Hank Dyeing in India


Dyeing of cotton with reactive dyestuffs is known to be one of the most water intensive dyeing processes in the textile industry, requiring multiple dye bath fills and drains to deliver the required high brightness shades with the requisite levels of colour fastness. Our team in India identified an opportunity to transition their cotton hank dyeing processes onto new state of the art reactive dyeing technology and in this part of the business has delivered an 44% reduction in water intensity through the course of 2022.


Managing Water Scarcity

Having delivered such significant reductions in water intensity globally from 2018 to 2022, we are now close to the limits for currently available dyeing technology, and in our next target horizon period to 2026 will focus our efforts on increasing the percentage of water recycled from our operations.

As in previous years, using the World Resources Institute Aqueduct Water Risk Tools, we have assessed the overall water supply and demand situation for each of our manufacturing facilities and have classified each based on their location’s water stress with consideration given to water depletion and water table issues.

In 2022, 30% of our water consumption use was in areas with very high or high water stress levels (31% in 2021). A further 33% of our water is used in areas with medium water stress (34% in 2021). Our water recycling investments have previously been prioritised to units with very high water stress levels, where we recycle 42% of our water, compared to 25% globally.

Developing Technologies

In parallel with our work to reduce water use to the minimum and to increase water recycling rates, we continue to invest resources on emerging technologies that will allow us to deliver thread colouration without use of water as our dyeing solvent and heating medium.
In 2018 we invested in Twine, a start-up based in Israel, that is developing digital dyeing technology for yarns. Digital textile dyeing is not a new process, but to date it has only been successfully industrialised for dyeing on fabrics. The challenges of dyeing on yarns and threads are significant when compared to fabric dyeing. Principally the substrate is three dimensional rather than planar and it is microscopic in size compared to a fabric. Twine have successfully addressed these challenges and during 2022 we have continued development work on their technology in one of our Innovation Hubs.

At the United Nations Climate Change Conference of the Parties (COP26) in November 2021, Coats committed to investing US$10m up to 2026 on scaling up the development of green technologies and materials across the industry. In 2023 we will allocate US$2m from this fund to support rollout of the Twine technology at selected apparel and footwear brands to support delivery of high speed, water free sampling.

Recognising that digital dyeing probably won’t be the only disruptive water free technology of the future, we continue to trial other options that may assist us to move away from water-based dyeing.

Water Process

Areas of high or extremely high water stress, as per the WRI definition, are areas where human demand for water exceeds 40% of resources. We have identified that 23% of our businesses’ current sites are located in areas of ‘high or extremely high’ baseline water stress, and these sites are given high priority.

Further details on our water discharge processes can be found under our Waste Pillar where we recognise this as a material issue for stakeholders and continue our commitment to achievement of ‘Zero Discharge of Hazardous Waste’ (ZDHC) effluent standards.

In our 2019-2022 strategy period, our priority focus has been on delivering significant reductions in water intensity, through elimination of wasteful or unnecessary uses, process re-engineering to reduce water use or reduction of the use of chemicals that can lead to degradation of water quality. Having delivered significant progress in this area, our priority will now align to increasing the rate of water recycling across our operations to further reduce “fresh water intensity”. Priority focus for this will be given to high and medium water stress locations as set out by the World Resources Institute Aqueduct Water Risk tools.
