“We have long taken a
precautionary approach to
the environment. This was
the reason we developed and
started to implement our own
global effluent standards in
2011, as we recognised that
simply complying with national
effluent standards was not
enough.
Since then legislative limits
around the world have been
progressively tightening and in
some locations have superseded
our global standards.
Complying with government
standards is always a given for
us, and continues to be a driver
of our investment plans, but
we still believe that wherever
we operate the environment is
equally precious and that we
must therefore apply global
standards to our operations.
For this reason we have now
adopted the Zero Discharge of
Hazardous Chemicals standards
as our global standards. This
allows us to continue to be a
leader within our industry and
to work to a set of commonly
accepted standards that did not
exist in the past.
A huge step forward has also
been the implementation of
online monitoring of effluent
to ensure that our treatment
plants are operating within
limits 100% of the time.”

Effluent and Emissions Strategy
Our long term vision is to cease to use water for dyeing, but there is no technology currently available at industrial level to achieve that goal, so while we continue to use aqueous technology we will have a need to manage our effluent to avoid detrimental impacts on the environment. Since 2011 all of our units have worked to an internal set of effluent standards. These are, in most cases, considerably more stringent than the local requirements. In 2016 we joined the Zero Discharge of Hazardous Chemicals (ZDHC) association as this was gathering momentum across the textile industry with the goal of creating common standards that would be applicable across the whole industry. In 2019 we adopted the ZDHC standards as our standards instead of the Coats standards. Our target is to have all units meeting the ZDHC standards by 2022, and thanks to the work already done over 60% of our effluent was compliant by the end of 2019. Late in 2019 the ZDHC standard was updated to include sludge testing as well as effluent. During 2020 we will be adding sludge testing to our targets and adjusting plans accordingly. Early results indicate that we will have to undertake additional actions to achieve uniform sludge compliance. Ensuring that all of our units are capable of meeting the required limits is important but it is equally important to ensure that effluent treatment plants are working consistently and to ensure this we installed, during 2018, automated measurement systems in all of our key units. These take measurements of core parameters every 30 seconds and issue automated warnings if the systems begin to approach control units. We also piloted, in 2019, a system that automatically shuts off discharge if a standards breach is likely and will install this across other units in 2020.
As a significant user of energy, Green House Gas (GHG) emissions are a key concern for us. Our activities have been described above in the Energy section; reduction of energy usage and transition of energy sourcing to renewables. Our target, will be determined once we have established our renewable energy target in 2020. In 2019 we achieved a reduction of 3% in GHG emissions intensity and a reduction of 5% in absolute GHG emissions compared to 2018 (excluding NA Crafts from 2018 data and including Gotex and Patrick Yarns).
Zero Liquid Discharge at
Ambasamudram
In 2019, we completed the implementation of a very significant Zero
Liquid Discharge (ZLD) system at our largest site in India at Ambasamudram,
Tamil Nadu.
This site consumes approximately 3,500 tonnes of water per day, which
previously was treated and discharged into the environment. To achieve zero
liquid discharge, the existing wastewater treatment plant was modified to
incorporate new cutting-edge technology, including ultrafiltration, reverse
osmosis and multi-effect evaporators. As a result around 95% of the water
entering the treatment plant is returned for reuse in the factory and the
remaining 5% is evaporated to leave a solid waste, which is used as a
cement additive by a local cement company. The steam required for the
new evaporators is generated using biomass, ensuring carbon neutrality
for this process.
In February 2019, we successfully closed down our treated wastewater
discharge channel in a ceremony witnessed by the Tamil Nadu Pollution
Control Board.
