DyStar releases sustainability report
14/09/2022
The added business has led to an increase in impacts in packaging and waste generated (kg per tonne of production) as well as in non-renewable energy intensity.
DyStar has however successfully reduced impact points such as greenhouse gas emissions intensity (tCO2e emitted per tonne of production), water consumption intensity (cubic metre of water consumed per tonne of production) and wastewater production intensity (cubic metre of wastewater per tonne of production). These, the report states, cover Scope 1 and 2 for energy, water, raw materials and GHG emissions but only its owned and operated sites for waste and wastewater generation. The company singled out its greenhouse gas (GHG) emission intensity, which has been reduced by 40%, and wastewater emission intensity, lessened by 37%, both compared to 2011. It also highlighted that 2021 saw “zero workplace fatalities, high-consequence injuries and work-related ill health”.
With regards to denim, the report indicates that DyStar purchases more than 700 raw materials and crude/semi-finish products every year. In FY 2021, the top 20 items purchased included indigo crude, disperse and vat dye press cakes. These raw materials account for approximately 50% of DyStar’s raw material procurements during the year.
DyStar collaborates with the Cradle-to-Cradle Product Innovation Institute and 54 textile dyes have to date been awarded Platinum level C2C Certified Material Health Certificate.
It is seeking to expand the number of customers having implemented its assorted Cadira modules. These, the report states, help save valuable resources by lowering overall carbon footprint, reducing wastewater and quantities of chemicals used. The salt-free Cadira Denim module, it states, leads to 95% less sulfate, a 50% reduction in suspended solids in effluent, 82% lower COD and 10% reduction in wastewater compared to “standard indigo dyeing process using hydrosulphite”.
Eric Hopmann, CEO of DyStar Group commented: “We remain cautiously optimistic about the company’s financial and environmental performance. The integrated value creation model that we began in 2020 has proven to be effective and will continue to support our efforts toward DyStar’s 2025 Sustainability Master Plan.”
