Denim is a fast growing industry in Bangladesh and Envoy Textiles Limited (ETL) is a renowned and leading denim factory of the country. The factory is practicing sustainability in a different way and it is the first denim mill with rope dyeing technology in Bangladesh, received -2017 HSBC Sustainable Award.
Sustainable Development Initiatives at ETL
1) Commitment to Sustainable Denim Development
Envoy is the 1st LEED Platinum Certified denim factory in the world. It addresses total and holistic ecosystem from the raw materials to finished products as well as it addresses the holistic approach to total ecosystem under its own operational area with stringent practice, incremental investment in machinery consuming less water and generate less Green House Gas (GHG), landscaping, ecological sustainability, sustainable and quality food chain for better health assurance for its workforce and best water use within its area.
Our raw material is cotton, chemical, water, and energy mainly. But in each case, we ensure the best practice from the bottom -up.
Our cotton comes from sources complying BCI (Better Cotton Initiative), OEKOTEX appendix-6 (finer), GOTS (Global Organic Textiles Standards) and CMIA. And we are going to complete the total procedure to ensure GRS and RCS certifications. This is our first stage of raw materials input where we have tried to ensure every possible standard. Moreover, we have successfully implemented “YESS” (Yearn Ethically Sustainable Sourcing). 71% of our cotton comes from sustainable material responsible sourcing.
Our commitment to the quality product never goes unnoticed. Now ETL has become the contributor of ZDHC and committed to DETOX platform. These have ensured the green rated chemicals usage in the process that has admitted the level of impact on the environment and free of toxic chemicals in the product. So, in PURE project launched by GIZ, Germany and LIDL ETL achieved the highest Number in Bangladesh for Chemical Management after stringent evaluation of our chemical handling practices within our factory. Eventually, GREEN PEACE came to our factory to witness the extraordinary practices in the Environmental Management System (EMS) that becomes the part of our culture.
The Company has installed highly efficient and cost-effective biochemical ETP plant considering the water and energy sustainability aspects compared to other methods.
The leadership of Envoy Textiles Limited for the Inception has ensured capital investment in the best possible echo-friendly machines and equipment. The thrive for the best possible process machines and Environment concern practices gave Envoy Textiles Limited a prestigious position in the world. Due to the best possible setup in Utility machines and equipment, it secured LEED PLATINUM as a first in the world. It secured the 3rd position from CPI 2 in carbon emission performance in the world. We secured one of the best scores in Higg Index 3.0 in Bangladesh. ETL is the first textile Factory in Bangladesh that has upgraded itself with ISO 9001: 2015 and ISO 14001: 2015 certification in the country.
2) Effluent Treatment Plant (ETP)
ETL has established an ETP which runs round the clock to ensure that “zero discharges” are taking place in nature. Periodic chemical tests and other regulatory tests are also happening to ensure the quality of the discharged water is not harmful to nature.
3) Co-Generation of Power/Energy
Generally generator exhausts are discharged in the air as a waste product but they have taken an initiative to use this exhaust as an input for further energy generation. These exhausts are used as a heat source for boiler and chiller. Thus ETL is re-using almost 70% of the waste product with this Co-Generation concept.
4) Rain Water Harvesting
Rainwater of ETL are streamed towards an in-house lake and works as a resource for a fire hydrant and also as a source for toilet flash. ETL also build a separate plumbing system to use the lake water toilet flash.
5) Fish Cultivation
ETL cultivates more than 6 types of fishes in the in-house lake which sometimes also works as a source for food and on the other hand works as a site for angling competition.
6) Eco Park/Pond
ETL has an eco-park and pond within the factory premises with rabbits and duck. More species (like deer etc.) are in the process to come.
7) Energy Efficient Building
Most of ETL’s factory shades are made with pre-fabricated reusable material and are designed in such a manner that natural lights can be used to the optimum level.
8) Scenic open space
Overall factory layout of ETL is designed with scenic landscaping and a substantial number of trees, plants etc. are in place to give a greenery look.
9) Employee welfare & CSR
ETL has established a pediatric ICU for burn injury at Dhaka Medical College Hospital (DMCH). For the welfare of employees, ETL is doing everything for their betterment.
Tauhidul Islam, Senior Manager, Compliance, said, “The Company has installed highly efficient and cost-effective biochemical ETP plant considering the water and energy sustainability aspects compared to other methods because of least operation and maintenance cost due to very low chemical consumption, low labor cost, less sludge treatment, and disposal cost as well as eco-friendly.”
“Instead of fluorescent light, ETL installed LED light, which saves 3% electricity cost. Moreover, we are saving 29% light energy by installing a transparent sheet on top of our production floor. In addition, to reuse the heat energy, we are using condensing recovery pump, Co-Generation system, VFD Compressor, which is remarkable,” he continued.
“For water reduction, we use the lake for rainwater harvesting and over 30 million liters of water can be stored. Above 80% green chemicals are used at ETL,” he concluded.
Compared to the conventional denim dyeing process, it saves up to: 92% water, 87% cotton waste, 30% energy.
Ozone technology is another term for sustainability which is applied in fabric processing. Save 40-50% water during fabric processing, reduce electricity consumption and reduce the use of chemicals.
Caustic soda is recovered, reduced chemical consumption for ETP neutralization, generation of hot water as a by-product, short payback.
To avoid the effects of the hazardous chemical on the environment, they follow the international chemical mixing guideline strictly. And wearing safety equipment’s is a must for the workers.
As part of their sustainability practice, they arrange weekly meetings, in-house training to increase the awareness of the employees by using different innovative tools and means.
