With an aim to help in cost reduction for Bangladesh textile industry, ‘ZDHC seminar 2018’ was organized on 4 July in Dhaka, Bangladesh. The seminar was arranged by Evershine Enterprise in collaboration with the Everlight Chemical Industrial Corporation (Taiwan) at Hotel Le Meridian. ‘ZDHC Seminar 2018’ has covered current sustainability topics in the context of Bangladesh’s textile wet processing industry with the aim to raise awareness and inform end-users on Everlight’s firm commitment regarding the implementation of sustainable chemistry and best practices in the textile and leather industries to protect consumers, workers, and the environment.

While speaking at the seminar Amy Huang, Deputy Head, SH Division, Product Stewardship of Everlight, said, “Actually we have to think about the total solution. From purchasing chemical to wastewater treatment, we have to think about the reduction of cost. We have to think about every stage. If you have to control the cost, you have to find the right chemical recipe or the right dye range in the beginning. If you can choose the correct chemical compared to the conventional one, you can use less dye, less wastewater, less CO2 emissions. Then the wastewater treatment process will be easier. As a result, the total cost will be lower than the conventional one.”

Shazid Rahman, Director, Evershine Enterprise said that on behalf of Evershine they are very proud to have Everlight as one of their partners. He also said that they are representing them since 1993. Everlight has been firmly committed towards the goal of zero discharge of hazardous chemicals. Sales Manager of the Sales team David Lu, who is in-charge of Bangladesh market since 2004, presented Everlight to the guests. He said, “Bangladesh textile business has become big at this moment. However, the textile business means dyes, chemicals, and auxiliaries, which destroy the environment, which is not only affecting us but also the next generation. Therefore, this is the perfect time to think about the pollutions.”

“By using the better quality product, we can save our environment. As Everlight is the first dyestuff company to join ZDHC as an associate member, they are producing high quality and eco-friendly product,” he added.

Everlight Chemical was founded in 1972. Its revenue was $307 mn in 2017. Everlight has their market in 17 locations worldwide. “The business we started from colorant, right now we have 5 business units, and these are Color Chemicals, Light Stabilizers, Electronic Chemicals, Pharmaceutical Chemicals, and Tone. But the main business is the color chemical,” said Amy Huang. Around 5 per cent of their revenue goes for R&D to improve their product. They have 250 researchers who are engaged with the research work. Everlight was awarded several times, which shows that Everlight is not only focused on business profit but also consider its social responsibility.

Amy Huang explained how they overcome the challenges they face during the chemical manufacturing process. She said, “We introduced material flow cost accounting (MFCA) tool to help us reduce costs and increase profits while achieving energy saving and carbon reduction, reducing negative products, and improving atomic utilization and competitiveness. We calculate the atomic utilization of chemicals we use and chemicals coming out. When we design a new product, we use ‘12 green chemistry principles’ concept.”

Everlight’s solution for the textile industry

“Everlight has the capability to offer top quality of colorant in the textile industry. We promptly deliver the product to our customers. We also offer a reasonable price. We also developed a lot of green product such as Everzol ED, a strong chromo fore where smaller quantities of dyes required than conventional dyes. We also developed digital textile printing for injecting ink. We also have a fewer product without DMF solvent,” Amy Huang said these while describing their contribution to the textile industry.

Recently Everlight is trying to make their product free from PCA content, which is mainly coming from the reactive black mixture. Almost all black colour contain PCA (para Chloroaniline), Everlight has products to overcome these problems, such as Everzol Black series (PCA content <150ppm), Everzol Black ECO series (PCA content <50ppm), Everzol Black PF series (PCA content <5ppm). Highlighting their latest products she said, “We have new product Everzol® PFED-G/ ED-R, ED-3R to the market. Secondly, we have a new product Everacid Black XBW. This new product has high bear up, very little wastewater and the CO2 emission is quite low compared to the previous conventional products for nylon. We are working on the leather also.”

David Lu said, “Everzol® CS is the best solution for Critical Color Shades that dyes with good performance and lightfastness. It is environmentally aware for achieving a better Carbon Footprint.”

Amy Huang discussed the developments, initiatives, regulations, and activities of ZDHC. She highlighted that how collective action can transform an industry. He said that Everlight wants to give ‘Green Solutions’ for apparel and footwear. It also wants to reduce heavy metal item from their chemicals. They have new black acid item Everacid Black X-BW for nylon and wool. By using these dyes, one can reduce the use of dyestuff usage up to 41 per cent and X-BW present two times stronger strength than the traditional one. The removal of Cr removal rate is also remarkable for this product than the previous conventional one.“The vision of ZDHC is widespread implementation of sustainable chemistry and best practices in the textile, leather and footwear industries to protect consumers, workers, and the environment,” she said.

Some products of Everlight: Everzol Black series, Everzol® CS, Evereco® PUR Adhesive, Eversolar® DSSC, Eversorb® Light Stabilizer, Everlight Chemical Anti- Glaucoma API series, Everacid Black X-BW, Everjet® RT &AT, EverzolED.

The ZDHC Roadmap to Zero Programme takes a holistic approach to tackle the issue of hazardous chemicals in the global textile, leather and footwear value chain. Their goal is to eliminate the use of priority hazardous chemicals by focusing on the following areas:

• Manufacturing Restricted Substances List (MRSL) & Conformity Guidance
• Wastewater Quality, Audit Protocol, Research
• Data and Disclosure • Training

The ZDHC Wastewater Guidelines, which go beyond regulatory compliance, are designed to ensure the discharge of treated wastewater does not adversely affect the environment and surrounding communities.

The ZDHC Gateway – Wastewater Module is a global webbased platform that is designed to share verified wastewater and sludge test data based on testing against the ZDHC Wastewater Guidelines.

“It provides suppliers (manufacturing facilities) with an easy way to disclose secured and verified wastewater and sludge data to their clients (brands/retailers), reduce the number of unnecessary testing and instead focuses on improving the quality of discharge,” said Amy Huang. “Everlight Chemical has become a ZDHC associate member and committed to ZDHC 2020 Joint Roadmap as we have recognised the urgent need to eliminate the industrial releases of hazardous chemicals into the environment,” she said.

She also mentioned that in line with the content of the Joint Roadmap and according to our approach in support of the Precautionary principle, Everlight Chemical fully acknowledges and understands the seriousness of the problem of hazardous chemicals and is committed to the goal of zero discharge of hazardous chemicals for all its products across all pathways of release (discharges, emissions and losses) in our supply chains (with a full life-cycle perspective) by 2020.
