Update of the ZDHC MMCF Guidelines 2.0

January, 3rd, ZDHC announced the release of the updated ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines Version 2.0, and its supporting document. By publishing these documents the industry shall be pushed forward increasingly innovative and sustainable fibre production.

The ZDHC MMCF Guidelines V2.0 now include the Responsible Fibre Production Guidelines, Wastewater Guidelines and Air Emissions Guidelines as three separate chapters in a single document.

Fibres are key components of production processes in the textile and fashion value chain and it is crucial to reduce the environmental impact of their manufacture. ZDHC guidelines give suppliers producing MMCF unified criteria for measuring output indicators like wastewater, sludge, air emissions and other process-related parameters.

ZDHC guidelines give suppliers producing MMCF unified criteria for measuring output indicators like wastewater, sludge, air emissions and other process-related parameters.

Among other changes, this update reflects the expansion of the scope to accommodate Viscose Filament Yarn, Lyocell, Cuprammonium Rayon (Cupro) and Cellulose Acetate (Acetate). The ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines V2.0 provide an aligned approach for included fibres, including defined chemical recovery, wastewater and sludge discharge, and air emission discharge.

ZDHC continues to advocate for the improvement of processes which minimise emissions while also working towards the recovery of input substances and by-products. These dual goals, reduction and recovery, directly address the negative impact of outputs arising from MMCF production.

ZDHC MMCF Guidelines Industry Standard Implementation Approach Version 2.0: Additional Industry Support for Implementation
Along with the ZDHC Man-Made Cellulosic Fibres (MMCF) Guidelines V2.0, ZDHC has also updated its ZDHC MMCF Guidelines Industry Standard Implementation Approach. This document aims to support the implementation process of the ZDHC MMCF Guidelines V2.0, and features new implementation timelines that assist suppliers in setting their goals to achieve Foundational, Progressive or Aspirational Level on the ZDHC Supplier Platform.

Lenzing invests GBP 20 mn in wastewater treatment at Grimsby site

  • Full utilization of production capacity possible at the site
  • New EU environmental requirements will be fully and promptly satisfied starting in 2024

The Lenzing Group, a global provider of wood-based specialty fibers for the textile and nonwoven industries, is investing GBP 20 mn (equal to EUR 23.3 mn) to build a new, state-of-the-art wastewater treatment plant at its site in Grimsby, United Kingdom. The investment is part of the company’s plans to reduce wastewater emissions by 2022.

Once it has implemented this project, Lenzing will have biological wastewater treatment plants that meet the best available techniques (BAT) quality standard at all its production sites. The plant design, which will employ a new technology developed as part of a research project, is fully aligned with the UK regulator and supported by the local authorities.

The plant design, which will employ a new technology developed as part of a research project, is fully aligned with the UK regulator and supported by the local authorities.

The site’s current wastewater situation complies fully with the EU Water Framework Directive as well as all local laws and regulations. The investment has been approved by the Supervisory Board, ensuring that construction can start this year and the plant will be commissioned well before the UK-ratified EU directive1 goes into effect. This will be the largest investment since opening this lyocell site, which manufactures premium products for technical and innovative market segments, among other things.

Responsible water use
After modernizing the wastewater treatment plant at the company’s Purwakarta site in Indonesia, the construction of the new plant in Grimsby marks another big step toward reducing the Group’s wastewater emissions 20 percent by 2022 (against a 2014 baseline). Responsible water use is one of the core elements of Lenzing’s “Naturally positive” sustainability strategy and is largely executed by using water efficiently in manufacturing and employing state-of-the-art water treatment technologies.

Koch Membrane Systems PURON® MBR Product Selected for one of the Largest MBR Projects in China

Koch Membrane Systems, Inc. (Koch), a global leader in membrane filtration technologies, announced its PURON® Membrane Bio-Reactor (MBR) modules have been selected for the Ji’nan Wastewater Treatment Plant I and Plant II Expansion Project. Each plant will have 100,000 m3/day treating capacity. The site is located in the Shandong province, which is China’s second-most populated province, with over 100 million people. This project continues the strong presence of Koch’s PURON® MBR in various municipal and industrial wastewater treatment projects in China, demonstrating exceptional performance and creating value to clients.

Strict new discharge requirements by the Chinese government are forcing municipalities to upgrade or build their wastewater treatment plants using new technologies. PURON® MBR technology was selected for these two new plants for its reliable and consistent effluent quality, adherence to new discharge limits, and reduced footprint compared to conventional wastewater treatment technology.

Strict new discharge requirements by the Chinese government are forcing municipalities to upgrade or build their wastewater treatment plants using new technologies. PURON® MBR technology was selected for these two new plants for its reliable and consistent effluent quality, adherence to new discharge limits, and reduced footprint compared to conventional wastewater treatment technology.

These wastewater treatment plants will be built and operated by China Everbright Water Limited Co. Ltd, a company principally engaged in construction and operation of integrated environmental water services. The project is expected to be commissioned by the end of 2018.

“We have had good experience with Koch Membrane Systems PURON® MBR technology in the 55,000 m3/day Beijing Daxing Tiantanghe Waste Water Treatment Project,” said Mr. Wang Huailin, president of Jiangsu Kaimi Membrane Technology Co. Ltd, who will design, build and supply the membrane system for these plants. “Since the 2016 Beijing plant startup, the PURON® membranes have been used in an underground construction model to provide a pollution-free installation. We have been impressed with the low fouling and low operating costs from the PURON® product, due to its unique single header and central aeration design features and the process expertise Koch brings to the table.”

“Koch has developed advanced membrane solutions for the municipal and industrial market segments,” said Mr. Manny Singh, president of Koch Membrane Systems. “Unique features of our PURON® product help the market treat wastewater to meet strict discharge and reuse targets with a low cost of ownership. We are excited that Everbright Water Group recognized the benefits of our PURON® product in their existing plant and selected us for their flagship new projects.”
