PaCT Decision Support Guidance: More Sustainable Wet Processing of Lightweight Knits / Jersey and Denim


Guidance for brands/retailers on influencing environmental performance for wet-processing mills. May also be useful to mills looking to understand the impacts of processes & alternative processes (substitutions), and considerations to reduce the harmful impact in which these processes can result.

Target Audience:  Brands/Retailers, Textile Mills, Suppliers
What will this resource help with?  As a tool to guide decision-making, the DSG has been designed to address the needs of various people on the brand/retailer side who are able to influence the ultimate sustainability of the product. May serve as a resource to mills to establish protocols for certain processes and to support implementation of more positive alternative processes and considerations to reduce impact. 

The Decision Support Guidance (DSG) aims to provide guidance on how a brand can positively influence environmental aspects of textile wet processing through:
1. supply chain management and sourcing decisions and
2. incorporating environmental considerations in product design and development.

PaCT acknowledges that collaboration with suppliers in the identification and implementation of improvement options is key to addressing sustainability concerns, including but not limited to wastewater concerns. PaCT therefore today works with more than 140 wet processing facilities, the majority of which are nominated by the 8 PaCT partner brands. If all stakeholders play a role towards ensuring that dye-houses measure and properly manage their water, energy and chemical usage and treat their effluent, the Bangladesh sector and community will benefit tremendously. Today, brands are particularly powerful players who can ensure that proper environmental management becomes a precondition to doing business sooner rather than later.


The advice within this manual is to spark dialogue on sustainability, promoting more sustainable processing techniques that have been developed over the past years. Sharing this knowledge with supply chain partners, and together support one another in achieving continuous improvement of wet processing.


The DSG is focusing on the key product categories for which textile wet processing takes place in Bangladesh in large volumes: dyeing and finishing of circular knit fabric, and denim finishing.


DSG provides information on sustainability concerns, water, energy, and chemical intensiveness, as well as occupational health and safety (OHS) and effluent considerations for a selection of common wet processing techniques. It furthermore includes specific advice on decisions or actions those in the design/ product development, sourcing/buying, and QA/fabric management roles can make to influence sustainability.


The advice is tailored to each role’s sphere of influence. The advice contained within the DSG is based on first-hand experience (in PaCT), publically available information and expert opinions. The starting points and outline of the DSG has been developed in consultation with PaCT partners. The DSG itself has been reviewed by subject matter experts and after that by PaCT partners to evaluate
usability. A number of assumptions and generalisations are contained within this document. Section 5 on ‘Limitations’ outlines the relevant challenges, variables and limitations.
