For tanners, reducing the effluent load and resource consumption is an industry top priority. Not just for the sake of meeting legislative requirements, but also to comply with universally growing ecological awareness. The beamhouse and tanning process accounts for 70% of the wastewater and solid waste from the production process. Stahl BeTan® offers a technical solution for tanners who aim to apply higher ecological standards.
Towards a more sustainable tanning process with BeTan®
There are a number of essential steps to be undertaken for tannery processes to achieve a more positive environmental footprint:
- Reducing water consumption, liquid and solid waste.
- Reducing chemical and biological oxygen demand (COD and BOD)
- Reducing the use of hazardous chemical compounds like chromium, sulfide and nitrogen
Conventional tanning processes often rely heavily on bactericides, surfactants, and chemicals such as sulfide, amine, and ammonium salts. These substances contribute to the issues mentioned earlier. However, the Stahl BeTan® portfolio offers innovative tanning technologies that provide alternative methods to eliminate or reduce the need for harmful compounds like heavy metals, nitrogen, and sulfides. By embracing these alternative methods, tanners can make significant progress in creating a more sustainable and environmentally friendly tanning process.
Responsible quality leathers
By incorporating the environmentally friendly technologies of the ZDHC MRSL compliant Stahl BeTan® portfolio, tanners can effectively reduce their water, salt, and chemical usage. These cost-effective innovations not only save time and energy, but also minimize waste by reducing the presence of solids in the process. Furthermore, they successfully address common challenges such as wrinkles, hair roots, stains, odors, and VOCs. To gain a comprehensive understanding of the advantages and technologies offered in this new portfolio for every step of the tanning process, including auxiliary processes like soaking, you can access the downloadable whitepaper provided below this article.
