Archroma announces certification of compostability for range of paper dyes

Pratteln, Switzerland, 1 August 2023 - Archroma, a leading global provider of specialty chemicals and sustainable solutions, announces the certification of a color range of dyes for compostable paper. Colorants from our Carta^®, Cartasol^® F and Cartafix^® range have been meticulously selected to meet the growing demand for environmentally friendlier coloration in the paper industry.

As the paper industry strives to adopt more sustainable practices and minimize its environmental impact, compostable materials have gained considerable attention. Compostability plays a crucial role in the circular economy, enabling waste reduction and the generation of valuable organic matter.

To ensure the safe and efficient composting of paper products, stringent evaluation criteria have been established, encompassing heavy metals and fluorine content, biodegradation, ecotoxicity and plant growth test assessments. Recognizing the importance of meeting these criteria, Archroma has introduced a range of compostable dyes and fixatives for paper applications that fully satisfy these standards set forth.

Archroma's compostable dyes and fixatives for colored paper not only provide exceptional color performance but also meet the most rigorous compostability standards. When applied to compostable materials in a specified concentration of dry weight, our dyes fulfill the evaluation criteria for heavy metals and fluorine, biodegradation, ecotoxicity and plant growth test, as outlined in EN 13432 (2000), NF-T51-800 (2015), ASTM D6400 (2012, 2021), and ISO 17088 (2012).
