Climate implications of water-free dyeing of biofibers (ClimaDYE)

Rapport, 2017

This document illustrates the project outputs of the Climate-KIC funded project “ClimaDYE”. The purpose of the project is to estimate environmental and in particular climate implications of a water-free dyeing technology using supercritical CO2 (scCO2) and to evaluate the business case for it. The outputs of the ClimaDYE project are three: 1. an economic and environmental evaluation of scCO2 dyeing of polyester (PES) fabric against two alternative dyeing technologies 2. an estimation of environmental impact of scCO2 dyeing of biofibers, to be confirmed by future physical tests on biofibers 3. a list of business opportunities for PES and biofibers dyeing with scCO2, to be confirmed by future physical tests on biofibers. As a result, this deliverable is to be considered as a blend of a feasibility study and a comparative study. This document contains the main analyses being done to obtain the project outputs mentioned above, and the project results in relation to the three outputs.
