The CurCol project, in which partners from Ireland, Germany, Belgium and the Netherlands worked together, conducted research to the potential of Curcumin as a natural dye. The CurCol project is an important step towards sustainable packaging and materials. The production of turmeric-based dyes with improved quality and suitability for use in plastic packaging and inks is possible. It is a natural alternative to synthetic dyes. The project is an inspiration for other companies in the industry to also work on sustainability and hopefully encourages end users and retailers so that natural dyes can enter the market. This will contribute to a greener future for Europe and the rest of the world. Read More
An increasing amount of biobased and biodegradable articles is being designed and used. However many aspects of the research are still neglected, which can have a serious impact on the environment! The aim of this presentation is to inform product designers about their choice of colorant in biobased and biodegradable plastics. Read More
Strategies to overcome curcumin's poor biodegradability: Investigation of the chemical and biological stability of curcumin and its derivatives. Read More
Further research has been done by Avans Hogeschool / CoEBBE to synthesize red color derivatives of curcumin. During the first phase of this investigation, several variants have successfully been synthesized at lab scale amounts and proven with analyses. Read More
The first steps have been made into looking at the downstream processing of crude extracts. Initial results indicate that a crude extract made with ethyl acetate results in an end product with a curcuminoid purity of roughly 38%. Read More
The best color stability is reached when using the modified curcumine additives, as produced by Avans Hogeschool. Samples were aged behind a window and it seemed that after 1 year, all non-modified curcumine samples colored brown to dark orange. In case the modified variants were used, the yellow color was maintained, but the saturation of the color diminished. Read More
An article titled “Sustainability assessment of curcumin as a natural colorant” is prepared as an outcome of the cooperation between different project partners. This work evaluates the sustainability of curcumin by taking into account different life cycle phases namely; extraction and purification, processing, use and end of life. Read More
Investigation of the biodegradability of the colorants derived from the CurCol project is a major factor for sustainability. To achieve an overview of how the colorants are biodegraded and which intermediates are formed, a closer look at the whole degradation pathway is helpful. Therefore, partners from the University of Münster are looking at the microbial degradation of the natural colorant curcumin as a proof of principle. Read More
In the context of the Interreg Northwest Europe project CurCol, PCG investigates the regional cultivation of the turmeric plant for coloring purposes. On April 21 2021 pregerminated turmeric rhizomes were planted in a greenhouse in Kruisem, Flanders at the headquarters of PCG (Proefcentrum voor Groenteteelt). The object of this trial was to obtain a more uniform and qualitative yield than the first trial in 2020. Read More
