Driven by individual recycling and sustainability targets, as well as by legislation and global public demand for increased sustainability, many brand owners have pledged to increase their use of recycling polymers in their plastic packaging materials over the next five to ten years. Clariant has developed an automated coloration system for rPET that instantly adapts coloration during the production process.
Achieving high-quality rPET to meet recycled packaging targets
Today, there are not enough consistently high-quality rPET grades available in the market, for a variety of reasons. This limits the flexibility brand owners should be able to enjoy to choose appropriate materials that meet their recycling and sustainability targets – and actually increases the cost of those materials. In particular, the color inconsistency of various rPET grades has so far limited brand owners to only a small range of usable products, as light grey or yellowish discoloration of rPET results in inconsistent coloration of PET bottles once they are on the shelf.
Clariant has been cooperating with consumer goods companies to achieve higher recycling rates by developing an automated coloration system for rPET. To make use of food grade rPET packaging material and containers that are slightly discolored, we are developing an automated coloration system for containers which instantly adapts the coloration in the container production, depending on the rPET color. This will increase consumer goods companies’ flexibility in rPET sourcing and help them to achieve recycling targets.
rPET plastic is extremely sustainable as it is produced from recycled PET, making it an ideal choice for packaging and containers. The bottles are shatterproof and light, helping to reduce fuel costs during transport and CO2 emissions. They are safe and hygienic to use for food and beverage packaging.
