The HolyGrail 2.0 Initiative aims to improve the sorting of plastic waste. But the method also has certain drawbacks. Here, luminescent pigments provide an alternative.

Marker masterbatches enable different information to be embedded in plastics. This can be used to improve the recycling circle.

Recycling: Foaming instead  of Dreaming

The new plant will immediately produce an approximate 18,000 tons per year of recycled material from near-household collection.

At the new plant, the joint venture produces recycled PET granulate based on bottles from household waste for the production of new preforms and bottles.

Revalyu Builds Major Facility in the USA

Each year, more than one million tons of plastic waste are generated in Kenya – so far unused. T3 wants to change this and invests in a bottle-to-bottle recycling plant from Starlinger.

Around 1,334,000 tons of plastic become waste in Kenya each year.

“Nothing Speaks against the Use of Recyclates for Demanding Components”

At its small-scale PET recycling pilot line in Octeville, France, Sidel will develop its understanding of PET recycling with the aim of giving comprehensive support to the market as it switches to greater use of recycled PET.

Sidel opens a new hub to develop design for recycling primary packaging in Octeville, France.

Plastic waste in the sea has been shaping the negative image of the industry for several years. Various initiatives and mergers of companies have therefore launched projects to tackle this Ocean-bound Plastics (OBP). Components made of OBP could become a symbol for a sustainable use of plastics.

The availability of PET bottle flake outside the beverage sector is expected to decline continuously in the coming years. Tray-to-tray recycling can close this gap and succeeds particularly easily with a new extruder.

Research to Improve Recyclate Use

Compensating for Darkening in Recycled PET

The increasing demand for recyclates and the shortage of food-grade PET flakes pose challenges for batch quality and color consistency.

Polyethylene terephthalate (PET) is a model student when it comes to plastics recycling. However, rising demand for recycled materials and shortages of food-grade PET flakes are proving problematic in respect of batch quality and color consistency.

The biggest headache for recyclers and converters is managing the L-value waste. While it is possible to correct the color of rPET with tailored formulations that act on a* and b*, darkening of the material and, more precisely, the reduction in the L* value, are very difficult to avoid.

Italian additives manufacturer Repi offers various additives for the recycling of PET that can serve to improve the quality of the recycled materials. These include additives that compensate for yellowing, increase brightness and gloss, along with chain extenders for increasing the molecular weight and improving mechanical properties. The company claims that the additives can be used at various stages in the rPET value chain, from recycling to preform and tray production, without detriment to the processes.

A new additive is now expected to solve the problem of L-value reduction. Called StabiPlus, this is a liquid formulation that acts as a stabilizer and prevents aging and discoloration of rPET. Repi says that the additive can be used both in mechanical recycling and directly by converters in the production of packaging. This ensures flexible metering. According to the manufacturer, the stabilizer does not affect the intrinsic viscosity or the mechanical properties of rPET. As a result, it widens the window for using recycled PET.
