A growing number of companies and industrial sectors would like to use recyclates for their products. However, the application is frequently still confronted with considerable difficulties. And the extension of recycling to other fields and sectors also poses new questions. An overview of the current status and associated technical solutions was provided in conference “Forum Plastic Recyclates” at the end of March.

Statutory recyclate quotas and the specifications of brand-name producers are weighing heavily on the packaging branch these days and turning recyclate availability into a hot issue. Some polymers are simply not available in sufficient amounts. Experts at the 31st Dresden Packaging Conference provided insights into the current situations and explained why the situation could worsen in the future.

Recyclates of many polymer types are hard to get right now.

Hard-to-Find Recylates

Electrical and electronics manufacturers want to reduce greenhouse gas emissions from their products and optimize waste management and recycling for them. This can be achieved, among other ways, by using more sustainable thermoplastics and quality-assured recyclates. A close cooperation between companies to establish material cycles and the recycling-friendly design of equipment are also important.

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.

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.

Erema enters a new dimension with large-scale recycling plants. Up to 40,000 tonnes per year of rPET can now be produced. The first plant of this size has been shipped to Brazil.

The reactor of the Vacurema T large-scale plant almost reaches the roof of the new Erema production hall, which was commissioned in 2021.

Additives manufacturer Milliken has developed viscosity modifiers specifically for recycled polypropylene (rPP). The products, called DeltaFlow, improve the flow behavior of rPP for extrusion and injection molding processes, according to the company.

The modifiers allow recycled PP to be processed at lower temperatures. Among other things, this reduces cycle times during injection molding.

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.

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.
