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.

Luminous Markers instead of Holy Grail

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

Repi offers various additives for recycling PET, which can be used, for example, to prevent the material from darkening.

Compensating for Darkening in Recycled PET

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.

Start into a Second Life for Plastics

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.

Engel has developed a new way to process plastic scrap as flakes on an injection molding machine straight after grinding. This innovation eliminates the pelletization step and significantly boosts the economics of plastics recycling. The key to consistently high product quality is to vent the plastic melt.

Test setup at the pilot plant in St. Valentin, Austria: for the two-stage process, Engel has combined a plasticizing screw with an injection screw.

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.

Recyclers can use DeltaFlow, a solid concentrate, to increase the melt flow rate of recycled polypropylene (rPP) for the extrusion and injection molding processes. Milliken offers the new viscosity modifiers in free-flowing pellets, which reportedly makes the product easy to feed, safe to handle and dust free.

DeltaFlow-optimized resins allow for lower processing temperatures, which can enable converters to reduce cycle times, boost productivity and improve processability. It is available in concentrations of 2, 5 and 10 % to meet varying applications and equipment requirements.

According to the company, DeltaFlow enables recycled polypropylene to feasibly replace virgin resin in many end-use applications. This allows brands to use more rPP in their products, thereby helping them to meet their sustainability goals.

This new concentrate complements Milliken’s existing family of DeltaMax Performance Modifiers for polypropylene that enhances the physical properties and melt flow of rPP resins by allowing recyclers and converters to optimize their formulations and blends machine-side.

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