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

Both the quantity of recycled plastics waste and of processed recyclates is continually increasing. However, there are still difficulties with the quality of the recycled plastics, which are impeding replacement of virgin material. In recent years, machinery manufacturers and plastics producers have introduced various further developments that improve the properties of recyclates as well as eliminate unpleasant odors and contaminants.

Plastics recycling is a laborious process. For the recycled material to have the necessary quality, it must first be sorted into the different plastics

The Long Road to a Circular Economy

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.

The Plastics Industry Association (PLASTICS) published a report that analyzes scientific data on the environmental impacts of plastics and finds plastics to be more sustainable than alternative materials when life cycle assessments are taken into consideration.

Plastics Have Smaller Environmental Impact than Alternatives

The plastics industry has a variety of materials and technologies available for significantly reducing the ecological footprint of products. There are very few applications for which it is not possible to replace at least a portion of the fossil material with recyclates or bioplastics. Various methods, standards and software tools are available to determine what savings this can achieve.

Chinaplas 2022, to be held from April 25 to 28, will bring together more than 4000 exhibitors of the plastics and rubber industries from all over the world to launch innovative green solutions.

The 3rd Chinaplas x CPRJ Plastics Recycling and Circular Economy Conference and Showcase will be held one day prior to the show in Shanghai (photo from last year’s event).

The Theme Color of the Show Is Green

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.

Over past months, many in-house workflows and development processes have slowed down and also changed. Nevertheless, time has not stood still, also not in injection molding technology. The debate and development have been shaped by two themes: digitalization and the circular economy. Below are some examples of developments and projects that underpin this trend.

4-in-1 Sorter for PET Recyclers

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.
