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.

Unique PET Tray-to-Tray Recycling in a Single Extrusion Step

The Danish company Plastix recycles old fishing nets and ropes. The granules produced are used by JSP International, among others, to manufacture expanded polypropylene (EPP).

11 % of the plastic waste in the sea comes from the maritime industry. For the recycling of old fishing nets and ropes, accurate sorting is very important

From Fishing Net to Particle Foam

Process technologies for manufacturing multilayer and multicomponent products offer great potential for using reprocessed plastic wastes even for plastic parts that are subject to strict requirements for surface quality, product protection or consumer safety. The key: to place the recycled material in the interior while the surface is made of virgin material. Engel has developed a variant of sandwich injection molding that allows high proportions of recycled material to be used even with complex part geometries.

The sandwich technology (skinmelt) hides the recycled material beneath a virgin material surface – for example in the transport boxes

Smart assistance systems are paving the way for self-optimizing production. Automatic correction of quality-relevant parameters is already reality for individual phases of the injection molding process. At K 2019, Engel presented the iQ weight control with the example of a recyclate application for the first time.

Opening up a Broader Range of Applications for Recyclates

Current requirements for product quality and rising demands for sustainable products are dictating ever stricter requirements regarding the quality of recyclates. Further technological developments aimed at material purity and quality are unavoidable.

Circular Economy Is the Buzzword  of the Hour

Enhancing mixed bottle flakes by turning them into extrudable recycled crystalline polyethylene terephthalate (rCPET) was the goal of a joint development project looking to close the gap in the PET recycling system. By successfully producing a sheet made from recycled material suitable for high-quality applications such as thermoformed food trays, Gneuss, Sukano and Illig have demonstrated that this approach is indeed possible.

PET: From A to C

Paint bucket or A-pillar finisher? In our thoughts and attribution of value, packaging items and high-tech components often represent opposites. Yet the two can complement one another – when you look at used packaging as a valuable raw material. At the fair, KraussMaffei will be showing the concept for a closed material cycle and is making plastics processing sustainable through this.

First a bucket or another plastic product, then raw material for further processing: the shredded post-industrial material

In this interview with Kunststoffe, Alfred Stern, CEO of Borealis, explains why he considers fixed recycling quotas to be necessary and why voluntary commitments do not work.

Together with Tomra and Zimmermann Recycling, Borealis has built a demonstration plant in Lahnstein. According to its own information, the most modern plant for mechanical recycling is intended to show what is possible with modern technology and equipment in a state-of-the-art plant for mechanical recycling

The development of a functioning and efficient recycling economy is strongly dependent on the quality of the recycled plastics. New plant and process technology is promoting this development.

For a functioning circular economy, plastics must not only be extracted from post-consumer waste streams, but the recyclates obtained must also be of consistent quality

Recyclates usually show altered properties compared to virgin plastics due to initial processing and influences during the product’s life. This often leads to problems during processing. Especially in melt-expanding processes such as injection stretch blow molding, blow molding, film blow molding or thermoforming a fast incoming goods inspection method for recyclates is important. The Institut für Kunststofftechnik (IKT) at the University of Stuttgart, Germany, has developed a new test method for this purpose.

Recyclates on the Test Bench

On March 24, 2022, the fourth “Forum Plastic Recyclates” event will be held as virtual conference.

What sustainable plastics solutions are available for automotive electronics? How exactly does optimized, high-quality polyolefin recycling work? These are just some of the questions that will be addressed at the fourth “Forum Plastic Recyclates” event to be held on March 24, 2022.

Addressing topics such as the recycling market and recycling standards, using additives to improve quality and applications for recycled plastics, this year’s forum will focus once again on the field of mechanical recycling. The program and online registration form for the virtual conference are now available <a href="https://www.kunststoffrezyklate.de/" target="_blank">here</a>.

International Knowledge Sharing in the Plastics Industry

Delivered in English, the virtual conference of the Fraunhofer Institute for Structural Durability and System Reliability LBF will allow participants to enter into dialog at an international level and will bring together representatives from plastics manufacturers, plastics processors and recycling providers, as well as user industries such as the automotive, white goods, construction and packaging industries.

The conference’s digital format will provide various opportunities for direct interaction between participants and speakers, while also allowing high-level, technical discussions and the chance for participating companies to update their knowledge.

At the Interface between Science and Industry

As an applied research institution and impartial source for information, Fraunhofer LBF acts as an interface between science and industry, and plays a leading role in the research landscape, particularly in the field of recyclates. Through hosting numerous technology conferences and industry working groups, the Darmstadt-based research institute has held a strong position in the plastics industry for many years and, as such, is taking over  the event from the Hanser Verlag. Hanser Verlag will continue to support the conference in an advisory capacity.

The “Forum Plastic Recyclates” will host discussions on a variety of topics, including ways in which recycled plastics can be used in everyday life. The path to achieving this will be based on single-variety recyclates.
