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.

As expected, the K 2019 displayed a wide range of machine technology and complete system solutions for plastics recycling. At least since the trade fair in Düsseldorf, Germany, it has become obvious that industry today can offer solutions for closing the plastic cycle.

A Closed Recycling Cycle – Now!

Thanks to the combination of its Intarema TVEplus RegrindPro machine with the ReFresher, Erema has enabled the PCR-HDPE produced with it to be used in proportions of up to 100 percent for the production of packaging for direct contact with food and beverages.

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.

Present in a Multitude of Trends

Plastics processors have a wide range of colors at their disposal to color their products. Choosing the right color can ultimately be the key to success. But colors are just as subject to trends as materials and designs. Kunststoffe asked manufacturers of pigments, masterbatches, and colorants which colors would be particularly popular in the coming year.

What Will Be the Color of 2021?

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.

Plastics are among the materials most widely used for food contact applications. While there is pressure to use recycled plastics in packaging in order to combat plastic waste, certain conditions must be met before food packaging can be considered safe.

Today plastics recycling is usually only classified as being either mechanical or chemical. However, precise differentiation is crucial for any assessment of the possibilities and limitations of plastic recovery processes and whether materials are actually being recycled or merely their raw materials recovered.

The Role of Chemistry in  Plastics Recycling

Polymer materials, including synthetic polymers, have a bad reputation. These image problems do not just arise from the current environmental debate but also have earlier origins. In the past, too, polymer materials were subject to unjustified criticism. This often stemmed from non-scientists and frequently betrayed a lack of scientific knowledge.

On the Image of Plastics and their Responsible Use

For almost two decades, an expert committee, meeting once a year, has supported Kunststoffe magazine in determining the state of play in the plastics industry and identifying current technical developments. This time, the traditional spring meeting gave it an opportunity to debate the consequences of the Corona virus.

Starting up under the Shadow  of Corona

The increasing volume of plastic waste and the growing pollution of the oceans by such waste have brought the sustainable handling of plastic products into the focus of society and politics. Both recycling and bioplastics can be a part of a strategy for greater sustainability, but they are not free of side effects. In order to avoid irrational decisions, it is important to assess their effects comprehensively.

Why Recycled Films Are Not Necessarily Sustainable

The beneficial processing and service properties of plastics are increasingly determining the ecological fate of the world. The plastics industry has now realized that it is not enough to put the blame on consumer behavior. As K 2019 showed, numerous initiatives and technical developments are paving the way for the urgently needed establishment of a circular economy.

A Shredder-Extruder Combination as a Recycling Solution in Injection Molding Production

Pure Loop, an Erema Group company, will present its Isec evo series at Fakuma. This shredder-extruder combination is rapidly becoming established as an efficient recycling solution in injection molding production thanks to its high flexibility in processing different materials, simple operation and low maintenance requirements.

Isec evo is a high-performance material all-rounder that has been specially designed for recycling different types and shapes of material, regardless of whether solid parts or hollow bodies, roll stock or punched waste or waste from injection molding production such as sprues, sprue patties and regrind. This is made possible by the unique input technology that features a combination of a double feed ram system and single shaft shredder. The wide range of applications for this technology is confirmed by a look at the list of Pure Loop customers. Among others, it includes suppliers to the automotive industry as well as a well-known German manufacturer of writing instruments. This company recycles PP injection molding waste to make recycled pellets that are used to produce the black caps for one of its pen series. “These application examples show that the repelletizing of production waste offers significant advantages in terms of the efficiency of the recycling process, the quality of the recycled pellets and, as a result, the refeeding quotas and costs compared to refeeding regrind material,” explains Manfred Dobersberger, Managing Director of Pure Loop GesmgH.

In a series of tests carried out together with Engel, an injection molding machine manufacturer, and Profol, a cast film manufacturer, Pure Loop recently proved that recycled pellets produced from glass fiber-reinforced organo sheets can be processed in the injection molding process just as well as virgin material. “The excellent quality of the components produced during trials indicates that the processing of organo sheet offcuts has great potential for series applications in the automotive lightweight sector,” says Dobersberger, who is convinced of this future-proof recycling solution’s capabilities.
