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

Important Step towards Pouch-to-Pouch Recycling

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.

The growing demand for plastic recycling directly reflects the machine sales for Polystar. By the end of April 2022, a total of over 110 recycling machines will have been shipped within 12 months – twice as many compared to last year.

The new factory in Sinji industrial park is the third Polystar manufacturing facility in Taiwan.

Sales Doubled for Polystar in 2021

Conventional PET recycling lines are based on single-screw extruders with maximum output rates of two and a half tons per hour. Since 2004, KraussMaffei has been researching a process to significantly increase these quantities with the help of glycol and the use of a twin-screw extruder. Given the current high demand for rPET materials, this technology is becoming increasingly 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.

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.
