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.

Pan-European Recycling Platform Is Growing

Anviplas Becomes Part of the Repeats Group

Repeats (Recycled PE at Scale) Group, a pan-European platform for LDPE recycling, made an investment in the Spanish recycling company Anviplas.

For Repeats this investment in Anviplas represents an important step in building a pan-European plastics recycling platform. Under Repeats’ leadership, the company plans to nearly double its production capacity to meet the growing demand for recycled LDPE in Europe. Aleix Vintró will continue to lead the Spanish operations and expansion plans going forward.

The Spanish recycling company Anviplas has been involved in plastics recycling for more than 30 years, during which time it has built up extensive know-how that now benefits customers throughout Europe, in Africa and in Asia. Their cooperation with Erema is almost as long. Since 1991, Anviplas has relied on the technology and service provided by the Austrian recycling machine manufacturer.

“Erema machines have delivered excellent results at our company over all these years. Featuring industry-leading technology, these machines are also easy to use, very reliable, and they have always met our expectations. Even on particularly challenging projects,” says Anviplas CEO Aleix Vintró, who took over the business from his father Joan. He highlights the recycling of barrier film as an example, which consists of three different layers of material.

Anviplas customers manufacture a huge bandwidth of products made using their recycled pellets. They range from various film products, such as stretch, shrink, mulch and silage films, to irrigation, corrugated and high-pressure pipes, as well as containers such as tubs, bottles, barrels and crates. All these applications require recycled pellets that meet the highest quality specifications. “That is precisely our strength,” says Aleix Vintró. “We produce the highest possible quality recyclate, because we want to continue to offer our customers products that optimally meet their needs and open up business opportunities that are cost effective and environmentally sound.” That is why Anviplas is currently working intensively on improving the recycling process for complex multilayer materials.
