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.

XXL Recycling Plant for Brazil

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.

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.

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.

The modifiers allow recycled PP to be processed at lower temperatures. Among other things, this reduces cycle times during injection molding.

Together, the two companies want to tackle the challenge of plastic packaging waste and its recycling.

The partnership between Borealis and Reclay aims to accelerate the shift to a circular plastics economy.

Researchers from the University of Birmingham, U.K., and Duke University, U.S., have created a new family of polymers from sustainable sources that retain all of the same qualities as common plastics, but are also degradable and mechanically recyclable.

Aimplas has completed a project to recover end-of-life fishing nets and other marine litter to manufacture furniture made of 100 % recycled plastic.

At an event at the Innsomnia facilities in the Port of Valencia, a bench was unveiled measuring 6 m long and weighing more than 800 kg. It is made of recycled plastic profiles with 15 % fishing nets and other marine litter.

The Theme Color of the Show Is Green

In addition to mechanical recycling, chemical recycling is increasingly coming into focus for more challenging plastic streams. This article provides an overview of different recycling processes – and the challenges that arise, particularly in the area of food packaging as a result of regulations or the cost-effectiveness of the process.

Chemical recyclers and raw material producers rely heavily on processes that are covered by the collective term thermal conversion, which includes pyrolysis.

BariQ is expanding and upgrading its existing plant with another Starlinger PET recycling system and an additional solid-state-polycondensation (SSP) reactor.

Andreas Pechhacker, General Manager Starlinger recycling technology, Mostafa Khairat, CEO BariQ, and Tasos Bereketidis, Sales Director Emerging Markets at Tomra Sorting Recycling, signed the contracts for the plant expansion.

Sorting plays a crucial role in the processing of plastic waste. Systems based on artificial intelligence are one way of improving this. Sorting systems manufacturer Tomra has recently presented corresponding technologies. Kunststoffe spoke about this with Felix Flemming and Valerio Sama from Tomra. In the interview, they explain what progress can be made with it, how important digitalization is for this and what improvements it means for food packaging.

“AI Has Great Potential for  Sorting Food Packaging”

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

Over the last year, the German branch of the Association of Plastics Manufacturers, PlasticsEurope Deutschland, consistently advocated the technology of chemical recycling. Meanwhile, chemical recycling has not only been criticized by environmental organizations but also from parts of the industry. Kunststoffe interviewed Ingemar Bühler, CEO of the Association, about this criticism and the competition between mechanical and chemical recycling. In the interview, Bühler also addresses further requirements for a circular economy with plastics and explains why he considers a label for plastics products a sensible idea.

“There’s No Point in Arguing over Chemical versus Mechanical Recycling”

High Demand of Plastic Recycling Machines

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.

New regulations in many countries now require producers to use a higher percentage of recycled content in flexible and rigid packaging products. Instability of raw material prices and supplies also forces plastic producers to better recycle their own production waste. Therefore, plastic recycling machines are getting bigger. Recyclers are now buying larger-capacity machines and more machines. The 800 to 1000 kg/hour pelletizing extruder has become a standard for post-consumer and even some post-industrial recyclers. A Japanese post-consumer recycling company just placed an order of four of these machines from Polystar in December 2021. In the same month, several recyclers in Australia, Colombia, Mexico, Russia and the US have also repeated their orders with multiple higher-capacity machines to be able to comply with the increasing recycling demand of washed PE film and bottle waste.

Post-Industrial Recycling –  Higher Quality Requirement

Reusability of the recycled pellets has become more important than ever for plastic producers who recycle and reprocess their in-house waste. Packaging film and woven bag producers now require higher quality recycling in order to reduce production cost as much as possible. In India, the requirement of more advanced recycling machines is rising, especially for PP raffia, woven bags and FIBC producers who need to process their internal waste. 75 Repro-One recycling machines have been installed in this sector alone in India. The Repro-One recycling technology is a combination of shredder, extruder and pelletizer into one machine. This one-step, powerful (shredder) yet gentle (low processing temperature) process produces the best possible pellets quality at the lowest operation cost, enabling the producers to reuse all of the pellets back in PP tape extrusion lines.

The packaging film sector (stretch film, CPP film, etc.) and plastic bag producers are required to use a much higher percentage of recycled pellets in the end products. For better quality control and to maximize the reusability back into the film extrusion lines, more producers have decided to recycle all the production waste internally instead of outsourcing it. Recent installations of the Repro-Flex recycling machines (a cutter-compactor integrated model designed for recycling film waste) in Denmark, Italy and Switzerland are equipped with smart features to minimize energy consumption and labor intervention.
