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.

Closed Recycling Loop for PET-Based Multilayer

In the manufacture of semi-finished products such as fibers or films, waste that can be recycled and reused as a raw material is repeatedly produced along the entire production chain. The recycling of PET is a particular challenge to the plant construction because of the hydrolytic polymer degradation.

Engel has developed a new way to process plastic scrap as flakes on an injection molding machine straight after grinding. This innovation eliminates the pelletization step and significantly boosts the economics of plastics recycling. The key to consistently high product quality is to vent the plastic melt.

Test setup at the pilot plant in St. Valentin, Austria: for the two-stage process, Engel has combined a plasticizing screw with an injection screw.

PlasticsEurope plans to significantly increase investment in chemical recycling: from EUR 2.6 billion in 2025 to EUR 7.2 billion in 2030. To further accelerate investments in this key technology and the transition towards a circular economy, the Association calls for a strong policy and regulatory framework.

1.2 million t of recycled plastics is the industry’s target for chemical recycling in 2025. By 2030, this figure is expected to rise to 3.4 million t per year

European Plastics Manufacturers Invest in Chemical Recycling

Coperion is supplying an extrusion system to Ghent University in Belgium for comprehensive research and development tasks in chemical recycling of mixed plastic waste. The system will also be available to Coperion´s customers for testing.

Due to its intensive dispersion and devolatilization output, Coperion’s ZSK twin screw extruder is extremely well suited for energy-efficient chemical recycling of mixed plastic waste

High Performance Melt Filters for Higher Throughputs

Two new models of the Eco product family from Ettlinger take into account the need for systems with a higher product throughput.

Two new models of the Eco product family from Ettlinger take into account the need for systems with a higher product throughput and are initially available in sizes suitable for medium-sized recycling lines.

The new performance enhanced ECO 350 replaces the former ECO 250, while the new ECO 500, capable of achieving capacities of up to 4000 kg/h, replaces the former ECO 250 Twin. The ECO 200 completes this range.

Ettlinger’s melt filter technology is based on the principle of self-cleaning with a continuous flow of melt from the outside to the inside of a rotating, perforated drum. A scraper removes the contaminants that are held back on the surface and feeds them to the discharge system. Just like the ERF filters, which are designed for higher contamination, the new ECO filters also have a modular structure, thereby providing a wide range of options for adjusting the filter properties to the respective task.

A new innovative system facilitates an even higher concentration of contaminated discharge, which, in turn, further decreases the already typically low loss of PET melt associated with the melt filters. Better access to the scraper system reduces the amount of time needed by the operator for maintenance and replacement tasks. The discharge now exits via the front side of the ECO filters, which is generally easier for the user to access.

Uwe Kellner, Managing Director Ettlinger: “PET recyclers are reporting ever-increasing volume flows, resulting in a sharp increase in the capacity utilization of many machines. At the same time, buyers have more stringent requirements regarding the purity of the recycled material. Consequently, many of the filter systems in operation today are reaching maximum capacity. Our further developments have been tailored to these changes in the market. With these in mind, we have achieved enhanced performance without compromising on filtration efficiency. The new designs combine screen sizes up to 60 µm with a minimum loss of PET through the discharge.”

The ECO melt filters are designed to process very low viscosity polymer feedstock (mainly PET and PA) and to facilitate the efficient filtration of contaminants such as paper, wood, aluminum, silicone, etc. Moreover, the closed discharge system prevents the occurrence of black specks.

For this reason, the classic application for ECO melt filters is extrusion systems where PET bottle flake is converted into food packaging films, packaging tape and fibers, as well as PET repelletizing and compounding processes. ECO melt filters are suitable for single-screw or twin-screw extrusion lines, irrespective of the pelletizing system or other downstream units, and can achieve throughputs from 150 kg/h up to 4000 kg/h.
