Despite fluctuations in the quality of input materials, end products are expected to meet high quality standards, especially in the food sector. The wide range of products available on the fast-paced global PET packaging market calls for a high degree of versatility on the part of plastics converters. For this reason, it is necessary to have lines which have a short process chain capable of producing good quality and which can respond rapidly to different requirements.

Recycling: Foaming instead  of Dreaming

The new plant will immediately produce an approximate 18,000 tons per year of recycled material from near-household collection.

At the new plant, the joint venture produces recycled PET granulate based on bottles from household waste for the production of new preforms and bottles.

Revalyu Builds Major Facility in the USA

Each year, more than one million tons of plastic waste are generated in Kenya – so far unused. T3 wants to change this and invests in a bottle-to-bottle recycling plant from Starlinger.

Around 1,334,000 tons of plastic become waste in Kenya each year.

In order to avoid bubble ruptures during the production of blown film, the velocity of the cooling air is often reduced. The use of air guiding systems (AGS) can prevent such bubble instability. A novel AGS was developed at IKV in Aachen, Germany, using iris diaphragms in order to increase the cooling efficiency of blown film extrusion and thus improve the productivity of an existing plant

New polymer composites for the production of multi-layer small tubes are being developed to give products specific functions. With suitable co-extrusion dies and a thermal barrier option, even complex layer composites with melt temperature differences of more than 50 °C can be processed reliably and in high quality.

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.

As the demand for recycled plastics grows, so does the size of the machines. This applies to the processing of polyolefins as well as to PET recycling. With its unique dimensions and production capacity, this new size of plant features a screw diameter of 280 mm, implemented for the first time in a Vacurema Basic 2628 T large-scale project for producing rPET pellets. Erema has just shipped the plant to a customer in Brazil.

Up to 40,000 tonnes per year of rPET meeting the highest quality standards can now be produced. „For this purpose, we installed a screw with a length of ten meters, a diameter of 280 millimetres and a weight of 3.5 tonnes, which is the largest ever used in one of our recycling machines,“ explains Managing Director Michael Heitzinger. The screw was manufactured by 3S, a subsidiary of Erema GmbH. No less impressive is the reactor of this recycling system, which, with a height of around 10 metres, is also unique and almost reaches the roof of the new production hall. 500 tonnes of input material were recycled during the test phase, which was subject to strict quality control. „The entire project was a great team effort,“ Heitzinger said, thanking everyone involved.

Extrusion Lines are Getting Bigger in Fast Speed

Just four years ago, the largest extrusion line supplied by Erema was designed for a throughput of 15,000 tonnes per year. This size of plant was ordered by customers once or twice a year. In the meantime, machines like this leave the production site in Ansfelden every month. As early as 2020, Erema proved to be a pioneer and reliable partner for implementing unique large-scale projects. That was when the food and beverage packaging manufacturer Envases Universales Mexico commissioned two Vacurema Basic 2625 T machines, each with a screw diameter of 250 mm and a capacity of 30,000 tonnes per year.
