From the Sector

Breaking new ground in plastics recycling means assessing the value chain from end to end. The big opportunities for the future are in fine-tuning the individual process steps; from the collection of recyclable materials to the recycling process and the end product. This is where the cooperation of Lindner and the EREMA Group comes in, officially launched following the 50/50 founding of the holding BLUEONE Solutions in August 2023 to which shares of Lindner Washtech were contributed. The expertise of EREMA, a manufacturer of extruders and filtration solutions for plastics recycling and the largest company within the EREMA Group, has now been combined with the expert know-how from Lindner Washtech, a leading provider of all-in-one solutions for shredding, sorting and washing plastic feed materials.

Data transfer ensures more efficient recycling processes
Process control is an especially important aspect of plastics recycling, which is why standardising the process control system was what the two companies focused on first. "Together, we have developed a platform that allows data to be exchanged between the extruder and the washing system," says Manfred Hackl, CEO of the EREMA Group at IFAT in Munich. "This enables us to analyse the data more precisely so that effective improvement measures can be deduced." All key parameters are taken into account and monitored via a digital interface. For example, it is possible to use information relating to the current throughput of the EREMA Pre Conditioning Unit to optimise the washing process as soon as possible so that it can compensate for fluctuations in capacity and achieve a significant increase in output. This data transfer represents a new step on the roadmap to digitalization.

High efficiency due to smart energy management
"To ensure sustainable recycling, it is necessary to find the right process for each application and to make sure that the individual process steps are perfectly coordinated," emphasizes Michael Lackner, Managing Director of Lindner. Coordinating the process steps has already achieved initial success in energy management, and a clear example of this is heat recovery. "We use the latent heat generated during the extrusion process as an energy source for the washing and drying process," explains Lackner. "This enables our customers to sustainably reduce their energy costs and carbon emissions".

Making the most of synergies along the value chain
Synergies need to be used to establish the quality standards specified for each end application. "The key question is how we can improve the end product and increase the overall efficiency of the recycling process at the same time," agree Manfred Hackl and Michael Lackner. This will only work if companies work together along the value chain. The industry leaders can already point to several examples where together they have improved recycling processes and made it possible to move away from downcycling. "An example of this is the recycling loop of HDPE starting material, which is processed into high-quality, food-safe rHDPE pellets using our two technologies," says Lackner. Lindner Washtech and EREMA continue to work intensively together to develop strategies for upcycling plastics and increase recycling rates.

As of 30 May 2022, EREMA Group GmbH acquired 19.8 percent of plasticpreneur® gmbh. plasticpreneur® is an Austrian start-up company founded two years ago that manufactures at its production site in Klagenfurt recycling solutions for plastic waste that are mobile and can be operated without prior knowledge. The machine portfolio covers the recycling process and the production of new end-products. Due to it´s wide range of applications, it is in demand both in the Global South and in industrialised countries.

In the two years since the company was founded, plasticpreneur® has already sold 330 machines to customers in over 70 countries on all continents. In addition, they have made over 750 application-specific moulds, many of them custom-built to comply with individual customer specifications.

While plastics recycling has gained enormous momentum in the industrialised countries, more remote and poorer regions of the world have hardly benefited from high-tech solutions for industrial recycling processes so far. They are held back by a lack of infrastructure and know-how. That is why waste is often incinerated or disposed of in landfills, rivers and the surrounding environment. "Our mission - Another life for plastic, because we care - is also aimed at supporting these regions with solutions for plastic recycling, and with plasticpreneur® we have found the ideal partner for this," says Manfred Hackl, CEO EREMA Group.

The start-up company's machines can process HDPE, PP, PS, LDPE, PLA, AB and TPU separately. Their product range includes a shredder, injection moulding unit, extruder unit for the production of end products, air filters as well as custom-built moulds. "For our machines to be used in regions with little infrastructure, they must be easy to operate without prior knowledge. The fact that we also develop end-product solutions needed locally makes our range of services particularly attractive here," explains Sören Lex, CEO and co-founder of plasticpreneur®. As soon as recycling also becomes a source of income for the operators, they become entrepreneurs. That explains the name of the start-up, a word created from "plastic" and "entrepreneur". plasticpreneur® customers in these countries include e.g. social enterprises and operators of refugee camps, where everyday consumer goods - from clothes pegs and school supplies to toys and fence posts - are produced and sold using plastic waste. This means that the added value stays local.

The demand for plasticpreneur® machines is also increasing in industrialised countries. On the one hand by educational institutions and organisations that use them to raise awareness of the need for a circular economy in workshops and to give pupils as well as adults a better understanding of plastic recycling. On the other hand by customers who are developing new end-products for plastic waste together with plasticpreneur®. Because the machines are so easy to operate they enable a low-theshold use of recycled plastics in product development processes, starting from generating prototypes to launchin small series production. Small companies, product designers and developers therefore are another steadily growing customer segment.

• Successful acquisition of Austrian plastics recycling company Ecoplast Kunststoffrecycling GmbH

Borealis, a leading provider of innovative solutions in the fields of polyolefins, base chemicals and fertilizers, announces today that it has fully acquired the Austrian plastics recycler Ecoplast Kunststoffrecycling GmbH (“Ecoplast”). Based in Wildon, Austria, Ecoplast processes around 35,000 tonnes of post-consumer plastic waste from households and industrial consumers every year, turning them into high-quality LDPE and HDPE recyclates, primarily but not exclusively for the plastic film market.

The expectation of Borealis is that the recycled PO market will grow substantially by 2021, which is the strategic rationale behind the acquisition. The company has made PO recycling a key element of its overall PO strategy because of its potential to support both growth and sustainability. Borealis has been an industry frontrunner in making polyolefins more circular. In 2014, it began offering high-end compound solutions to the automotive industry, consisting of 25% and 50% post-consumer recycled content. Borealis was also the first virgin PO producer to explore the possibilities of mechanical recycling, by acquiring one of Europe's largest producers of post-consumer polyolefin recyclates - mtm plastics GmbH and mtm compact GmbH – in July 2016. Since then it has continued to invest into the development of technology and new products in the area of circular polyolefins.

“Borealis recognises the increasing need for plastic recycling and sees the Circular Economy as a business opportunity. Borealis already has a long-term collaboration with Ecoplast and this acquisition is the next logical step in building our mechanical recycling capabilities. As an important complement to mtm in Germany, Ecoplast will help us address critical sustainability challenges and become a polyolefin recycling leader. Eventually, we want to use our experience to develop an effective blueprint for the end-of-use phases for plastics that can be applied in other parts of the world,” says Borealis Chief Executive Alfred Stern.

“We are very happy that the transaction with a strong and reliable partner such as Borealis has been successfully concluded and are looking forward to our common future activities on the recycling market. We have located potential synergies in many operative and strategic areas, especially in product quality R&D and future applications of polyethylene-film-recyclates. The combination of Ecoplast and Borealis holds the potential to be groundbreaking for the market,” says Ecoplast’s Managing Director Lukas Intemann.
