Recycling experts in 
engineering plastics

In order to achieve the 1.5 degree target of the Paris Climate Agreement, greenhouse gases and the use of fossil fuels must be drastically reduced as quickly as possible.
Every day we are confronted with reports of extreme weather events such as droughts, heavy rain, floods, melting glaciers and tornadoes. In about 6 years, i.e. 2029, we will have exceeded the 1.5° C temperature increase. Only through the use of recycled materials is it remotely possible to conserve fossil fuel resources in the plastics sector.
We process recycled raw materials – primarily synthetic fibres from the textile industry – and, depending on the application, achieve
CO₂ savings of up to 90 percent for our customers – and even more for non-reinforced regranulates. For example, our PA66 recycled material without additives has a certified carbon footprint of only 285 kg CO₂eq/1000 kg, which corresponds to a reduction in emissions of 96 per cent compared to new materials. With our glass fibre-reinforced products, we achieve CO₂reductions of 82 to 93 percent, depending on the glass fibre content. Taking account of the material mix, we enable our customers to make massive CO₂ savings in this way — without compromising on quality.
We can tell our customers the exact CO₂emissions for each product manufactured. And we have also had the positive environmental effects confirmed externally. For ENTRON eco A – PA6.6 and ENTRON eco B – PA6 we have obtained an Environmental Product Declaration (EPD) on the basis of a life cycle analysis and a carbon footprint certificate, which you can also find on the website of the internationally recognised EPD organisation
. From our factory gates to the product ready for shipment, the CO₂ emissions have been calculated for each stage.
We want the plastics processing industry to face up to its responsibility with us and increase its use of recycled materials.

We produce exclusively in our own factories in the heart of East Frisia in Northern Germany. Through extensive energy management, we reduced our specific energy demand (kWh per kg) by 5 percent between 2015 and 2020. We have set ourselves the same goal again for 2025. Since 2021, we have been using 100 percent green electricity and also operate our own photovoltaic plant. We want to reduce our carbon footprint to zero by 2025. The energy management measures include extensive optimisation in production. For example, we have installed more energy-efficient electric motors at our plants, invested in new compressors and introduced automated line management to ensure a problem-free production process. These core measures are supplemented by improvements in the administrative area, for example motion detectors in corridors and heaters with digital thermostats. We have been ISO 50001-certified-since 2017, which means we meet the requirements for systematic energy management and have created an excellent basis for becoming even more efficient. In the near future, we are planning to use the waste heat from our cooling towers to heat our latest production hall. In the medium term, our business will be connected to the district heating network – preparations for this are already underway. To transport our goods, we rely on partners with “Green Logistics” certification and use rail transport whenever possible. In the long term, we want to reduce our ecological footprint continuously in all processes. We have now recorded our fresh water consumption as a performance indicator, for example, and we are working on a constant reduction.

Since 2009, ENTRON eco granules, our specially developed, sustainable plastic granules, have been on the market. We now also produce customised PA compounds without elastomers, foreign polymers and impact modifiers using our newly developed compounding process – and we do so purely mechanically. ENNEAFIL, our third product range, was developed in collaboration with the Institute for Construction Research at RWTH Aachen University and was awarded the seal. We also advocate the introduction of generally recognised quality standards and classifications for recycled plastics. This is necessary to increase the acceptance of recycled materials and ultimately the recycling rate on the market. In 2022, we introduced data quality level labels according to “Innovation Through Research”seal. We also advocate the introduction of generally recognised quality standards and classifications for recycled plastics. This is necessary to increase the acceptance of recycled materials and ultimately the recycling rate on the market. In 2022, we introduced data quality level labels according to DIN SPEC 91446 across the board at Enneatech. When the DIN SPEC for recycled materials was published in 2021, it was a huge step forward for the plastics industry. For the first time, recycled materials could be classified according to defined data quality levels (DQL). In this way, high-quality and environmentally friendly recycled materials from industrial waste can be differentiated from products made from “off spec” raw materials. Nevertheless, further standardisation is needed to establish recycling products even more firmly. That is why we are currently working with a consortium of other stakeholders in the plastics industry on DIN SPEC 91481 – a standard specifically for polyamide-based recycled materials. As a provider of an innovative product, the trust of our customers is particularly important to us. We have therefore had our high quality standards in production and delivery processes audited: ISO 9001:2015 certification confirms our successful implementation and realisation of a reliable quality management system.
