Success for groku with RecyClass

What counts for us are transparent and credible contributions in terms of sustainability!

We at groku are therefore always taking the next steps and have had our first bucket, the EZE12500, see photo, from our product portfolio tested for recyclability by RecyClass. It was awarded the highest rating, recyclability A.

This shows how effective and environmentally friendly modern plastic packaging solutions can be.

RecyClass is a cross-industry initiative focused on promoting and improving the recycling of plastics through assessment, certification and design guidelines.

We at groku see this result as a promising start to our collaboration with RecyClass – for a more sustainable future through innovation, transparency and harmonized recycling standards in Europe.


As shown here, the EZE 12500 has been awarded the highest rating, recyclability A, by RecyClass.

Photovoltaic expansion at groku is progressing

A further plant has now been put into operation and this will now generate approx.
700,000 kWh of clean energy a year at the site.

A large proportion of this energy will also flow directly into our production.

This makes groku one of the largest PV producers in the region and makes an important contribution to sustainability through renewable energies andCO2 reduction.

Nothing is lighter than our 5-liter bucket!

Our new highlight, the EZE 5600 in the lightweight series, not only saves resources and CO2 and produces less waste, but is also highly transparent and thin-walled. Its modern and high-quality design meets the needs of customers for clear product presentation.

After 5 years of continuous development, we have reduced the weight of the bucket (without handle) in two stages: from an initial 140 g by almost 25 % to a super-light 108 g. The first samples are already running on our new production lines.

For our ecological footprint, this means a saving of over 30 tons of plastic for a production of 1 million buckets.

These great results were only possible thanks to close coordination with our food customers. They are also pleased to be able to make their contribution to the sustainability sector. Curious? We would also be happy to check your articles for material and cost savings.

We give it a reliable seal of approval!

With REDcert2 certification, we can offer our customers an honest sustainability promise regarding the use of recycled materials.

Our packaging buckets are up to 100% recyclable, the raw materials used are traceable and therefore always known.

We are delighted that our partner Knauf Gesellschaft m.b.H Austria has opted for groku buckets, in the production of which 70% of the raw materials required are replaced by sustainably certified recycled materials.

The important message of this project: transparency in terms of sustainability. With the REDCert² seal applied, Knauf passes on its sustainability promise to the end consumer.

Our partnership is a good example of how companies can work together towards a greener future. We look forward to taking further steps in this direction!

Alpina pure colors in recycling containers

Our 2.5-liter bucket, HOM4000, is now also available in recycled material with a plastic strap – making it completely recyclable!

We are delighted that our partner DAW SE, a company in the paint and coatings industry, uses our resource-saving recycled containers to fill Alpina pure colors.

In addition to the sustainable outer packaging, Alpina attaches great importance to the ingredients. The colorful interior paint is free from animal ingredients, plasticizers, solvents and preservatives. All paints bear the “Blue Angel” eco-label. Pure sustainability that fits together perfectly – that just makes us happy!

Insights into the sustainable packaging industry

We at groku Kunststoffe GmbH recently accepted the invitation from interseroh+ to take part in a workshop on sustainable packaging in Berlin. As a long-standing partner of the recycling and system service provider interseroh+, we have been consistently developing our sustainability goals together for a long time.

The use of the “Made for Recycling” sustainability seal from interseroh+ underlines our cooperation and we were looking forward to the exchange on site.

Christian Henrichsmeier, sustainability expert and Head of Technology at groku, took part on behalf of groku. The workshop provided a valuable insight into new market trends and the legal framework of the Packaging Act and the minimum standard of the central packaging register. This information is of great importance to ensure that we design our activities in accordance with legal regulations and make our contribution to the circular economy.

The visit to the modern ALBA LVP sorting plant was particularly impressive. It was an impressive experience to see what happens to our packaging once it has fulfilled its main purpose and how the right design for recycling can help a bucket become a bucket again.

“When you stand at the sorting belt and see the variety of packaging passing you by, you realize how strongly our consumer behavior is linked to this flood of materials. The constant influx of trucks in the yard of the sorting plant made it clear to us that there is no standstill and that we must continuously work on developing effective recycling solutions,” says Henrichsmeier.

Another focus of the workshop was on evaluating the recyclability of our packaging and identifying optimization potential. The focus was always on the elementary functions of the packaging. “We are proud of the fact that we are already very well positioned and are consistently pursuing our sustainability goals,” concluded Henrichsmeier.

Overall, the interseroh+ workshop was an extremely enriching experience for us. We will continue to intensify our efforts to promote sustainable packaging solutions and actively contribute to the creation of a circular economy.
