Scientifically proven climate protection
In its annual study “resources SAVED by recycling”, the Fraunhofer Institute UMSICHT calculates the extent to which the environment has been helped by Interzero’s recycling services. In 2022 alone, this study showed that 2.1 million tons of resources were handled by closed-loop systems run by Interzero’s companies such as Interzero in Germany, Austria, Poland; Italy and Slovenia, saving around 8.7 million tons of primary raw materials . This is comparable to the weight of 174,267 single-family homes . The companies also saved around 1 million tonnes of greenhouse gas emissions – this corresponds to the average annual CO 2 emissions of over 100,000 four-person households .

Reducing transportation, reusing IT devices
In another study from the “resources SAVED” series, Fraunhofer UMSICHT looked at the positive impact on resources and the climate from the refurbishing and reuse of IT and communications devices , as organized by Interzero. As one example, using refurbishment to extend the service life of just one laptop saves around 181 kg of primary raw materials and 154 kg of greenhouse gas emissions.
Interzero’s Mobile Counting Center (MCC) also helps save resources. The local availability of the mobile counting service for non-refillable bottles means companies avoid long trips to stationary counting centers. “resources SAVED” shows that the MCC’s annual CO 2 savings equal the amount removed by around three wooded football pitches.

“From recyclable product design to sustainable recovery, successful circular transformation requires all stakeholders in the value chain to pull together.”

Trade in raw materials
Trade in raw materials
Interzero buys recycled materials throughout the Republic of Croatia, processes them and supplies the industry with high-quality recycled raw materials for new products , thereby making its contribution to the circular economy.
Buying, selling, recycling: the engine of sustainable development
By buying, selling and recycling recyclable materials, Interzero invests in resource conservation and enables a circular economy. We process used materials in our own facilities or at our partners, and then deliver sorted and recycled resources to industry. As an authorized waste management company, Interzero meets the highest standards in the field of material recycling.
The most common raw materials that we buy, sell and recycle are: paper and cardboard, different types of plastic polymers, metals (non-ferrous and black).

We close the loops


We close the cycles of waste raw materials and thereby protect natural resources and reduce greenhouse gas emissions. Based on professional knowledge, many years of experience and a wide network of waste streams, we can help you in the procurement of any raw material. Together we create a network that suits you, from which you can get recycled plastic or other raw materials you need.
In recycling facilities in Germany, a wide range of fractions and polyolefins can be processed into sorted recyclates. As raw material, we use materials from household recycling collections, mainly polyethylene (PE) and polypropylene (PP) packaging. We use it for the production of various products: Granulat Recythen is suitable, for example, for the production of cable drums, garden furniture and drainage and protection pipes for cables. Procyclen is an award-winning, flexible compound. Thanks to special formulations, it can be precisely adapted to customer requirements in terms of flowability, durability, UV and heat or color resistance. The following applies: Similar to a new crude oil-based material, Procyclen meets the high demands for new product or packaging properties – and can also be processed by injection or extrusion processes, which differentiates us from the competition.

Check for recycling
CHECK FOR RECYCLING - Do you want to make your packaging more sustainable?
Recycling represents an effective way of preserving natural resources and the possibility of including waste raw materials in the circular economy cycle. If the amount of single-use plastic is not limited, it is predicted that by 2050 there will be more plastic in the oceans than fish.
In order to close the circle of materials, it is necessary to know the proper procedure of separate waste collection.Bottles made from recycled PET material, for example, have become a textbook example of reuse in the packaging industry. With the “Check for recycling” check for recycling, Interzero brings sustainable strategic measures in the field of packaging to the Croatian market.
Check the recyclability of your product’s packaging and get the “Check for recycling” sign, which will place you among the companies that manage their packaging sustainably. We analyze the recyclability of your packaging using a software tool that determines the possibility of collecting, sorting and processing the packaging. Based on good input data, you can get a quick assessment of the recyclability of your packaging.
If your packaging has achieved a high recyclability rating, you will receive a “Check for recycling” mark. Otherwise, we provide expert guidance on how to improve the packaging. The service is intended for suppliers and companies that sell packaging or products in their own packaging.
