A closed loop for paper sacks
Through its take-back and recycling system for used kraft paper sacks, Interzero supports manufacturers, fillers, distributors and commercial users in closing material loops and keeping valuable resources in circulation. At the same time, REPASACK makes an important contribution to meeting the take-back, recycling and circular economy requirements under the Packaging Act (VerpackDG) and the Packaging and Packaging Waste Regulation (PPWR).
REPASACK for manufacturers, traders and fillers

Anyone who regularly places paper sacks on the market can rely on the Interzero Repasack take-back scheme. REPASACK supports companies in the legally compliant collection and high-quality recycling of used paper sacks. The REPASACK symbol confirms participation in the system and stands for organised collection and resource-efficient recycling in accordance with the requirements of the Packaging Act Implementation Act (VerpackDG) and the objectives of the European Packaging and Packaging Waste Regulation (PPWR).
After collection, the used kraft paper sacks are sorted by product type and processed at Interzero’s own recycling plant. This produces high-quality secondary raw materials that can be reused in the paper industry, thereby helping to close material cycles.

REPASACK for end consumers

Whether it’s cement, flour or plastic granules – used paper sacks are generated in many industries. Interzero organises their collection and high-quality recycling as part of the REPASACK system. Commercial end-users can hand in their empty REPASACK paper sacks free of charge at over 300 collection points across Germany.
The collected sacks are sent for recycling and reintroduced into the recycling cycle as a high-quality secondary raw material. In this way, REPASACK makes an active contribution to conserving resources and promoting a functioning circular economy.

Hazardous substance or pollutant? No problem!
For paper sacks used to transport products classified as pollutants, we offer the REPASACK-G-system (“G” for Gefahrstoff = hazardous substance). Here too, we offer free-of-charge take-back for paper sacks at sites throughout Germany. Our Interzero Repsack service starts at the point where paper sacks are emptied, i.e. at the customers of manufacturers and fillers.

Frequent questions of our customers
- How can I participate in the REPASACK system as a manufacturer or distributor?
There are two options here:
1. The most straightforward option is to sign a contract with Interzero Repsack GmbH itself and acquire a trademark usage licence for the REPASACK symbol directly. You can use this to authorise a paper sack manufacturer to print this symbol on your paper sacks. You then simply pay the licence fee for the paper sacks distributed in Germany directly to Interzero in equal instalments throughout the year.
2. As an alternative, you can purchase paper sacks with the REPASACK symbol from the paper sack manufacturer and pay the licence fee for the total volume bought to Interzero Repasack GmbH via the sack manufacturer.
- Where are the collection points for free paper sack take-back and what are the criteria?
A directory of the 350+ certified waste management firms in Germany with integrated collection points, plus take-back criteria, can be found in the Download area on this website.
- How do REPASACK’s paper sack recycling facilities work?
Interzero Repasack operates Europe’s only recycling facility for paper sacks in Oberhausen, Germany. At this plant, a dry mechanical process is used to shred and clean kraft paper sacks empty of usable product. This enables over 95 per cent of product residues to be filtered out of the paper fibres. These are collected in a filling plant by bulk product group before being disposed of in an environmentally friendly way, e.g. as fuel for power stations. A press is used to compact the shredded and cleaned paper fibres into bales for commercial resale. In this way, the loop is closed in the lifecycle and the paper fibres are used as a secondary raw material in the paper industry – in the manufacture of new kraft paper sacks, for example. This dry mechanical process is not used if sacks have been used to hold hazardous substances or goods that are strong colourants. These sacks are processed separately and used in energy recovery.
