Our service for waste management companies

Do you have questions about collections, sorting or mass flows relating to the Interseroh+ dual system?

As the Interseroh+ dual system (DSI+), we are active nationwide in the collection, sorting and recycling of used sales packaging as stipulated by the Act to Improve the Separate Collection of Recyclable Household Waste (German Packaging Act, VerpackG), subcontracting these activities where necessary to waste management companies, sorting plants, logistics firms and recycling plants throughout Germany. These contracts are awarded by formal calls for tender and are financed by the participation fees paid by those producers who are the first to place packaging filled with goods on the market.

The used packaging is collected either directly from private households or locally to these consumers (e.g. from a recycling centre), or from a combination of these two variants. The packaging to be collected is separated into lightweight packaging (LWP, e.g. yellow bag/bin), glass (e.g. bottle bank) and PPC (e.g. paper container).

Sorting plants then further sort the lightweight packaging collections into recyclable materials (e.g. plastics such as PE). Separation may be manual or completed by a mechanical process that utilises various optical and electronic detection systems. Compressed-air jets and magnetic separators are used to route the individual waste fractions along sorting belts into sorting hoppers. This targeted approach to separation ensures a wide variety of recyclable fractions can be used as input for recycling processes. This creates secondary raw materials that can then be used to manufacture new products.
