European Insight: How are food-fed AD plants managing de-packaging rejects?

A challenge that looks different across Europe

Unlike digestate quality or biomethane production, there is relatively little publicly available information about how de-packaging rejects are managed across different European markets.

Practices vary depending on factors such as:

• Feedstock composition
• The type and efficiency of de-packaging equipment
• Local waste infrastructure
• National regulations
• Availability and cost of disposal routes

For some operators, rejects may be sent for energy recovery. Others may rely on mechanical treatment, drying or further separation before disposal. In some regions, landfill may still play a role, while elsewhere tighter regulations are encouraging greater resource recovery.

Understanding these differences is important, not only for individual operators, but for the wider development of Europe’s circular economy.

Beyond disposal: are we recovering all the value available?

Although de-packaging rejects are often viewed as an unavoidable by-product of food waste processing, they still contain residual organic material that has value.

Where organic contamination remains attached to packaging, it can limit recycling opportunities, increase transport costs due to moisture and weight, and reduce the overall value that can be recovered from the waste stream.

As disposal costs rise and sustainability targets become more ambitious, many operators are beginning to ask whether there are better ways to manage these materials before they leave site.

Emerging biological treatment technologies are creating new opportunities to reduce the organic content of contaminated reject streams, improving their suitability for downstream recycling or recovery while reducing reliance on disposal.

For operators, this has the potential to deliver both operational and commercial benefits, from lowering disposal costs to increasing overall resource recovery.

Building a clearer picture of Europe’s approach

As Advetec expands its work across Europe, we’re engaging with food-fed AD operators, developers, EPC contractors and technology providers to better understand how de-packaging rejects are managed in practice.

Together, we can explore how innovation is supporting more efficient operations, improved resource recovery and a stronger circular economy across Europe’s growing food-fed AD market.
