industry tools and guidelines

At the 4evergreen alliance, more than 350 experts from across the fibre-based packaging value chain collaborate to develop science-based guidelines and recommendations for fibre-based packaging that is compatible with a low-carbon, climate-neutral society.

Each technical workstream has already made significant progress in achieving their goals. Here you can find the reports, protocols, and guidelines released. Each is the culmination of science-led research and discussions.

As a starting point, the alliance aimed  focused on  ‘standard’ mill capabilities, thus tackling the largest chunk of fibre-based packaging.

Members are already working intensely on updated versions of these documents, which will include recommendations for fibre-based packaging that require reprocessing in specialised recycling or deinking facilities. These living documents will be updated as industry knowledge progresses.

European Harmonised Laboratory Test Method (October 2022)

4evergreen experts worked on three technical annexes for Cepi’s European Harmonised Laboratory Test Method. Using this method, results from lab tests can provide data to be inserted on the Recyclability Evaluation Protocol’s scorecard, which will then calculate a recyclability score for the material tested.

The annexes include a Detailed Work Description for the testing method, a Lab Report Template and a ‘Decision Tree’ to assess visual impurities.

Recyclability Evaluation Protocol: part one for standard mills (December 2022)

The Recyclability Evaluation Protocol beta release is ready to be used to evaluate individual fibre-based packaging products and score their suitability for recycling in standard mills.

The whole sector is encouraged to test the evaluation protocol and send their feedback to optimise this beta release into a first completed version.

Upcoming publications

• Recyclability Evaluation Protocol: part two deinking mills (expected Q4 2023)
• Recyclability Evaluation Protocol: part three specialised mills (expected Q4 2023)

Circularity by Design Guideline for Fibre-Based Packaging (March 2022)

This document is the first in a three-part series, and is intended for designers and manufacturers to evaluate the compatibility of materials and components with standard mill processes. It is applicable to fibre-based packaging design that is likely to be recycled in standard recycling mills, provided that product-specific regulations of the packaging are observed.

Upcoming publications 

Recommendations on the suitability of specialised recycling processes (UBC mills) – expected June 2023
Recommendations on the suitability of floatation -deinking and additional specialised recycling processes – expected 2024

Guidance on the Improved Collection and Sorting of Fibre-based Packaging for Recycling (September 2022)

This guidance is based on a review of the institutional frameworks and different collection and sorting systems in European countries.

It offers an overview of existing systems and practical recommendations for enhancing collection and sorting of different types of fibre-based packaging. Understanding these processes is a prerequisite for recycling and treating fibres in a way that does not compromise their quality. The document is primarily focused on household collection of fibre-based packaging.

Upcoming publications 

An amended version of the guidance, including new industry findings, will be released in 2023.

Innovation is at the heart of the 4evergreen alliance and innovation workstream members are conducting several tests to leverage a range of new technologies to raise fibre-based packaging’s overall recycling rate. The group has initiated three main projects, namely:

• Sortability of Fibre-barrier Packaging
• Novel Recycling Technologies
• Comparative Recyclability Impacts
