Close the Glass Loop Publishes the Principles for Good Bottle Bank Collection of Glass Packaging

In a major step toward achieving a fully circular glass recycling system in Europe, Close the Glass Loop has published its new document: Principles for Good Bottle Bank Collection of Glass Packaging. This comprehensive guide serves as a reference framework for practitioners to optimize the performance of the continent's most common collection model.

The Importance of the Bottle Bank

The monomaterial municipal bring-back system, or "bottle bank," is the predominant collection method in 21 EU Member States and is widely considered the most cost-effective and preferred method for recycling facilities. Because the quality of the collected glass directly determines how much can be used in new production, the practices used at these collection points are vital for reducing energy consumption and the need for virgin raw materials.

Key Recommendations from the Study

The study outlines evidence-based guidance across three critical stages:

Collection: Ensuring bottle banks are conveniently located (recommending one per 300-550 inhabitants in urban areas), clearly labeled with prohibited items like porcelain, and regularly maintained to encourage participation.
Transportation: Adopting the "golden standard" of handling glass exactly as it was deposited. This includes using suitable vehicles, avoiding compaction trucks that cause excessive breakage, and optimizing routes through smart technology.
Storage: Using adequately sized, paved storage bays that are securely separated from other waste streams to prevent contamination from dirt or stones.

A Multi-Stakeholder Approach

The principles are the result of extensive consultation with 13 national platforms, recycling facility operators, and industry experts. While non-prescriptive, they provide a roadmap for municipalities and operators to adapt to their local contexts while maintaining high material standards.

Looking Forward

By prioritizing minimal breakage and contamination, European stakeholders can strengthen the closed-loop system and work toward the common goal of collecting 90% of all glass packaging for recycling by 2030.
