Across Europe and the United Kingdom, more than two million hospitality businesses handle substantial volumes of glass packaging. On average, each establishment generates around 1.5 tonnes of glass waste annually, underlining the sector’s relevance for material recovery.
Collection Potential and Market Differences
The hospitality sector accounts for an estimated 17% of the total glass recycling potential in Europe, according to a 2022 study commissioned by Close the Glass Loop. In some countries, the share is considerably higher. Greece reaches up to 78%, while Portugal and Spain report 39% and 36% respectively. In contrast, markets such as Germany, Poland and the Netherlands show lower shares of one-way glass in HORECA, reflecting a higher prevalence of reusable systems.
These variations highlight the need for tailored collection systems that consider operational conditions such as limited storage space, high throughput and frequent waste collection requirements.
Operational Challenges in Glass Collection
Despite increasing attention to separate waste collection, maintaining high-quality glass recycling in HORECA remains challenging. In daily operations, glass packaging is often handled alongside other materials, which increases the risk of contamination.
After collection, glass packaging is processed into cullet for remelting. However, the presence of ceramics, stone and porcelain (CSP) can disrupt recycling processes. Such contaminants may damage furnaces and reduce the quality of newly produced glass containers. The risk is particularly high in hospitality environments, where glass and ceramic items are used simultaneously.
Measures to Improve Recycling Quality
Effective glass recycling in HORECA depends on both system design and staff awareness. Collection systems must be practical and adapted to fast-paced working environments. At the same time, targeted training and awareness measures are required to ensure correct separation practices.
To address these issues, Close the Glass Loop has launched a Europe-wide awareness campaign in cooperation with HOTREC. The initiative focuses on improving both the quantity and quality of collected glass packaging by promoting correct separation and reducing contamination risks.
The campaign emphasises the role of hospitality businesses in maintaining closed material loops for glass packaging and supports the sector in meeting recycling targets.
