For the love of nature

Vinolok’s commitment to sustainability drives all parts of the glass production and delivery.

Vinolok Sustainability - Glass is the best

Glass is the best

Glass is known worldwide as not only the safest for food and beverage packaging, but also the safest for the environment. It can be infinitely recycled and refilled without losing clarity, purity or quality. This makes glass the archetype of sustainable packaging and as such it is usually the first choice for environmentally conscious consumers.

Responsible sourcing

The glass closure is made from the best raw materials from local sources. Over 70 % of the materials for the batch comes from within 40 km of the glass furnace. Preparing the right mixture is essential to maintain 100% glass quality.

Glass recycling reduces energy use and preserves natural resources – creating a sustainable loop that benefits the environment and future generations.

Current situation

Vinolok champions global glass recycling, breathing new life into materials while reducing resource consumption and pollution. Recycled glass production, such as Vinolok closure, lowers air pollution by 20%, water pollution by 50%, and minimizes landfill space, aligning with circular economy principles to capture lost value and save raw materials, energy, and carbon emissions.

Future plans

In line with a sustainable future, Vinolok plans a comprehensive study by 2030, focusing on innovations in glass closure production, with a strong commitment to increasing recycled glass content for enhanced environmental impact.


Upcycling reduces the overall environmental impact and contributes to a “green” mentality and more sustainable lifestyles overall.
Reduce - Reuse - Recycle

The life cycle of a Vinolok™ glass closure could be unlimited. Upcycling means turning a product into something useful and often beautiful, which can happen with a glass closure and a bottle. In this way, we can work together to support creativity and, at the same time, be friends of our planet.

Upcycling reduces the amount of materials and products sent to landfill. It also minimises the use of natural resources and raw materials. As a result, upcycling leaves a smaller footprint, reduces consumption, and minimises the impact on valuable resources such as fuel, forests, and water supplies.

Keep it green

The carbon footprint provides a measure of a product’s environmental impact. By quantifying a product, we can understand its contribution to climate change and environmental degradation. By incorporating carbon footprint considerations, we can move towards a more sustainable and environmentally conscious future.

Packaging and shipping

Product packaging and shipping is an integral part of a reliable and safe product for Vinolok™. The 100% safe and hygienic product delivered to the customer is our priority at all times.


The cardboard box in which  closures are delivered is made of recycled material (68%) and is suitable for further recycling after use. The surface is made of primary fibre to ensure the packaging hygiene.


The trays, which hold the closures in place during transport, are made of PET three-layer foil. The inner layer, which represents 80% of the total blister thickness, is made of already recycled PET material. Both outer layers are made of virgin PET material and thus meet the specifications for food contact material. The entire tray is completely recyclable.


The pallets used for shipping the boxes with Vinolok™ closures are 100% reusable.

Quality is our must principle

One of the main objectives of the Vinolok company is to provide customers with high-quality products and services. Every single glass closure passes 100% quality check four times during the production process and therefore Vinolok™ is a guarantee of securely sealed beverage. In order to satisfy customers‘ existing and future product quality and safety requirements, the Vinolok company has established an Integrated Management System with the application of modern management principles and international standards.
