Compostable capsule retains coffee quality

Innovative coffee capsuleThere is an increasing requirement to balance the demand for capsules with sustainable packaging solutions, according to RPC Bebo, a manufacturer of thermoformed packaging.

The company developed an innovative coffee capsule material that can be industrially composted while still deliver long-term protection of contents. It is also able to withstand the high-pressurised operation of coffee machines.

The new Bebo B2nature material features a special multilayer sheet which incorporates an effective oxygen barrier. This helps deliver a long ambient shelf-life and maintain the aroma and quality of the coffee in the capsule.

Within 12 weeks of industrial composting, a minor amount of capsule material is left owing to efficient decomposition. The decomposition is assisted by the coffee itself. It provides valuable nutrients to the compost and improves the nature of the soil. The material can therefore be certified for industrial composting, based on key European and US norms. The compostable capsule retains comparable strength and durability to one made from conventional capsule materials.

RPC Bebo’s business unit manager of thermoformed barrier packaging, Matthias Michaelis says B2nature allows consumers to benefit from the convenience of small portion packs by providing a sustainable means of disposing of them.

‘Equally important, the material also offers the high level of protection that means the freshness, aroma and quality of the coffee are not compromised,’ he concludes.
