«We decided not to use compounded materials to avoid issues with THF migrations and aging. CAPSULE DESIGN We learned that all the elements of the system are related. When we switched from PP to PLA in our thermoforming process we had to reconsider all the elements to be able to provide a solution» LID SOLUTION MATERIALS PP PLA unit Specific Gravity 0,90 1,24 MFR 4 8 g/10 min HDT (0,45 Mpa) 106 54 C Shrinkage 1,5 2,5 0,3 0,4 % BREWING MACHINE COFFEE

The result is a new generation of coffee capsule developed with NatureWorks made with Ingeo PLA

Compostability All the raw materials used to produce GEA are certified for industrial composting system according to global standards such as EN 13432 (EU) and ASTM D6400 04 (USA). The new capsule is now in final testing by TÜV Austria and the Italian Composting and Biogas Association (CIC) for the compostability certification. EN 13432:2000 Norm Requirements for packaging to be recovered by composting or bio degradation 3. No negative effects on composting process 2.Disintegration 90% disintegrated in fragments < 2mm in 3 months 4.Eco toxicity and compost quality Heavy metals, volatile solids, N, P, K, Mg, PH, salt composition can t be deviate from the reference compost 1.Biodegradability 90% into CO2 and H2O in 6 months COMPOSTABLE
