This depends on the composting environment. Thinner and softer products, like coffee cups and card containers will break down faster than denser and stiffer products, like cutlery, clear cups and coffee cup lids. Our products have passed EN 13432 standards and achieved OK to Compost verification. Under the required breakdown conditions, an approved commercial composting facility, at least 90% of the card and soft PLA lined materials will disintegrate within 3 months and 90% of the denser materials will biodegrade within 6 months (after which 100% biodegradation occurs). The resulting compost will not be adversely affected by any additional materials (such as food dyes or paper etc.) and safe plant germination is assured.
