Gronbla Circular Composting


100% Plant-based and 100% compostable

Our goal is to produce as little waste as possible through sustainable concepts and the highest possible proportion of biologically produced, compostable materials, and at the same time also to preserve our world’s resources.

The further increase in environmental pollution calls for a fundamental rethink in raw materials, production and use, with the goal of a new circular economy. We are taking the first steps and thinking in new biological and environmentally compatible solutions. Join us! Together we can change the world.

For us, avoiding unnecessary packaging is just as much an essential goal as using renewable raw materials and biodegradable and compostable materials. Together with our customers and partners, we want to set the standards.


Bury your used product in a compostable environment, which could be a garden or food waste machine. The products are decomposed in 60 – 90 days into organic carbon, fertilizer and thus returned to the Earth: A great solution for our planet!


Compostable materials are made from polymerization of plant-derived building blocks; this is in contrast to conventional plastics which are made from fossil fuels. So compostable materials are more environmentally friendly than traditional plastic.


Our compostable materials can be fully biodegraded by microorganisms in composting facilities or your garden. The material is degraded into organic carbon, which can be used as fertilizer to nourish and grow plants.
