Reclaim responsibility

We believe that people want to take back responsibility and fight climate change locally and are willing to do so wherever they live, work or enjoy life.

Working in harmony with nature

We believe in nature’s own composting process without accelerators nor additives producing a mature compost. We believe that eating ‘slow food’ is healthier for our bodies and composting leftovers slowly is healthier for Mother Nature. Our natural process gives you the most mature compost that recovers depleted soils. There is no need for chemical fertilizers, use your own compost.

Reclaim ownership

We believe that decentralized solutions are the best way to make our world sustainable. Our flexible small scale systems allow you to control the input and by that the quality of the compost.

Reduce your carbon footprint

We believe that everyone, individual and organisation alike, must contribute by reducing their CO2 emissions. Composting food waste on-site has a huge positive impact on our planet. 

Product range
from 75 to 10 800 kgs per week

Stop wasting food

  • The little food waste that remains – treat it as close to the source as possible and produce compost of the highest quality.
  • We believe in creating systems that minimizes food waste. 

Help Mother Nature recover

We believe in bringing back organic matter to help Mother Nature recover. Our compost will optimize the function of the soil and restore depleted soils.
