About Jarðgerðarfélagið

Jarðgerðarfélagið ("YARTH-gehr-thar FYEH-lahg-ith") composts organic material from municipalities, companies, and individuals, via the bokashi method. We believe that composting is a necessary part of the circular economy, and that it should be widely accessible.

Our goal is to build healthy natural and social ecosystems. Our approach to this goal is twofold:

1) Redirecting organic raw materials from landfills to local composting facilities

2) Utilizing the resulting compost as a nutritious fertilizer for land reclamation, agriculture, and gardening

"Food waste" is a valuable resource, and ensuring that it's used to its fullest potential requires reframing how with think of and interact with it. As we expand our efforts, we do so with a guiding principle of empathy and cooperation. Composting should not be stressful or difficult — in fact, we think it's rather fun.
