About Ductor

Ductor started in 2009 with the ambitious aim to create a solution that would help solving today’s environmental challenges in the energy and agriculture sector. Today we build, own, and operate microbiological turnkey facilities, turning waste from the agricultural sector into sustainable fertilizers and biogas. With two plants in Mexico and Germany and numerous projects in the pipeline we could proof that we are able to live up to our purpose:
We are unlocking bio-resources to make food sustainable and energy clean.

Vision & Mission

We strive to be the sustainable leader in biogas and fertilizers.

We repurpose organic resources and put them back to work as carbon reduced fertilizers and renewable energy.
