Onnu Ltd

Onnu Biochar manufactures consistent, reliable, high-quality biochar at scale for trade and commercial customers looking to enhance soil and growing media products.

Our UK manufacturing site sustainably sources waste wood and produces high quality pure biochar, which can be supplied in bulk, or mixed with compost depending on customer requirements.

Our approach goes beyond manufacturing - we collaborate with various environmental specialists to optimise biochar's use.

Our mission is to foster a greener, more sustainable world, with every biochar delivery bringing us closer to this goal.
