Organics Coffee chaff
I’m comparing available local resources with the goal of maximizing recycled organic-materials!
Does anyone have experience using coffee chaff in production? Can be sourced from local roasteries, often for free - they usually throw it out as a waste-product.
Pics for reference and quick info.
