About US & Commercial Composting Solutions
Turning the World’s Food Waste Into a Circular Resource
OUR STORY
Built on One Principle: Waste Nothing
3R Urban Solutions was founded on the conviction that organic waste is not a problem — it is a misplaced resource. Every tonne of food that ends up in landfill could instead be enriching soil, growing food and sustaining ecosystems for future generations.
Our machines embody the three principles that give us our name. Reduce — the volume and cost of waste leaving your site. Reuse — convert waste into a valuable soil amendment used directly on your grounds. Recycle — return nutrients to the soil where they belong, closing the loop completely.
“We don’t inherit the earth from our ancestors. We borrow it from our children.”
Having established ourselves as one of Asia’s leading composting machine manufacturers with over 700 installations globally, we have expanded to the UK and Europe — bringing the same proven Schnell Komposter technology to organisations committed to genuine, measurable sustainability.
