Ting London makes bespoke flooring out of recycled leather belts, laying them down like floorboards. When/if you get sick of them, they'll take them back and recycle them. I'm not sure how they'd wear or what they'd be like to clean, but they look awesome.
Each belt is hand selected to ensure a high grade of leather and then the belts are stripped of their metals, hand cleaned with chemical free substances and prepared for use. The vintage belts for each tile are carefully designed in-house as the colour and patterning on the belts is sensitive to each tile. This means no two tiles will ever be the same.
