How LOOP works
Four steps
between neighbouring towns.
01
Register
Each city or town runs its own node and joins the federation.
02
Offer
Nodes list surplus secondary materials, such as reclaimed timber or excavated soil.
03
Match
Offers are matched with demand from nearby nodes.
04
Transfer
Agreed transfers are recorded with material data that fits Digital Product Passports.
The URBNIA platform
One platform.
Five modules.
Each module works on its own and fits with the others.
