Every municipality is a material bank.
Dutch municipalities hold billions in buildings, roads and land — value recorded on public balance sheets, and material value hidden inside it. Select a municipality and see what a circular approach could unlock.
From balance sheet to material value.
Official open data
Every quarter, all Dutch municipalities report their finances to CBS under the IV3 standard. We read the audited year-end balance sheet (jaarrekening, ultimo positions) directly from the CBS OData API — no scraping, no estimates on the input side.
Isolate the built structures
Only assets that physically contain materials count: buildings, residential property, civil works (roads, sewers, bridges) and installations. Land, vehicles and other non-structure posts are shown but excluded. Book values are depreciated, so they systematically understate the real material stock.
Indicative recovery factors
We apply per-asset-class material-recovery factors to estimate circular value potential. The factors shown here are placeholders for illustration. MAECONOMY’s team replaces them with audited, material-level calculations — track, trace & transact.
Want the real number, not the indication?
Onboard your portfolio and turn buildings into certified, tradable material reserves — visible, auditable and part of a global circular economy.
