Bitumen not yet feasible for high-grade processing. High-grade processing of bitumen dropped out as a case: it turned out not to be feasible yet, practically or in cost terms, because of the purification technology required. Hidden value is lost in construction and demolition residues through downcycling.
Open databases and calculation models make that value visible and keep material in high-grade use. This outcome is relevant for construction and demolition companies, municipalities and organisations in circular construction. Source: Urban mining MRA (2018).
