About the project
The paperChain Project “New Niche Markets for the Pulp and Paper Industry Waste based on circular economy approaches” intends to demonstrate the technical and environmental feasibility (TEF) of using different residues—generated in the Pulp & Paper Industry—as secondary raw material, with the aim of becoming competitive substitutes for the primary raw materials in near future.
This Project includes five large-scale demonstrators or demo-cases in different operational environments: Construction in Portugal (asphalt mixtures and concrete in roads), Spain (stabilised-soil layers in roads) and Slovenia (composite materials for slide stabilization in railways); Chemical in Sweden (bio-ethanol for secondary chemicals); and Mining in Sweden (sealing layers for reactive spoil).

Valorisation of Paper industry’s causticizing residuals (i.e. lime mud, slaker grits and green liquor dregs) as secondary raw materials for concrete and asphalt manufacturing.
Lime ash as concrete filler; slaker grits and dregs as aggregates for asphalt pavements.
