paperChain assesses the use of industrial waste in several sectores
An industrial pavilion and a road section, both in the Aveiro region, are the first visible results at real scale of using waste generated in the pulp and paper industry in precast concrete structures and in bituminous mixtures for roads paving in Portugal. The challenge, which is both complex and ambitious, emerged as part of the paperChain European project and is already being put into practice in Ílhavo and Cacia: using waste from pulp production, such as lime ash, dregs and grits (granular waste) as secondary raw materials in the construction sector, integrating them in a circular economy logic. The paperChain project includes 20 partners from five EU countries committed to circularity boosting). In Portugal, the entities involved include the University of Aveiro, The Navigator Company, Spral, Megavia, RAIZ Research Institute and the Sustainable Habitat Cluster. Called "New niche markets for waste from the pulp and paper industry based on the circular economy", it is coordinated by the company Acciona Construction (Spain).
