Mondi has co-founded a Spanish alliance to improve used paper bag circularity in the construction industry. The alliance, Paper Sacks Go Circular Spain, comprises 12 European companies from the full value chain, including Mondi. The initiative follows Mondi’s summer launch of a dissolvable cement bag to the Spanish building industry. SolmixBag is a one-ply paper bag made from 100% kraft paper that stores and transports dry cement, screed and coarse pre-mixes. It disintegrates during mixing, eliminating dust and waste on the building site.
