Description
Post-consumer asphalt shingles (PCS) are a waste product from the demolition or rehabilitation of buildings. It is estimated that around 250,000 tonnes of PCS are generated in Quebec every year, of which only 13% are recovered as alternative fuels for cement plants. Since 2010, asphalt shingles with paper fibers have been replaced by shingles with glass fibers. The latter contain less bitumen (around 15-20% instead of 30-35%), as well as glass instead of paper, which means that the recovery as fuels is no longer possible. It is therefore essential to find a value chain for post-consumer asphalt shingles with glass fibers (PCSG) in order to circularize the value chain for this material. The aim of this research project is to assess the technical, economic and environmental potential of recycling PCSG in pavement materials.
