Description

While production of solid waste is increasing following population growth, in France energetic valorization by incineration is one of main solutions for treatment. The reason is that incineration reduces 70% of waste mass. Every year Lyon city transforms 60% of its household waste production into 70 000 to 85 000 tons of rubbish ashes. This huge amount of ashes causes storage problems and high cost treatment. The paper presents an analysis of an experimental study driven by architecture school to recycle rubbish ashes into construction materials. The research reports different perception of rubbish ashes among the various partners involved. Industrialists consider it as a new economic resource while construction builders and municipal services see “a filthy and polluted waste”. However, the investigation also shows that the production of new construction materials with recycled rubbish ashes requires a permanent adaptation of process that is easier to manage for handcraft builders than industrialists due to the impossibility of standardization. This paper tries to link architectural and anthropological researches by questioning professional, economical and symbolical dimensions of practices in construction industry regarding to recycling waste.
