Nadargi, D. Philippe, K. Goiti, E. Ocejo, M. Vegas, I. Date 2017-06-21 Abstract Since the Industrial Revolution, humanity’s use of natural resources has been basically the same: TAKE, MAKE and THROW AWAY; which consequently led to the indispensable problems of waste materials. Around 461 million tons of Construction & Demolition Waste (C&DW), excluding excavation materials, are yearly generated in EU28. This undoubtedly gives a call to novel closed-loop circular business models which reshape the Eco-system in a way the waste is 'designed out'. Here, we present a novel closed-loop circular economy model of a high-performance building insulation material from silica containing C&DW materials to silica aerogels with λ≈0.015 W/mK. In the present model, the benefit comes with the use of massive construction waste to a silica precursor and thereby aerogel production guaranteeing at least 40% product cost reduction and 40% reduction in energy consumption in real construction environment.
