Have building-size legos finally arrived?
The Institute for Civil Engineering and Environment (INCEEN) at the University of Luxembourg have signed a "memorandum of understanding" with the Suisse Federal Laboratories of Materials Science and Technology (Empa) of the domain of ETH Zürich to collaborate on research on energy efficiency in the construction sector.
As the building sector is generating a large amount of CO2 emissions, resource consumption and waste production, new eco-construction approaches are needed. Therefore, the first collaboration project entitled "Eco-Construction for Sustainable Development" (ECON4SD) will focus on the development of novel components and design models for resource and energy efficient buildings based on the construction materials concrete, steel and timber.
ECON4SD will bring together researchers from different civil engineering fields and architecture at the University of Luxembourg and the Empa Zürich, as well as from universities abroad in cooperation with partners from industry and consultancies in Luxembourg. One vision of the project is to develop building components that can be re-used after a building has reached the end of its life cycle and is disassembled. "The ECON4SD aims to turn buildings into materials and components banks and will allow producers of structural elements to come to a different business model. That would consist in loaning materials or components to customers and take them back after use in a particular building, in order to resell them directly, recondition or recycle them," commented professor Danièle Waldmann of the University of Luxembourg. "Thereby, the project paves the way for a future CE material or component passport comparable to the already existing energy passport."

At best this stuff ends up being used for is Fill. (Building "pads" upon which new buildings are build.
Yeah, that's what I'm talking about. I wasn't claiming that old concrete was broken up and used for new, high-quality concrete. But being used for fill is a form of recycling, and a good one at that: not all applications require high performance; a cheap, lower-performance recycled material may be a good alternative.
Similarly, when drink bottles are recycled, they aren't used to make new food-grade plastics. Instead, they're used to make lower-grade plastics for things like picnic tables and park benches and boardwalks. That plastic lumber is great stuff, compared to real wood (it doesn't dry-rot and split after a few years in the elements), but needs a lot of material, but it doesn't need to be ultra-pure high-quality stuff.
