This machine, affordable at 500 USD and about the size of a breadbox, recycles household plastic into filament to use in desktop 3d printers. We want to do the same with our machine, using construction waste that we transform as much as possible on site. In part this is to limit transport costs – vital to setting up sustainable methods – but it also eliminates storage, and most importantly reuses materials currently meant for landfill.

They’re talking about us, and with us. There are a lot of really good initiatives happening in our Quebec these days. Thanks very much to Mme Côté for a lovely experience.

Sustainable building means using materials that are healthy, affordable, local, and as little transformed as possible. It might sound daunting, but most of these solutions are the simpler ways, and the older ways. They are frequently healthier and local by nature.
Please consider sharing this among your Francophone contacts: these architectural and passive solar design principles reduce the energy costs of a home enough to nearly eliminate heating and cooling costs, even here in Quebec. People should know, and insist that their developers know, too.

Material selection becomes simpler with this 3d printing geometry developed by MIT, a bit by accident. See the video for the likely structure of our walls. 🙂
« The same geometry could even be applied to large-scale structural materials, they suggest. For example, concrete for a structure such a bridge might be made with this porous geometry, providing comparable strength with a fraction of the weight. This approach would have the additional benefit of providing good insulation because of the large amount of enclosed airspace within it.”
