Welcome to a pivotal conversation on the future of our built world. The concrete industry, indispensable for modern infrastructure, is facing an urgent mandate: reconcile its foundational role (pun) with its role as a source of environmental pollution. The scale of the emissions are staggering - if global concrete manufacturing were a country it would be the 3rd largest emitter, behind only China and the US (!). The good news is that with this a motivation the global concrete industry is now rethinking its entire lifecycle.
In this episode, host Kristof sits down with John Mead, one of the founders of Solid Carbon to talk about efforts to transform concrete from a carbon emitter into a "net carbon sink. By converting waste carbon materials, wood being one, into a mass of solid carbon through pyrolysis and then using this carbon sink in a durable material through concrete we are making a huge impact in an industry that needs to make some powerful shifts in the years ahead.

The work of the AEC is broader than buildings. On a daily basis we, collectively and individually, make decisions that have broad and lasting impacts on our lives, our health, and our world. These impacts can be either positive or negative; the choice is ours. This is the perspective of Gina Ciganik and her brilliant and motivated team at Habitable.
Armed with powerful minds and compelling data, they are working to help society rethink material supply chains altogether. Formerly the Healthy Building Network, Habitable exists to help people understand that we need to fundamentally shift the materials economy to protect ourselves and our planet's ecosystems. These are also the people who created the Pharos database. Now they are releasing a powerful tool, The Informed Tool, to make it easy to make good decisions for materials using a simple Green, Yellow, Red system. It’s time to start.
If the term materials economy is somehow just a bit bland and doesn’t connect or feel engaging for you, consider these two facts to remind you of what we’re talking about:
1. Microplastics in the ocean: 58% of them are from one material - Paint. And 48% is from paint used in homes and buildings. We know latex gloves are plastic but somehow we forget that latex paint is as well. If we are going to ever get the plastics out of our waterways, oceans and bodies, we have to address this material and the upstream decision making process.
2. Carpeting as single use material: 2 Millions Tons of carpeting are thrown into landfills and incinerators in the US every year. Our national obsession with fuzzy floors uses more plastic than all single use plastic bottles, plastic bags, and plastic straws combined (mic drop).
OK, did those wake you up and help you understand that the decisions we make here in the AEC have implications and impacts far beyond what we normally consider our purview? Join Kristof and Gina in this lively wide ranging discussion as they unpack the work that Habitable is doing.
