Sustainability: The cement in concrete is derived from heating limestone, which is a carbon-intensive process that creates gas emissions. However, slag cement, fly ash and silica fume — all industrial waste by-products that are carbon neutral — can replace more than 50 percent of the cement, reducing emissions and improving the concrete’s ecofriendliness.
I recently learned that several universities now offer advanced degrees in Environmental Decision Making. I’m not surprised. Even after years of practicing sustainable design, I still find that sussing out the best green products can be challenging. There are many environmental factors to consider, plus there’s a constant barrage of new, better, greener products. So, save for signing up for a postdoctorate program, what’s a guy or gal to do?
