Think about your dishwasher. You load it, set it, and close the door. Then for the next 2 hours, give or take, the device runs through phases that require large amounts of water and energy to heat, wash, rinse, and dry. And a lot of that water and energy being used is overkill, it’s wasteful, and it’s all happening behind closed doors.Now, this episode isn’t about dishwashers or even home appliances. But the dishwasher analogy illustrates what occurs with process manufacturing, a branch of

We talk a lot about circularity, circular systems, circular economies, and so on. It sounds great. It may even conjure images of the now-ubiquitous recycling symbol, with its three folded arrows running clockwise in triangle formation. Some may not know that that symbol was designed by an American architect named Gary Anderson, while he was a student at USC, and that was his winning submission in a competition sponsored by the Container Corporation of America.That brief history lesson aside,

The built environment has a 600-million-ton waste problem. onstruction and demolition (C&D) waste - comprising large volumes of concrete, wood, drywall, glass, and even furniture - significantly contributes to landfill volumes, with approximately one-quarter total waste generated in the U.S. ending up in landfills. It is worth noting those figures come from reports that are selectively submitted to the EPA by state and local governments, and much of the data are more than a decade old. So, while

Baie Verte, in north central Newfoundland, Canada, is one of several communities that comprise the island’s Emerald Zone. In the 1950s, a large deposit of asbestos was discovered, and Baie Verte (French for “Green Bay”) was quickly transformed into a company town, with a large-scale asbestos mining operation that supported the community for the next three decades.Trina Barrett grew up in Baie Verte.

When we think about wood products and our domestic forests that supply them, we arrive at mental images of large swaths of forestland that populate the Pacific Northwest or the Southeast; those places that provide abundances of Douglas fir and spruce and southern yellow pine, but we rarely consider urban forests.Urban forests are critical components for keeping our cities cooler and safer. Street trees, city parks, arboretums, and the like help with stormwater management, restore biodiversity, and

Supplementary cementitious materials, or SCMs, have completely transformed the global cement industry. Where Portland cement once enjoyed a near monopoly in the industry, it’s now rapidly losing market share to all kinds of blended solutions using SCMs, which replace a large percentage of the cement clinker – that’s limestone and clay, cooked in a kiln at a balmy 1500 degrees Celsius – that goes into making concrete. The biggest examples of SCMs are fly ash, which is the byproduct from coal mining,
