The Greening of Civil Infrastructure

Similar progress is being made by manufacturers such as Unilever, a global brand leader in food, personal healthcare and other consumer products. In 2013, 75 percent of the company’s manufacturing sites brought their delivery of nonhazardous waste to landfills down to zero. Included among Unilever’s wide array of global waste recovery, recycle and reuse initiatives is the use of overflow plant sludge in prefabricated construction products and as an alternative raw material in cement production.

Increasingly, the waste generated from the manufacturing processes of companies like these and others is also finding its way into major infrastructure projects throughout the nation. The byproducts from manufacturing, as well as other industrial processes such as energy generation, offer a valuable resource for use in civil infrastructure.

Examining Sustainability at DFW Airport

“Look at iPads for example. We have them out in the field; all our contractors have them. The estimate is some $5 million savings in paper from plans that don’t have to be produced in paper every week.” Good article about green initiatives at a Dallas Fort Worth airport. Unfortunately in annoying format. Sustainable Construction, 2012


BoDean’s Quarry Is The 1st To Go Solar

“Why did BoDean decide to go with solar power? “It costs a tremendous amount of money each year to power our motors, crushers, screens, conveyors, pumps and dewatering system,” says Williams. “Energy costs keep going up and will continue to do so. It made sense to us to switch to using renewable sources for our power via photo-voltaic solar and stabilize our costs. This switch will save money, have a positive effect upon cash flow, and reduce our carbon footprint by over 900 tons of greenhouse gas emissions (GHG) per year.””  You can’t run an operation as energy-intensive as a quarry on solar, right? Well… FCP, June 18th, 2012


Green Goes Nationwide

“The business climate in America is starting to see some major changes as more and more companies are beginning to understand the important correlation between the economy and the environment.

The U.S. Chamber of Commerce continues to fight climate change policies that inhibit innovation, sustainability, and regulating harmful carbon emissions. Frustrated by these policies, major companies such as Apple, Microsoft, PG&E and Nike – to name a few – have even left the agency outright, while a huge proportion of American businesses remain excluded completely. But with a burgeoning green sector sweeping the nation, the need for a new kind of chamber of commerce has become more apparent now than ever.

That’s where the U.S. Green Chamber of Commerce comes in.” The ‘Green’ Chamber of Commerce? That’s a thing? Energy & Infrastructure


Tennessee city to implement PHG Energy’s innovative waste-to-energy system

“PHG’s biomass gasification waste-to-energy system will be built adjacent to the wastewater treatment plant on city-owned property, converting approximately 12 tons of waste per day, primarily composed of woody biomass, into energy.” Brief look, with some numbers, at a biomass project partially funded by grants. Public Works, July 26, 2012


Sustainable Infrastructure Rating System Unveiled

“The holistic approach of Envision provides a complete framework of assessment, covering all major civil infrastructure project types, scales, contexts, and project phases.” A rather dull press release but, who knows, maybe Envision will amount to something in the extremely hot sustainability space. It’s a product of the “The Institute for Sustainable Infrastructure (ISI) in collaboration with the Zofnass Program for Sustainable Infrastructure at the Harvard University Graduate School of Design,” but Ivy League involvement doesn’t automatically mean it’s useless.
