Recycling Challenge: Construction Waste

FACT

Building-related construction and demolition waste totals approximately 170 million tons per year, roughly two-thirds of all non-industrial solid waste generation in the U.S.

PROBLEM

Total annual construction and demolition waste (“C&D waste” in the biz) equates to 3.2 pounds of building-related materials per person in the U.S., per day. According to the U.S. Environmental Protection Agency, 52 percent of this ends up in a landfill. Sources of building-related C&D debris in the waste stream include demolition (approximately 48 percent of the annual waste stream), renovation (44 percent) and new construction (8 percent). It is economically viable to recycle the majority of this waste, as the cost to transport and dispose of C&D waste can be more than 2 percent of a project’s cost.

Transitioning Town

North Philly changes before our eyes
by Will Dean with additional reporting by Dana Henry


When you think about a sustainable city, what does it look like? Whether it’s a futuristic, shiny sci-fi wonderland or a green treehouse-like Ewok village, you probably don’t think of North Philly. With it’s abandoned industrial buildings and bad reputation for drugs and crime, it doesn’t seem like the place where a bright new future full of efficient gadgets and green spaces will emerge. That kind of thinking is a barrier, though, because it’s exactly in those kinds of places that local sustainability can emerge, and on February 4 the Fishtown, East Kensington and Old Richmond sections of North Philly made a step towards becoming the most sustainable section of the city, and perhaps even the country.
