Landfills emerge as promising battery storage sites to back up renewable energy

via WasteDive.com

Solar panel installations have been one of the fastest-growing types of energy infrastructure in recent years and landfills have become fitting sites due to the sheer amount of land required. Now, for many of the same reasons, energy project developers are looking to landfills for a technology growing even faster than solar: battery storage.

Storage on landfills is still a novel idea, with closed sites seen as largely the most suitable, and only a few examples of these projects exist. But solar on landfills was in a similar position just a few years ago, Tim Ryan, director at New York-based developer BQ Energy, told Waste Dive. BQ Energy focuses specifically on brownfield sites and has built over a dozen solar or wind projects since 2012, but only recently began construction on its first storage venture. Solar on landfills “may seem routine now, but it wasn’t when we started,” Ryan said.

MIT students fortify concrete by adding recycled plastic

via MIT NEWS

Adding bits of irradiated plastic water bottles could cut cement industry’s carbon emissions.

MIT undergraduate students have found that, by exposing plastic flakes to small, harmless doses of gamma radiation, then pulverizing the flakes into a fine powder, they can mix the plastic with cement paste to produce concrete that is up to 20 percent stronger than conventional concrete.
