DOE Invests $13.4 Million to Combat Plastic Waste, Reduce Plastic Industry Emissions

by

via Energy.gov

The U.S. Department of Energy (DOE) today announced $13.4 million in funding for next generation plastics technologies that reduce the energy consumption and carbon emissions of single-use plastics. The seven selected research and development (R&D) projects — led by industry and universities — will convert plastic films into more valuable materials and design new plastics that are more recyclable and biodegradable. This investment advances  DOE’s work to address the challenges of plastic waste recycling and supports the Biden Administration’s efforts to build a clean energy economy and ensure the U.S. reaches net-zero carbon emissions by 2050.

Doosan outlines plan to produce hydrogen from plastic waste

by

via GlobalConstructionReview.com

South Korean equipment maker Doosan Heavy Industries has signed a memorandum of understanding with another Korean company to develop the technology to produce hydrogen from waste plastics and vinyl.

Doosan has teamed up with RevoTech, a plastic pyrolysis specialist, to carry out the work. RevoTech will handle the thermal decomposition of the plastic waste to produce gas, and Doosan Heavy will develop facilities and processes to extract hydrogen from it.

Catalyst turns mixed plastic waste into natural gas

by

via Chemistry World

Plastic waste can now be efficiently converted into methane using a ruthenium-based catalyst. The patented technology could help mitigate the planet’s growing plastic waste problem while producing methane for use as a fuel or chemical feedstock in a more environmentally friendly way than fracking.

Recovering chemicals and fuel from plastic waste streams is nothing new. Processes including pyrolysis and gasification, which break down plastics using high temperatures and catalytic processes, can recover useful materials. However, these approaches create several products, including waste, and require additional processing and purification.

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

    by

    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.

    Why polymer solar cells deserve their place in the sun

    by

    via EurekAlert

    Polymer solar cells may lag behind traditional silicon solar cells in longevity and efficiency, but could ultimately power autonomous remote sensors and wearable technology.

    Unlike traditional silicon solar cells, organic polymer solar cells (PSCs) may never cover the hillsides of a megawatt solar farm. But, these lightweight, flexible cells show potential to provide solar power to remote microwatt sensors, wearable technology and the Wi-Fi-connected appliances constituting the “internet of things.”
