Placing shredded tires on top of -- rather than in -- landfills can save money and benefit the environment, researchers from the University of Illinois say.
Timothy Stark, a professor of civil and environmental engineering at the University of Illinois at Urbana-Champaign, and Krishna Reddy, a professor of civil engineering at the University of Illinois at Chicago, recently evaluated the use of shredded tires as a drainage material in waste-containment systems. Shredding tires into chips roughly 4 inches by 6 inches, they report, offers a simple and cost-effective way of providing drainage for modern landfills, remediating older landfills, and disposing of mountains of scrap tires.
Nearly 280 million tires are discarded annually in the United States. Piles of worn-out tires can become eyesores and breeding grounds for mosquitoes. In landfills, intact tires can collect methane (produced by decomposing waste) and create potential fire hazards. Over time, these tires can work their way to the surface, where they can damage liner covers and cause increased leachate production that could contaminate groundwater.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
