"Of mice and monitors: The science of green tech ratings systems"

Two Democratic U.S. Senators -- Amy Klobuchar of Minn. and Kirsten Gillibrand of New York -- introduced earlier this month legislation aimed at funding R&D efforts to improve to recycle e-waste and develop best practices and innovation in greener design of electronics. The Electronic Device Recycling Research and Development Act, a nearly identical version of which passed the U.S. House of Representatives in April, provides almost $85 million over the next three years to help spur the growth of electronics recycling practices in the U.S. The bill, S. 1397, includes four main initiatives: providing grants for R&D into e-waste processes and practices, funding research into environmentally friendly materials for use in electronics, establishing educational curricula for engineering students at all levels to incorporate green design practices into electronics, and publishing a report from the National Academy of Sciences laying out the good and the bad in the current state of electronics recycling.

E-waste comprises discarded electronic appliances, of which computers and mobile telephones are disproportionately abundant because of their short lifespan. The current global production of E-waste is estimated to be 20-25 million tonnes per year, with most E-waste being produced in Europe, the United States and Australasia. China, Eastern Europe and Latin America will become major E-waste producers in the next ten years. Miniaturisation and the development of more efficient cloud computing networks, where computing services are delivered over the internet from remote locations, may offset the increase in E-waste production from global economic growth and the development of pervasive new technologies.

Trash Track relies on the development of smart tags, which will be attached to different types of garbage in order to track in real time each piece of waste as it traverses the city's sanitation system. The goal of the project is to reveal the disposal process of our everyday objects and waste, as well as to highlight potential inefficiencies in today's recycling and sanitation systems. The project will be exhibited at the Architectural League in New York City and in Seattle starting September 2009. MIT SENSEable City Lab project; this is the project web site.

The real-time city is now real! The increasing deployment of sensors and hand-held electronics in recent years is allowing a new approach to the study of the built environment. The way we describe and understand cities is being radically transformed - alongside the tools we use to design them and impact on their physical structure. Studying these changes from a critical point of view and anticipating them is the goal of the SENSEable City Laboratory, a new research initiative at the Massachusetts Institute of Technology.

The blog for MIT's SENSEable City Lab Trash Track project.

Scientific American, 7/17/09, article by Larry Greenemeier. Most people assume that their trash ends up in a landfill somewhere far away (if they think about this at all). But growing concern over the environmental impact of waste-discarded electronics, in particular-has prompted a team of researchers at the Massachusetts Institute of Technology (MIT) to take a high-tech approach to studying exactly what people are tossing out and where those items are ending up. The researchers, part of MIT's Senseable City Lab, have developed electronic tags that they're hoping as many as 3,000 volunteers in Seattle and New York City will affix to different items they throw away this summer as part of the Trash Track program. These tags will contact cell phone towers they pass as they flow through the trash stream to their final destinations, helping the researchers monitor the patterns and costs of urban disposal.
