University of Illinois at Urbana-Champaign Research Reduces Microprocessor Serial Link Power Consumption, Improves Data Center Energy Efficiency
University of Illinois at Urbana-Champaign researchers are working to reduce the serial link power consumption, thereby helping data centers and mobile platform operate more energy efficiently.The University of Illinois research--sponsored by Semiconductor Research Corporation (SRC) through the Texas Analog Center of Excellence (TxACE)--was presented last month at the International Solid-State Circuits Conference (ISSCC). Serial links consume about 20 percent of microprocessor power and constitute about 7 percent of overall energy consumption in a data center. These serial links are only sporadically used, such as when there is a request to access a webpage or a miss in the last level of cache. As part of the research, the Illinois team designed a 7-gigabit per second transceiver with the first reported on/off embedded clock architecture. The new transceiver achieved an order of magnitude lower serial link power-on compared to existing transceivers. The team estimates that data centers in North America can save $870 million annually using this approach, with the yearly serial link power savings at data centers worldwide by 2020 equaling Japan's yearly electricity consumption.

Graphene Light Bulb Expected to Last Longer, Be More Efficient, Save Money and Energy
A lightbulb with lower energy emissions, longer lifetime and lower manufacturing costs, and made with graphene -- said to be the first commercially viable consumer product using the super-strong form of carbon -- is poised to hit the market this year, thanks to a University of Manchester research and innovation partnership. The bulb's developers -- a Canadian-financed company called Graphene Lighting -- expect the dimmable bulb to use 10 percent less energy than conventional bulbs, last longer and be priced lower than some LEDs, at roughly $20 each. It was designed at the University of Manchester, where the revolutionary material was discovered. The University's National Graphene Institute was opened this month.

Study: Metals Used in High-Tech Products Face Future Supply Risks
In a new paper, a team of Yale researchers assesses the "criticality" of all 62 metals on the Periodic Table of Elements, providing key insights into which materials might become more difficult to find in the coming decades, which ones will exact the highest environmental costs -- and which ones simply cannot be replaced as components of vital technologies.

3-D printing gets a way to instantly recycle plastic waste into new 3-D 'ink'
Three students at the University of British Columbia -- Dennon Oosterman, Alex Kay and David Joyce -- have come up with a way to reduce the waste as well as the cost of 3-D printing. The three have designed an instant plastic recycling machine for home and small-business 3-D printers. The unique feature of this consumer-oriented extruder is that it has a built-in function to grind and pound plastic waste -- like pieces of the lids from coffee cups -- into small pellets. The machine, called a ProtoCycler, accepts ABS and PLA plastic waste, though each batch of waste for making into new "ink" filaments must come from the same type of plastic. The ProtoCycler can then extrude new plastic filaments from the pellets at a rate of 5 to 10 feet per minute. That's faster than traditional extruders. The ProtoCycler machine also uses less energy than typical plastic filament-producing equipment, so it is more efficient. Colors will be able to be added to the filaments.

Flood Brothers Disposal pioneers BioBin program to compost food waste
Chicago--In a continuing effort to improve waste recycling in our communities, a test program is under way at the Flood Brothers plant to recycle food waste in an innovative way. Food scraps and other organic material -- collected from restaurants, food service organizations and grocery stores -- are placed in Bio-Bins filled with earthworms. The worms eat the nutrient-rich fruit and vegetables, turning them into compost. This compost is known as vermicompost, which is valuable as a plant fertilizer. Source: Daily Herald, 3/17/15

IBM, Honeywell, CH2M Hill join White House on emissions cuts
The notion of confronting environmental risks embedded in complex global supply chains got a big endorsement last week; President Barack Obama made a pledge that the federal government will reduce greenhouse gas emissions by 40 percent within a decade, simultaneously wresting related pledges from 14 major federal suppliers.

4 reasons why the Supreme Court's mercury case is worth watching
This week, the Supreme Court will hear argument in Michigan v. EPA, an important environmental case challenging the EPA's Mercury and Air Toxics Standards. These vital regulations address the risks associated with emissions of hazardous air pollutants like mercury and arsenic from coal- and oil-fired power plants. Source: Grist, 3/23/15

Panasonic joins quest for greener cell towers
One tradeoff of the world's increasingly mobile mindset is the energy that cellular communications towers and wireless hotspots suck up to support all those transient connections. The dilemma is acute both in emerging markets, where diesel fuel often must be trucked to remote sites to keep them running, and in established economies where energy costs are spiraling out of control. A new solution from Panasonic Eco Solutions and technology partner PowerOasis could have appeal in both scenarios. The technology, called Green Tower, combines lithium-ion batteries with solar modules and management software to support sites with loads of 50 watts to 3 kilowatts. It can be used in both off-grid and on-grid configurations. The intent is to help telecommunications carriers save 10 percent to 20 percent on their energy infrastructure costs annually, according to Panasonic executives. Source: GreenBiz.com, 3/24/15

E-Waste Event Sponsored by GSA NCR Personal Property Management Division
GSA Personal Property Management Division National Capital Region is hosting an E-Waste Event on April 22, 2015. The purpose of this event is to give local area federal agencies an opportunity to dispose of their unneeded, inoperable electronic assets. This disposal event will be free of charge to those who participate and will ensure assets are disposed of in an environmentally friendly fashion. We will partner with a disposal vendor who has agreed to pay the GSA Surplus Sales program for accumulations of federal electronic assets. Participants will receive certification that their property was disposed of in accordance with EPA regulations. Source: GSA, 3/18/15
