In addition to winning over regulators and other key constituents, some green manufacturers are even cutting costs through their environmental initiatives, according to Mechanical Engineering magazine, the flagship publication of ASME.
In the January 2009 edition, the magazine profiles the environmental programs of Fuji Heavy Industries Ltd., IBM Corp., and carpet maker Bentley Prince Street Inc., among other firms. These manufacturers, according to Mechanical Engineering, have realized measurable efficiencies and cost savings through recycling, waste reduction, and energy conservation and reuse.
“Sustainable practices focus on reducing inputs per unit of output,” says Mechanical Engineering. “The difference between inputs and outputs is waste, and if a manufacturer can reduce waste, it can save money.”
Green manufacturers reconfigure processes, use environmentally benign substances in products, re-engineer products for easy disassembly, and incorporate other innovations in the quest to meet environmental goals.
For example, auto maker Subaru returns used metal packaging to parts suppliers so that the material can be used for other shipments. IBM takes in 40,000 pieces of pre-owned electronic equipment each week to recover silicon wafers and various metals, selling the materials on the open market as part of a $2 billion recycling business.
ASME in early 2008 convened the Global Summit on the Future of Mechanical Engineering, in which experts in the field indicated that engineers must take the lead in developing solutions that foster a cleaner, healthier, safer and sustainable world. One avenue to meeting that challenge is to focus on process.
“The whole idea behind resource utilization is to optimize processes,” says the January 2009 Mechanical Engineering. “That’s a skill engineers have.” To access the publication online, visit www.memagazine.org.
Founded in 1880 as the American Society of Mechanical Engineers, ASME is a not-for-profit professional organization promoting the art, science and practice of mechanical and multidisciplinary engineering and allied sciences. ASME develops codes and standards that enhance public safety, and provides lifelong learning and technical exchange opportunities benefiting the global engineering and technology community.

3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
