Quantifying the impact of materials on the environment






This website has an interesting overview of sustainability from a materials perspective, including the beginnings of a method for calculating the "Impact" of a material.


Their project, called Okala, http://www.idsa.org/whatsnew/sections/ecosection/okala.html is currently updating its list of calculated “impact” values for hundreds of materials and processes. For example, one assigns a value of 140 to a product if the material used is aluminum, while switching to the use of ABS plastic (which takes less energy to process in the raw form) brings the impact down to 47.

It looks like frozen smoke. And it's the lightest solid material on the planet. Aerogel is perfect for a variety of insulation applications including apparel, daylighting, oil and gas and LNG and cryogenic systems. It can also absorb oil and create a matte finish for coatings. Lawrence Livermore National Laboratory scientist Alex Gash shows us some remarkable properties of this truly unique substance.
