Green, sustainable materials -- some made out of shrimp shells, silk, and plant trash -- are being used for consumer packaging, shipping, and plastic bag replacements.
In fact, those are the largest applications for bioplastics, which are usually created in a process chain from ethanol to polymer that closely parallels the process for creating their petrochemical equivalents. Today durable-grade bioplastics are blended with petro-based plastics and incorporated into PCs. Engineering-grade bioplastics are being used in extreme, under-hood automotive applications.

Thanks, Beth. I agree: Except for the mushroom packaging, the green materials are mostly transparent to the user. Maybe that camouflage-like effect is one reason why so many of us don't realize that they're already here in so many different products we use every day.
I think there are two reasons green materials and approaches are taking off. Alex is right: the cost differential--in the sense of price of materials--is making these alternatives a no-brainer. But my research showed that the price differential swings back and forth between plus and minus depending on the ups and downs of the price of oil. The second major reason is consumer demand, which has been a longer-term factor.
What this slideshow brings to light is the fact that "green" is not a technology per se. Rather, it's a way of looking at design, from prototyping through to recycling, to figure out the most environmentally friendly way of doing things. However, as I've said before, the reason green is taking off is simply because now, with the rising price of oil, it's finally cost effective.
Very cool presentation, Ann. Really gives you a sense of the varied mix of products and packaging that is now able to take advantage of these green materials. It also shows that going green from a materials standpoint doesn't have to dramatically alter the look or feel of the product--it's almost transparent from a visual perspective, which could be a benefit for companies concerned about dramatically altering their goods.
The grab bag of plastic and rubber materials featured in this new product slideshow are aimed at lighting applications or automotive uses. The rest are for a wide variety of industries, including aerospace, oil & gas, RF and radar, automotive, building materials, and more.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
