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.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
