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 FDA has just released draft guidelines for using 3D printing in the design, development, and manufacture of regulated medical products. Although the recommendations are non-binding, they do set some much-needed parameters.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
HP has launched its long-heralded Multi Jet Fusion 3D printing technology for commercial-scale end-production, plus an ecosystem to go with it. The package could change the entire industrial market for making end-products with additive manufacturing. At the very least, it will be game-changing.
