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.

Ervin, I've been thinking the same thing myself. Left to their own devices, most companies will pay a minimal penalty at most to go green. If government mandate don't force the situation (as they now are in automotive) struggling companies simply won't do it.
I think it's kind of a no brainer that people will ask for greener when there's no cost involved. I think the challenge is to get the cost as low as possible so that consumers will actually decide to pay a little extra for green.
Often the government ends up jumping in to "encourage" the developement of green technology by giving cost incentives. I'm not a big fan of government involvement in subsidizing things. I do have to give them credit because I do like the idea of promoting green technologies.
I agree, Ann. I've changed a lot of my habits over the years as well. It's not difficult, just a matter of getting into a new habit. I'm able to recycle most of the waste in my household. A lot of what can be recycled can go into the compost. I'm down to taking the non-recycled materials out to the street about once a month.
Beth, I have also changed a lot of habits over the years, starting in the 1970s, such as recycling and water conservation. The latter has been relatively easy to do since I live in a drought-prone state and rationing has sometimes been mandated. More recently, I've changed what I buy, as better products have been available, especially recycled paper products that don't cost much more, and I also buy as little plastic as possible. For example, there are lots of bamboo alternatives to wood and plastic now. I also stopped buying commercial household cleaners except for Bon Ami, and mostly use baking soda and vinegar. It takes a little more elbow grease, but it's way cheaper and easier on the environment.
Chuck, I'm with you on the recycled plastic bridge materials. I still find them mind-boggling, so much so that I've told friends and acquaintances about it and they're amazed, too. This whole subject of green materials is as much fun to discover and report as news was in the whiz-bang days of Silicon Valley.
I would have to say that Cost will be the big driver. Currently the reason so many companies are using green materials is due to the hype about saving the planet. As this mentality dies out then so will the gains from using green materials (mostly marketing). Then the only way for this to be viable would be at no cost penalty.
I agree, Chuck. I think with all of the research being done and based on the recent reports Ann has written on biomimickry, with companies taking a page from Mother Nature to enhance the structural integrity and mechanical properties of their biomaterials projects, we're only at the beginning of all the progress to be made.
As long as the materials used is transparent to the customer, I am sure that most consumers will continue to back products that use green materials. With the backing specially among younger people, this emphasis is here to stay and will only continue to grow. Great report, Ann
For me, the most amazing of the green material application is still the load-bearing bridge members in Scotland. As soon as these materials get the mechanical properties that are needed, and there 's little or no cost penalty, use by engineers will really take off.
I think given the choice and without having to pay more, consumers will demand more environmentally friendly materials. I know I've started in small ways, buying recycled paper products and greener household cleaners. We recently had to have some insulation work done and specifically sought out a green resource. If the greener materials are readily accessible, look somewhat "normal," and perform in the way we as consumers expect them to perform, why not seek out something that's more earth friendly?
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.
