I would think that in terms of flammability, the bioplastic would be more environmentally friendly over traditional automotive polymers.

Not exactly, but we have our own manufacturing concerns where we deal in different grades of plastic.

William, materials used in passenger cars, or in any vehicle used by citizens/consumers, are strictly regulated. I'd be very surprised if these hadn't been already tested for flammability. Test procedures these days can be very sophisticate and thorough.

Nadine, thanks for that definition and info. Bioplastics makers have usually worked hard to make sure their products *don't* smell like the feedstocks, for example, in the case of algae-based bioplastics. Most of them don't come from particularly good-smelling sources, or they come from relatively neutral-smelling ones. I doubt if ambient scenting has entered manufacturers' radar screens yet. Most of the effort to date has been getting processes scaled and materials up to par.

Ann, My concern about fire resistance is that this is a new material without a lot of history, so how it performs is not well known. And about the biodiesel fuel attacking the plastic, the concept of "like disolves like" is hard to ignore. It may indeed not be a problem, but that will depend on the similarity of the molecular structures. Sometimes things don't work exactly the way folks thought that they would. Now we do simulations, previously we did prototypes.

Ambient scenting is sometimes called scent marketing.  We're all very familiar with it.  When a store "smells like Christmas" or suddenly the smell of fresh baked cookies wafts through a mall making us seek out sweets, we're reacting to scent marketing.

New car smell is so popular that it's part of the vernacular.  Ambient scenting is used in consumer products in smaller ways, i.e. scratch and sniff jeans for kids. 

Personally, I'd tie the scent to the component that the bio-plastic is derived from if it's appealing.  Other choices could be to ink it to the colour.  Red=strawberries, brown=chocolate, cream=jasmine, green=grass or apples, etc.

Nadine, that sounds intriguing. Can you tell us what you mean by ambient scenting? Any specific scents?

William, I think skepticism is good. But plastics that are processed at high temperatures only melt at high temperatures. Fabrics already in use in many cars, no matter what they are made of, start burning at lower temperatures. And there's no particular reason to think a biodiesel spill will affect plastic car parts and worse than a perto-based diesel spill would. So I'm not sure what your concern is about these materials vs others already in use.

far911, I wondered that because you posted some promotional marketing text from UPM's press releases.

What make you think that.

Latest Analysis
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
If you’ve noticed the recent news about electric cars and batteries, then it’s easy to wonder about the continuing wisdom behind public subsidies for EVs.
