NO RATINGS

jimiller, I'm with you on that thought. The Europeans are way ahead of us in several green tech departments, and much of the related research has been funded by governments, in partnership with commercial entities and universities.

And in the case of something that will benefit all of us in the long run, occasionally the government needs to step in and provide the initial motivation to begin looking at a technology.  Green in this case.  But as compaies embrace the idea and continue to develop the technology, within a few years, hopefully, the technology will in fact be a more efficient way to make profits in a way that doesn't hurt the environment.

Rob, we are ahead on recycling out here, as well as on energy savings via methods like turning down the thermostat and going solar. We should be, but probably aren't, on water conservation, considering that most of the state is considered part of the dry Great Basin geographic area.

That's interesting that recycling has made a big enough difference that the waste folks have noted the change. It's picking up here, but it still looks like only about a third of my neighbors are putting much out on the street. You folks in California are way ahead on this.

I ask because a couple years ago our garbage company gave a lower tier price option, not for fewer garbage pickups, but smaller garbage containers, since so many people were recycling so much that the regular can size was too big. Of course, they go the other way--you can pay an extra fee for an extra pickup--but not down. I wish they would also size down price according to pickup frequency.

I actually don't know, Ann. Garbage pickup charges end up on the water bill, and I've never tried to read those things. Good question though. I think I'll take a look.

Rob, that sounds like my garbage company's schedule. My question is, can you pay a lower fee for fewer pickups than once a week? For example, if you only set out garbage twice a month for pickup instead of every week, do they have a lower price tier for that?

Well, I'm on a neighborhood street. The trash just come by once a week (two different trucks) for both at-the-curb recycling pickup as well as the trash for the landfill. I have recycling every week, even if I don't have landfill trash.

The willingness of consumers to pay a bit more for at least some green alternatives is increasing, while the price differentials come down. As I've pointed out several places, the Freedonia Group analyst I interviewed for an upcoming March feature feature made it clear that, at least for bioplastics, consumer demand for sustainable solutions is what's driving innovation. It's consumers who are willing to pay a price premium for ecological plastic bag replacements or EVs, for instance, not aerospace engineers who care if their aircraft components are made of green materials. So lumping everything together in a single discussion is somewhat misleading.

If I composted, we'd probably have our household waste down as far as yours, Rob. My excuse is living in the redwoods--no vegetable gardens here. The question is, will your garbage company pick up only once a month and give you a lower rate? Ours doesn't. I bet none of them do. They need to get with the program and start offering another rate structure level for reduced waste households like yours.

As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
3D printing, 4D printing, and various types of additive manufacturing (AM) will get even bigger in 2015. We're not talking about consumer use, which gets most of the attention, but processes and technologies that will affect how design engineers design products and how manufacturing engineers make them. For now, the biggest industries are still aerospace and medical, while automotive and architecture continue to grow.
More and more -- that's what we'll see from plastics and composites in 2015, more types of plastics and more ways they can be used. Two of the fastest-growing uses will be automotive parts, plus medical implants and devices. New types of plastics will include biodegradable materials, plastics that can be easily recycled, and some that do both.
