Ask the EcoGeek: Durable Bio-Plastics


Dear EcoGeek,
Have there been any developments in the pursuit of sustainable, cost-effective alternatives to plastics? I am aware of the recent gains in using corn starch to produce biodegradible plastics (chocolate candy trays, shopping bags, etc.), but what about durable goods such as toolboxes, exercise equipment, or any other product made from plastic that is designed to last.
Thanks for your time and www.pneumapaniagua.es expertise.
Jim

Hey Jim,
It does seem a bit silly that we wouldn't solve two problems at once here. I mean, as long as we're removing oil from the http://www.aagon.de/herbal-cialis process, why don't we move away from our foolish disposable-everything culture as well?

But this all becomes more clear if we ask a different question. Instead of “why aren't there durable bio-plastics?” we should first ask “what's wrong with durable petro-plastics?” Lets start by listing the reasons why oil sucks.
  1. We will eventually run out
  2. When we burn it, it creates CO2
  3. When we throw away petro-plastic, it pretty much never biodegrades and can harm wildlife
  4. Refining oil is energy intensive and produces toxic chemicals
  5. We often have to import it from places with unstable politics

Now, those are five really good reasons to wow it's great levitra buying stop burning oil. Taken together, I can't quite figure out why we're still burning the stuff. But when we talk about disposable plastics, the second problem, that of online propecia uk carbon dioxide, isn't a problem anymore, so only four problems remain. And when we list reasons for replacing durable products, the list gets even shorter.

We don't burn it, we don't throw it away, and even if we do, it would persist as much as petro-plastics. Plus, the demand for durable petro-plastics is considerably lower than the demand for fuel and disposable plastic. Because we're talking about fewer petrochemicals in total, all of the above problems are diminished. In fact, creating durable plastics is pretty much the most intelligent use of oil, as we gain permanent benefits from the items we produce and the environmental consequences are much less significant.

That being said, the world would probably be better off if we figured out ways to completely erase our need for oil. And some people have begun creating durable plastics from biological stock. There's no technical reason why we can't do it. But there are fewer economic and ecological reasons to replace durable plastics than disposable plastics.

this misses the point entirely

oil is simply sequestered carbon, as is biomass as are you and me. the issue is tramadol us pharmacies overnight management of that resource. using biological carbon is in the long run simply more immediately regenerative where as oil takes millenia to resequester. using petrochemicals in itself is not inherently bad, using them irresponsibly is. if you're going to build a long term item, end of life concerns need to canadian viagra be addressed, but many things can be repurposed or recycled. if we're lookign to plants as a panecea to replace our addiction to oil, we'll only be hooked on we like it cialis in uk laudanum instead of heroin. we need to reduce our consumption, and recycle that which we can not reuse (for whatever reason, food safety, medical materials, broken product, etc.)

As durable bio-polymers go, bamboo has a lot going for it.

Shellac is kind of old-school, and not all that strong, but it is durable in certain circumstances. Interestingly, it starts out as a thermoplastic, but becomes a thermoset resin if it isn't recycled after several years.

And let's not forget the king of http://visionwidget.com/generic-levitra-from-india durable bio-polymers: polyisoprene. Synthetic polyisoprene is sometimes cost-competitive with the stuff we get from rubber trees, but there's huge demand for natural latex, as well. When cross-linked into a hard rubber, it's quite durable: just try to break a well-made comb of this material, if you don't believe me.

Thermal depolymerization
written by Tilt, July 30, 2007
Processing waste with the thermal depolymerization process would allow for recycling of plastics, metals, water and www.breinweb.nl mineral materials. The output is described as a "light crude oil" type product, which presumably could then be remanufactured into plastics again. Or, of course, sequestered somewhere.
