Plastic from…Bacteria

No, this isn’t fringe science.  This is real and is happening now, and it is the business of Genomatica, a chemical company based in San Diego, focusing on the bio manufacturing of sustainable chemicals.  In a process similar to biofuel creation, through the fermentation and manipulation of E. coli bacteria (along with sugar and water), Genomatica has developed a petroleum-free incarnation of butanediol (BDO), a versatile chemical compound common to a range of plastic products.  Noteworthy, is the company’s intent to utilize particular kinds of sugars which do not threaten the scarcity of foodstock-based sugars on world markets.  The company chose to initially focus on BDO due to the dramatically increasing cost and energy-intensive nature of its fossil-fuel based production, and because it is such a ubiquitous product within the world of plastics.

If the company can indeed develop a cost-competitive plastic from their more environmentally friendly approach, they will have proven the viability of potentially large-scale non petroleum-based manufacturing solutions.  According to Genomatica’s own brief on how the company views sustainability, “… government, academia and industry should strive to maximize resource efficiency through activities such as energy and non-renewable resource conservation, risk minimization, pollution prevention, minimization of waste at all stages of a product life-cycle, and the development of products that are durable and can be reused and recycled.”  It’s hard to beat that, so we should all keep our eyes on the work of Genomatica, for we might be seeing some great things emerge from this company in years to come.

Pet Doo-doo Dilemmea

Are you one of the millions of pet owners who experience second degree duty grief every day? Every time you take your dog for a walk, do you take along a doo-doo bag?  Every time you change the kitty litter, do you scoop it into a plastic bag to have a stink free trash? For all of you pet owners out there, your pets can now do their business and you can get off guilt free. (Disclaimer: this does not solve the actual litter toxicity problem but does although solve excrament disposal issues.)

New to the market this summer, Perf Go Green is introducing a full line of 100% biodegradable kitty litter bags and waste bags of all sizes.  When less than 2% of plastic bags get recycled, it is easy to see the responsible next step. Standard plastic bags take anywhere from 100-500 years to break down, while biodegradable bags take anywhere from 12-24 months to break down leaving far less mass in landfills annually.

Manufactured by Spectrum Plastics, these bags are composed of recycled plastic, OXO-biodegradable additives, and are designed with a perforated film to aid in the decomposition process. Keep your eye peeled and your conscience out of the guilt weeds.

BASF Adds a “Story” Section to Their Website

In the spirit of open communications with the public about their green projects, BASF has launched a section on their site devoted to promoting their green initiatives that have successfully had positive impacts on the environment. One material they’ve released recently is called Ecoflex, a plastic they say is completely biodegradable and compostable. Targeted as a replacement material in the production of trash bags and disposable packaging, it’s designed to decompose (in compost) within a few weeks. In soil, BASF claims it will leave no residues. Ecoflex is engineered to work just like Low Density Polyethylene, allowing it to be made into films, bags or coatings. This bio-based plastic does not require drying and remains stable for one year on the shelf or being warehoused.

BASF is also working on initiatives such as PremAir, a catalyst product for the commercial market that destroys harmful, ground-level ozone (different from the ozone that we’re used to hearing about). A main component of smog (smoke and fog), ground-level ozone causes eye and nose irritation while weakening the immune system, increasing chances of illness. It’s been found by some studies that hospital visits and fatalities caused by respiratory complications are increased when ground-level ozone amounts are higher than average. When BASF’s PremAir coating is applied to heat-exchange surfaces, such as traditional car radiators for example, the catalyst coating manages to reduce ground-level ozone in the air, converting the ozone molecules into oxygen molecules instantly upon surface contact.

Bio-based Plastics That Can Survive Freezing Temperatures

CP-INJ-13 is the first ever first-ever freeze-tolerant bio-based resin. This material is an extension of the existing biodegradable, compostable plastics in the Cereplast line. A substitute for petroleum-based plastic, their alternatives are starch-based, made from corn, wheat, tapioca and potato starches. To learn more about the new PLA (polylactic acid), click here…

Bioplastics Magazine

Bioplastics magazine is a relatively new publication dedicated to inform designers, and manufacturers about the latest technology available in sustainable plastics.

The magazine was launched in may 2006, and feature news and reports about all topics around bioplastics. Including precise reports on material properties.

First issues are available from the website.

Mirel Bioplastic by Metabolix

The public knows the basic about bioplastic. What is actually produced with such plastics ? As designers it’s good to know who to contact, when we actually need to develop a project with such product, i would like to present Mirel, produced by Metabolix a 15 years old company specialised in bio plastic research.

What is Mirel ?

A family of plastic based on corn sugar. Its biobased sustainable and biodegradable.

When we see (- Plastic debris piling up in Pacific - ) what happen to our tons of plastic it’s urgent to go for biodegradable.

What can be done with Mirel family ?

Mirel can be used in a wide variety of applications, from packaging, to cosmetic cases, from plastic bags to toothbrushes.

it’s support injection molding, extrusion coating and could be provided as sheet.

Mirel is well documented in ecolect database, have a look, register and share your knowledges with the community.

For more information on Mirel properties, check Metabolix presentation on their website.
