Found on the Web: "BioBasics" by the National Research Council Canada
 

We ran across a very interesting website from the National Research Council (Canada).  The site is titled BioBasics, and in it the NRCC has put together an excellent introduction to the overall topic of plastic biomaterials.  This site covers definitions of terms ("What are Biopolymers and Bioplastics?") as well as presenting an overview of the technology involving biomaterials themselves.  

The site offers the following menu to speed you to a topic of interest. 

When you reach that topic, we found the information is interesting and useful, such as the following excerpt:

  
The Science – How are Biopolymers and Bioplastics Made?....There are two methods being researched and used to produce plastics from plants. The first uses fermentation, and the second relies on the plant to become the factory for plastic production. These two methods are outlined below."

The Stratek Tek-MixTM Process Provides Lower Temperatures and Lower Pressures
Ideal for Biomaterial Processing

In the field of biomaterials, survivability is enhanced when materials are processed at lower temperatures and lower pressures.  These requirements are key features of Stratek’s Tek-MixTM mixing and blending technology.   For more information on the benefits of the Tek-MixTM process , click here.     For more on "Bio-Plastics" we recommend an article in the July Issue of Plastics Technology Magazine titled "Additives Are Needed for Toughness, Heat Resistance & Processability".

U.S. Demand for Biodegradable Plastic To Reach 720 Million lbs in 2012

 
August 29, 2008 - The Society of Plastics Engineers (SPE) - Tech Focus Website (contact direct)  --   Demand for biodegradable plastic in the U.S. is projected to rise more than 15%/yr to 720 million lbs in 2012, valued at $845 million. Although representing less than 0.5% of all thermoplastic-resin demand in 2007, biodegradable plastic will have substantial growth opportunities. Escalating crude-oil prices have made biodegradable plastics, which are sourced from renewable resources, more cost-competitive with petroleum-based conventional resin. However, continued price declines are necessary for demand for biodegradables to grow, and among the threats to further declines in prices are rapidly rising prices for corn. These and other trends are presented in Biodegradable Plastic, a new study from The Freedonia Group, Inc.

"US demand for biodegradable plastic will grow 15.5 percent annually through 2012. Gains will be driven by escalating costs for petroleum-based resins and growing initiatives that favor renewable resources. Polyester-based and polylactic acid resins will grow the fastest, while starch-based types remain the largest segment." -  The Freedonia Group website

Plastics remained a bright spot for U.S. trade in 2008 

By Tony Deligio
Published: October 21st, 2009

Despite a decline of 23% in the final quarter of the year, U.S. plastic exports increased by 6.7% in 2008 and eclipsed $50 billion for the first time ever, according to the latest international trade statistics for the plastics industry, which are summarized in a new report from the Society of the Plastics Industry (SPI; Washington, DC).

Exports during the fourth quarter of 2008 were off 23% from the prior quarter and 12% from the same quarter in 2007, but for the year, they exceeded $51 billion and accounted for approximately 4.4% of all U.S. exports. An overall trade surplus in plastics was not only maintained but expanded, as imports increased, but by only 3.0%, to just under $39 billion. The overall plastics trade surplus grew by nearly 20% from $10.9 billion in 2007 to $13.0 billion in 2008. Much of that surplus resulted from $18.4 billion in resins and raw material exports.
