2. 8,394,900 
 Profitable method for carbon capture and storage 

There is a growing consensus among climate scientists that the increasing concentration of heat trapping carbon dioxide (CO2) in the atmosphere--mainly from combustion of fossil fuels--is contributing to global warming. Consequences of global warming include melting of polar ice caps and rising sea levels, threatening arctic ecosystems and endangering coastal communities.  Climate scientists argue that during most of human history--up to the industrial revolution--the air held no more than 275 ppm CO2. The atmospheric CO2 concentration in 2009 was 385 ppm and rising. To slow down global warming, CO2from high fossil fuel emission sources such as coal-fired power plants, needs to be captured and "returned" to the ground--essentially reversing the fossil fuel mining, processing, and combustion process.

Abhari of Syntroleum Corporation, Oklahoma, developed a method for sequestering carbon dioxide.  Biomass is converted into paraffinic hydrocarbons.  The paraffinic hydrocarbons are steam cracked into olefins and polymerized into non-biodegradable polyolefins.  These plastics are 86% carbon by weight, non-biodegradable, and a major component of the world's landfills.  Each ton of carbon in the plastic would represent 3.67 tons CO2 removed from the atmosphere, stored within useful products, and ultimately sequestered in commercial landfills. Furthermore, the present method of carbon capture and storage is inherently market friendly and builds on existing manufacturing infrastructure.

1. 8,394,874 
Method and aqueous adhesive composition for the production of panels made from vegetable matter 

Graux and Mentink of Roquette Freres, France, developed an adhesive  including  vegetable starch the amylose content of which is between 30 and 60%.  This adhesive is used forming lignocelluloses panel by hot pressing.  The emissions of formaldehyde vapor are minimized as low as possible during processing and later use.  .
