Braskem, a brazilian petrochemical company, has developed the world's first certified Green Plastic, according to ASTM D6866-06 Standard.
Braskem's Green Plastic is made 100% from renewable sources and is thus a better susbtitute for plastics made from oil.
Although other bioplastics already exist, Braskem's differentiate itself from others in the process used to produce ethene, which is made from
dehydrating the sugar-cane ethanol. That's how Braskem produces what it calls Green Ethene, and that's the main secret to a 100% renewable Green
That Green Ethene can be used to produce any kind of polyethylene(PE), which means any kind of plastic can be substituted by Braskem's Green
The chain of production of the green Ethen allows for a bigger reduction of the carbon dyoxide in the atmosphere. For every 1kg of green Polyethylene,
2.5kg of CO2 is captured.
Braskem's Green Plastic is also highly versatile and can be used in any industries without the need to investment in adjustments or modifications.
On top of that, it has a highly competitive price.
Plans for 2010:
Braskem just signed a contract with Brazil's biggest sugar-cane ethanol producer, Cosan, to buy 175,000,000 L of ethanol in the next 5 years. The
contract is estimated in USD 500,000,000.
Braskem is expanding its plant to allow the production of 200,000 tons of Green Plastic, of which 25% is already going to the asian market.
One of Braskem's main costumers in Asia is one of Japan's biggest cosmetics company, Shiseido.
About the ASTM D6866:
ASTM D6866 is the method approved by the U.S. Department of Agriculture for determining the renewable/biobased content of natural range materials like
ethanol additives, biodiesel additives, and other biobased products.
Borrowing on the principles of radiocarbon dating, ASTM D6866 is able to determine the renewable carbon content of almost any type of solid, liquid,
or gaseous products. The method provides a percentage determination of fossil carbon content versus renewable or biomass carbon content of a product
or fuel blend.
ASTM D6866 is used extensively to certify the biobased content of bioplastics.
The downside of Green Plastic:
Although Braskem's Green Plastic is made from 100% renewable sources, that doesn't mean it is biodegradable. The production of the Green Plastic is
more environmentally friendly, but it is only half of the solution. Hopefully, with more investments and good intentions to go in the right direction,
one day we will find the perfect solution.
In the mean time, it's best to have a Green Plastic than the oil based plastic.
