Recent developments in biopolymers

- Sep 27, 2009

Technical Paper - Society has been reaping the benefits of industrial polymers for a long time. Polymers have entered every market in a very influential manner, from the packaging industry to the construction business. The very properties that made polymers commercially viable are posing great environmental problems for our future generations. Also, the starting material for most of the commercial polymers is...

Ethanol to Ehylene - Nov 10, 2009
posted by John Dorgan at Chemical Engineering
We are making more than 10 billion gallons per year of ethanol in the USA. The federal mandate is for this to grow to more than 20% of the fuel supply over the next decade. We (the USA) burn 80 million barrels of oil PER DAY. So we'll soon be using 16 million barrels per day of renewable carbon for fuels.

Compared to these volumes, plastics is small. So my perspective is we can make bioplastics if we want to - there's plenty of renewable carbon available.

The issue, as always, is costs. The Brazillians are using old technology to take ethanol to ethylene and then making "green polyethylene." they can do this because ethanol costs $0.50 to make in Brazil. There's no shortage of synthetic routes to bioplastics with exactly the same chemical structure as the materials we already know and use.

As we move to biofuels to alleviate global warming and we switch to hybrids and then plug in hybrids, and perhaps ultimately electric cars petroleum will be used for airplanes, heavy trucks, and trains. It will also still be available for plastics because this is a "value added" proposition.

Let me conclude by stressing economics. Biomass is available for $26/dry ton. If you are a clever chemist/biochemist/chemical engineer then the world should be your oyster in a marketplace of $100/bbl oil!


polymer availability - Nov 02, 2009

The question is not about the availability of raw material for biopolymers. The most important challenge for plastic industry is to have available industrial facilities to process starch or other material to produce valid materials.
The global amount of starch is enough to cover the world demand. Then, industry should put efforts on scale up process to substitute comodities step by step.

BE CAREFUL, about BIOPOLYMERS - Sep 30, 2009
posted by GOURDON Bernard at E.C.T.I.
I am sceptic, because the volume of raw materials
to produce BIOPOLYMERS, is not enough, compare to the actual petrochemical source.
I agree that they can develop good properties, OK.
May be some small applications could be used.
But actually the world wide plastics capacity is around 220000.KT and we foresee in 2015 around 370000. KT.
