Less emission from hybrid plastic

California-based bioplastic manufacturer Cereplast said the use of its Biopropylene hybrid resin (which can replace up to 50% petroleum-based plastic content) emits 42% less greenhouse gas emission compared to the use of regular polypropylene.

In a study by a professor from Michigan State University, he found that approximately 1.82 kilograms of carbon dioxide are produced for each kilogram of Cereplast’ Biopropylene used, compared to 3.14 kilograms of carbon dioxide emitted for the same amount of polypropylene.

“This is a very significant reduction in carbon dioxide emissions, especially when considering that worldwide market for polypropylene is about 45 billion kilograms, or approximately 100 billion pounds,”said Frederic Scheer, Cereplast’s Chairman and CEO.

Cereplast said its Biopropylene uses traditional polypropylene and up to 50% starch content.The plastic hybrid has been tested by more than 90 major corporations, said Scheer, with particular attention from companies in the automotive, consumer products and cosmetics industries.

    If the LCA holds up, this is a significant reduction of CO2.
    Going through the math, the reduction is ~90.7 million metric tonnes of CO2. In comparison, world-wide use of CO2 to make chemicals is around 115 million metric tonnes.

    Continuing the PLA discussion here, is this “bio-inside” composite recyclable with petroleum-produced PP?

    This is a good question for Cereplast although I’m guessing here that since it still has the traditional polypropylene component (unlike the pure PLA-based plastic) its recycle compatibility with pure PP plastic might be better. It might also depends on the weight content of the bioresin in the overall hybrid pp product.

    Could I have the name of the professor (from Michigan State University) who carried out the study over PP production and its environmental impact please?

    I am trying to compare CO2 emissions for one ton of both concrete and PP.

    I would like to see which one is the less energy-consuming.

    Thank you very much

    And there are others source which are rather different:

    have a look:

    1)1t of PP produced = 1,4t of CO2

    2)1t of PP produced = 3,7t of CO2

    Hi Martin,
    I believe his name is Professor Ramani Narayan. Here is a profile of him from Forbes.com. Hope this helps.
