MIDLAND, Mich. (March 27, 2010) -- Dow Chemical, the world's leading plastics and chemicals company, will conduct a one-day preliminary test to determine whether plastic waste can be used as fuel in its own production. .
The test is scheduled to take place at the Dow headquarters plant in Midland, Michigan, at the end of July. The Midland plant is Dow's second largest manufacturing facility in the United States after the Freeport plant in Texas.
Jeff Wooster, Dow's director of sustainable plastics development, said in a July 21 telephone interview that the plastic waste of various shapes, sizes, and resin types will be burned during testing, and its energy will be recycled.
The waste used in the trial was provided by Dow employees, customers, and partners. Wooster said that most of the waste will be polyethylene and polypropylene, while common recyclables—such as PET, high-density PE bottles, and PE stretched films—will not be used in tests.
Wooster explained: “Every time we talk to our customers about energy recovery or chemical conversion, they want to be able to confirm it with their own eyes. The trial is just to show them further, and it is feasible and effective.â€
The wastes used in the tests do not need to be separately classified according to the resin category. Dow will use its waste directly as a fuel through its special process. This is different from the traditional pyrolysis method that uses plastic waste after it is heated and then processed into a chemical liquid or fuel. Wooster added that Dow is also working with technology partners to evaluate external waste conversion processes.
Dow researchers will measure the amount of energy generated by the plastic waste used in the experiment to see how much less gas Dow can use. Wooster said that if the trial is successful, the next step will be to expand the scale of implementation of this process.
The conversion of plastic waste into energy is not uncommon in many parts of the world, but for a variety of reasons, this practice has not been popularized in the United States.
When talking about this gap, Wooster said: "It was originally related to government policies and economic drivers. For example, in Japan, because of the small size of the country, there is basically no landfill, so the Japanese consciously recycle everything and use it in Europe. In countries such as Germany and Denmark in the north, there are fewer landfills there than in the United States."
Dow's approach is significant because Dow's plastics-related business accounted for approximately 40% of total sales of $46.6 billion in 2009. Among them, base plastics—including PE and PP—are Dow's largest single business areas, accounting for approximately 21% of its 2009 sales.
