Notes On Dow’s Brazilian Biopolymers Project

As you may have heard, Mitsui and Co. has signed on to an integrated joint venture with Dow to make biopolymers in Brazil. Here are a few observations: 1) What Dow is talking about here is the project it has been planning since 2007 to build a 350,000-metric-ton-per-year linear low-density polyethylene plant that is integrated all the way back to the sugarcane field. Dow originally partnered with Brazilian sugar cane processor Crystalsev, but that company pulled out when its parent, Santelisa was purchased by Louis Dreyfus around the end of 2009. However, this remained an active project within Dow, which proceeded for a couple of years on its own. 2) Dow isn’t coming out and saying it is building a 350,000 MTPY LLDPE plant. The exact size depends on engineering, though Luis Cirihal, Dow’s director of renewable alternatives and business development for Latin America (Dow likes long titles), assures me that it would be “world-scale”, which means about 350,000 metric tons. 3) Dow really won’t come out and say it is an LLDPE plant, exactly, either. The company rather euphemistically is referring to it as a “differentiated polymers” or a “performance polymers” plant. This is a new habit for the company. What I think the company means is that the plant uses its solution process, which is a platform for not only LLDPE, but also for plastomers and elastomers and the like. Dow’s terminology is meant to exclude the old Union Carbide gas-phase Unipol process. 4) A little more on this. Dow has indicated in the past that it is seeking to divest polypropylene and high-density polyethylene. Obviously a HDPE plant can swing to LLDPE. So what I think that Dow means is that it intends to keep the solution process and divest the Unipol process assets. This might not be an absolute. In any case, I have heard from a couple of people who would know about such things that Dow has only been actively marketing the polypropylene business anyway. This would make sense because shale is likely making HDPE a profitable business at the moment. 5) Dow is growing 17,000 hectares of sugarcane in Minas Gerais, Brazil. (This marks the first time a company from Michigan has EVER established a plantation in Brazil to find an alternative source of raw materials for a polymer. Maybe it doesn’t.) 6) Back to the Brazilian project. Later this year, the JV will begin construction of a 240-million-liter-per-year ethanol plant that will be finished in Q2 2013. 7) Financial details are sketchy. Mitsui says it invested $200 million in the JV thus far. I take it Dow has invested that much, too. And I suppose that amount would include the sugarcane growing and processing as well as the ethanol plant. I would think that it doesn’t include the ethanol dehydration plant (to make the ethylene), cogeneration, and the polymer plant. I reckon this total investment, which Dow is calling its largest ever in Brazil, could reach about $1 billion at the end of the day. Eight) According to my calculations, the amount of ethanol planned would only yield about 150,000 metric tons of ethylene. And thus it will only integrate about half of the plant. 9) Braskem already makes about 200,000 metric tons of HDPE per year based on ethanol. Dow says its plant will have cost advantages because it will be integrated. It is true that Dow's plant will be the only integrated plant when it is completed, but it might not be true for long. Braskem is studying a 400,000-metric-ton grassroots plant that would be integrated. 10) Braskem has a monopoly on ethylene production in Brazil. I asked Cirihal if getting around that monopoly was a rationale for the plant. “Absolutely,” he said. “It will serve as a mechanism of enabling the participation in an attracting, growing market in Brazil.”

  1. What exactly does Dow mean when they say their plant will be integrated? Integrated with downstream processing capacity into polymers?

  2. The chemicals will be integrated into sugar cane and ethanol. Braskem, thus far, buys ethanol on the merchant market.
