Dow Chemical Company: История и развитие американского химического гиганта

American chemical company

The Dow Chemical Company is an American multinational corporation headquartered in Midland, Michigan, United States. The company was among the three largest chemical producers in the world in 2021. It is the operating subsidiary of Dow Inc., a publicly traded holding company incorporated under Delaware law. With a presence in around 160 countries, it employs about 36,000 people worldwide. as its sales are to other industries rather than directly to end use consumers. Dow is a member of the American Chemistry Council. In 2015, Dow and fellow chemical company DuPont agreed to a corporate reorganization involving the merger of Dow and DuPont followed by a separation into three different entities. The plan commenced in 2017, when Dow and DuPont merged to form DowDuPont, and was finalized in April 2019, when the materials science division was spun off from DowDuPont and took the name of the Dow Chemical Company.

Dow was founded in 1897 by chemist Herbert Henry Dow, who invented a new method of extracting the bromine that was trapped underground in brine at Midland, Michigan. The company originally sold only bleach and potassium bromide, achieving a bleach output of 72 tons a day in 1902. Early in the company's history, a group of British manufacturers tried to drive Dow out of the bleach business by cutting prices. Dow survived by also cutting its prices and, although losing about $90,000 in income, began to diversify its product line. In 1905, German bromide producers began dumping bromides at low cost in the U. S. in an effort to prevent Dow from expanding its sales of bromides in Europe. Instead of competing directly for market share with the German producers, Dow bought the cheap German made bromides and shipped them back to Europe. This undercut his German competitors. Even in its early history, Dow set a tradition of rapidly diversifying its product line. Within twenty years, Dow had become a major producer of agricultural chemicals, elemental chlorine, phenol and other dyestuffs, and magnesium metal. During World War I, Dow supplied many war materials that the United States had previously imported from Germany. Dow produced magnesium for incendiary flares, monochlorobenzene and phenol for explosives, and bromine for medicines and tear gas. By 1918, 90 percent of Dow's production was geared towards the war effort. At this time, Dow created the diamond logo that is still used by the company. After the war, Dow continued research in magnesium, and it developed refined automobile pistons that produced more speed and better fuel efficiency. The Dowmetal pistons were used heavily in racing vehicles, and the 1921 winner of the Indianapolis 500 used the Dowmetal pistons in his vehicle.

From 1940 to 1941, Dow built its first plant in Freeport, Texas, to produce magnesium extracted from seawater rather than underground brine. The Freeport plant is Dow's largest site, and the largest integrated chemical manufacturing site in the country. The site grew quickly – with power, chlorine, caustic soda and ethylene also soon in production. Growth of this business made Dow a strategic company during World War II, as magnesium became important to manufacture lightweight parts for aircraft. Based on 2002–2003 data, the Freeport plants produced 27 billion lbs of product – or 21% of Dow's global production. In 1942, Dow began its foreign expansion with the formation of Dow Chemical of Canada in Sarnia, Ontario, to produce styrene for use in styrene butadiene synthetic rubber. Also during the war, Dow and Corning began their joint venture, Dow Corning, to produce silicones for military and, later, civilian use. The Ethyl Dow Chemical Co. plant at Kure's Beach, NC, the only plant on the East Coast producing bromine from seawater, was attacked by a German U boat in 1942. In the post war era, Dow began expanding outside of North America, founding its first overseas subsidiary in Japan in 1952, and in several other nations soon thereafter. Based largely on its growing plastics business, Dow opened a consumer products division, beginning with Saran wrap in 1953. Based on its growing chemicals and plastics businesses, Dow's sales exceeded $1 billion in 1964 and $2 billion in 1971.

From 1951 to 1975, Dow managed the Rocky Flats Plant near Denver, Colorado. Rocky Flats was a nuclear weapons production facility that produced plutonium triggers for hydrogen bombs. Contamination from fires and radioactive waste leakage plagued the facility under Dow's management. In 1957 a fire burned plutonium dust in the facility and sent radioactive particles into the atmosphere. According to the Appellate Court, the owners of the 12,000 properties in the class action area had not proved that their properties were damaged or they had suffered bodily injury.

The United States military used napalm bombs during the Vietnam War until 1973. Dow was one of several manufacturers who began producing the napalm B compound under government contract from 1965. After experiencing protests and negative publicity, the other suppliers discontinued manufacturing the product, leaving Dow as the sole provider. The company said that it carefully considered its position, and decided, as a matter of principle, "its first obligation was to the government". Despite a boycott of its products by anti war groups and harassment of recruiters on some college campuses, Dow continued to manufacture napalm B until 1969. In 2012, Monsanto agreed to a $93 million settlement as a result of a case pursued by ex Monsanto employees and citizens in the city of Nitro, WV. In 1949, a chemical plant in Nitro experienced an explosion that damaged a tank containing 2,4,5 T, one of the composites that is used in the production of Agent Orange. The settlement of the case included $9 million for the cleanup of affected homes in the area, and $84 million to cover the medical monitoring and treatment of people affected by the explosion, as well as legal costs for the claimants. No care has been given for the in state damage done by the Headquarters in Midland, Michigan, and they refuse to give the evidence to the community.

A major manufacturer of silicone breast implants, Dow Corning (Dow Chemical's Joint Venture with Corning Inc.) was sued for personal damages caused by ruptured implants. On 6 October 2005, all such cases pending in the District Court against the company were dismissed. A number of large, independent reviews of the scientific literature, including the Institute of Medicine in the United States, have subsequently found that silicone breast implants do not cause breast cancers or any identifiable systemic disease.

The Bhopal disaster occurred at a pesticide plant owned by Union Carbide India Ltd., a subsidiary of Union Carbide, in 1984. A gas cloud containing methyl isocyanate and other chemicals spread to the neighborhoods near the plant where more than half a million people lived. The government of Madhya Pradesh confirmed 3,787 deaths related to the gas release. The leak caused 558,125 injuries, including 38,478 temporary partial injuries and approximately 3,900 severely and permanently disabling injuries. Union Carbide was sued by the Government of India and agreed to an out of court settlement of US$470 million in 1989. Dow Chemical acquired Union Carbide in 2001. Activists want Dow Chemical to clean up the site which is now controlled by the state of Madhya Pradesh.

Until the late 1970s, Dow produced DBCP (1,2 dibromo 3 chloropropane), a soil fumigant, and nematicide, sold under the names the Nemagon and Fumazone. Plantation workers who alleged that they became sterile or were stricken with other maladies subsequently sued both Dow and Dole Foods in Latin American courts. The cases were marred by extensive fraud, including the falsification of test results and the recruitment of plaintiffs who had never worked at Dole plantations. While Nicaraguan courts awarded the plaintiffs over $600 million in damages, they have been unable to collect any payment from the companies. A group of plaintiffs then sued in the United States, and, on 5 November 2007, a Los Angeles jury awarded them $3.2 million. Dole and Dow vowed to appeal the decision. On 23 April 2009 a Los Angeles judge threw out two cases against Dole and Dow due to fraud and extortion by lawyers in Nicaragua recruiting fraudulent plaintiffs to make claims against the company. The ruling casts doubt on $2 billion in judgments in similar lawsuits.

In February 2013 a federal court rejected two tax shelter transactions entered into by Dow that created approximately $1 billion in tax deductions between 1993 and 2003. The court wrote that the transactions were "schemes that were designed to exploit perceived weaknesses in the tax code and not designed for legitimate business reasons". The schemes were created by Goldman Sachs and the law firm of King & Spalding, and involved creating a partnership that Dow operated out of its European headquarters in Switzerland. Dow stated that it had paid all tax assessments with interest. The case was against the Internal Revenue Service seeking a refund of the taxes paid. The case was appealed to the 5th Circuit court, where Dow's claims were again rejected. Dow has petitioned for an en banc hearing by the 5th Circuit, arguing that the decision was contrary to established case law.

Dow Chemical was implicated in a price fixing scheme that inflated the cost of polyurethane for customers. The U. S. Justice Department closed an investigation in 2007, but a class action lawsuit won at a jury trial in 2013. Dow settled the suit in 2016 for $835 million.

In the early 1990s, Dow embarked on a major structural reorganization. The former reporting hierarchy was geographically based, with the regional president reporting directly to the overall company president and CEO. The new organization combines the same businesses from different sites, irrespective of which region they belong (i. e. the vice president for Polystyrene is now in charge of these plants all over the world).

At the beginning of August 1999, Dow agreed to purchase Union Carbide Corp. (UCC) for $9.3 billion in stock. At the time, the combined company was the second largest chemical company, behind DuPont. This led to protests from some stockholders, who feared that Dow did not disclose potential liabilities related to the Bhopal disaster. William S. Stavropoulos served as president and chief executive officer of Dow from 1995 to 2000, then again from 2002 to 2004. He relinquished his board seat on 1 April 2006, having been a director since 1990 and chairman since 2000. During his first tenure, he led the purchase of UCC, which proved controversial, as it was blamed for poor results under his successor as chief executive officer, Mike Parker. Parker was dismissed and Stavropoulos returned from retirement to lead Dow.

On 10 July 2008, Dow agreed to purchase all of the common equity interest of Rohm and Haas Co. for $15.4 billion, which equated to $78 per share. The buyout was financed with equity investments of $3 billion by Berkshire Hathaway Inc. and $1 billion by the Kuwait Investment Authority. The purpose of the deal was to move Dow Chemical further into specialty chemicals, which offer higher profit margins than the commodities market and are more difficult to enter for the competition. The purchase was criticized by many on Wall Street who believed Dow Chemical overpaid (about a 75 percent premium on the previous day's market capital) to acquire the company; however, the high bid was needed to ward off competing bids from BASF. The transaction to purchase the outstanding interest of Rohm and Haas was closed on 1 April 2009.

On 8 December 2008, Dow announced that due to the Financial crisis of 2007–2008, it would accelerate job cuts resulting from its reorganization. The announced plan included closing 20 facilities, temporarily idling 180 plants, and eliminating 5,000 full time jobs (about 11 percent of its work force) and 6,000 contractor positions.

Citing the global recession that began in the latter half of 2008, the Kuwaiti government scuttled the K Dow partnership on 28 December 2008. The collapse of the deal dealt a blow to Dow CEO Andrew Liveris' vision of restructuring the company to make it less cyclical. However, on 6 January 2009 Dow Chemical announced they were in talks with other parties who could be interested in a major joint venture with the company. Dow also announced they that it would be seeking to recover damages related to the failed joint venture from PIC. The deal was expected to be finalized in early 2009 and was to form one of the nation's largest specialty chemicals firms in the U. S. However, on 26 January 2009 the company informed Rohm and Haas that it would be unable to complete the transaction by the agreed upon deadline. Dow cited a deteriorated credit market and the collapse of the K Dow Petrochemical deal as reasons for failing to timely close the merger. Around the same time, CEO Andrew Liveris said a first time cut to the company's 97 year old dividend policy was not "off the table". On 12 February 2009, the company declared a quarterly dividend of $0.15/share, down from $0.42 the previous quarter. The cut represented the first time the company had diminished its investor payout in the dividend's 97 year history. The transaction to purchase the outstanding interest of Rohm and Haas closed on 1 April 2009. After negotiating the sale of preferred stock with Rohm and Hass' two largest stockholders and extending their one year bridge loan an additional year, the company purchased Rohm and Haas for $15 billion ($78 a share) on 9 March 2009.

On 12 April 2007, Dow dismissed two senior executives for "unauthorized discussions with third parties about the potential sale of the company". The two figures are executive vice president Romeo Kreinberg, and director and former CFO J. Pedro Reinhard. Dow claims they were secretly in contact with JPMorgan Chase; at the same time, a story surfaced in Britain's Sunday Express regarding a possible leveraged buyout of Dow. The two executives have since filed lawsuits claiming they were fired for being a threat to CEO Liveris, and that the allegations were concocted as a pretext. However, in June 2008 Dow Chemical and the litigants announced a settlement in which Kreinberg and Reinhard dropped their lawsuits and admitted taking part in discussions "which were not authorized by, nor disclosed to, Dow's board concerning a potential LBO" and acknowledged that it would have been appropriate to have informed the CEO and board of the talks.

In summer 2008, Dow sold its zoxamide business to Gowan Company. Included in the sale were the trademarks for a potato and grape fungicide called Gavel (fungicide). It is employed by potato growers to control early and late potato blight and is also registered in Canada for control of downy mildew in grapes, except in British Columbia.

In the fourth quarter of 2014, Dow announced new operating segments in response to its previously announced leadership changes. The company stated it would give further support to its end market orientation and increase its alignment to Dow's key value chains – ethylene and propylene.

Several plants on the Gulf Coast of the US have been in development since 2013, as part of Dow's transition away from naphtha. Dow estimates the facilities will employ about 3000 people, and 5000 people during construction. The plants will manufacture materials for several of its growing segments, including hygiene and medical, transportation, electrical and telecommunications, packaging, consumer durables and sports and leisure. Dow's new propane dehydrogenation (PDH) facility in Freeport, Texas, was expected to come online in 2015, with a first 750000 tonne per year unit, while other units would become available in the future. An ethylene production facility was expected to start up in the first half of 2017.

On 27 March 2015, Dow and Olin Corporation announced that the boards of directors of both companies unanimously approved a definitive agreement under which Dow will separate a significant portion of its chlorine business and merge that new entity with Olin in a transaction that will create an industry leader, with revenues approaching $7 billion. Olin, the new partnership, became the largest chlorine producer in the world.

On 11 December 2015, Dow announced that it would merge with DuPont, in an all stock deal. The combined company, which was known as DowDuPont, had an estimated value of $130 billion, was equally held by the shareholders of both companies, and maintained their respective headquarters in Michigan and Delaware. Shareholders of each company held 50% of the combined company. In the new entity, Dow Chemical chief executive officer Andrew N. Liveris became executive chairman and DuPont chief executive officer Edward D. Breen became chief executive officer. In January 2017, the merger was pushed back a second time pending regulatory approvals. The same day, Dow also announced that it had reached a deal to acquire Corning Incorporated's stake in their joint venture Dow Corning for $4.8 billion in cash and a roughly 40% stake in Hemlock Semiconductor Corporation. Also in 2019 Dow employees won an Adhesives and Sealants Council Innovation Award for "UV Curable Primer that Enables Hard to Bond INFUSE Olefin Block Copolymer Midsole Foams in High Performance Footwear".

Dow Chemical has begun to shed commodity chemical businesses, such as those making the basic ingredients for grocery bags and plastic pipes, because their profit margins only average 5–10%. Dow is, as of 2015, focusing its resources on specialty chemicals that earn profit margins of at least 20%.

Areas along Michigan's Tittabawassee River, which runs within yards of Dow's main plant in Midland, were found to contain elevated levels of the cancer causing chemical dioxin in November 2006. The dioxin was located in sediments two to ten feet below the surface of the river, and, according to The New York Times, "there is no indication that residents or workers in the area are directly exposed to the sites". However, people who often eat fish from the river had slightly elevated levels of dioxin in their blood. In November 2008, Dow Chemical along with the United States Environmental Protection Agency and Michigan Department of Environmental Quality agreed to establish a Superfund to address dioxin cleanup of the Tittabawassee River, Saginaw River and Saginaw Bay.

In December 2015, Dow Chemicals agreed to sell part of its global herbicide business, which had reported falling sales for nearly a year. A portfolio of weed killers known as dinitroanilines was sold to privately held Gowan Company, a family owned company located in Yuma, Arizona, which markets a variety of pesticides to the agricultural and horticultural industries. The global trademarks for Treflan (pesticide)®, which can be sprayed on field corn, cotton and some fruit and vegetables, were included in the sale, as well as a formulation and packaging facility in Fort Saskatchewan, Alberta, Canada.

In May 2020, Dow Chemical and many other areas in Midland County, Michigan were forced to evacuate due to high flooding which was caused by the breach of the Edenville and Sanford dams following two days of heavy rainfall in the area.

Dow is a large producer of plastics, including polystyrene, polyurethane, polyethylene, polypropylene, and synthetic rubber. It is also a major producer of ethylene oxide, various acrylates, surfactants, and cellulose resins. It produces agricultural chemicals including the pesticide Lorsban and consumer products including Styrofoam. Some Dow consumer products, including Saran wrap, Ziploc bags, and Scrubbing Bubbles were sold to S. C. Johnson & Son in 1997.

Performance plastics make up 25% of Dow's sales, with many products designed for the automotive and construction industries. The plastics include polyolefins such as polyethylene and polypropylene, as well as polystyrene used to produce Styrofoam insulating material. Dow manufactures epoxy resin intermediates including bisphenol A and epichlorohydrin. Saran resins and films are based on polyvinylidene chloride (PVDC).

The Performance Chemicals (17 percent of sales) segment produces chemicals and materials for water purification, pharmaceuticals, paper coatings, paints and advanced electronics. Major product lines include nitroparaffins, such as nitromethane, used in the pharmaceutical industry and manufactured by Angus Chemical Company, a wholly owned subsidiary of The Dow Chemical Co. Important polymers include Dowex ion exchange resins, acrylic and polystyrene latex, as well as Carbowax polyethylene glycols. Specialty chemicals are used as starting materials for production of agrochemicals and pharmaceuticals.

Dow Water and Process Solutions (DW&PS) is a business unit which manufactures Filmtec reverse osmosis membranes which are used to purify water for human use in the Middle East. The technology was used during the 2000 Summer Olympics and 2008 Summer Olympics. The DW&PS business unit remained with DowDuPont following the April 2019 spin off.

Agricultural Sciences, or (Dow AgroSciences), provides 7 percent of sales and is responsible for a range of insecticides (such as Lorsban), herbicides and fungicides. Seeds from genetically modified plants are also an important area of growth for the company. Dow AgroSciences sells seeds commercially under the following brands: Mycogen (grain corn, silage corn, sunflowers, alfalfa, and sorghum), Atlas (soybean), PhytoGen (cotton) and Hyland Seeds in Canada (corn, soybean, alfalfa, navy beans and wheat). The Dow AgroSciences business unit was spun off into Corteva Inc, on 3 June 2019.

Basic plastics (26 percent of sales) end up in everything from diaper liners to beverage bottles and oil tanks. Products are based on the three major polyolefins – polystyrene (such as Styron resins), polyethylene and polypropylene.

Basic chemicals (12 percent of sales) are used internally by Dow as raw materials and are also sold worldwide. Markets include dry cleaning, paints and coatings, snow and ice control and the food industry. Major products include ethylene glycol, caustic soda, chlorine, and vinyl chloride monomer (VCM, for making PVC). Ethylene oxide and propylene oxide and the derived alcohols ethylene glycol and propylene glycol are major feedstocks for the manufacture of plastics such as polyurethane and PET.

The Hydrocarbons and Energy operating segment (13 percent of sales) oversees energy management at Dow.

In 2003, Dow agreed to pay $2 million, the largest penalty ever in a pesticide case, to the state of New York for making illegal safety claims related to its pesticides. The New York Attorney General's Office stated that Dow AgroSciences had violated a 1994 agreement with the State of New York to stop advertisements making safety claims about its pesticide products. Dow stated that it was not admitting to any wrongdoing, and that it was agreeing to the settlement to avoid a costly court battle. According to the United States Environmental Protection Agency (EPA), Dow has some responsibility for 96 of the United States' Superfund toxic waste sites, placing it in 10th place by number of sites. One of these, a former UCC uranium and vanadium processing facility near Uravan, Colorado, is listed as the sole responsibility of Dow. The rest are shared with numerous other companies. Fifteen sites have been listed by the EPA as finalized (cleaned up) and 69 are listed as "construction complete", meaning that all required plans and equipment for cleanup are in place. In 2007, the chemical industry trade association – the American Chemical Council – gave Dow an award of 'Exceptional Merit' in recognition of longstanding energy efficiency and conservation efforts. Between 1995 and 2005, Dow reduced energy intensity (BTU per pound produced) by 22 percent. This is equivalent to saving enough electricity to power eight million US homes for a year. The same year, Dow subsidiary, Dow Agrosciences, won a United Nations Montreal Protocol Innovators Award for its efforts in helping replace methyl bromide – a compound identified as contributing to the depletion of the ozone layer. In addition, Dow Agrosciences won an EPA "Best of the Best" Stratospheric Ozone Protection Award. The United States Environmental Protection Agency (EPA) named Dow as a 2008 Energy Star Partner of the Year for excellence in energy management and reductions in greenhouse gas emissions.

In July 2010, Dow became a worldwide partner of the Olympic Games. The sponsorship extended until 2020. In September 2004, Dow obtained the naming rights to the Saginaw County Event Center in Saginaw, Michigan; the center is now called the Dow Event Center. The Saginaw Spirit (of the Ontario Hockey League) plays at the center, which also hosts events such as professional wrestling, live theater, and concerts. In October 2006, Dow bought the naming rights to the stadium used by the Great Lakes Loons, a Single A minor league baseball team located in its hometown of Midland, Michigan. The stadium is called Dow Diamond. The Dow Foundation played a key role in bringing the Loons to the city. In 2010, Dow signed a $100m (£63m) 10 year deal with the International Olympic Committee and agreed to sponsor the £7m Olympic Stadium wrap. Since 2014 Dow also sponsors Austin Dillon's #3 Chevrolet for Richard Childress Racing in the NASCAR Cup Series.

On 20 May 2013, Dow launched the Dow Lab Safety Academy, a website that includes a large collection of informational videos and resources that demonstrate best practices in laboratory safety. The goal of the website is to improve awareness of safety practices in academic research laboratories and to help the future chemical workforce develop a safety mindset. As such, the Dow Lab Safety Academy is primarily geared toward university students. However, Dow has made the content open to all, including those already employed in the chemical industry. The Dow Lab Safety Academy is also available through the Safety and Chemical Engineering Education program, an affiliate of American Institute of Chemical Engineers (AIChE); and The Campbell Institute, an organization focusing on environment, health and safety practices. The Dow Lab Safety Academy is one component of Dow's larger laboratory safety initiative launched in early 2012, following a report from the U. S. Chemical Safety Board that highlighted the potential hazards associated with conducting research at chemical laboratories in academic institutions. Seeking to share industry best practices with academia, Dow partnered with several U. S. research universities to improve safety awareness and practices in the departments of chemistry, chemical engineering, engineering and materials. Through the pilot programs with U. C. Santa Barbara (UCSB), University of Minnesota, and Pennsylvania State University, Dow worked with graduate students and faculty to identify areas of improvement and develop a culture of laboratory safety.

In January 2011, The Nature Conservancy and The Dow Chemical Co. announced a collaboration to integrate the value of nature into business decision making. Scientists, engineers, and economists from The Nature Conservancy and Dow are working together at three pilot sites (North America, Latin America, and TBD) to implement and refine models that support corporate decision making related to the value and resources nature provides. Those ecosystem services include water, land, air, oceans and a variety of plant and animal life. These sites will serve as a “living laboratories”, to validate and test methods and models so they can be used to inform more sustainable business decisions at Dow and hopefully influence the decision making and business practices of other companies.
