Central Chemical Corp.

History of Central Chemical Corp.
In important ways, the circumstances surrounding Thomas’s entry into the fertilizer business were not propitious. First, Thomas began business near the end of a half-century-long relocation of the fertilizer industry’s center. Though fertilizer use continued to increase in the Mid-Atlantic states and elsewhere during the period from 1870 to 1920, the manufacture of fertilizer began to shift to the Southern states in the late nineteenth century. By 1902, Charleston had replaced Baltimore as the fertilizer capital of the country. The Mid-Atlantic states’ share of total fertilizer use decreased from 34% in 1880 to 14% in 1920. By contrast, in 1920 the South-Atlantic states used about 50% of all fertilizers consumed in the U.S. Thus, Hagerstown could no longer enjoy proximity to the major centers of fertilizer-material production, and, while previously situated between the two highest-fertilizer-use regions of the country, it now found itself on the northern edge of a region that now dwarfed all others.

Second, Thomas’s decision to continue in the practice (apparently favored by Hagerstown companies) of making fertilizer primarily from bone and organic materials came at the start of a rapid increase in the demand for mixed fertilizers, but also at the beginning of a precipitous decline in the use of bone and bone products as a source of phosphorous in fertilizers. With the growing use of potash and phosphate rock, consumption of mixed fertilizers grew from 46% of the total in 1880 to around 70% in 1920. During the period from 1890 to 1910, when Thomas was focusing on his presumably unmixed “dissolved bone” fertilizers, mixed fertilizers were capturing market share.

Furthermore, the period from 1880 to 1920 is also characterized by the decreasing use of organic materials in general. Though organic materials provided about 91% of the total nitrogen in 1900, by 1917 the total nitrogen contribution from organics had dropped to 46.5%. With regard to phosphates, bone meal, dissolved bones and boneblack, and phosphoro-guano use peaked in 1890, but their use dropped to a negligible amount by 1910 as the use of superphosphates from phosphate rock increased dramatically..

Third, even as Thomas had begun his business trading fertilizer for livestock from relatively distant places, the fertilizer industry was increasingly turning to local distribution. Though mid-nineteenth-century fertilizer plants typically were situated in East Coast harbor cities, twentieth-century plants were dispersed to be closer to areas of consumption.

Finally, even though the name “Thomas’ Dissolved Bone” suggests that Thomas produced his own superphosphates initially, the use of bone in the production of superphosphates was on its way out as described above. For all practical purposes, then, Thomas had set his business on the track of the second, smaller type of fertilizer company, which only mixed fertilizer and did not produce superphosphates. For the next 90 years, even when Central Chemical had affiliates across the nation, it would remain in this “smaller” category – relying on large suppliers for its materials. For reasons noted above, this was not a problem at the turn of the century vis-à-vis the larger companies. Starting in the 1890s, however, many agricultural societies began to advocate home mixing of fertilizer materials by farmers. Throughout the first half of the twentieth century, the fertilizer industry fought this effort successfully by insisting on the value of industrial mixing processes and the farmer’s comparative disadvantages in mixing.

Though in its early years, Central Chemical advertised itself as “Exporters – Manufacturers – Importers,” by the 1970s it had become little more than a middle-man between larger suppliers and farmers. It did not import its own materials, but purchased granulated materials from suppliers. There is no evidence that Central Chemical was exporting products out of the country anymore. And its manufacturing capacity consisted of mixing pre-processed granulated materials in various proportions. At this point, its consulting capacity became equally important to its factory processes.

Though Central Chemical and its subsidiaries were taking in a combined $25 million in sales by the late 1970s, an employee remembers that there was always a sense of trouble on the horizon. The vulnerability of a company that adds very little value to its product and relies entirely on contracts with larger suppliers requires no explanation. It appears that not long after Central Chemical became a bulk blender, its large suppliers began pushing their advantages. In the early 70s, Central Chemical’s supplier, Agrico Chemical Company, put pressure on Central Chemical to enter into a long-term contract. When Central Chemical refused, Agrico withheld di-ammonium phosphate and granular triple super phosphate at a time of national shortage in these materials. Central Chemical responded by filing an antitrust lawsuit against Agrico in federal court. For most of the next decade much of the time, resources, and energy of what was still a closely-held corporation would be consumed in this litigation. Ultimately the lawsuit proved unsuccessful.

All of this came at the same time that local, state, federal regulators were investigating the Hagerstown plant for its pesticide-disposal practices. In the 1970s the State of Maryland ordered two separate cleanups of the site; the EPA was just getting started.

Ultimately the push to eliminate the middle man that drove the switch to bulk blending began to turn on the blenders themselves. The larger companies and farmers wised up, and realized that they could both save money by dealing directly with each other. Farmers began buying direct-application materials from the same suppliers used by Central Chemical. By the early 1980s, Central Chemical’s network of fertilizer blenders had contracted substantially. Blending operations like those of the Hagerstown plant could no longer make the case for themselves. Crushed under the weight of increasingly serious environmental liability for its mid-century disposal practices, the Central Chemical Corporation contracted its operations substantially. The Hagerstown plant ceased operations in 1984 and the office headquarters moved from the old Thomas building to an office outside Hagerstown.

Facts About Ricin (Castor Pomace) By Ken Buckler

By Ken Buckler
A report of fertilizer manufacturers shows that Central Chemical was producing "Castor Pomace".
Here is a document from the EPA regarding the castor bean dust which would have been created while creating this fertilizer.
I do not have data on when Central Chemical stopped producing Castor Pomace.

What ricin is

  • Ricin is a poison found naturally in castor beans. If castor beans are chewed and swallowed, the released ricin can cause injury.  Ricin can be made from the waste material left over from processing castor beans.
  • It can be in the form of a powder, a mist, or a pellet, or it can be dissolved in water or weak acid.
  • It is a stable substance under normal conditions, but can be inactivated by heat above 80 degrees centigrade (176 degrees Fahrenheit).

Where ricin is found and how it is used

  • Castor beans are processed throughout the world to make castor oil. Ricin is part of the waste “mash” produced when castor oil is made.
  • Ricin has been used experimentally in medicine to kill cancer cells.

How you could be exposed to ricin

  • It would take a deliberate act to make ricin and use it to poison people. Unintentional exposure to ricin is highly unlikely, except through the ingestion of castor beans.
  • If made into a partially purified material or refined into a terrorist or warfare agent, ricin could be used to expose people through the air, food, or water.
  • In 1978, Georgi Markov, a Bulgarian writer and journalist who was living in London, died after he was attacked by a man with an umbrella. The umbrella had been rigged to inject a poison ricin pellet under Markov’s skin.
  • In the 1940s the U.S. military experimented with using ricin as a possible warfare agent. In some reports ricin has possibly been used as a warfare agent in the 1980s in Iraq and more recently by terrorist organizations.
  • Ricin poisoning is not contagious. Ricin-associated illness cannot be spread from person to person through casual contact. However, if you come into contact with someone who has ricin on their body or clothes, you could become exposed to it.

How ricin works

  • Ricin works by getting inside the cells of a person’s body and preventing the cells from making the proteins they need. Without the proteins, cells die. Eventually this is harmful to the whole body, and death may occur.
  • Effects of ricin poisoning depend on whether ricin was inhaled, ingested, or injected.

Signs and symptoms of ricin exposure

  • The major symptoms of ricin poisoning depend on the route of exposure and the dose received, though many organs may be affected in severe cases.
  • Initial symptoms of ricin poisoning by inhalation may occur as early as 4- 8 hours and as  late as 24 hours after exposure. Following ingestion of ricin, initial symptoms typically occur in less than 10 hours.
  • Inhalation: Within a few hours of inhaling significant amounts of ricin, the likely symptoms would be respiratory distress (difficulty breathing), fever, cough, nausea, and tightness in the chest. Heavy sweating may follow as well as fluid building up in the lungs (pulmonary edema). This would make breathing even more difficult, and the skin might turn blue. Excess fluid in the lungs would be diagnosed by x-ray or by listening to the chest with a stethoscope. Finally, low blood pressure and respiratory failure may occur, leading to death. In cases of known exposure to ricin, people having respiratory symptoms should seek medical care.
  • Ingestion: If someone swallows a significant amount of ricin, he or she would likely develop vomiting and diarrhea that may become bloody. Severe dehydration may be the result, followed by low blood pressure. Other signs or symptoms may include seizures, and blood in the urine. Within several days, the person’s liver, spleen, and kidneys might stop working, and the person could die.
  • Skin and eye exposure: Ricin is unlikely to be absorbed through normal skin. Contact with ricin powders or products may cause redness and pain of the skin and the eyes. However, if you touch ricin that is on your skin and then eat food with your hands or put your hands in your mouth, you may ingest some. 
  • Death from ricin poisoning could take place within 36 to 72 hours of exposure, depending on the route of exposure (inhalation, ingestion, or injection) and the dose received.

How authorities confirm cases of suspected ricin poisoning

  • If authorities suspect that people have inhaled ricin, a potential clue would be that a large number of people who had been close to each other rapidly developed fever, cough, and excess fluid in their lungs. These symptoms would likely be followed by severe breathing problems and possibly death.
  • If in suspected situations where ricin may have been disseminated, preliminary environmental testing by public health or law enforcement authorities detects ricin in powders or materials released into the immediate environment. Persons occupying such areas may initially be observed for signs of ricin poisoning.
  • CDC can assess selected specimens on a provisional basis for urinary ricinine, an alkaloid in the castor bean plant. Only urinary ricinine testing is available at CDC or the LRN. 

How ricin poisoning is treated

  • Because no antidote exists for ricin, the most important factor is avoiding ricin exposure in the first place.
  • If exposure cannot be avoided, the most important factor is then getting the ricin off or out of the body as quickly as possible.
  • Symptomatic ricin poisoning is treated by giving victims supportive medical care to minimize the effects of the poisoning. The types of supportive medical care would depend on several factors, such as the route by which victims were poisoned (that is, whether poisoning was by inhalation, ingestion, or skin or eye exposure). Care could include such measures as helping victims breathe, giving them intravenous fluids (fluids given through a needle inserted into a vein), giving them medications to treat conditions such as seizure and low blood pressure, flushing their stomachs with activated charcoal (if the ricin has been very recently ingested), or washing out their eyes with water if their eyes are irritated.

How you can protect yourself, and what to do if you are exposed to ricin

  • Get fresh air right away by leaving the area where the ricin was released.
    • If the ricin release was outside, move away from the area where the ricin was released.
    • If the ricin release was indoors, get out of the building.
  • If you are near a release of ricin, emergency coordinators may tell you to either evacuate the area or to “shelter in place” inside a building to avoid being exposed to the chemical. For more information on evacuation during a chemical emergency, see Facts About Evacuation. For more information on sheltering in place during a chemical emergency, see Facts About Sheltering in Place.
  • If you think you may have been exposed to ricin, you should remove your clothing, rapidly wash your entire body with soap and water, and get medical care as quickly as possible.
  • Removing your clothing:
    • Quickly take off clothing that may have ricin on it. Any clothing that has to be pulled over the head should be cut off the body instead of pulled over the head.
    • If you are helping other people remove their clothing, try to avoid touching any contaminated areas, and remove the clothing as quickly as possible.
  • Washing yourself:
    • As quickly as possible, wash any ricin from your skin with large amounts of soap and water. Washing with soap and water will help protect people from any chemicals on their bodies.
    • If your eyes are burning or your vision is blurred, rinse your eyes with plain water for 10 to 15 minutes. If you wear contacts, remove them and put them with the contaminated clothing. Do not put the contacts back in your eyes (even if they are not disposable contacts). If you wear eyeglasses, wash them with soap and water. You can put your eyeglasses back on after you wash them.
  • Disposing of your clothes:
    • After you have washed yourself, place your clothing inside a plastic bag. Avoid touching contaminated areas of the clothing. If you can't avoid touching contaminated areas, or you aren't sure where the contaminated areas are, wear rubber gloves, turn the bag inside out and use it to pick up the clothing, or put the clothing in the bag using tongs, tool handles, sticks, or similar objects. Anything that touches the contaminated clothing should also be placed in the bag. If you wear contacts, put them in the plastic bag, too.
    • Seal the bag, and then seal that bag inside another plastic bag. Disposing of your clothing in this way will help protect you and other people from any chemicals that might be on your clothes.
    • When the local or state health department or emergency personnel arrive, tell them what you did with your clothes. The health department or emergency personnel will arrange for further disposal. Do not handle the plastic bags yourself.
  • For more information about cleaning your body and disposing of your clothes after a chemical release, see Chemical Agents: Facts About Personal Cleaning and Disposal of Contaminated Clothing.
  • If someone has ingested ricin, do not induce vomiting or give fluids to drink.
  • Seek medical attention right away. Consider dialing 911 and explaining what has happened.
