One crucial conversation that must be had about chemical use and its influence on industrialization is the ripple effect on the environment. This part of the article will outline all sides of the discourse- the good, the bad, and the ugly.
The Good: Pollution Contol and Waste Management
- (Example: The 2014 water crisis in Flint, Michigan)
Caustic soda powder plays a pivotal role in environmental management. It’s used in water treatment plants to neutralize acidic waste and make water safe for discharge into natural bodies.
Flashback to 2014 in Flint, Michigan, where lead contamination became a public health crisis after the city changed its water supply. This led to the corrosion of distribution pipes, resulting in one of the worst public health crises in the US. In this case, caustic soda was used to control the corrosivity of the water, which led to the reduction of lead (no pun intended).
This application direction impacts public health and is crucial in regions where water scarcity is an issue.
The Bad: Handling and Disposal Challenges
- (Example: The Love Canal tragedy)
Although it is excellent, caustic soda (and chemicals in general) also has environmental challenges. Due to its corrosive nature, improper handling can lead to environmental hazards like soil contamination. This is why the disposal of caustic soda must be managed carefully to prevent any adverse environmental impact.
The “Love Canal” tragedy of the 70s remains one of American history’s most appalling environmental tragedies. The canal was initially abandoned until it became a dumping ground for more than 20,000 tons of chemical waste produced in the 1940s and 50s by the Hooker Chemical and Plastics corporation.
This resulted in an abnormally high incidence of chromosomal damage among residents and an eventual evacuation. This is one of the many ways improper chemical waste disposal, including caustic soda, can lead to environmental disasters.
The Ugly: Potential for ecological harm
- (Example: The Minamata Disease)
If improperly managed, caustic soda can cause significant ecological harm. It can lead to the death of aquatic life if leaked into water bodies and harm soil quality, affecting agriculture and natural habitats.
This was the case in Japan when a factory in Minamata City released chemicals into Minimata Bay, contaminating it and leading to large-scale methylmercury poisoning. Minamata disease causes irreversible damage to the nervous system. The disease first occurred when toxic chemicals affected the fish that served as food supply for the coastal community in Minimata, Japan.
This tragic event led to stricter regulations and increased global awareness of chemical waste disposal.
Closer to home, in the Niger Delta, caustic soda is used in the refining of crude oil. While it helps the separation process, improper disposal has led to water contamination and soil degradation, affecting local communities and ecosystems. Regulatory bodies like Nigeria’s NESREA are working to enforce stricter guidelines for chemical use and disposal)
