The chemicals industry harvests and manufactures a wide range of products, which they then sell to a large variety of customers in the industrial, agricultural, construction, textile, healthcare, and consumer products sectors. Basic chemicals they produce include petrochemicals, industrial gases, dyes and pigments, alkalies and chlorine, alcohols, and various other organic (based on the chemistry of carbon and oxygen) and inorganic chemicals. Basic chemicals are used to produce intermediate products like polyethylene; polyethylene oxide (PO); ethylene oxide (EO); and ethylene glycol, or final products like phosphate and nitrogen agricultural fertilizers. These basic and intermediate chemicals (often called commodity chemicals) are used to produce more complicated chemicals, known as specialty chemicals, which include resins, plastics, synthetic fibers, pesticides, lubricants, paints, coatings, adhesives, soaps and cleaners, pharmaceuticals, and a huge number of other products with special applications.
This industry sector includes organizations in the oil and gas, power and utilities, chemicals, mining, and forestry industries, who extract and produce energy and other products from natural resources (sub-soil, land, forests, water and wildlife) and associated energy resources (oil, gas, coal, electricity, nuclear resources).
