A factor that is considered most important when siting a chemical industry is?

Analyze the question: It asks which factor matters most when choosing a location (siting) for a chemical industry.

Explain the concept: Industrial location depends on several factors: raw materials, power, labour, transport, market, water, and government policy. For chemical industries, the raw materials are usually bulky, heavy, or costly to transport. Some are also hazardous or perishable. Locating the plant near its raw materials therefore cuts transport costs and reduces losses, which makes production more economical.

Solution, option by option:

• A. Nearness to other industrial establishments: This can help, but it is not the main factor. It is a secondary advantage, not a necessity.
• B. Nearness to raw materials: This is the most important factor. The raw materials are the foundation of production, and the cost of moving them heavily affects profit. Examples are cement plants sited near limestone, such as Ewekoro, and petrochemical plants near crude oil sources in the Niger Delta.
• C. Favourable climate conditions: Climate matters little for most chemical processes, since they take place in controlled plants.
• D. Availability of storage facilities: Useful, but these can be built anywhere, so this is not the deciding factor.

Exam tip: When a question asks for the "most important" factor in siting an industry, think "raw materials first." This is especially true for industries whose raw materials are bulky and whose finished product weighs less (weight-losing industries). Remember it as: "No raw materials, no products."
