**Sulphur (Sulfur)**

Sulphur, also spelled sulfur, is a chemical element with the symbol S and atomic number 16. It is a nonmetal and is abundant, multivalent, and nonmetallic. In its native form, sulphur is a bright yellow crystalline solid at room temperature. Historically known for its flammability, sulphur burns with a blue flame and emits a distinctive odor — the smell of burning matches is due to sulfur.

In the energy commodities trading sector, sulphur is significant because it is a byproduct of the refining process of fossil fuels such as petroleum and coal, where it is removed due to its corrosive effects and environmental impact when burnt and released into the atmosphere. The removed sulphur is often sold and used in the production of a wide range of products, including fertilizers, chemicals, pharmaceuticals, and in the vulcanization of rubber.

The trading of sulphur as a commodity is dictated by supply and demand dynamics, where the production is influenced by the activities in the energy sector, and the demand is driven by the agricultural sector and industrial uses. Sulphur prices can be subject to volatility due to economic factors, technological advancements, and regulatory policies aimed at sulfur emissions.
