Electricity trading enhances grid stability, encourages competition, reduces prices, and makes renewable energy integration easier in global energy markets. Electricity trading refers to the buying and selling of electricity among participants in the electricity industry, such as independent power producers, open-access consumers, and municipality-owned utilities. Various forms of electricity trading are possible depending on market design, ranging from short-term trading to long-term trading. Electricity can be traded on exchanges, over the counter (OTC) with an intermediary, and directly OTC with no intermediary.

Electronic waste (e-waste) is any discarded electrical or electronic equipment. This applies to electrical or electronic equipment, which is either still functional or damaged and has been discarded as garbage. Electronic waste recycling is the process of extracting valuable materials, which can be reused in a new electronic appliance, after shredding the e-waste into tiny pieces. Some of these materials contain cadmium, lead, mercury, chromium, and other materials.

An elevator is a vertical transportation vehicle that facilitates the movement of people or goods between various floors of a building or other multi-story structure.

Epoxy resins are a versatile class of synthetic polymers known for their exceptional adhesive properties, mechanical strength, and chemical resistance. Defined by their ability to form cross￾linked networks upon curing, these resins are used in various applications across various industries. Epoxy resin is superior to other resins because it has low shrink during cure and excellent moisture and chemical resistance. It is impact-resistant, has good electrical and insulation properties, and has a long shelf life.
