The energy consumption of the resources of each sugar life cycle is shown in Figure 2. Sugar mills have the potential to produce electricity through the burning of bagasses which produces steam in the boiler [13].

The crushed coal is then transported to the store yard. Coal is transported to bowl mills by coal feeders. 3. Bowl Mill. The coal is pulverized in the bowl mill, where it is grounded to a powder form. The mill consists of a round metallic table on which coal particles fall. This table is rotated with the help of a motor.

Raw materials Steel production. Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then 'purified' or 'carbonised' in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.

The bitumen in the coal binds it into lumps in a coke oven. Coking coal is higher in carbon content than cheaper coals and lignite which are used in power stations and industrial boilers. New Zealand's Glenbrook Steel plant uses a different process. It is a unique design, developed to use NZ iron sands and sub-bituminous coal from Huntly.
