ABSTRACT

Norfolk Island is located in the Pacific Ocean and lies between Australia, New Zealand and New Caledonia. Norfolk Island is a self-governing territory of Australia under the Norfolk Island Act 1979. Norfolk Island depends on imported diesel for running its primary electricity producing power plant. The cost of imported fuel determines the cost of electricity on the island. The freight costs of shipping diesel to Norfolk Island are high. The Cascade Soft Drink Factory on Norfolk Island is a good example of material recycling and reuse. The factory has a rainwater tank for harvesting rainwater. The triple-bottom-line analysis reveals that the factory performs better than other soft drink industries in terms of environmental impacts. The use of pig effluent for producing biogas greatly reduces water and air pollution, thereby maintaining environmental quality and promoting sustainable development. The solid component left after extracting the biogas from the manure is used as a fertilizer for the soil.
