1 Introduction Waste management is the collection, transport, processing, recycling or disposal, and monitoring of waste materials. The term usually relates to materials produced by human activity, and is generally undertaken to reduce their effect on health, the environment or aesthetics. Waste management is also carried out to recover resources from it. Waste management can involve solid, liquid, gaseous or radioactive substances, with different methods and fields of expertise for each. Waste management practices differ for developed and developing nations, for urban and rural areas, and for residential and industrial producers. Management for non-hazardous residential and institutional waste in metropolitan areas is usually the responsibility of local government authorities, while management for nonhazardous commercial and industrial waste is usually the responsibility of the generator [7], [11], [24]. All organisms produce wastes, but none produces as many wastes of such diverse composition as humans. Society's wastes arise from many different activities; growth is worldwide still accompanied by increasing amounts of waste, causing unnecessary losses of materials and energy, environmental damage and negative effects on health and quality of life. It is a strategic goal of most developed countries to reduce these negative impacts, meaning to reduce waste or applying a correct management system to exploit it, turning into novel technologies, opportunities of
business, and offering new jobs and further advantages for the community that is generating it.
