The model was applied to a Lisbon Metropolitan Area case study, which required extensive data collection and estimation.
An overall waste management plan is developed to provide a contractor with a step by step flowchart for analyzing material wastes, quantitatively assessing all costs associated with waste disposal, and implementing and updating the chosen waste management techniques.
A case study is provided to illustrate how the waste management plan is used in an actual project.
Historically, landfilling waste materials was the standard solution for most contractors, but as tipping fees have risen dramatically over the past five to seven years, many contractors are looking for alternative methods, such as recycling or waste minimization, to reduce wastes.
This thesis investigates C&D wastes and proposes a methodology to address the problem of assessing waste disposal techniques efficiently and economically.These wastes include materials such as concrete, bricks, wood and lumber, roofing, drywall, landscape and other wastes.In Minnesota, more than 80 percent of the 1.6 million tons of construction and demolition waste was landfilled in 2013. Regardless of the origin, content or hazard potential, solid waste must be managed systematically to ensure environmental best practices.As solid waste management is a critical aspect of environmental hygiene, it needs to be incorporated into environmental planning.Solutions comprise a small number of high capacity recycling plants, when cost minimization is at stake, while when preference is given to the minimization of environmental impacts solutions comprise several geographically dispersed recycling plants of low capacity.Before introducing solid waste management, let's start with a discussion of the material being managed — solid waste.The primary goal of solid waste management is reducing and eliminating adverse impacts of waste materials on human health and environment to support economic development and superior quality of life.As the field of solid waste management advances, solutions are being looked at in a more systematic and holistic way.Categorization may also be based on hazard potential, including radioactive, flammable, infectious, toxic, or non-toxic.Categories may also pertain to the origin of waste, such as industrial, domestic, commercial, institutional or construction and demolition.
