Waste minimization provides financial benefits in terms of reduced transportation cost, less disposal cost, minimized purchase quantity and price of raw materials, reduced purchase price of new materials when considering reuse and recycling, increased returns achieved by selling waste materials etc. Environmental benefits consist of minimized amounts of waste disposed off at landfills, which therefore extend the lifespan of landfills, reduced environmental effects as a result of disposal, e.g. noise, pollution, and decreasing global warming. Other benefits include increased site safety, enhanced work efficiency and productivity and improved image of the company Models of Waste Management In this section we will show briefly some of the waste…show more content…
5. Investment in C&D waste management Investment in C&D waste management can help promote waste management practices in many ways by assigning workers responsible for on-site waste collection, sorting and handling, purchasing equipment and machines for waste management, developing and implementing waste management plans, motivating practitioners to minimize C&D waste and improving operatives’ skills of waste handling through vocational training. The financial reward of this model was perceived as a key incentive driving waste reduction during a construction project . 6. Site space for performing waste management Site space refers to the space used for on-site waste collection, sorting and handling. Since C&D waste is often the mixture of inert and organic materials, and mixed and contaminated waste is not suitable for reuse or recycling but generally disposed of at landfills directly , on-site sorting is effective in achieving a higher rate of waste reuse and recycling. According to Yuan (2013) site space was found to be one of the most important factors when selecting on-site sorting schemes. Without a space layout pre-planned for waste collection and sorting, the temporary placement of sorting facilities and implementation of waste collection and sorting activities might disarrange other construction…show more content…
7. The waste contractor The use of a waste contractor or waste transportation firm with a primary responsibility to provision of waste collection bins and labelling of the bins to suit the waste stream identified in the contractor’s waste management plan is highly recommended . The waste material can become the property of the waste removal contractor and any rebates paid on recyclable products should be made to the account of the waste removal contractor. 8. Eliminating Waste This model is also known as designing out waste, which is the technique of minimizing waste by avoiding, eliminating, and reducing waste at its source. Designing out waste at the earliest stages of the construction process offers the greatest opportunities for waste minimization . Some waste generated in the process of construction can be eliminated by using durable modular metal form systems for use in concrete construction may be selected on the basis of being readily demountable and reusable on other projects. Eliminating wood waste associated with formwork fabricated of plywood and dimensional lumber can be beneficial to reduce impacts on human health and the environment. Reducing waste means more efficient use of materials by adopting efficient practices,
