Solid Waste Management

Solid Waste Management is a critical discipline within environmental engineering that encompasses the systematic control of the generation, collection, storage, transportation, processing, and disposal of solid materials discarded from human and animal activities. The primary objective is to manage waste in a manner that is protective of public health, environmentally sustainable, and economically viable. This involves applying engineering principles to design and implement integrated systems that follow a waste hierarchy, prioritizing waste prevention, reuse, recycling, and resource recovery (such as composting or waste-to-energy conversion), with the safe disposal of residual waste in engineered facilities like sanitary landfills as the final option.
