Final answer:
Source reduction is the preferred method of waste management because it prevents pollution from occurring at its origin, conserves natural resources, saves energy, and reduces costs associated with pollution control and material consumption.
Step-by-step explanation:
Source reduction is the most preferred approach to waste management because it addresses waste issues at the origin, leading to numerous environmental, economic, and societal benefits. The P2 Act emphasizes the importance of reducing or preventing pollution at the source, which is more cost-effective than dealing with pollution after it has been created. By altering production, operation, and raw materials use, source reduction can prevent pollution from entering waste streams or the environment, reducing the need for recycling, treatment, or disposal.
Source reduction not only conserves natural resources like timber, water, and minerals but also enhances economic security by using domestic materials. By preventing the need for new raw materials, it reduces pollution, saves energy, and leads to substantial savings for industries in terms of materials, pollution control, and liability costs. Additionally, it decreases the volume of waste that is sent to landfills and incinerators, thereby contributing to a more sustainable environment.
