Final answer:
The EPA does not provide a specific estimate for re-usable waste in landfills, but emphasizes the importance of recycling and reusing waste materials. Recycling and reuse activities in the US provide economic benefits through jobs, wages, and tax revenues. Hazardous waste regulations aim to balance resource conservation and public health protection.
Step-by-step explanation:
The Environmental Protection Agency (EPA) does not provide a specific estimate for how much waste sent to a landfill is re-usable. However, the EPA has emphasized the importance of recycling and reusing waste materials to minimize environmental impact and conserve resources.
According to the EPA, recycling and reuse activities in the United States in a single year accounted for providing jobs, wages, and tax revenues.
In addition, the EPA has developed hazardous waste regulations that aim to balance resource conservation while protecting human health and the environment. Many hazardous wastes can be safely recycled, while others are treated and disposed of in landfills or incinerators.
