What are the three materials mandated for separation by the 1987 recycling act?

The correct answer highlights the specific types of materials designated for separation under the 1987 recycling act. This act was a significant legislative measure aimed at increasing recycling rates and promoting environmental sustainability. The inclusion of newspaper, glass, and cans in the recycling process was crucial because they represent some of the most commonly used materials that contribute to waste.

Newspaper is a staple in most households and offices, and recycling it reduces the demand for new paper production, therefore conserving natural resources. Glass is another widely used material, often found in containers for beverages and food, which can be recycled indefinitely without losing quality. Cans, typically made from aluminum or steel, are also prevalent and easy to recycle, requiring significantly less energy to process compared to producing new cans from raw materials.

The other options include materials that may be recyclable but do not accurately reflect the mandates established by the 1987 act. Understanding these specific materials helps in implementing more effective recycling programs and guiding public awareness campaigns to promote proper waste separation practices.
