Why is paper recycling considered an environmentally beneficial practice?
AIt uses more water than making new paper
BIt contaminates the water supply
CIt saves trees and reduces the energy and water demand of producing virgin paper; paper can be recycled 5–7 times before its fibres become too short to reuse
DIt requires no electricity
Answer & Solution
Correct answer: C. It saves trees and reduces the energy and water demand of producing virgin paper; paper can be recycled 5–7 times before its fibres become too short to reuse
Each recycling cycle saves about 17 trees per tonne of paper recycled, plus large amounts of energy, water, and forest land. The same paper can typically be recycled 5–7 times before the cellulose fibres become too degraded for further use. So even a few cycles of recycling significantly reduce environmental impact.
