Recycling is one of the most feel-good and useful
environmental practices around. The benefits go way
beyond reducing piles of garbage, recycling protects
habitat and biodiversity, and saves energy, water, and
resources such as trees and me
Abstract:
As the garbage are increasing and the students are throwing regular garbage in the
recycle bins which makes it harder to distinguish between recyclable and nonrecyclable disposals causing money, time and resources wastage. Solutions must be
