Waste hierarchy
Waste hierarchy
The Waste hierarchy (/ˈweɪst ˈhaɪəˌrɑːrki/), also known as the 3 R's, is a concept from Environmental science that prioritizes different waste management strategies based on their environmental impact. The term is believed to have originated in the late 20th century, though its exact etymology is unclear.
The waste hierarchy consists of three main components: Reduce, Reuse, and Recycle. These strategies are designed to minimize the amount of waste that ends up in landfills and to promote sustainable practices.
Reduce
Reduce (/rɪˈdjuːs/) refers to the strategy of minimizing the amount of waste produced in the first place. This can be achieved through various means, such as using less packaging, buying in bulk, or choosing products that are designed to last longer.
Reuse
Reuse (/riːˈjuːz/) involves finding new uses for items that would otherwise be thrown away. This can include repurposing items, donating them to charity, or selling them second-hand.
Recycle
Recycle (/riːˈsaɪkəl/) is the process of converting waste materials into new products. This can include everything from composting organic waste to melting down plastics and metals for reuse.
