I WONDER - What Is The World's Most Recycled Material?

Steel is a highly durable and recyclable material, making it one of the most recycled materials globally. In North America alone, 60 to 80 million tons of scrap steel are recycled annually. Recycling steel is energy-efficient, requiring 60% less energy than producing new steel from iron ore. As a result, most steel objects we use are likely made from recycled steel.

What makes steel one of the most recycled materials in the world?

• Its lightweight properties

• Its durable properties

• Its high cost

• Its rarity

Approximately how much scrap steel is recycled annually in North America?

• 10 to 20 million tons

• 30 to 50 million tons

• 60 to 80 million tons

How much less energy does it take to recycle steel compared to manufacturing it from iron ore?

• 60% less

• 80% less

• 40% less

• 20% less

Why is it likely that an object made from steel is actually recycled?

• Because recycled steel is stronger

• Because steel is the most recycled material in the world

• Because recycled steel is cheaper

• Because new steel is rarely produced
