Workshop WeldingRecyclability & Renewable Energy

  1. Almost 69 percent of steel is recycled in North America each year, which is more than paper, aluminium, plastic, and glass combined.
  2. More than 80 million tons of steel are recycled in North America every year.
  3. Steel is roughly 1,000 times stronger than iron in its purest form, and it can be recycled without loss of strength.
  4. Steel is the main material used in delivering renewable energy like solar, hydro, and wind power.
  5. Since world war II, the north American steel industry has reduced its energy use by 60 percent, which has contributed to a significant reduction in carbon dioxide generation.

Global Involvement

  1. In developing countries, steel companies are the most involved trade with the provision of healthcare services and community-wide education.
  2. The steel industry has an estimated £900 billion turnover, making it the second largest industry in the world after oil and gas.
  3. Steel is used in almost every industry, including energy, construction and housing (the largest consumer of steel), automotive and transportation, infrastructure, packing, and machinery.
  4. The top 10 leading producers of steel to date are as follows, China, Japan, India, USA, Russia, South Korea, Germany, Turkey, Brazil and Ukraine.
  5. The steel industry directly employs more than 2 million people worldwide and continues to grow each year.

Steel Projects

  1. Steel roofs last more than 50 years while traditional roofs last about 17 years.
  2. 75% of all major appliances are comprised of steel.
  3. The average computer is about 25% steel.
  4. Steel was first used for skyscrapers in 1884 with the Home Insurance Building in Chicago. Modern steel buildings, like The Empire State Building (1930) in New York and the U.S. Steel Tower (1971) in Pittsburgh, are designed to easily assemble and disassemble.

  7. Steel bridges are 4-8 times lighter than those built from concrete. The Golden Gate Bridge (1937) required 83,000 tons of steel whereas half of that amount would be required today.
  8. Two-thirds of all canned goods packaging are made out of steel.
  9. More than 600 steel cans are recycled every second in the United States.
  10. Recycling a single steel can saves enough energy to power a 60-watt light bulb for almost 4 years.

There are many more facts that can be said about steel, I find that when working in the fabrication industry, no matter how much experienc you have you still learn new things everyday!
