Energy Needed To Produce Aluminum Today In Energy
Beverage cans and aluminum automotive parts such as engine blocks are two of the most common types of items made from secondary aluminum Aluminum building materials are also recycled Producing secondary aluminum involves cleaning and separating aluminum scrap from other materials and melting it down in a furnace usually fired by natural gas.
Aluminum The Environmental Literacy Council
Aluminum poses no danger of environmental toxicity when soil pH remains at or above 50 however acid rain lowers the pH of soil and forces aluminum into solution This causes it to leach into the water supply where it can damage root systems and create acidified lakes Due to its natural abundance the amount of aluminum that enters the.
