metallikierrätykseen

Metallikierrätys, also known as metal recycling, is the process of reprocessing discarded metal into new products. This practice is crucial for conserving natural resources, reducing energy consumption, and minimizing the environmental impact associated with mining and manufacturing virgin metals.

The recycling process typically begins with the collection and sorting of scrap metal. This can include a wide variety of materials such as steel, aluminum, copper, brass, and lead, originating from sources like old vehicles, construction waste, household appliances, and industrial byproducts. Once sorted by metal type, the scrap is often shredded or crushed to prepare it for further processing.

A key stage in metallikierrätys is smelting, where the sorted metal is melted down at high temperatures. This molten metal is then purified to remove any contaminants. After purification, the metal is cast into ingots or other forms, ready to be used by manufacturers in the production of new goods.

The benefits of metallikierrätys are significant. For instance, recycling aluminum requires up to 95% less energy than producing it from raw bauxite ore. Similarly, steel recycling saves substantial amounts of energy and reduces greenhouse gas emissions compared to primary steel production. By diverting metal waste from landfills, recycling also helps to conserve valuable land space and prevent potential soil and water contamination. The economic advantages include job creation in collection, processing, and manufacturing sectors.
