The process of recycling scrap metal in Brisbane typically follows these steps:
- Collection & Sorting: Scrap metal is collected from various sources, including households, commercial businesses, and industrial sites. Many scrap yards in Brisbane offer drop-off services or even free pick-up for larger commercial quantities. Once at the facility, the metals are sorted into two primary categories: ferrous and non-ferrous.
- Ferrous metals contain iron and are magnetic, such as steel and cast iron.
- Non-ferrous metals don’t contain iron and aren’t magnetic, including valuable metals like copper, aluminum, brass, and lead.
- Processing: After sorting, the metals are processed to prepare them for melting. This involves compacting, shearing, or shredding the metal to reduce its size and density. Large hydraulic shears can cut through heavy steel, while shredders break down smaller items like car bodies and appliances. This step makes the material easier and more efficient to transport and melt.
- Melting & Purification: The processed scrap metal is then melted down in large industrial furnaces. Different types of metals have specific furnaces designed for their properties. Once melted, the molten metal is purified to remove any impurities.
- Re-casting & Manufacturing: The purified, molten metal is then poured into molds to create new products, such as billets, ingots, or sheets. These are then sold to manufacturers for a wide range of uses, from new construction materials and car parts to beverage cans.
Types of Scrap Metal and Current Prices
Scrap metal prices fluctuate daily based on global market demand. The value of your scrap depends on the type, quantity, and cleanliness of the metal. Generally, non-ferrous metals fetch a much higher price than ferrous metals.
- Ferrous Metals: Steel and iron (often found in white goods and car bodies). Prices are relatively low.
- Non-Ferrous Metals:
- Copper: Highly valuable, found in wiring, pipes, and motors.
- Aluminum: Common in cans, window frames, and car parts.
- Brass: Found in plumbing fixtures and fittings.
- Lead: Used in batteries and roofing.
- Stainless Steel: Used in appliances and kitchenware.

Environmental and Economic Benefits ♻️
Recycling scrap metal is crucial for environmental sustainability and economic growth in Brisbane.
- Environmental Protection: It significantly reduces the need for raw material mining, which is a highly energy-intensive and environmentally destructive process. By recycling, we conserve finite natural resources and reduce pollution from mining and refining. For example, recycling steel uses about 60-74% less energy than making it from raw ore, and aluminum recycling saves a massive 95% of the energy needed for new production. This also leads to a reduction in greenhouse gas emissions.
- Resource Conservation: Metals like aluminum and steel can be recycled indefinitely without losing their quality. This extends the lifespan of these valuable materials and reduces the amount of waste sent to landfills.
- Economic Impact: The recycling industry creates local jobs in collection, processing, and manufacturing. Furthermore, selling scrap metal provides a financial incentive for individuals and businesses to responsibly dispose of their waste, turning unwanted materials into a valuable commodity.
