Exploring The Various Types Of Metals Suitable For Bulk Recycling

Properties:

Aluminium is a lightweight, corrosion-resistant metal with excellent conductivity and malleability. It is widely used in beverage cans, household appliances, car parts, and window frames.

Value in Recycling:

Aluminium is one of the most valuable recyclable metals due to its high demand in industries such as automotive, construction, and packaging. Recycling aluminium uses 95% less energy compared to producing new aluminium, making it an environmentally friendly option.

Sourcing Process:

Common sources of scrap aluminium include soda cans, old bicycles, car rims, foil, window frames, and kitchen utensils. These items are collected, sorted, and melted down for reuse.

Decomposition Time:

Unlike organic materials, aluminium does not biodegrade. If left in landfills, it can take 200 to 500 years to decompose, highlighting the importance of recycling.

Properties:

Copper is known for its excellent electrical conductivity, ductility, and resistance to corrosion. It is widely used in electrical wiring, plumbing, roofing, and industrial machinery.

Value in Recycling:

Copper is one of the most sought-after scrap metals on the Sunshine Coast, offering high returns due to its demand in the electrical and construction industries. It retains its quality even after multiple recycling processes, making it highly sustainable.

Sourcing Process:

Scrap copper can be sourced from old electrical wiring, plumbing pipes, air conditioning units, roofing sheets, and household electronics. Stripped electrical wires contain high-purity copper, which is especially valuable.

Decomposition Time:

If discarded, copper can take more than 1,000 years to decompose. Recycling ensures that this valuable metal is continuously reused instead of wasting away in landfills.

Properties:

Steel is a strong, durable metal with high tensile strength, making it one of the most commonly used materials in construction, transportation, and manufacturing.

Value in Recycling:

Steel is 100% recyclable and can be reused indefinitely without losing its properties. Recycling steel saves up to 75% of the energy required to produce new steel from raw materials.

Sourcing Process:

Steel can be recovered from construction debris, old appliances, car bodies, railway tracks, and industrial equipment. Structural beams, pipes, and containers are some of the largest sources of recyclable steel.

Decomposition Time:

Steel items can take 50 to 500 years to break down in landfills. Recycling steel significantly reduces waste and conserves natural resources such as iron ore.

Properties:

Brass is an alloy of copper and zinc, known for its durability, corrosion resistance, and attractive golden colour. It is commonly used in plumbing fixtures, musical instruments, and decorative hardware.

Value in Recycling:

Due to its high copper content, brass holds considerable value in the scrap metal recycling industry. It is often repurposed into new fittings, electrical components, and ornaments.

Sourcing Process:

Scrap brass can be collected from plumbing pipes, doorknobs, locks, hinges, shell casings, and antique fixtures. It is sorted, melted down, and reshaped for reuse.

Decomposition Time:

Brass can take over 1,000 years to break down, making recycling a crucial alternative for sustainability.

Properties:

Lead is a dense, malleable metal that is commonly found in batteries, old pipes, and radiation shields. However, it is toxic and requires careful handling during the recycling process.

Value in Recycling:

Despite its toxicity, lead is highly recyclable and remains valuable due to its continued use in batteries and protective materials. Recycling lead helps reduce environmental contamination.

Sourcing Process:

Lead is primarily sourced from car batteries, old pipes, X-ray shields, and certain roofing materials. Specialised facilities handle lead recycling safely.

Decomposition Time:

Lead takes hundreds to thousands of years to break down. If not properly disposed of, it poses a risk to soil and water contamination.

Properties:

Stainless steel is an iron-based alloy containing chromium, which makes it highly resistant to rust and corrosion. It is commonly used in kitchen appliances, medical instruments, and industrial equipment.

Value in Recycling:

Since it contains valuable metals such as nickel and chromium, stainless steel is highly sought after in metal recycling. It is 100% recyclable and can be reused in manufacturing without losing its strength.

Sourcing Process:

Stainless steel scrap is sourced from kitchen sinks, cutlery, medical tools, industrial machinery, and automotive parts. The metal is sorted and melted down for reuse.

Decomposition Time:

Stainless steel can take 100 to 1,000 years to decompose, making recycling essential for environmental conservation.
