Metabronze’s dedication to sustainability is evident in the careful selection of materials for its drainage products, which include bronze, stainless steel, aluminium, cast iron, and uPVC. These high-quality materials are designed for exceptional durability, frequently lasting longer than the buildings in which they are fitted. They are specifically selected for their ability to endure harsh weather conditions with minimal upkeep.
This article offers a concise overview of reusing and recycling SPS and Metabronze Roof and Floor Drain products.
Guidance on Reusing and Recycling SPS and Metabronze Roof and Floor Drains
Roof and floor Drains from SPS and Metabronze are typically made from durable materials, including bronze, cast iron, 316 and 304 grade stainless steel, aluminium, and PVC plastic. Each of these materials offers unique opportunities and considerations for reuse and recycling.
Below is a detailed guide on how to maximise their environmental and economic value at end-of-life.
Bronze
- Reusability: Bronze components, due to their durability and resistance to corrosion, can often be cleaned and reused in new construction or renovation projects, provided they remain structurally sound.
- Recycling: Bronze is a valuable non-ferrous metal and is widely accepted at metal recycling facilities. The recycling process involves collection, sorting, cleaning, and melting to produce new bronze products. Given its high market value, bronze scrap is rarely sent to landfill and is almost always recycled.
Cast Iron
- Reusability: Intact cast iron drains can be reused in projects where their structural integrity is uncompromised. However, due to their brittleness, cast iron is more commonly recycled than reused.
- Recycling: Cast iron is readily recyclable. Scrap yards and recycling centers accept cast iron, where it is sorted, cleaned, and melted down for new products. Recycling cast iron conserves significant energy compared to producing new iron from ore.
316 & 304 Grade Stainless Steel
- Reusability: Stainless steel drains are highly durable and resistant to corrosion, making them excellent candidates for reuse if undamaged.
- Recycling: Stainless steel is 100% recyclable and can be recycled indefinitely without loss of quality. The recycling process includes collection, sorting by grade, cleaning, shredding, melting, purification, and solidification into new products. Both 316 and 304 grades are valuable due to their alloy content, and recycling them reduces landfill waste and conserves resources.
- Preparation: Remove any non-metal attachments (e.g., gaskets, plastic parts) before recycling to ensure material purity and maximize value.
Aluminium
- Reusability: Aluminium drains are lightweight and corrosion-resistant, making them suitable for reuse in new installations if their condition allows.
- Recycling: Aluminium recycling is highly efficient and well-established. The process involves collection, sorting, cleaning, melting, and casting into new products. Recycling aluminium saves up to 95% of the energy required to produce new aluminium from bauxite ore. Collection rates for aluminium in the construction sector are extremely high, often exceeding 99% in developed markets.
- Economic Value: The high scrap value of aluminium incentivizes recycling, and the process is mature and widely available.
PVC Plastic
- Reusability: PVC drains can sometimes be reused if they are undamaged and meet current building standards, though this is less common than with metals due to wear and aging.
- Recycling: PVC is recyclable, but the process is more complex than for metals due to the material’s chemical composition and potential contamination. Mechanical recycling involves shredding, cleaning, and reprocessing into pellets or sheets for use in new products. Chemical recycling can handle contaminated or complex PVC waste by breaking it down into its basic components.
- Limitations: Recycled PVC is often used in non-critical applications due to potential contamination and degradation during use. Proper cleaning and separation from other materials are essential to ensure quality.
Best Practices for Reuse and Recycling
General Steps:
- Assessment: Inspect drains for structural integrity and contamination. Reuse is preferable when components are undamaged and meet current standards.
- Separation: Store different material types separately to facilitate recycling and prevent contamination.
- Cleaning: Remove non-recyclable attachments (e.g., rubber seals, adhesives) to improve recycling efficiency and product quality.
- Collection: Work with certified scrap dealers or recycling centers that accept construction metals and plastics. Many centers offer pick-up services for bulk materials.
On-Site Waste Management:
- Store off-cuts and surplus material for reuse on the same or future projects.
- Return oversupply to suppliers or donate to community projects to minimize waste.
- Keep metal, plastic, and concrete waste in separate bins to streamline recycling.
Environmental and Economic Benefits
- Energy Savings: Recycling metals (especially aluminium and stainless steel) saves significant energy compared to producing new materials from raw resources.
- Waste Reduction: Diverting construction materials from landfill conserves space and reduces environmental impact.
- Economic Value: Scrap metals have high resale value, and recycling supports local economies by creating jobs in collection, processing, and manufacturing.
- Sustainability: Reusing and recycling construction materials supports circular economy principles and helps meet sustainability goals in the building sector.

Conclusion
SPS and Metabronze roof and floor drains made from bronze, cast iron, stainless steel, aluminium, and PVC plastic all have significant potential for reuse and recycling. Metals, in particular, are highly valued in recycling markets, helping to save considerable energy and resources. PVC, although recyclable, needs careful handling and may be better suited for non-critical applications after recycling. Proper separation, cleaning, and working with certified recyclers are essential to maximising the environmental benefits of these materials at the end of their service life.
