PP Grade 5 Plastic vs Aluminium Cups: Which Is Better for Your Venue and the Planet?

When venues explore reusable cups, two materials usually rise to the top: PP Grade 5 plastic (polypropylene) and aluminium. Both sound “sustainable”, both can be reused, and both are recyclable – but they’re very different when you dig into cost, lifespan and environmental impact.

At Revibes, our reusable cups are made from food-grade PP5, and that’s not by accident. Here’s a clear breakdown to help you decide what’s right for your bar, stadium, festival or event.

1. What Are PP Grade 5 Cups?

PP Grade 5 (polypropylene) is a tough, lightweight plastic commonly used in reusable food containers, takeaway tubs, and dishwasher-safe products.

For reuse systems, PP5 has some big advantages:

• Durable but flexible – it can take knocks, drops and stacks without denting.

• Lightweight – lower transport emissions and easier handling onsite.

• Dishwasher-safe – handles repeated industrial washing cycles.

• Fully recyclable – when collected and processed correctly, PP can be recycled into new products (crates, components, etc.).

At Revibes, our PP5 cups are designed to be reused hundreds of times in a circular system before being recycled at end of life.

2. What About Aluminium Cups?

Aluminium cups are often marketed as “premium”, “infinitely recyclable” and “eco-friendly”. There’s some truth there:

• Very strong – aluminium is rigid and feels high-end.

• Highly recyclable – aluminium has high scrap value and can be recycled repeatedly if it’s actually collected and processed.

• Premium aesthetic – the metallic look can work well for particular brands or VIP areas.

But there’s a catch:

• Aluminium production is extremely energy-intensive, especially the primary (virgin) aluminium used in many new products.

• If the cups aren’t reused many times and then properly recycled, you get the environmental cost of aluminium without the benefit.

So the question becomes: how do they actually compare over real-world use?

3. Cost Difference: PP vs Aluminium

Exact pricing depends on design, branding and volume, but there are clear trends:

Upfront Unit Cost

• PP Grade 5 cups

  • Generally much cheaper per unit than aluminium.

  • Ideal for large-scale orders for festivals, stadiums and high-volume venues.

  • Full-colour wrap branding is usually more affordable.

• Aluminium cups

  • Often 2–4x more expensive per cup than PP reusables (sometimes more for custom runs and premium finishes).

  • Better suited to small runs, VIP bars or where the “metal” look is part of the brand story.

Operational Costs

For a reuse system, the real question is cost per use, not cost per unit.

Because PP cups are lower cost and designed for high cycle counts (e.g. ~300–400 uses in a controlled system), your cost per use is typically very low once cups are in circulation.

Aluminium cups can also be reused, but:

• Higher upfront cost means you need many more uses to reach a similar cost-per-use.

• If cups are frequently lost, taken home or damaged, the economics become much weaker.

For most high-volume venues and festivals, PP Grade 5 usually wins on cost-effectiveness, especially once you factor in losses, breakages and branding needs.

4. Lifespan & Practical Durability

PP Grade 5 Cups

• Designed for hundreds of washes in industrial dishwashers.

• Resistant to cracking and can flex on impact rather than dent.

• Stack neatly; less risk of jams or damage in crates and cup towers.

• Surface can scratch over time, but this is cosmetic – the cup still performs.

In our experience with Revibes, a PP cup in a well-run reuse system can comfortably achieve an average of around 350 reuses before being retired and recycled.

Aluminium Cups

• Very strong and rigid, but can dent if dropped or crushed.

• Dents can make cups hard to stack or unpleasant to drink from, shortening practical life.

• Coatings and inks can chip or scratch, affecting appearance.

• Heavier than PP, which can impact handling and logistics.

Lifespan for aluminium can be very good if cups are respected, not frequently dropped, and handled carefully in washing and transport. In rowdy festival or stadium environments, that’s a big “if”.

5. Environmental Impact: The Full Picture

This is where things get interesting – and where assumptions often fall apart.

A. Carbon Footprint & Production

• PP Grade 5

  • Requires less energy to produce per kilogram than aluminium.

  • Lower melting temperatures and less energy-intensive processes.

  • When a PP cup is reused hundreds of times, the production footprint is spread very thin across each use.

• Aluminium

  • Primary aluminium is highly energy-intensive, often associated with significant greenhouse gas emissions unless powered by renewables.

  • Recycled aluminium has a much lower footprint than virgin, but not all aluminium cups are made from high recycled content.

From a pure manufacturing emissions perspective, PP generally starts with a lower carbon footprint per cup.

B. Weight & Transport

• PP is lighter, which reduces emissions in shipping and local transport.

• Aluminium is heavier, especially when you move tens of thousands of units across long distances.

Over the full logistics chain – manufacturing country to warehouse to venue and back – this weight difference adds up.

C. Reuse Performance

This is where reuse systems change everything.

If a PP cup is reused around 350 times in a circular system and then recycled, the environmental impact per drink becomes incredibly low compared to single-use cups (even bioplastic or “compostable” ones).

For aluminium to compete, you need:

1. High actual reuse rates (not just the potential to reuse), and

2. Strong end-of-life recycling, with cups captured and sent into proper metal recycling streams.

In real-world settings like festivals and stadiums, cups are:

• Dropped

• Taken home as souvenirs

• Thrown into general waste

If a significant portion of aluminium cups don’t make it back into circulation or recycling, the environmental benefit is heavily reduced – but the large production impact remains.

D. End-of-Life & Recycling

• PP Grade 5

  • Widely recognised as recyclable, but requires proper collection and local recycling capacity.

  • In a controlled system (like Revibes), cups can be batch-collected and sent to specific recyclers to be turned into durable products like crates.

• Aluminium

  • Technically one of the most recyclable materials we have.

  • Holds good scrap value, which can incentivise collection.

  • Again, this only works if cups are actually returned and sorted correctly.

Both materials can have strong end-of-life outcomes. The deciding factor is whether your system genuinely returns the cups at high rates.

6. So Which Should You Choose?

PP Grade 5 Cups Are Usually Best When:

• You’re running high-volume bars, festivals, stadiums or busy venues.

• You want full-colour, wrap-around branding that looks sharp and on-brand.

• You care about a low cost-per-use and simple operations.

• You want a lower embodied carbon footprint per cup and a realistic chance of hundreds of reuses.

That’s exactly why Revibes uses PP Grade 5: it’s the best balance of durability, cost, performance and environmental impact in real-world reuse systems.

Aluminium Cups Might Make Sense When:

• You’re targeting a premium or niche experience (VIP bar, corporate gift, small run).

• You have a very controlled environment where cups are unlikely to be lost, dented or taken home.

• You’ve verified that the cups use high recycled aluminium content and will be reliably recycled at end of life.

But for the vast majority of Australian venues, festivals and stadiums, PP Grade 5 reusables will deliver better value and, in practice, a lower overall footprint.

7. How Revibes Can Help
