Eco-friendly packaging is no longer a “nice extra” in the events and catering sector. Customers increasingly expect sustainable options, councils are tightening waste policies, and many venues now prefer traders who use compostable or recyclable materials as standard.

For vendors serving slush, ice cream, and cold drinks, the cup you choose is not just about sustainability. It affects product quality, service speed, leakage risk, and how professional your stall looks in the customer’s hand. A cup that sweats too heavily, softens, or warps can slow service and damage the perceived value of what you’re selling, even if the product itself is great.

The challenge is that 2025 and 2026 bring more choice than ever. Different materials behave differently with slush, melting ice cream, and condensation. Some stay rigid all day. Others struggle in warm tents, humid mornings, or under stacked storage.

This guide breaks down the most suitable eco friendly cup types for slush, ice cream, and cold drinks, plus practical buying and handling tips so you can choose what actually works in real event conditions.

Why eco-friendly cups matter for concession businesses

Cup choice impacts much more than sustainability messaging. It influences presentation, workflow, and customer confidence. In fast-paced environments, small packaging failures quickly become expensive.

Customer expectations

More customers now actively notice packaging. Even where certain plastics are still allowed, many customers feel more positive when they see compostable or recyclable options. Eco-friendly cups can also support slightly higher pricing, because the product feels more thoughtfully presented.

Council and venue restrictions

Some events now have packaging policies written into trader agreements. Others will check on the day, particularly at larger festivals, council-run markets, and family venues. Choosing compliant cups reduces the risk of being asked to change packaging mid-event, which is one of the fastest ways to lose time and money.

Brand image and presentation

Eco-friendly cups often make your stall look cleaner and more modern. Even without heavy branding, the right cup material can signal “premium”, while flimsy packaging can do the opposite.

Practical performance

Slush and ice cream are harsh on packaging because they create moisture, condensation, and weight. The right cup reduces sweating, leaking, softening, and collapse, which keeps service fast and protects customer experience.

Eco-friendly cup selection is a practical decision as much as an environmental one.

Understanding eco-friendly cup materials

Eco-friendly cups generally fall into a few core categories. Each has strengths and limitations, and performance depends on what you’re serving and where you’re serving it.

PLA bioplastic cups

PLA, or polylactic acid, is a plant-based bioplastic. It has become popular for cold drinks and slush because it looks similar to traditional clear plastic and holds its shape well.

PLA cups work particularly well when presentation matters. Colourful slush and layered iced drinks sell faster in clear cups, and PLA helps you keep that visual appeal while improving sustainability messaging.

PLA strengths include strong clarity, good rigidity for cold drinks, and compostability under industrial conditions. The key drawback is heat sensitivity. PLA can soften or warp if it’s stored near heat sources or left in direct sun, which can happen easily at events.

PLA performs best when you treat storage as part of the system. Keep it cool, shaded, and away from warm equipment.

Paper Cups with Plant Based Lining

Paper cups with a plant-based lining are widely used for ice cream and desserts because they hold weight well and feel comfortable in the hand.

These cups are typically chosen for practicality. Ice cream cups need structure more than they need transparency, and paper handles that well. They also feel premium and clean, especially for families and longer eating times.

Paper cups can soften if exposed to heavy condensation for long periods, particularly in humid conditions. For fast ice cream service they usually perform well, but for slush they can be more variable depending on weather and how long customers hold the drink.

Paper cups are often slightly more expensive than basic plastics, but they work well where strength and customer comfort matter most.

Bagasse cups

Bagasse is made from sugarcane fibre. It is one of the sturdier compostable options and often feels more rigid than paper in damp conditions.

Bagasse performs exceptionally well for ice cream because it handles moisture and weight reliably. It also holds up well for thick or premium servings, where customers are holding the cup longer and the product is melting gradually.

The downside is that bagasse is not transparent and can feel heavier than other options. For large drink sizes, it can feel like overkill. Bagasse is usually best used where structural strength is the priority rather than visual presentation.

Recyclable PET cups

PET is still plastic, but it is widely accepted in UK recycling streams and remains one of the most common choices for cold drinks and slush because it is strong, clear, affordable, and easy to source in bulk.

Many eco-aware traders still choose PET because it performs consistently in real event conditions. It handles condensation well, stacks cleanly, and stays rigid during fast service.

The main drawback is perception. Some customers see any plastic as “less eco”, even if it is recyclable. PET also relies on correct disposal. If the waste stream is poor, the recycling benefit is reduced.

PET is best described as the practical recycling-led option, especially for high-volume slush.

Choosing cups for slush

Slush is one of the toughest products for cups. It is cold, wet, and often served quickly in high volume. The cup needs to stay rigid under pressure, resist condensation, and feel stable in the customer’s hand.

Slush also sells heavily on visuals. Clear cups help because colour drives impulse purchases.

For most traders, the most reliable eco-friendly routes for slush are recyclable PET and PLA. Both tolerate condensation far better than paper-based options and maintain the clear presentation that helps sell slush from a distance.

Paper cups can work for slush, but they are less predictable in warm or humid conditions because sweating can soften the outer surface over time. If you want speed, reliability, and minimal issues during rush periods, PET and PLA tend to outperform paper.

Choosing cups for ice cream

Ice cream has different demands. Weight and melt control matter more than transparency.

A good ice cream cup should hold structure with dense scoops, stay comfortable in the hand, and resist softening as the product melts. This is where paper cups with plant-based lining and bagasse cups usually perform best.

Bagasse is especially strong for premium or larger servings, because it stays rigid and handles moisture well. Paper cups work well across most everyday ice cream service, particularly if you use quality lined cups designed for commercial use.

For ice cream, strength and comfort are the winning priorities, and both bagasse and lined paper deliver that reliably.

Choosing cups for cold drinks

Cold drinks sit somewhere between slush and ice cream. Condensation is still a major factor, especially with iced coffees, lemonades, and drinks served with lots of ice.

For most cold drinks, PET and PLA perform extremely well because they resist sweating and hold shape over time. They also support the best presentation for drinks where colour, layers, or fruit garnishes help conversion.

Paper cups can still be useful for non-carbonated drinks, but they can soften if drinks sit for longer periods, and they do not give the same visual effect. For fizzy drinks, strength matters more because carbonation adds pressure, and PET tends to be the most reliable option in that category.

The simplest approach is to use clear PET or PLA for the majority of cold drinks, and reserve paper cups for specific still drinks where transparency is not needed.

Cost considerations for 2025/2026

Eco-friendly packaging pricing varies with material, supply availability, and bulk purchasing.

PET typically remains the most affordable option for high-volume drink sales, which is why it continues to dominate slush trading. PLA often costs more per unit than PET, but supports stronger sustainability messaging and maintains clear presentation. Bagasse and quality lined paper cups can also cost more, but they often justify themselves through better performance and fewer failures during service.

It is also worth thinking about the indirect cost. Cup failures create waste, slow queues, and reduce customer confidence. A slightly higher unit cost can be worth it if it avoids softening, leaks, or collapse during busy periods.

Some venues with composting facilities may also encourage fully compostable packaging, and in a few cases that can influence trader acceptance or waste handling expectations.

Storage and handling tips to prevent damage

Eco-friendly cups often need better storage habits than traditional plastics, especially in unpredictable event weather.

Keep cups cool, dry, and shaded wherever possible. Avoid storing them near machinery that produces heat, and avoid leaving boxes near tent edges where sunlight can warm stock quickly. Prevent over-stacking, because pressure can deform rims and lids, especially with PLA. Keep cups raised off the ground to avoid moisture transfer, and rotate stock so cartons are not exposed to humidity for extended periods.

A practical approach is to refill your service zone in smaller batches. That way, the bulk of your stock stays protected while the working area stays efficient.

Matching the right cup to your product line-up

For many vendors, the most reliable approach is not using one cup material for everything. Different products behave differently, and mixing materials often gives the best balance of performance and sustainability.

For Slush, recyclable PET or PLA usually performs best because both handle moisture well and maintain clarity. For ice cream, bagasse or lined paper cups give strength and comfort. For cold drinks, PET or PLA suits most cases, while paper cups can still work for still drinks where presentation is less visual.

This mixed approach keeps service smooth, improves presentation, and reduces waste without forcing you into a one-size solution that may not perform well across your whole menu.

Final thoughts

Choosing eco-friendly cups for slush, ice cream, and cold drinks in 2025/2026 comes down to performance as much as sustainability. The right cup protects presentation, keeps service fast, and prevents waste caused by softening, sweating, or collapse.

If you build your setup around a practical mix of recyclable PET, compostable PLA, sturdy bagasse, and lined paper cups, you can create a packaging system that feels modern, meets venue expectations, and performs reliably across real event conditions.

Frequently Asked Questions (FAQ)

What is the best eco-friendly cup for slush drinks?

For most traders, recyclable PET and compostable PLA are the strongest choices because they handle condensation well, stay rigid, and keep the clear presentation that helps sell slush.

Are PLA cups suitable for outdoor events?

Yes, but storage matters. PLA can warp if exposed to heat or direct sunlight, so keep it shaded and away from warm equipment to maintain cup shape and rim strength.

What is the best compostable cup option for ice cream?

Bagasse and paper cups with plant-based lining are both strong options. Bagasse is especially sturdy for premium servings, while lined paper cups work well for standard scoops and fast service.

Are paper cups good for slush?

Paper cups can work, but they are less reliable for slush because condensation can soften the cup over time, especially in warm or humid conditions. Clear PET or PLA usually performs better.

Is recyclable PET considered eco-friendly in the UK?

PET is widely recyclable across the UK, which makes it a common choice for eco-aware traders who prioritise recycling streams. It is not compostable, but it can still fit sustainability goals when disposed of correctly.

What cups are best for fizzy cold drinks?

Fizzy drinks put pressure on cups, so strength matters. PET is typically the most reliable option for carbonated drinks due to its rigidity and consistent performance.

Do eco-friendly cups cost more than standard plastic cups?

Often yes. PLA, bagasse, and quality lined paper cups can cost more per unit than traditional plastics. However, better performance and improved customer perception can offset the difference.

How should I store eco-friendly cups at events?

Store cups in a cool, dry, shaded area. Keep them off the ground, avoid over-stacking, and refill service areas in smaller batches to protect stock from heat and humidity.

Can I mix cup types across my menu?

Yes, and it is often the best approach. Use PET or PLA for slush and cold drinks, and use bagasse or lined paper cups for ice cream where strength is more important than transparency.

Do compostable cups always compost at events?

Not always. Compostable cups usually require industrial composting facilities. If events do not provide proper composting streams, compostables may end up in general waste, which reduces the benefit.
