How to recycle

Denim insulation is a strong sustainable option because it repurposes post-consumer textile waste, giving discarded cotton a second life and reducing the volume sent to landfill. By using recycled fibres, it typically has a lower embodied carbon footprint than virgin materials, and cotton’s natural properties still provide effective thermal performance without relying heavily on synthetic inputs. Many denim liners can also be reused multiple times, extending their lifecycle, and where designed without complex plastic laminates, they can be recycled again or more easily processed at end of life, making them a practical, circular choice for insulated packaging.

Smoothie sachets can’t typically be made from recycled plastic because they need to meet strict food safety and barrier requirements that recycled materials often can’t guarantee. Packaging for foods must provide a highly reliable barrier against oxygen, moisture, and contamination to maintain shelf life and safety, and this is best achieved with virgin, multi-layer plastics. Recycled plastics can carry trace contaminants, have variable quality, and are harder to use in the complex laminate structures required for these sachets, which makes them unsuitable for direct food contact in this format under current regulations and manufacturing constraints.

We use dry ice instead of standard ice packs because smoothies need to stay fully frozen at around -18°C for the entire transit time, and regular ice simply can’t maintain temperatures that low for 24 hours.

Ice packs typically stabilise around 0°C, which would allow the product to thaw and compromise quality and safety. Dry ice, by contrast, sits at around -78°C and sublimates slowly, providing a consistent deep-freeze environment that keeps the smoothies solid from dispatch through to delivery.
