Is paper‑pack water better for the environment than aluminum cans?

Yes. LCA shows our paper‑pack water emits about 59% less CO₂ than aluminum cans of the same volume.

Why are Havary’s cartons eco‑friendly?

They use FSC‑certified paper and plant‑based plastics, cutting CO₂ significantly. In addition, our closed‑loop recycling program further reduces impact.

Do Havary’s cartons contain plastic?

Yes—plant‑based polyethylene (from sugarcane) is used for the cap and barrier layers to ensure safety and shelf life while lowering fossil‑based plastic use.

How much waste volume can paper‑pack water reduce?

Over 78% volume reduction vs. PET or aluminum after flattening the empty pack, which saves bin space and improves waste handling efficiency.

What are the caps made of?

Plant‑based polyethylene (bio‑PE) derived from sugarcane.

Is aluminum used in the cartons?

Our cartons are paper‑based (FSC) with functional barrier layers. We avoid conventional aluminum layers used in many beverage packs.
