Zero.Refill Program

At Kahuku Natural Zero Waste is really important to us. 

We believe there is no easy solution to packaging, everything has a trade off, whether it be a higher upfront carbon footprint for a longer life cycle and lower overall footprint, or a lower upfront footprint with shorter life, and non biodegradable or reusable end life.

We have chosen a higher upfront, long life cycle, and 100% reusable option using stainless steel.

Stainless Steel is North America's number 1 recycled material. It is 100% recyclable.  In fact, the average steel produced contains more than 60% recycled content already!

Stainless Steel is unfortunately energy intensive to produce. 

The energy cost is reduced significantly when you consider stainless steel uses far more recycled content. 

Even after stainless steel is scratched it can still be used unlike aluminium. Aluminium bottles needs to be lined to avoid leaching.

It is lighter than glass, so transportation is less.

Stainless Steel can be recycled and used over and over without losing any of it's quality.   It is 100% recyclable.  So while the initial footprint is bigger, you can use a stainless steel bottle in excess of 500 times - without doubt the best choice for the planet.

1 stainless steel bottle = approx 50 bottles in energy consumption manufacturing

1 stainless steel bottle can be reused in excess of 500 times.  Therefore one of our 1L refill bottles is going to eliminate over 1,000 plastic cleaner or shower soap bottles.

Stainless steel has a 92% actual recycling rate - the highest of any option, with a possibility of 100% - again by far the highest.

So while there is no doubt the upfront foot print in manufacturing steel is higher than other materials, the life cycle cost and end of life impact far outweighs any other option.

With our bottles you are effectively buying a "forever" bottle, and once you replace all your plastic and glass bottles, you will never buy another bottle again.








Infinitely Recyclable & Reusable

Infinitely Recyclable/Reusable however often downcycled into roading aggregate or landfilled due to recycling system limitations and contamination

Can only be down cycled approx 7 times before can no longer be recycled or used and becomes landfill



Energy Intensive to produce

Energy Intensive to produce

Less energy intensive to produce but uses finite petroleum resources



Reasonably light to transport

3x weight of stainless steel to transport

Lightest material to transport



An average stainless steel object is composed of about 60% recycled material. Approximately 90% of end-of-life stainless steel is collected and recycled into new products

Whilst very recyclable, only approximately 25% of glass is actually recycled

Approximately 91% of all plastic made, has never been recycled. End of life ultimately most plastic ends up in landfill



Non toxic if ends up in landfill. Can always be recycled. Won’t end up in tiny pieces inside animals

Non toxic if ends up in landfill. Can still possibly be recycled. Is very hazardous to humans and animals when broken

PET will never decompose. Becomes toxic in landfill. Breaks into tiny micro plastic which ends up in soil, inside animals and sea life



Won’t ever break if dropped during transportation

Will break if dropped, and very fragile to transport requiring more packaging

Doesn’t break when dropped but may still split or lose structural integrity
