Zero.Refill Program

At Kahuku Natural Zero Waste is really important to us. 

We won't use Plastic, but why isn't glass a primary material?

Glass can be recycled endlessly by crushing, blending, and melting it together with sand and other starting materials. Doing so benefits manufacturers, the environment, and consumers. Yet each year only one-third of the roughly 10 million metric tons of glass that Americans throw away is recycled. The rest ends up in landfills. In contrast, some European countries recycle more than 90% of their waste glass.  It is important to note that not all glass is recyclable. 

Glass is almost equivalent to low weight PET plastic in it's manufacture and carbon emissions.

Glass is also difficult to transport - so easily breakable.  This means more packaging is required. Duplicate packages may be required if couriers break a package. 

And for the same reason, it's also potentially dangerous when talking soaps and cleaners. Modern bathrooms and kitchens contain hard surfaces such as tiles, concrete, hard surface counters, and more.  One slight misplacement, or a drop of the bottle ends up in product up the walls, and glass fragments everywhere. Consumer safety is paramount to us.  

These reasons are factors for us with our ethical business philosophies.

However, we understand the added cost of stainless steel and we want our products to be affordable. So we have evolved to packaging some products in glass to allow you the opportunity to choose. But please consider it carefully, where it will be used, and what the outcome might be if the bottle is dropped! 







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
