NPB-PLA™ Bottle Material
NPB-PLA™ is the material behind Not A PET Bottle — a PLA-based bottle material derived from renewable corn and sugarcane biomass.
We developed NPB-PLA™ to bring a different material approach to bottled water: replacing conventional PET with a plant-based polymer while maintaining the clarity, strength and functionality expected from modern water packaging.
Not petroleum. Not PET. A different material story.
A Material Built Around a Different Starting Point
[WHAT IS NPB-PLA™?]
Conventional PET begins with fossil-based feedstocks.
NPB-PLA™ begins with renewable plant biomass.
Corn and sugarcane provide the feedstock used to produce the PLA polymer that forms our bottle material. The result is a plant-based packaging material developed specifically for water applications.
The distinction is simple:
PET starts with petroleum.
NPB-PLA™ starts with plants.
Three key points
Plant-based feedstock
Derived from renewable corn and sugarcane biomass.
0% PET
NPB-PLA™ contains no conventional PET polymer.
Designed for water packaging
The material is processed into clear, functional bottles for packaged water.
[NPB-PLA™ BY THE NUMBERS]
The Material, By the Numbers.
Derived entirely from renewable corn and sugarcane biomass.
Current product claim for return to soil through commercial/industrial composting.
No conventional PET polymer in NPB-PLA™.
Lower cradle-to-gate CO₂ emissions compared with conventional PET production, according to the current material data.
These numbers describe the material system used by NPB-PLA™. They should always be interpreted alongside the relevant processing, collection and end-of-life conditions.
Engineered for the Bottle
[MATERIAL PROPERTIES]
NPB-PLA™ isn't simply selected because it comes from renewable feedstock.
A water bottle still needs to perform.
The material is processed to provide the clarity, strength and thermal characteristics required for its intended packaging application.

These values describe the material characteristics presented for NPB-PLA™. Actual bottle performance can also depend on bottle geometry, wall thickness, processing conditions, closure system and application.
[FROM PLANT TO BOTTLE]
From the ground
to the ground.
Corn and sugarcane absorb CO₂ as they grow. The carbon is locked into the plant.
Plant sugars are fermented into lactic acid by naturally occurring micro-organisms.
Lactic acid is polymerised into polylactic acid — PLA — a clear, strong bioplastic.
PLA is moulded into our bottles. Same clarity as PET. None of the consequences.
After use, PLA is collected and industrially composted — back to soil in 12 weeks.
NPB-PLA™ follows a material pathway that begins with renewable biomass and ends with an intended industrial composting pathway.
Why PLA for Water Packaging?
[WHY WE CHOSE PLA]
Choosing a bottle material isn't only about how it looks on a shelf.
It starts much earlier — with the material's origin, how it is produced, how it performs during use and what happens after the bottle is discarded.
We chose PLA because it gives us a way to approach these questions differently.
Renewable Feedstock
NPB-PLA™ is derived from plant-based biomass rather than conventional petroleum feedstocks.
Bottle Performance
The material can be processed into clear packaging with the physical characteristics required for its intended water-bottle application.
PET Alternative
NPB-PLA™ provides an alternative material pathway to conventional PET water bottles.
End-of-Life Pathway
The material is designed around industrial composting where suitable infrastructure is available.
The goal isn’t to make a bottle that looks different.
It’s to rethink what the bottle is made from.

PET has become one of the dominant materials for bottled water because it is lightweight, clear and durable.
NPB-PLA™ approaches the bottle from a different material starting point.

Not All “Plant-Based” Claims Mean the Same Thing.
[WHAT MAKES NPB-PLA™ DIFFERENT?]
“Plant-based,” “bioplastic,” “biodegradable” and “compostable” are related terms, but they describe different characteristics. NPB-PLA™ is a PLA-based material derived from renewable plant feedstocks. Its intended end-of-life pathway is industrial composting, where appropriate infrastructure exists.
That distinction matters.
Plant-Based
Describes the origin of the feedstock.
PLA
Describes the polymer/material.
Biodegradable
Describes the ability of a material to break down under specified biological conditions.
Compostable
Describes a material/product designed to break down under defined composting conditions and standards.
Designed With the End in Mind.
[NPB-PLA™ AND END OF LIFE]
The material story doesn't end when the water is consumed.
NPB-PLA™ is designed for an industrial composting pathway where appropriate collection and processing infrastructure exists.
Under the current material specification, the claimed industrial biodegradation period is 12 weeks.
But infrastructure matters.
Industrial compostability is not the same as:
- throwing a bottle on the ground
- putting it in a normal household compost bin
- assuming it will disappear in any environment
- placing it into a conventional PET recycling stream
The correct collection and processing pathway matters.
A Material Designed for Modern Water Packaging
[NPB-PLA™ FOR WATER BRANDS]
The material story doesn't end when the water is consumed.
NPB-PLA™ is designed for an industrial composting pathway where appropriate collection and processing infrastructure exists.
Under the current material specification, the claimed industrial biodegradation period is 12 weeks.
For water brands, the bottle isn’t just a container.
It is part of the product.
NPB-PLA™ gives businesses an alternative material option for:
- packaged drinking water
- natural mineral water
- hospitality
- restaurants and cafés
- corporate water
- events
- retail bottled water
[MATERIAL SOURCING]
From Renewable Biomass to Bottle Material
NPB-PLA™ uses corn and sugarcane biomass as its stated renewable feedstock. The material journey connects:
Renewable biomass →
Plant sugars →
Lactic acid →
PLA →
Bottle
The choice of feedstock is an important part of the NPB-PLA™ material story because the material begins with renewable biological resources rather than conventional petroleum-based feedstocks.
