BAMBOO BOTTLE

Clients Goal and assessment

It’s no secret that plastic bottles are a major environmental hazard, and while they can be relatively easily recycled, it still would be better if we used less of them. There are already better alternatives, such as glass or metal reusable bottles, but because we are creatures of convenience, we are still craving disposable options.

Globally, 80 billion plastic bottles are produced annually, of which 80 per cent end up in oceans and landfills. These bottles slowly fall apart, forming micro-plastics, which are often mistaken for food by animals, eventually ending up on our plate.

The Bamboo Bottle is made from a biodegradable pulp mixture of wheat straw, bamboo, husks, sugar cane, and/or bulrush. The shape is completely customisable.

Unfortunately, the bottle is not biodegradable in its entirety; a barrier inside is made from recycled resin. However, the two materials can be separated easily so the outside can decompose, while the inside is recycled.

 

The aim is to use less and less resin in the future, with the next generation of bottles using 40-60 per cent less resin than a standard plastic bottle and the one after that 99 per cent less. The ultimate achievement for Bamboo Water Bottle is to be “backyard compostable”.

Clients Alternative I

type of biodegradable plastic derived from biological substances rather than petroleum.

1. Biodegradable

The bottle can biodegrade within 90 days, in accordance with the DIN13432 standard.

The packaging needs a favourable environment with heat (ideally 55-60°C), mould and bacteria in order to biodegrade. This can also happen slowly in nature – we estimate that it may take around 5 years, depending on the environmental conditions. In contrast, a PET bottle takes several decades.

 

2. Biodegrading in an unfavourable environment

As explained in point 1, the bottle cannot biodegrade without a favourable environment. In a natural environment, it may occur over several years.

 

3. Bottle end of life

Biocomposites can be recycled mechanically, chemically or by remoulding. They are normally sorted in the plastic recycling bin.

 

4. How much CO2 can I save with PLA bottles?

Depending on the application, CO2 emissions can be reduced by 20% to 65%. Actual CO2 savings include those from material production, raw material processing, transport, use and destruction.

 

5. Instructions for use

Do not expose the packaging to temperatures over 60°C as the material will slowly start to lose its shape. Do not fill with hot liquids.

 

6. GM-free

As this material has been processed and polymerised, it is inert and no longer contains any GM maize genes or presents the risk of GM maize in its natural state.

The material contains no genetically modified organisms that could contaminate the environment or alter other living organisms, meaning there is no risk of spreading GM organisms when the product biodegrades or composts.

Clients Alternative II (exp)

Many of the world’s plastic bottles end up in landfills or in oceans where they takes hundreds of years to biodegrade. In response to this problem, StarckGate contacted a scientist who  has developed a biodegradable plastic bottle made of algae. When filled, the bottle remains in its solid form. As soon as it is empty however, it begins to biodegrade!

His biobased plastic bottle is made out of agar, a gel-like material used widely in food preparation as well as a growth medium is microbiological research. which comes from the cell walls of red algae. These cells have a double walled structure. The outer wall comprises polysaccharides, namely agaropectin and agarose, which are long chains of sugar molecules.  When combined with water, these algae cell walls forming the basis of agar turn into a moldable gel that can be shaped into a bottle.

When liquid is emptied, out of the bottle, the sugar molecules dry out and begin to fall apart, or rather biodegrade.

As an added bonus, this algae based bottle is completely non-toxic, so it can even be eaten. Although its creator admits that so far, the taste isn’t exactly great.

But don’t go looking for this algae bottle on supermarket shelves just yet as the long term shelf life of this material is unknown so further studies are needed. Nevertheless, it is a fascinating material exploration showing the way forward!
