To make a positive contribution to the environment and contribute to reducing disposable plastic, we also work with ‘nature-friendly’ eco materials: biobased polyethylene made of sugarcane and biodegradable polyethylene. We’d like to explain the difference.
This bottle is made of 100% biobased material from sugarcane. The sugarcane is processed to produce molasses. Aside from sugar, this can also be made into ethylene. This is processed into ethynol products such as polyethylene. This way of making ethynol products is much cleaner than the conventional method with petroleum. In short, sugarcane produces a perfect product that is 100% recyclable, and we use it to make bottles.
This production method has a nice added benefit: as the sugarcane grows, it removes CO2 from the air. One tonne of biobased polyethylene actually takes double its own weight in CO2 out of the air. That makes it even better for our environment!
The bottle made of biodegradable polyethylene decomposes in the landfill. The flexibility of this material means it is much more recyclable. On one hand because it is simply made of polyethylene, you can dispose of this bottle in the plastics bin to be 100% recycled. On the other hand, the bottle is biodegradable.
This is achieved by adding a bio-batch to the material that changes the molecular structure of the bottle. This had no effect on the use of the bottle until it is in the landfill or is accidentally left behind during a ride through the forest. In the middle of the landfill or under a layer of leaves and soil in the forest, there is heat and humidity. At the correct temperature, the bio-batch additive activates and the bottle decomposes into water, humus and gas. It does not degrade into small pieces of plastic as in oxo-biodegradable materials. The whole composting process in a landfill takes about one to five years. In nature this takes longer. Furthermore, in the landfill the gas can be recaptured for use as an energy source.
