There are several options to make use of NaKu products at the end of their life cycle. Natural polymer is biodegradable. This means that it is compostable in accordance to the DIN standard EN 13432 and therefore fulfills the requirement to degrade to biogenic material within 90 days. Natural polymer is also combustible and recyclable; this means we can reuse it for the manufacturing of other products.
All materials used in manufacturing and therefore all products made by NaKu are biodegradable. This means that natural polymers decompose completely to form organic basic substances like H2O, CO2 and biomass. The amount of time for its decomposition mainly depends on the wall thickness of the biopolymer and the composting conditions (i.e., heat, humidity, bacteria, fungi).
As an example, let’s take a closer look at the NaKu fresh-storage-bag: Industrial composting plants hold the perfect conditions for rotting. The temperature is maintained at 60 degrees. A lot of bacteria that are able to decompose organic material such as biodegradable polymers are also present. The compost is also circulated periodically. Under these conditions, it takes a NaKu bag about 3 to 5 days to decompose.
In an agricultural compost heap that is regularly intermixed the composting of a NaKu bag takes about 9 to 12 weeks in warm weather.
Even a biodegradable NaKu bag should not be thrown away carelessly. If a NaKu bag happens to remain lying on the roadside or in the woods, nature needs to rely on itself. It will still only take about one year for a NaKu bag to be degraded under wind, sunshine, rain and natural bacteria. Of course this is not ideal, but far better still than what would occur with conventional plastics. Conventional plastic is neither biodegradable nor does it fully decompose on its own. It takes several decades for it to start to break down into smaller pieces. But the problem is still there – we just can’t see it anymore. If this plastic gets into the sea, fish or seabirds will think it is plankton and eat it. They then die with a proverbially full stomach.
Still, our biodegradable fresh-storage bags should not be carelessly thrown away!
