Teaching humanity to sort garbage, send it for recycling, or at least litter less is an extremely difficult task. But what if you just change the source material itself, because of which so many problems? To replace polymers from hydrocarbons with their analogs from biologically active substances, which, with similar performance characteristics, can safely decompose in nature?
The idea is good, but there is a huge but - the production of bioplastics is not cheap and requires resources that are needed for agriculture. Therefore, scientists from Israel drew attention to the microbes of the Haloferax mediterranei species, which feed on the Ulva lactuca algae. A byproduct of their life is a substance called polyhydroxyalkanoate, which can be used to make plastics.
The fact that you can build an entire "microbial farm" and create bioplastics on it has been proven in laboratory tests. The advantage here is that algae can be grown directly in the ocean, in any free area, without occupying useful land. Scientists are now testing which types of algae, nutritional supplements and living conditions provide the best results. And also - how to achieve that the bioplastic immediately has the desired properties and how to mix the initial components for the correct result.
