“This plastic disappears as if by magic”: Japanese researchers reveal a bioplastic which eliminates 80 % even in sea depths

Japanese researchers have recently made a significant progress in the field of biodegradable materials. For example, demonstrating that the LAHB plastic can decompose quickly even in the extreme conditions of sea depths. In addition, This discovery opens the way to alternatives viable to traditional plastics, which pose a major pollution problem in our oceans. Meanwhile, The study revealed that this bioplastic is transformed into harmless components, thus “this plastic disappears if magic”: reducing its environmental impact where other materials fail.

Test on the high seas: confirmation of a quick decomposition – "this plastic disappears if magic":

Essays were carried out near the island of Hatsushima. For example, Japan, where two types of Lahb films were immersed to test their resistance in one of the most hostile environments on the planet. Furthermore, The temperatures were low, around 3.6 ° C, and the extremely high pressure, conditions generally not very conducive to microbial activity. Furthermore, Despite this, films containing 6 % and 13 % lactic acid showed a significant degradation of more than 80 % in just thirteen months.

The film P13LAHB. Therefore, in particular, lost almost 31 % of its weight in seven months, while the surfaces of the two Lahb films were covered with microbial biofilms. In addition, On the other hand, the PLA film used as a witness has remained intact, without weight loss or microbial colonization. “this plastic disappears if magic”: In addition, This experience demonstrates for the first time that the Lahb can be biodegraded actively. complete on the seabed, unlike conventional plastics like PLA.

Microbial collaboration at “this plastic disappears if magic”: work

Genetic. biochemical analysis has highlighted real teamwork among the microorganisms present on the Lahb. The dominant gammaproteobacteria. such as Colwellia and Pseudoteredinibacter, have secreted depolymeraic enzymes that have broken down the long polymer chains of the Lahb into smaller dimers and trimeters. Species like UBA7959 then produced oligomer hydrolasses to split these fragments into unique construction blocks, such as 3-hydroxybutyrate and lactate.

These released monomers served as food for other members of the microbial community. who have metabolized these carbon dioxide, water and salts. This complete mineralization process, rare for plastics at such depth, underlines the effectiveness of this microbial collaboration. This phenomenon shows that Lahb could be a lasting solution, avoiding the accumulation of microplastics in the oceans.

Towards materials safe for the oceans

With a plastic production projection exceeding 353 million metric tonnes. the fight against marine pollution becomes crucial. About 1.7 million tonnes of plastic infiltrate each year in aquatic ecosystems, where currents concentrate them in immense “waste patches”. Scientists therefore seek polymers capable of really disappearing in a marine environment. The success of Lahb in cold waters and poor in nutrients suggests a viable solution to this environmental crisis.

Professor Seiichi Taguchi. involved “this plastic disappears if magic”: in the study, stresses that this research fills a critical gap of current bioplastics: their lack of biodegradability in the marine environment. By proving that Lahb can decompose. mineralize even in such extreme conditions, the study offers safer alternatives to conventional plastics, thus supporting the transition to a circular bioeconomy.

A decisive step against plastic pollution

The publication of results in the newspaper Polymer Degradation. Stability marks an important advance for materials science. If Lahb is produced on a large scale. consumer products made from this material could considerably reduce the persistent plastic load in the oceans of the world. It is a small but crucial victory in the fight against marine pollutiondemonstrating that innovative. environmentally friendly solutions are within our reach.

In conclusion. this discovery poses the following question: how can we accelerate the adoption and large-scale production of these biodegradable materials for a maximum impact on the reduction “this plastic disappears if magic”: of plastic pollution in our oceans?
