RIKEN develops fully ecologically degradable plastic with potential for industrial versatility
The material is formed using "cross-linked salt bridges"—a chemical structure that dissolves upon exposure to saltwater or soil. Once these bridges break, the plastic disintegrates into its chemical components, which can be completely metabolized by bacteria.
The RIKEN Center for Emergent Matter Science (CEMS), a research institution specializing in environmentally sustainable technologies, has announced a groundbreaking advancement in biodegradable plastics. Seeking to address the issue of microplastic pollution, the team has developed a plastic with fully soil- and ocean-degradable properties.
The material is formed using "cross-linked salt bridges"—a chemical structure that dissolves upon exposure to saltwater or soil. Once these bridges break, the plastic disintegrates into its chemical components, which can be completely metabolized by bacteria.
The plastic’s utility extends to a wide range of applications, including rigid hard plastics and low-tensile flexible materials, making it potentially suitable for diverse industries.
Beyond its primary uses, the material provides additional environmental benefits. After degradation, it releases phosphorus and nitrogen into the soil, functioning as a natural fertilizer.
In addition, the plastic exhibits impressive recyclability. Experiments have shown that after dissolving the material in saltwater, a significant portion of its key components can be efficiently reclaimed as powders, ready for conversion into ocean-degradable plastics again.
