Researchers at Northeast Forestry University have engineered a high-performance, fully biodegradable bioplastic made entirely from bamboo cellulose.
The newly developed material, designated as bamboo molecular plastic or BM-plastic, successfully resolves a longstanding limitation of organic-based biomass plastics by matching or outperforming standard petroleum-based polymers in mechanical strength and thermal resilience.
Led by Dawei Zhao and Haipeng Yu, the scientific team used molecular engineering to construct the bioplastic through an eco-friendly, two-step process.
Deep eutectic solvents are first applied to dissolve the hydrogen-bond network of the bamboo down to a molecular level, followed by an ethanol solvent treatment that reorganises the cellulose molecules into a dense, chemically modified network.
Laboratory tests verified that the resulting material achieves a tensile strength of 110 megapascals, roughly double that of common engineering plastics like polylactic acid (PLA) and high-impact polystyrene, and can withstand extreme environmental conditions from minus 30 Celcius to 100 Celsius without warping or cracking.
Because the bamboo plastic retains up to 180 Celcius of thermal stability, researchers have positioned the material as a commercially viable substitute for rigorous industrial applications, including automotive components, electronics housings, and household appliances.
The bioplastic requires no specialised manufacturing equipment and remains compatible with existing industrial pipelines through injection moulding, compression moulding, and standard machining.
In contrast to conventional plastics that persist in landfills and ecosystems for centuries, this bamboo-derived alternative completely decomposes in natural soil within 50 days without leaving behind microplastic residues.
In addition, the material supports true circular economy systems; it can be closed-loop recycled multiple times while retaining up to 90 per cent of its original structural rigidity and strength.
As bamboo has a rapid growth cycle and produces up to five times more biomass than traditional timber, the feedstock offers a highly renewable, localised resource that does not compete with global food crops.
