Can plastic be made from bamboo?
The petrochemical plastics are causing severe environmental crises. To overcome these challenges, the scientific world has developed a sustainable alternative to traditional plastics through bamboo molecular plastics (BM-plastics). In comparison to starch-based bioplastics derived from food crops, BM-plastics exhibit greater mechanical strength and thermal stability. Researchers from the Northeast Forestry University, China, have made this valuable discovery.
More than just a versatile plant, bamboo rises as a powerful social capital and also a sustainable resource. It weaves its magic through communities, offering livelihoods to farmers and artisans, its strength reflected in traditional crafts and towering buildings. The major limitations of bioplastics, such as inadequate mechanical strength, thermal stability, and processability are overcome by a molecular engineering strategy to fabricate high-strength bamboo molecular plastics (BM-plastics) through a solvent-regulated shaping process. The major challenges of this innovative strategy are breaking of bamboo cellulose hydrogen bonds. It is achieved through a solvent-mediated molecular engineering strategy to fabricate high-performance Bamboo Molecular plastics (BM-plastics) with tunable H-bond networks. Employing a hydrated ZnCl₂/formic acid deep eutectic solvent (DES) can disassemble the native H-bond matrix of bamboo cellulose into a homogeneous molecular system. Thereafter, subsequent ethanol stimulation triggers the rearrangement of cellulose chains, promoting dense, ordered H-bond interactions. Through this process can achieve a bioplastic with exceptional mechanical strength, thermal stability (>180 °C), and versatile processability via injection, moulding, and machining techniques. The BM plastics are reusable and also maintain full biodegradability in soil within 50 days shows making it more valuable for mitigating plastic pollution. This discovery not only presents bamboo as a sustainable raw material for next-generation bioplastics but also provides a viable pathway to mitigate global plastic pollution.

Bioplastics derived from biomass show promise as sustainable alternatives to petrochemical plastics, but their adoption is hindered by their inferior mechanical properties and processability. Here, the authors report a deep eutectic solvent treatment process which yields bamboo plastics with high me...
