Using leftover wood, scientists have made a durable biodegradable product similar in properties to plastic.
In a new work, the authors described the process of deconstruction of a porous matrix of natural wood, they turned it into a suspension.
The author claims that the resulting material has high mechanical strength, stability, and also retains liquid. It can also decompose or be recycled. It also has almost no environmental impact compared to plastics.
To create the mixture, the researchers used wood powder, which is waste from sawmills. They then deconstructed the loose porous structure of the powder using a biodegradable and recyclable deep eutectic solvent (DES). The resulting mixture has a high viscosity, it can be cast without destruction.
Next, scientists tried to process the resulting material: the sheets of bioplastic were decomposed into the soil after two weeks and completely collapsed after three months. Also bioplastic can be turned back into a slurry.
