Development history of blended biodegradable plastics

A type of plastic material that uses natural polymers such as starch, cellulose, plant fiber, lignin, and chitin as raw materials, or adds additives through various molding processes. Experts from the University of Bath in the UK use lignin to produce new micro-particles instead of traditional plastic particles and add them to daily chemical products.

First dissolve the lignin, make the solution pass through the microporous membrane to form tiny round droplets, and then solidify to form. The resulting particles are firm enough to meet the application requirements of daily chemicals, and they are easily decomposed by microorganisms after flowing into the sewer system. Harmless carbohydrates will also degrade quickly in the natural environment. This technology is currently being developed industrially.

The University of Nottingham in the United Kingdom has developed a bioplastic film. The raw material comes from starch, cellulose or protein such as konjac flour. During the film formation process, plant carbohydrates and protein macromolecules combine to form a special network structure. The film has suitable mechanical strength and transparent appearance, low air permeability, can reduce water loss, slow down food corruption in the package, and seal the fragrance to improve Storage safety and extended shelf life, 100% biodegradable, ingestion will not harm human health, it is an ideal food packaging material.
