Basic Definition of Eco-benign Plastic

The term "eco-benign plastic" originates from the common folk's colloquial expression "self-modifying plastic," while its scientific name is "modified polyolefin biodegradable plastic."Eco-benign plastic is a masterbatch developed using nanocomposite technology, which is added to polyolefin raw materials to induce chemical modifications.This novel eco-friendly material degrades into carbon dioxide, water, and organic matter within two years under the influence of natural environmental factors such as light, heat, oxygen, water, and microorganisms.

Eco-benign plastic is a new type of degradable plastic.

Eco-benign plastic is an innovative technological solution developed to address plastic pollution at its source. After 13 years of research, it represents a groundbreaking technology that accelerates plastic degradation and reintegrates it into the ecosystem. Distinct from conventional plastics and bio-based degradable plastics, Eco-benign constitutes a novel technical approach that has evolved into a truly sustainable green material through successful practical applications. Compliant with international standards such as PAS 9017:2020, this technology demonstrates exceptional innovation and superior performance worldwide.

Eco-benign plastic has undergone full life cycle testing

From raw materials to masterbatch, from product design to standardized production processes, and from pre-use, during-use, to post-use stages - including both practical application outcomes and user feedback - the entire lifecycle of eco-benign plastic production and usage has undergone comprehensive testing. A total of 281 test reports have been generated: 40 for raw materials, all meeting national requirements for food contact plastic resins; 11 for masterbatch tests, all complying with national hygiene standards and limits for toxic/hazardous substances in food packaging polyethylene resins; and 230 tests conducted before, during, and after product degradation, all conforming to national standards and specifications.

The abiotic and biotic oxidative degradation processes of eco-benign plastics

chain initiation

The molecular bonds of polyethylene break under mechanical forces or energy stimuli such as light or heat, generating highly reactive free radicals.

chain growth

Under aerobic conditions, highly reactive free radicals rapidly react to form intermediate products such as peroxyl radicals or hydroperoxyl radicals.

chain transfer

Compounds containing unstable peroxyl radicals or hydroperoxyl radicals undergo molecular bond cleavage, yielding carbonyl-containing compounds.

chain cessation

Carbonyl-containing compounds are converted into aldehydes, carboxylic acids, esters, and other compounds via the Norrish Type I reaction; alternatively, ketone carbonyls are formed through two consecutive Norrish Type II reactions.

biodeterioration

Microorganisms secrete polymers such as polysaccharides and proteins on their cell surfaces to form a mucous layer, which helps them defend against adverse environments and aggregate minute airborne particles to facilitate their growth and reproduction. During polyethylene degradation, this mucous layer effectively reduces the hydrophobicity of the polyethylene molecular surface, enabling microbial adhesion to the material surface and promoting interaction between the extracellular enzymes secreted by microorganisms and the molecular chain segments or low-molecular-weight substances on the polyethylene surface.

biolysis

Specific enzymes secreted by microorganisms decompose polyethylene molecular segments into low molecular weight oligomers, dimers, monomers, and other molecular fragments through multiple reactions such as hydrolysis and oxidation.

Biological Assimilation

The low-molecular-weight substances generated from polyethylene decomposition penetrate the cell membrane and enter the microbial organism. Depending on the microbial species and growth environment, these substances are metabolized through various pathways—including aerobic respiration, anaerobic respiration, and fermentation—to produce electrons, energy (ATP), and essential nutrients required for microbial growth and reproduction.
