Bio-based material definition: Materials that utilize renewable biomass or/and are bio-manufactured
Bio-based materials refer to a new class of materials manufactured by biological, chemical, physical and other means using renewable biomass or (and) raw materials obtained through biological manufacturing, such as bioplastics, biomass high functional molecular materials, etc. Bio-based materials are different from traditional chemical material products produced from non-renewable petrochemical resources such as coal and petroleum. They have the characteristics of renewable raw materials, reduced carbon emissions, and energy conservation. Some categories also have good biodegradability. An important direction for the development of the international new material industry. Looking forward to the future, bio-based materials are expected to gradually replace traditional petroleum-based materials in some application fields, become a new industry leading scientific and technological innovation and economic development, and serve as the main way for green and low-carbon development and the highlight of low-carbon economic growth.
At present, common bio-based materials are bio-polymer materials or monomers obtained from renewable biomass such as grains, legumes, straw, bamboo and wood powder through biotransformation, and then further polymerized to form environmentally friendly chemical products and green energy, etc. Polymer materials, such as biogas, fuel ethanol, biodiesel and bioplastics. In addition, biobased materials can also be produced and obtained via engineered or engineered biological systems such as biomanufacturing, biosynthetic methods, and the like.
