Bio-based materials are materials prepared from renewable biomass (plants, microorganisms, waste oils, etc.) through bioconversion, chemical synthesis, or physical processing. Bio-based products are wholly or partly derived from materials of biological origin (such as plants, animals, enzymes, and microorganisms, including bacteria, fungi and yeast). Their core characteristics are low carbon, renewability, and partial biodegradability. They are used to replace petroleum-based materials, aligning with "dual carbon" (carbon dioxide, oil, and gas) and green supply chains. I. Core Concepts and Common Confusions - Bio-based ≠ Biodegradable: Bio-based depends on the source of the raw materials (renewable); biodegradable depends on whether it is decomposed by microorganisms after disposal (...

OBP (Ocean Bound Plastic) refers to environmentally friendly raw materials made from recycled plastic waste within 50 kilometers of the coastline that has not entered the sea. The core categories are OBP-PE/PP/PET/PA/PC/ABS, emphasizing low carbon footprint and traceability. Marine plastic debris (OBP) refers to plastic waste that "poses an eventual loss to the ocean." It is estimated that marine plastic debris accounts for 80% of all marine plastic waste. It includes: A small portion of commercially recyclable plastic waste   A large portion of non-commercially recyclable plastic waste   I. Core Definition and Classification - Definition: Recycled plastic waste from within 50 kilometers of the coastline (including beaches, estuaries, and near-shore fisheries), processed throug...

PCR plastic short for Post-Consumer Recycled Plastic, refer to plastic materials made from recycled consumer plastic waste through processes such as sorting, washing, crushing, and granulation. This effectively reduces plastic pollution and the use of virgin plastics. - Core Advantages: Strong environmental attributes, reducing carbon footprint and petroleum resource consumption; some modified PCR materials have performance close to virgin materials, offering better cost-effectiveness; aligns with global trends of "plastic reduction" and "carbon neutrality," meeting the sustainable development needs of brands. - Common Categories: Mainstream types include PCR PP, PCR PE, PCR PET, PCR ABS, and PCR PC, suitable for various processing techniques such as injection molding, blow molding, and...

In September 2020, China explicitly proposed the goals of "carbon peaking" by 2030 and "carbon neutrality" by 2060, advocating a green, environmentally friendly, and low-carbon lifestyle.   These dual carbon goals accelerate the pace of carbon emission reduction, which is conducive to guiding green technology innovation and enhancing the global competitiveness of the country's industries and economy.   In June 2022, the Guangdong Provincial People's Government issued the "Implementation Plan for Carbon Peaking in Guangdong Province," which proposed promoting carbon peaking actions in the petrochemical industry and promoting the application of technologies and equipment such as raw material optimization, material recycling, and process reengineering.   Recently, the "Interp...
