Bio-based Polyethylene Granules

Production Process of Bio-based PE The core lies in the transformation of raw materials, from "underground oil" to "above-ground plants."

1. Agricultural Planting and Fermentation: Planting high-sugar or high-starch crops such as sugarcane and corn.

2. Ethanol Production: Bio-based ethanol is obtained through the fermentation and distillation of these crops.

3. Dehydration to Ethylene: Bio-based ethanol is dehydrated under the action of a catalyst to produce bio-based ethylene. This is the most crucial step, realizing the transformation from biomass to chemical monomers.

4. Polymerization: Bio-based ethylene is polymerized through the same polymerization reactions as traditional processes (such as high-pressure free radical polymerization and low-pressure coordination polymerization) to produce bio-based polyethylene resin.

5. Processing and Molding: The resin is processed into final products such as plastic bags, bottles, and cans through processes such as blown film, injection molding, and blow molding.

Key Features and Advantages

1. Reduced Dependence on Fossil Resources: Renewable raw materials contribute to energy security and sustainable economic development.

2. Reduced Carbon Footprint: This is its core environmental advantage. Plants absorb carbon dioxide from the atmosphere through photosynthesis during their growth. Incineration releases carbon dioxide at the end of the product's life cycle, but this process forms a "carbon cycle," theoretically achieving carbon neutrality. Compared to petroleum-based PE, its greenhouse gas emissions over its entire life cycle can be reduced by approximately 60%-70%.

3. Performance Identical to Petroleum-Based PE: · Possesses the same mechanical strength, chemical resistance, flexibility, and sealing properties. · Can be directly used with existing plastic processing equipment and processes, requiring no additional investment. · The product can be directly recycled, entering the existing PE recycling stream, achieving a closed-loop cycle.

4. Wide Applications: Can be used in almost all application areas of petroleum-based PE.

Conclusion:

Bio-based PE is one of the important paths for the plastics industry to transition to sustainable development.

It is not a perfect, ultimate solution, but at the current stage, it is a practical and effective option for reducing the carbon footprint of plastics and moving away from fossil fuel dependence.

Its long-term development depends on breakthroughs in non-grain raw material technologies and the improvement of a circular economy system.
