ERI Eco Reserch Institute Ltd.


Better Performance, Easier to Use and Cheaper Price.
These are the goals requested by customers quite frequently. How can we do it? We need new ways.
The secret of our success is unique paper grinding system by which we can produce our key feedstock quickly and inexpensively. Let us show you the difference briefly. Paper grinding is extremely difficult because of its soft and light fibers.

Capital Infusion Expensive Reasonable
Powder Production Cost Expensive Reasonable

Characteristics of Paper Powder

Paper powder production is only the first step. By using paper as feedstock instead of conventional palstics, customers can reduce the usage of fossil oil materials dramatically. If we use waste paper and recycled plastics for the feedstock of paper powder reinforced plastic composite, we can dramtically improve customer's carbon footprint (green house gas emisssion). But we have to produce high quality plastic pellets consisting of paper powder and plastics so that our customers can mold end products as smoothly as possible using the existing equipment. Our competitors are now facing extreme difficulty to produce the market quality pellets for customers. Paper powder is different from plastics that means the compounding process becomes difficult unless we understand the attributes of paper.

  • Density of paper powder is extremely light.
  • Paper powder is moisture sensitive.
  • Conveying paper into extruder is very difficult.
  • Compounding of paper powder and plastics requires special expertise.

Advantages of Paper Powder

  • Reduction of petroleum-based materials
  • Lower shrinkage rate
  • Improve heat resistance
  • Improve sonic function
  • Improve stiffness and strength
  • Stable supply
