Highly durable asphalt modifier made from waste PET

Technology / Service Summary

The features of the technology
・It utilizes waste PET as a raw material and transforms it into a modifier through unique chemical processes.
・It enhances the durability of asphalt pavement when added.
・It can recycle up to the equivalent of 1,400 PET bottles per 500ml PET bottle per 100m2 of asphalt pavement.

Purpose

・The effective utilization of hard-to-recycle low-grade waste PET
・Improving the durability of asphalt pavement

Feature

By utilizing waste PET bottles (low-grade) and discarded PET fishing nets as raw materials for asphalt modifiers, this sustainable technology contributes to the recycling of waste materials.

Effect

By improving the durability of asphalt pavement, it can reduce road surface damage and potentially suppress CO2 emissions from repair work by up to 40%. Furthermore, it is expected to enhance resistance to rutting by up to 5 times and reduce the generation of wear particles from the pavement, thereby contributing to the conservation of marine resources. The technology also allows for improvement in pavement properties such as water resistance, UV resistance, and oil resistance, enabling application in various environmental conditions.
