Thermofusion recycling process for high-density polyethylene (HDPE) materials

Overview

Santibu has developed a patented thermofusion process that enables the 100% circular recycling of high-density polyethylene (HDPE) waste into new, durable materials in sheet and block formats. This innovative process combines pressure and heat to transform HDPE into a versatile product with exceptional properties such as thermal, mechanical, and chemical resistance. This technology is particularly advantageous for industries requiring materials with high impact resistance, waterproofing, and thermal and electrical insulation.

Technical specifications

The thermofusion process involves several key steps: washing, chipping, applying heat and pressure, and cooling, all while maintaining temperature ranges to prevent oxidation or burning of the material. The process is straightforward, not requiring specialized labor or machinery, making it easily adaptable to existing production lines. The resulting material is:

• Antibacterial and non-toxic
• Resistant to atmospheric changes
• Capable of withstanding 90 tons of impact without dimensional changes
• Customizable in finishes and colors
• Textured and easy to clean

Applications include construction, where it can serve as a fireproof structural material, and mining, where it can support structural frames for mining deposits.

Technology readiness level

This technology is currently at Technology Readiness Level 6, having been validated in relevant environments, and is poised for further development and commercialization.
