BoReTech: Innovation of PET Recycling with Latest EC Process Technology

In 2022, the subsidiary of BoReTech Group in Taiwan introduced the latest EC process technology of the PET bottle recycling system developed by BoReTech. The EC process has been completed development in 2021, it is the first time to be applied in the PET recycling project.

 

 

The project adopts the hot washing and rinsing modular of the EC process PET bottle washing system. Compared with the traditional recycling process, it includes pre-mixing, hot washing, and drying, but the occupied area is only 110㎡. The entire hot- washing module can replace the hot-washing machine, screw conveyor, and friction washer with the minimum equipment, which reduces equipment and civil engineering investment, and the process design is rationalized, compact and simplified.

 

The special structure design of MegaWasher and the frequency control greatly improve hot washing efficiency and the rPET flakes' cleanliness. The impurity content of the flakes after high-speed hot washing with MegaWasher can be stably produced.

 

 

The Hydro rinsing module includes high-speed rinsing, floating, ultrasonic washing and dehydration, with a total area of about 100㎡. It is applied to PET recycling, either for HDPE, PP, PE recycling. The Hydro Washer replaces the continuous rinsing, which not only occupies a small area but also has higher rinsing efficiency. After rinsing, the pH value of flakes is stable in the range of 7.5±0.5, and the inline water reuse system reduces industrial water by 50%. The structure design of the floating washing machine ensures the material is under the water and achieves the complete separation of the sinking and floating materials.

 

Recently, the FOOD SAFETY AND STANDARDS AUTHORITY OF INDIA (FSSAI) issued direction under Section 16(5) of the food safety and standards act, which involved guidelines for recycling of post-consumer PET for food contact applications. It means that India has opened access to the food-grade application of recycled PET. As the second-largest populated country in the world, India has pushed the global recycled PET food application to a new chapter. The food-grade recycling equipment of BoReTech provides a new option for India to open up food-grade applications for waste PET bottle recycling.
