The PET bottle-to-bottle project jointly launched by BoReTech and Chiripal Group in India entered trial operation in early April 2026.

This project includes BoReTech's complete ES process washing, food-grade pelletizing, and solid-state polycondensation (SSP) systems, with a PET bottle washing line capacity of 30,000 tons per year and an hourly output of 2,000 kg of food-grade rPET pellets.

Core process: Integrated design enhancing efficiency and quality

In the washing stage, BoReTech's ES process is built around modularization and process integration. It reduces floor space by nearly one-quarter, the intensive washing technology improves downstream pelletizing filtration performance by 25%, on-line labor requirements are reduced by one-third, and energy consumption per ton of finished product is lowered by 13.3%.

In the pelletizing and SSP stages, through the coordinated operation of pretreatment, specially designed screws, and a pelletizing system, combined with continuous solid-state polycondensation, the molecular weight of the recycled material is enhanced to meet food-grade standards.

The washing, pelletizing, and SSP processes are directly connected to form a highly integrated production line, ensuring product quality and safety.

Safe for direct food contact and internationally certified

BoReTech's PET bottle-to-bottle recycling process received No Objection Letters (NOL) from the U.S. Food and Drug Administration (FDA) in 2023 and 2025, as well as a positive scientific opinion from the European Food Safety Authority (EFSA) in 2025, making it the first Chinese company to hold both EFSA and FDA certifications as a full-process solution and equipment supplier for PET bottle-to-bottle food-grade recycling.

The rPET pellets produced by this production line are suitable for direct food contact applications.

BoReTech’s strong presence in India

BoReTech holds over 80% market share in India's PET bottle recycling and recovery sector and continues to deepen its local presence.

On February 2, 2026, BoReTech India officially opened for business, further strengthening its local technical service capabilities and enabling more efficient response to on-site project needs.

With experience from more than 78 washing line projects in India, BoReTech has developed deep insights into local feedstock characteristics, effectively addressing challenges such as high levels of sediment, shrink sleeves, and aluminum caps.
