Indorama Ventures in Kaiping, China, successfully commissioned a new wastewater treatment system.
A new wastewater treatment system (Ultrafiltration Membrane System) was successfully commissioned in June 2023 with good collaboration between our internal capability’s engineers and the suppliers.
This project enables the Green/Hill site to further reduce its water consumption by around 100 tons per day, which is equivalent to about 30% of the total water usage and may possibly support Indorama Venturer’s target of reducing water intensity by 10% by 2025.
To date, the team has reached the target of zero discharge of wastewater for both the Changsha site and the Green/Hill site. It marks a significant milestone on Fibers’ continuous improvement journey in terms of sustainability and cost structure.
IVPSA plant reduces raw and potable water consumption
With 100% of wastewater being recovered at IVPSA’s plant in Ipojuca, Brazil, three projects were implemented to reduce both raw and potable water consumption onsite. Two raw water projects aimed at recovering part of the Water Cooling Tower purge while taking advantage of rainwater during the winter season. The first project treats the Cooling Tower purge in a coagulation/sedimentation system, followed by a reverse osmosis machine which removes antimony and phosphorus salts. This allows the water to be reused in the tower reducing raw water consumption by 26,000 m3/year. The second project, which runs until 2020, transfers and reuses rainwater from the PET resin warehouse to the contention basin and is expected to reduce consumption by 20,000 m3/year (saving USD 5,000 per year). The potable water project consists of a comprehensive set of actions, including individualizing water measurements to the different buildings, replacing potable water with raw water in drainages, as well as for gardening and lavatories, in addition to training programs. This project is already underway providing a reduction of 28,500 m3/year and saving USD 100,000 per year.
Harvesting Rain Water
IVL Dhunseri Petrochem Industries Private Limited, an IVL subsidiary located in Panipat, India, established a rainwater harvesting system at its plant in 2017 to supply surface water to subsurface aquifers (before it is lost as surface runoff). The amount of rainwater estimated to percolate into the ground is over 41,500 m3/year, which amounts to over 30% of 2017 annual fresh water withdrawn by the plant. This water will be free of pollutants as well as salts, minerals and other man-made contaminants, and will help in reducing soil erosion and contamination of surface water with pesticides and fertilizers by replenishing groundwater. We have plans to extend this system to additional sites in the future.
Water Saving from Road Transportation Sanitization Technology.
Innovation technology of a sanitization process with lower water in Brazil, some products are micro-susceptible and need a process of the bulk road transport sanitization to guarantee all the specifications of the product to the client. During 2021, we developed a new technology that avoids using 90% of water to sanitize those vehicles and, in 2022, about 30% of the road transport operations were carried by bulk vehicles that were sanitized by this new technology. More than 1,222 tons of water were saved in this project, and more sanitizers are being homologated in 2023 to increase this technology to more clients.
