Energy Management
Total Energy Consumption
Note:
- Intensities are calculated based on overall production including inter-company sales.
- 2020 energy has increased as IVL acquired cracker plants, which resulted in higher energy consumption.
- 2020 and 2021 environmental data has been restated using a more stringent definition and methodology.
- 2020 baseline was adjusted for an alignment.
2025 target:
Air Emissions
NOx
SOx
VOCs

Beyond Compliance: Guangdong IVL PET Polymer Kaiping Limited, our wholly-owned subsidiary in China, has undertaken environmentally-friendly initiatives installing a nitrogen oxide (NOx) reduction system valued at over USD 230,000 to reduce NOx values beyond limits permitted by the government. This initiative has resulted in environmental, social and economic benefits which include:
- Less NOx emissions in the air, much lower than permitted levels.
- No solid or liquid contaminant is being generated or secondary pollution during operations.
- Low running costs due to use of less expensive catalysts.
- Easy to handle, transport and store as the new reducing agent is uninflammable and non-explosive.
Indorama Petrochem Limited (PET)’s plant in Rayong, Thailand, continues to demonstrate strong stakeholder engagement and significant process optimizations. At the end of 2019, the plant installed a stripping column to reduce the COD/BOD in wastewater prior to its delivery to a wastewater treatment plant. In addition, a catalytic incinerator was installed to remove any off-gas from the process. In 2020, electrostatic precipitators (ESPs) were used to replace the cyclonic separation process for particulate collection. This initiative reduced total suspended particulates by 91% and reduced the NOx emissions rate by 29%. These actions demonstrate IVL’s solutions that meet or exceed stakeholder expectations.

The IVOX Port Neches Team carried out studies to determine the impacts of bypassing the Propylene Recycle tower, by sending a portion of the propylene stream to the olefins unit tower for processing, with the remainder sent for recycling to Epoxidation. This project is expected to yield an energy reduction of 324,090 GJ/year along with an emissions reduction of 478 metric tons of CO2. The process efficiencies achieved from this project would lead for a total operational savings of US$ 2.6 million.

Optimizing our systems to reduce carbon emissions and energy consumption is integral to reaching our 5% energy intensity reduction by 2025. In support of these reductions, our Trevira Bobingen site in Germany has been utilizing waste heat exchangers. Heat generated by air compressors is recycled and used within the manufacturing process to preheat boiler feed water and finish dip baths. In 2020, This technology achieved an energy saving around 23,740 GJ and reduced carbon emissions of 1,360 tCO2e.
