Asset Utilization, Energy, Emissions

We comply with all regulatory requirements and plan production to optimize efficiency and minimize raw materials, energy, and emissions. AmSty tracks Scope 1 and Scope 2 emissions from our facilities, and we are working to determine the best path for capturing the data necessary to calculate and disclose our Scope 3 emissions. We ensure our emissions tracking and reporting processes are consistent, compliant, and standardized so they can be shared with stakeholders. In 2022, AmSty reported to both the CDP (formerly the Carbon Disclosure Project) and Ecovadis platforms.

Our CO₂ emissions over the past five years have been consistent on an intensity basis and varied on an absolute basis due to occasional turnarounds or other downtime. Our styrene plant in St. James uses more than 85% of all energy consumed by AmSty plants and is a key focus for energy reduction projects. To improve energy efficiency and reduce emissions, we are upgrading process control capability for styrene distillation and redesigning flare management. Furthermore, we are implementing a major capital initiative to improve overall reliability at St. James that includes replacing end-of-life boilers and reactors with state-of-the-art technology. In addition to reliability benefits, this modernization will deliver gains in energy and raw material efficiency.

We are also looking to the future with a conversion from fossil fuel energy to renewables, with our first solar power project at our polystyrene plant in Cartagena, Colombia. We recently installed 185 solar panels on the roof of several buildings to generate more than 150,000 kilowatt hours of clean energy and reduce carbon emissions by over 30 tons annually. Another step forward in our ongoing journey to reduce emissions.
