One of Tacsa’s key principles regarding the environment is to control and minimize the environmental impact of our activities.
In order to reduce Tacsa’s environmental impact and minimize the effect on company costs, actions have been implemented in various areas to reduce the energy consumption of our plants.
Actions have been taken to optimize the start-ups and shutdowns of the facilities, insulate pipelines and tanks, switch to products that operate at lower temperatures, install variable frequency drives, replace equipment with new, more energy-efficient models, and we continue working to minimize our consumption, thereby reducing our impact.
Thanks to these actions, reductions in gas and electricity consumption per m² of treated parts have been achieved.
In 2023 compared to 2021, we had a 7% reduction in electricity consumption per m² and a 20% reduction in gas consumption.
In 2024 compared to 2023, there was a 3% decrease in electricity consumption per m² and a 1.4% reduction in gas consumption.
Water consumptionIn order to respond to the exceptional drought situation we experienced and within the framework of our environmental strategy and commitment, a water consumption reduction plan was defined with the goal of achieving an absolute reduction of 25% compared to the total water consumption of Tacsa’s plants in 2022.
To achieve this objective, various actions have been implemented over the past two years (2023 / 2024). The management of incoming water treatment plants, osmotized water, and demineralized water systems has been optimized. A circuit was installed to reuse reverse osmosis reject water in processes that can accept high-conductivity water. The efficiency of the rinsing processes in the cataphoresis line and the degreasing line has also been improved, allowing for a reduction in the amount of fresh water required.
As a result of the implemented measures, water consumption was reduced by 11% in absolute terms in 2023 compared to 2022, and by the end of 2024, we achieved a 28% absolute reduction compared to 2022—thus reaching the initial target.
The reduction in water consumption relative to the treated surface area (per m² of treated piece) has also been significant, reaching a 34% decrease in 2024 compared to 2022 levels.
