The company Aitasa has announced the construction of a new water recirculation plant at the petrochemical hub in Tarragona, aiming to increase the chemical sector's water efficiency in the coming years.

The new infrastructure will complement the existing water regeneration plant, which will also undergo an expansion. This project will increase treatment capacity from six to nine cubic hectometers per year. According to projections by the Associació d'Empreses Químiques de Tarragona (AEQT), these improvements are expected to ensure that 40% of the total water used by companies in the complex is either regenerated or recirculated within two to three years.
Currently, 20.51% of industrial water consumption comes from treated urban wastewater. With the expansion of the regeneration plant, this figure is expected to rise to 25%. The technical difference between the two processes lies in the treatment: regenerated water undergoes an additional process to remove contaminants, while recirculated water is integrated into a closed industrial circuit.
Furthermore, the chemical sector has expressed concern over high energy costs, which they believe reduce competitiveness compared to other international markets. Additionally, the AEQT has highlighted the economic impact of so-called adjustment services, which have increased the electricity bill by 30 euros per megawatt-hour.
Finally, the business association reported that it is in talks with telecommunications operators to install a 4G antenna in the southern industrial estate. The goal is to resolve coverage deficiencies that affect the daily operations of companies located in this area.
