What Bondalti does

Bondalti is a privately-held Portuguese industrial chemical group operating across three core business units: Chemistry, Water, and Energy. The Chemistry division produces chlor-alkali products (chlorine, sodium hydroxide, sodium hypochlorite, hydrochloric acid, hydrogen) via electrolysis and aniline derivatives (aniline, nitrobenzene, cyclohexanol, cyclohexylamine, nitric acid, sulfanilic acid), with Bondalti positioned as the largest Portuguese chemical company, a leading Iberian chlorine producer, and a European leader in aniline sales. The Water division provides comprehensive treatment solutions including process water, drinking water, wastewater, desalination, reverse osmosis, MBBR, MBR, and SBR systems, plus laboratory, biogas, and smart water digitization services, serving industrial and municipal customers across pharmaceuticals, food and beverages, pulp and paper, textiles, automotive, plastics, and mining/metallurgy sectors. The Energy division focuses on green hydrogen and green lithium initiatives.

Bondalti generates revenue through B2B direct sales of commodity chemicals in bulk and packaged formats, quote-based pricing for chemical and water treatment solutions, and recurring service contracts for water treatment operations and laboratory services. The company sells to enterprise industrial customers across eight or more horizontal sectors, with export presence to more than 50 countries. Manufacturing operations span Estarreja (Portugal), Torrelavega, and Alfaro (Spain), with logistics in Vigo and sales offices across Spain. In March-April 2026, Bondalti completed a €247.5 million hostile takeover of Spanish chemical and pharmaceutical company Ercros, acquiring 77.23% of voting rights and positioning the combined entity as a leading Iberian chemical champion. The firm is backed by family conglomerate Grupo José de Mello, which reported €1.487 billion in 2024 turnover and employs more than 8,800 people group-wide.

Product overview

Bondalti is a Portuguese industrial group operating three core business units: Química (Chemistry), Água (Water), and Energia (Energy). The Chemistry division encompasses chlorine-alkali products (chlorine, sodium hydroxide, sodium hypochlorite, hydrochloric acid, hydrogen) and aniline derivatives (nitric acid, sulfanilic acid, aniline, cyclohexanol, cyclohexylamine, nitrobenzeno). Bondalti is the largest Portuguese industrial chemical company, the largest Iberian chlorine producer, and a European leader in aniline sales. The Water division offers comprehensive water treatment solutions including process water, drinking water, wastewater treatment, and technologies like reverse osmosis, desalination, anaerobic treatment, and smart water digitization. The Energy division focuses on green hydrogen and green lithium initiatives as part of the company's sustainability strategy. Following its successful takeover of Spanish company Ercros (completed April 2026 with 77.23% acceptance), Bondalti has expanded its Iberian chemical footprint, integrating Ercros's operations into the group while maintaining both brands.
