MERLIN Properties and Sacyr Facilities introduce an innovative and sustainable cleaning system through Ozoniza in Torre Castellana 259B, Madrid

  • MERLIN Properties and Sacyr Facilities, to keep their commitment to promoting technology, development, and environmental care, will introduce an innovative and environmentally responsible cleaning system based on the on-site production of ozone water (O3) to clean the exterior of one of the company’s most emblematic assets: Torre Castellana 259B.

Ozoniza (, the chosen provider to carry out this sustainable and innovative cleaning solution, is a 100% Spanish capital company and a leading developer of end-to-end cleaning and maintenance solutions for all kinds of spaces: commercial, industrial, offices, restaurants, hospitality, healthcare, etc.

MERLIN Properties and Sacyr Facilities, through this collaboration with Ozoniza, will continue to expand the array of activities and sustainable projects encompassed in their sustainability, CSR, and ESG plan. To do this, we will reduce 100% of packaging, chemicals, and detergents that cleaning staff used up until now to do maintenance work on the tower situated in the financial area of Madrid’s northern district. In turn, Ozoniza will associate its professional project with two companies committed to their corporate missions and visions, encouraging it to continue developing its portfolio of technologically efficient and environmentally respectful solutions.

This first collaboration project between MERLIN Properties, Sacyr Facilities, and Ozoniza will go on throughout the second half of 2021 and entails total reduction of plastics, detergents, bleaches, and chemical products intended for cleaning purposes in the said tower. This is to maximize the care and protection of the staff that carries out that activity by replacing chemicals with ozone water, which causes no skin reaction.

REIT MERLIN Properties has always stood out for being a leader and example in real estate. According to the company's CSR memory, its commitment is no other than to obtain sustainable profit that guarantees business success and takes the shareholders' expectations into account by significantly reducing the carbon footprint and strengthening its ESG plan.
