Operating across Ireland and Northern Ireland from our Dublin office, part of the Green Flow group. Three proven solutions — Green Drain™ silicone drain seals, GD Uri-Tabs™ bio-enzymatic urinal tablets and GreenSwirl™ drain mineral granules — eliminate sewer gases, odours and pathogens without chemicals, without tools and without maintenance. From Dublin Airport and the Dalata hotel network to Regeneron's biopharma campus and Meta's data infrastructure — Green Flow Ireland supplies drain hygiene to facilities where the standard cannot slip.
Stagnant traps, dry P-traps (the U-bend water seal under each drain), biofilm and pathogen migration aren't a guest problem. They're an operational, compliance and reputational risk that lands on facility managers, technical directors, HSE auditors and procurement teams long before a single guest review mentions it.

Working with hotel groups, hospitals and food producers in Ireland showed us the same gap existed across continental Europe. After market research and first projects on the Adriatic in 2024, we moved the corporate base to Zagreb and kept Ireland as our centre for capital projects.
Green Flow starts in Dublin as a Green Drain™ distributorship, trading through an Irish company. Exclusive distribution agreements secured.
Dublin Airport, Dalata Hotel Group, Kerrygold, Regeneron, Moy Park, University Hospital Limerick, NATO base in Romania. Expansion of operations beyond the local market.
A clear need was identified in the region. The first successful projects on the Adriatic were completed. A decision was made to relocate the headquarters and launch a regional expansion.
GREEN FLOW d.o.o. was established at Savska cesta 41, Zagreb, and became the sole trading entity across all markets. Consolidating into one EU company put supply, invoicing and warehousing in a single place and closer to the growing Adria customer base. All contracts and invoices now come from Zagreb; the Irish base and phone line remain.
Two new products now available on the EU market. A complete drain protection portfolio without the use of hazardous chemicals. Revenue target of €1 million.
Regional expansion into new markets. We are seeking local distribution partners.
