Industrial plants and warehouses have large floor drains and central trenches. Sulfur hydrogen from the biofilm corrodes reinforcement bars, installations, and electronics. Methane and other gases accumulate in poorly ventilated spaces—an explosive hazard. Green Drain™ is a safety measure, not a luxury.
In the large plant, everyone watches their own job—no one looks at the floor drains. Biofilm grows, H₂S corrodes metal, and gases accumulate.
EU Directive 2014/34 (ATEX) regulates the protection of equipment for explosive atmospheres. The Labor Inspectorate oversees hazard control measures for workers in industry. For food logistics, BRC and IFS audits require environmental monitoring as standard.

The industry has scheduled shutdown periods. Our technicians enter during that window, install, and then exit.
Plant mapping — process, cold storage, shipping, sanitation.
The QHSE department is taking over the documentation for environmental compliance.
One line or chamber — 30 days, H₂S measurement at strategic points.
During the planned shutdown — the entire plant in 1–3 days.
Industrial facilities in Croatia include manufacturing plants (Rimac, Cromos, Saponia), FMCG supplier logistics centres (Atlantic, Nestlé), cold storage facilities (Ledo), distribution hubs (Zagreb Logistics), chemical warehouses, and pharmaceuticals (Pliva, JGL). A typical facility has 4-6 different sizes throughout the building.
Green Drain™ doesn't work alone — for maximum drain control it's combined with GD Uri-Tabs™ (urinals) and GreenSwirl™ (cleaning).
Patented silicone seal for floor drains in manufacturing and warehouses. H₂S and methane barrier. ATEX-compliant design.
Bio-enzyme urinal tablets for workers' restroom facilities. EU 528/2012 BPR, documentation for EHS systems.
Biofilm bio-cleaning in production floor drains. CIP/SIP-compatible, does not compromise chemical compatibility with facilities.
We come to the site, map the drains, and provide a written recommendation—no cost, no obligation.
