Industrial plants and warehouses have large floor drains and central trenches. Hydrogen sulphide from the biofilm corrodes reinforcement bars, services and electronics. Methane and other gases accumulate in poorly ventilated spaces — an explosive hazard. Green Drain™ is a safety measure, not a luxury.
In a big plant everyone minds their own patch — nobody looks at the floor drains. Biofilm grows, H₂S corrodes metal, and gases accumulate.
Directive 2014/34/EU (ATEX) governs equipment intended for use in potentially explosive atmospheres. The State Inspectorate oversees the implementation of occupational safety measures in industry. In food logistics, BRC and IFS audits call for an environmental hygiene monitoring programme.

Industrial sites have scheduled shutdowns. Our technicians go in during that window, fit the seals and are out again.
Plant mapping — process, cold storage, shipping, sanitation.
The QHSE department takes 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™ (drain unblocking).
Patented silicone seal for floor drains in manufacturing and warehouses. H₂S and methane barrier. ATEX-compliant design.
Bio-enzymatic urinal tablets for staff washrooms. EU 528/2012 BPR, documentation for EHS systems.
Biofilm bio-cleaning in production floor drains. CIP/SIP-compatible, and it does not interfere with the plant's cleaning chemistry.
We come to the site, map the drains, and provide a written recommendation — no cost, no obligation.
