Traidenis

What Traidenis does

Traidenis (UAB "Traidenis") is a Lithuanian private limited company founded in 1996, headquartered and manufacturing in Alytus, Lithuania. It is the first company in Lithuania to produce wastewater treatment equipment from fiberglass and is now one of the largest Lithuanian manufacturers of wastewater treatment plants and fiberglass (GRP/GFK) tanks and reservoirs. The company serves private homeowners, municipalities, industrial facilities, gas stations, agricultural operations, and biogas plants across 27+ countries in Europe, Central Asia, and South America.

The company's core technology is cross filament winding of fiberglass composites, producing tank walls with mechanical strength up to 432 MPa and elasticity modulus up to 14.3 GPa — substantially stronger than spray-up method alternatives. The product portfolio spans two main categories: (1) wastewater treatment equipment including NV-type biological plants for individual homes (95-98% pollutant removal), modular biological systems for settlements, industrial wastewater treatment with flotators, oil separators achieving 5 mg/l oil concentration, grease traps, sand traps, pump stations, and railway oil collection systems; and (2) GRP tanks including chemically resistant tanks (pH 0-14, -50°C to +150°C), fuel tanks, drinking water tanks, thermo-insulated tanks, modular tanks up to 5,000 m³, dome roofs up to DN 21.05m, firewater reservoirs, biogas scrubbers, and silo tanks. A closed recirculation aquaculture system (RAS) for fish farming extends the portfolio into adjacent water management. Manufacturing is vertically integrated across forming, winding, and assembly workshops, supported by ISO 9001 (2008) and ISO 14001 (2004) certifications and UN Global Compact membership since 2005.

Traidenis operates a sales-led direct model with regional partner offices in Ukraine, Poland, and Moldova, and direct exports to 27+ countries. Revenue is generated primarily through one-time equipment sales (wastewater treatment plants, tanks, scrubbers, oil separators) supplemented by consulting, design, and maintenance services. Pricing is quote-based, with products ranging from small residential units (5-10 m² footprint, 5-10 EUR/month operating cost) to large industrial installations (5000 m³ modular tanks, 1.6 MW biogas scrubbers). The company is privately held with no disclosed institutional investors, no parent company, and only two identified members of the management team (CEO Sigitas Leonavičius and Export Key Account Manager Vytenis Leonavičius).
