What Interplast does

Interplast S.A. (ΙΝΤΕΡΠΛΑΣΤ Α.Ε.) is a privately held Greek industrial manufacturer, founded in 1998 and headquartered in the Komotini Industrial Area, that produces integrated plastic and brass piping systems for water supply, heating, cooling, air conditioning, and sewage applications. The company's product portfolio spans polypropylene (PP-RCT) pressure pipes (AquaPlus), cross-linked polyethylene pipes with oxygen barrier (ComoPex), multilayer aluminum-composite pipes (ComoPexAlPex), medium-density polyethylene pipes (ComoFlex), polypropylene drainage systems (Unisol, AtlasPlus), mineral-filled sound-absorbing drainage pipes (Atlas Plus Echo Silent), underfloor heating (ClassicFloor), Knauf-distributed dry-screed underfloor heating (ecoFloor), geothermal pipe systems (GEO-Flex), and a proprietary multi-layered fire-retardant polypropylene system (FIREBLOCK / Firefighter Plus) co-developed with the International Hellenic University under EU funding. Products exceed European EN, German DIN, Spanish UNE, British BS, and American ASTM specifications, and pass semi-annual inspections by official institutes.

The company operates two manufacturing facilities — plastics in Komotini and brass products in Athens (Acharnai) — supported by sales and exhibition offices in Thessaloniki, and employs approximately 180 people (140 in Komotini). Revenue is generated through one-time hardware sales of piping systems distributed via direct enterprise sales to large project developers, an installer/partner channel program within Greece, and direct export relationships across more than 75 countries. Named enterprise references concentrate in hospitality (luxury hotels and resorts across Greece, Cyprus, and the Maldives), healthcare (Magdi Yacoub Heart Center Cairo, Interbalkan Medical Center), retail (Prishtina Mall), entertainment (LEGO Factory district heating Hungary), education (University of Galway), and marina infrastructure (Ayia Napa Marina).

Ownership rests with the Rizopoulos family, with Chairman/CEO Tasos Rizopoulos leading a multi-generational management team including General Manager John Rizopoulos and Director of Financial Services Zoe Rizopoulou. The company is privately held with no institutional investors or parent company disclosed; growth capital has come primarily from EU structural programs (ESPA, RESEARCH-CREATE-INNOVATE, QUALITY UPGRADING) channeled into R&D, product innovation, and manufacturing upgrades. Pricing is not publicly disclosed and is gated through a downloadable price catalog available to registered partners.
