What Helector does

Helector S.A. (ΗΛΕΚΤΩΡ Α.Ε.) is a Greek environmental infrastructure company that designs, builds, and operates integrated waste management and renewable energy facilities across Southeast Europe. Its technology stack centers on four platforms: separation and sorting systems, anaerobic dry fermentation for biogas production, the proprietary Herhof Stabilat aerobic dry process (which dewaters waste below 15% moisture and converts organic fraction into hygienic pellets suitable as Solid Recovered Fuel), and waste-to-energy conversion. Major assets include the Ano Liosia Mechanical Recycling Plant (300,000 t/y), biogas power plants at Ano Liosia (24.22 MW via JV BEAL S.A.), Tagarades (5.048 MW) and Mavrorachi (3.52 MW), the only licensed medical waste incinerator in Greece at Ano Liosia, the Apotefrotiras hazardous waste facility, and integrated waste treatment plants in Bulgaria (Sofia, 410,000 t/y) and Cyprus (Larnaca, 190,000 t/y).

The business model is built on long-duration public-sector contracts. Helector generates revenue through two primary streams: managed waste services delivered under concession agreements, design-build-operate contracts, and public-private partnerships (PPP) with regional waste management agencies and municipalities; and renewable electricity sales from landfill gas and biogas power generation under exclusive exploitation rights. Customer concentration is heavily weighted to government and municipal authorities in Greece (FODSA Central Macedonia, EDSNA, DIADYMA SA), with secondary exposure to municipal authorities in Bulgaria and Cyprus, plus a distributed healthcare segment covering ~1,800 medical units across Greece for medical waste collection and treatment. Pricing is concession-negotiated and not publicly disclosed.

As of June 2025, Helector operates as a member of the Motor Oil Group, the Greek energy conglomerate, following a new corporate identity launch. The company maintains 14+ subsidiaries and joint ventures including ASA Recycle (recyclables sorting), APOSTEIROSI (medical waste sterilization), EPADYM/EDADYM (Western Macedonia PPP vehicles), EPALTHEA (60% stake, medical waste incineration concession), and international entities in Cyprus, Germany, Bulgaria, and Croatia. The company employs 51-100 people and has received international recognition including the Energy Globe World Award 2023.
