For more than 20 years, HELECTOR has worked in the field of waste management and green energy production. Its significant expertise and specialization allow HELECTOR to provide integrated waste management solutions, including the design, construction, and operation of modern waste treatment plants, as well as alternative fuel production and biogas and biomass energy recovery projects.

Mavrorachi landfill site has operated in the greater area of Langadas Municipality of Thessaloniki, Greece, since 2008. In support of the European goal of a successful and sustainable transition to a climate-neutral economy by 2050, HELECTOR was chosen to build and operate a modern power plant that would be powered by landfill gas (LFG) and supply the local area with electricity.

Jenbacher cogeneration for improved air quality

Since August 2020, HELECTOR has operated the Mavrorachi LFG Power Plant, where three of INNIO Group’s Jenbacher J416 engines each supply 1,173 kW of power. With a corresponding permit of up to 3.52 MW, the power plant is individually interconnected with the HEDNO medium-voltage substation near Liti village.

Clarke Energy Hellas LTD, the authorized distributor of INNIO Group’s Jenbacher engines in Greece, was responsible for the engines’ supply and commissioning.



Because the landfill gas produced in the landfill cells is collected and transferred to the power plant, renewable electrical energy is generated and greenhouse gas emissions are avoided, significantly improving air quality.

The project was so successful at turning waste into energy while reducing methane emissions that it received the Energy Globe Award in 2023 in the AIR category. According to the award: “The 3.52 MW landfill gas power plant effectively mitigates methane emissions and showcases the global potential of scalable waste-to-energy projects.”
