LANDFILL GAS RECOVERY IN TAGARADES, WITH ITS FURTHER UTILIZATION IN COGENERATION

"Helector"​ (2019)

The purpose of the project was to introduce energy-saving technology for the collection and utilization of landfill gas (LFG) formed through the anaerobic decomposition of organic waste at a solid waste disposal site (SWDS) in Thessaloniki, Greece. The SWDS is located in the village of Tagarades. The project aimed to harness the energy potential of LFG, converting it into a renewable source of electricity while significantly reducing greenhouse gas emissions.

Construction of Gas-Collecting Wells

The project involved the construction of gas-collecting wells at the landfill site in Tagarades. These wells were designed to capture LFG efficiently, ensuring the maximum collection of gas produced by the decomposing waste.

The wells were strategically placed to cover a significant portion of the waste, enhancing the overall efficiency of gas capture.

Local Transport and Treatment System

The captured LFG was transported through a dedicated system to a central treatment facility. This system was crucial for purifying the gas, removing contaminants, and preparing it for use in energy production.

After treatment, the LFG was delivered to cogeneration equipment for electricity production.

Electricity Production and Supply

The cogeneration equipment, fueled by the treated LFG, had the capacity to produce approximately 41,000 MWh of electricity per year.

The generated electricity was either supplied to the local grid or used to meet the plant’s own energy needs, contributing to the region’s renewable energy supply.

Greenhouse Gas Emission Reduction

The project significantly reduced methane emissions by capturing and utilizing LFG, a potent greenhouse gas. This reduction in methane emissions contributed to a substantial decrease in overall greenhouse gas emissions.

The project achieved an estimated annual emission reduction of 127,126 tons of CO₂-equivalent during the first commitment period, with a projected reduction of 158,901 tons of CO₂-equivalent for the subsequent period.

Environmental and Economic Impact

The project led to the issuance of 286,027 European Reduction Units (ERUs), highlighting its success in reducing greenhouse gas emissions.

This initiative not only supported Greece’s environmental goals but also demonstrated the economic viability of landfill gas utilization as a renewable energy source.
