Aden Supports The Kubratovo Wastewater Treatment Plant

Aden Supports The Kubratovo Wastewater Treatment Plant in Bulgaria.

The Kubratovo Wastewater Treatment Plant in Bulgaria, is the project Aden have chosen to support this quarter.

The project is both a methane emissions reduction and energy project. The overall objective of the project is to provide an environmentally friendly treatment process while reducing methane and carbon dioxide emissions.

The project is expected to reduce emissions by around 61,000tCO2e per year.

The methane produced in the Kubratovo wastewater treatment plant is captured in methane tanks serving as a buffer, then supplied to the installed Combines Heat and Power (CHP) gas engines, for electricity and heat production. Which in turn substitutes both the plant’s electricity purchases from the grid and fossil fuel usage. The excess electricity is then supplied to the grid.

The purpose of the project is to transform the existing low tech sludge treatment process at Kubratovo that existed before implementation of the project into a modern advanced treatment process matching the best sludge treatment practice available in Western Europe. This transformation has a major positive effect on the environment through dramatically reducing the existing methane gas emissions at the plant while also reducing the volume of sludge (to as much as 50%) that needs to be transported, hence reducing GHG emissions from transportation as well (not included in GHG abatement calculations).

This project comes with a Gold Standard (Climate Security & Sustainable Development) certificate and all the information on it has been given to us by Carbon Footprint Ltd.
