This project provides for the purchase and commissioning of new energy efficient equipment recommended by the 4 measures of the energy audit, namely: a new mobile sub-mass recycling system (Measure 1), a new mobile vacuum excavation system (Measure 2), a new microtunneling system (Measure 3) and an automated monitoring and control system for energy consumption (Measure 4).All new assets are of high productivity and low energy consumption. After the introduction of the assets envisaged for purchase, the amount of energy savings of the company and the amount of carbon dioxide emissions saved thanks to the energy efficient machines will increase significantly.The project also foresees the introduction of an energy management system and certification under BDS EN ISO 50001. These activities will reduce the cost of energy resources, limit the consumption of energy resources and thus protect the environment. The project will have a deadline of 24 months and will have a total value of BGN 5 050 141.00 excluding VAT.
