Greek dairy company Kri Kri is implementing an investment of €4.5 million for the creation of a state-of-the-art anaerobic treatment system unit at its facilities in Serres, northern Greece, in the context of its transition to the cyclical model of sustainable development and prosperity, as noted in a relevant press release.
This particular unit will produce biogas using exclusively as raw material the liquid waste from the ice cream and dairy plant as well as the whey resulting from the draining of yogurt. The produced biogas will then be headed to the 998kW electricity and heat cogeneration unit. The electricity will be available to the HEDNO SA (Hellenic Electricity Distribution Network Operator) network, while the generated heat will be utilized within the facilities, helping to reduce the use of natural gas.
According to the company, the investment is expected to have multiple environmental benefits. The reduction of the annual CO2 emissions in the factory is estimated at 800 tons per year, due to the coverage of its thermal needs by 21%. Furthermore, the estimated annual production of clean electricity will amount to 7,500 MWh, which is the amount of energy required to meet the needs of more than 2,000 households. Finally, it is estimated that a reduction in consumption of 80,000lt of oil per year will be achieved just by stopping the transfer of whey by tank trucks to third party units.
The investment is going to contribute significantly to the national economy, as well as to the local community of Serres since a significant number of new jobs will be created.
