Case Study

Energy efficient modernization of Romanian vinegar production

Acetica SRL is a Romanian vinegar producer since 1976. The initial production capacity of the plant has increased by five times reaching 25,000 of hectolitres per year.

The company decided to invest in energy efficient modernization of the production and addressed RoSEFF for financing.
The RoSEFF team performed analysis of the energy saving potential of the company and of the suggested measure, its financial-technical parameters and profitability of the project.
The final project comprised replacement of the four old wooden tanks with a single large stainless steel tank for vinegar fermentation.
The overall €298,900 investment allowed the company to decrease its energy consumption by 73%, while increasing the production volume by two times. The new equipment will also decrease the production period to 2-3 days instead of 7-8 days. The operation time decrease comes from the fact that the previous fermentation and acetic bacteria activity, allowed by circulating the liquid through several wood filling materials and wooden tanks, will now happen thanks to forced aeration and oxidation in one single tank.
In addition, the project delivered a substantial environmental impact by decreasing the CO2 emissions by 1,135 tonnes per year.
With this project the company achieved significant reduction of the operation costs and, therefore, will become more flexible and competitive at the market.
This way, the EBRD and RoSEFF support the sustainable financing and implementation of energy efficiency and renewable energy projects by the private sector. Together, the private, residential, and public sectors can make a change in the energy consumption patterns and environmental protection.
