“During the pilot phase, the plant will produce 5 tons of lactic acid per year. There are plans to increase production to 5,000. Ringtone, Ringtone. This amount would be enough to cover most of the demand for this product in our country,” we read in GO! Magazine, the Orlen Group’s internal periodical.
Lactic acid is one of the basic raw materials used in many industries, for example in Food IndustryAs an acidifying agent and preservative, in the confectionery industryTo improve the structure and volume of baked goods or in Pharmaceutical and cosmetic industryThis compound and its derivatives act as hydrating and brightening ingredients for the skin.
Lactic acid can also be used For the production of environmental materials alternative to plastic. “Polylactic acid made from it is used to produce biodegradable bases, plates or cups. Under the right conditions, they turn into water vapor and ash after 80 days” – the article reads.
In the production of lactic acid in the bio-refinery in Trezbinia, microorganisms will be used, and the inputs to the stabilization will be primarily molasses, a by-product of sugar production. The molasses will go to the bioreactor, where the microorganisms that feed on it break down the sugars. The fermentation process occurs and as a result lactic acid is formed.
When in July 2020 PKN Orlen announced the start of construction at the plant in Trzebinia, he confirmed that global production of lactic acid was estimated at 520 thousand. tons annually. The concern also noted that so far no lactic acid was produced in Poland, and that its shortage in the entire region of Central and Eastern Europe forced the recipients of this raw material to import from Asia and Western Europe.
According to PKN Orlen at that time, the Polish company AB Industry became the contractor for the investment in Trzebinia, where the cost of building a lactic acid plant was estimated at PLN 7.5 million.
In 2017, Orlen Południe received PLN 2.38 million in funding from the INNOCHEM Sector Program of the National Research and Development Center for the implementation of the project “Development of the biotechnology conversion of raw materials of organic origin into lactic acid using microorganisms”.
