Belarus is leading in the production of whey, with a focus on whey powder and whey-based drinks. The lack of popularity of these drinks, despite being unique to the country and having no equivalents, is attributed to marketing and sales challenges. The country's unique processing of sour whey, which is used in large quantities due to cottage cheese production, has helped convert whey from feed to food. This technology is not widely used elsewhere, with Holland being the only competitor.
