Whey Production โ Whey production refers to the total quantity of whey generated during the processing of milk into cheese, casein, yogurt, and other dairy products over a specified period, typically measured in metric tonnes. Whey is the liquid by-product remaining after milk has been curdled and strained and contains proteins, lactose, minerals, and water. This indicator measures the volume of whey produced by the dairy industry before it undergoes further processing into products such as whey protein concentrate (WPC), whey protein isolate (WPI), whey powder, lactose, or other dairy ingredients. It serves as an important indicator of dairy processing activity and the availability of whey as a raw material for food, beverage, nutrition, and animal feed industries.
Production continued to decrease in the following years, reaching 345.17 thousand tonnes in 2017 and 315.74 thousand tonnes in 2018, representing a significant reduction from the beginning of the period. In 2019, whey production declined further to 310.17 thousand tonnes, marking the lowest production level recorded between 2015 and 2023. However, the industry began showing signs of recovery in 2020, with production increasing to 317.20 thousand tonnes, followed by a stronger improvement in 2021 at 369.73 thousand tonnes. Production remained stable in 2022 at 370.63 thousand tonnes and increased further to 384.46 thousand tonnes in 2023. The recovery indicates renewed activity in Germanyโs dairy processing sector, particularly in cheese production and the utilization of whey as a valuable dairy ingredient. Germanyโs whey industry benefits from advanced dairy infrastructure, efficient processing facilities, and strong demand for whey protein concentrates, whey powders, and other functional dairy ingredients. The country also plays an important role in the European dairy supply chain, with whey products used in food manufacturing, sports nutrition, pharmaceuticals, and animal feed applications. Overall, German whey production declined from 400.46 thousand tonnes in 2015 to 384.46 thousand tonnes in 2023, but the industry showed substantial recovery after reaching its lowest point in 2019. Increasing investment in sustainable dairy processing and value-added whey applications has helped strengthen the sector. The growing demand for protein-rich products and improved processing technologies is expected to continue supporting Germanyโs whey industry in the future.
