Valorisation of whey

Whey is a by-product generated during cheese production.

It is mainly composed of water and, in smaller proportions, lactose, fat, and proteins with high biological value.

At CADÍ SCCL, we process more than 200,000 L of whey per day. We extract whey proteins and produce edible lactose, which is a commodity product.

The energy cost of this process is high, and the selling price is mostly determined by global market prices.

In this context, the valorisation of whey is a challenge, either to reduce the costs of the current production system or to develop new value-added products from its components.
