Denmark: New microchip could help reduce food waste at dairies

Researchers from the Technical University of Denmark (DTU) together with three technology companies have developed an ultra-compact optical spectrometer based on a microchip. This device allows precise monitoring of what passes through the pipes – milk, old product residues or cleaning agents. This solution allows for a significant reduction in the amount of milk discharged into the sewer and improves the environmental performance of dairies.

According to Professor Søren Stobbe, head of the Nexus project, current spectrometers in factories cost around 100,000 euros, which makes their use limited. The new compact chip, in turn, is much more affordable, which will allow for more measurement points and more precise control over the production process.

The development is being actively tested, and scientists have high hopes for it. This is not only a cost-effective solution for producers, but also a significant step towards reducing the negative impact of dairy production on the climate. Dairy plants will be able to reduce greenhouse gas emissions, which is especially important considering that one litre of milk is associated with the production of about 3.15 kg of CO2 equivalent.

In addition to the dairy industry, microchips can be used in other food industries, which will improve food security and reduce food waste worldwide.
