In this case example, the conductivity sensor was previously used in cream push-out, however it was inaccurate and reacted slowly to the cream/water interface, leading to losses of 500 liters of product in each push-out. With Collo, the optimal timing prevents losses. Cream is one of the costliest dairy products to produce and is also very costly to dispose of as waste.

ahead of environmental targets that loom in the near future, mainly in 2025 and 2030. Most of the greenhouse gas emissions caused by dairy operations originate at the farm. For instance, Nestlé, in its sustainability report , outlines how just five per cent of its greenhouse gas emissions comes from its own operations, whereas 95 per cent is made up of emissions in the supply chain. Raw milk production is the largest single source of emissions in dairy production, which any waste of milk-based raw material needs to be prevented and, preferably, eliminated. Other companies have similar targets. Danone is committed to reducing its own greenhouse gas emissions by 47.2 per cent by 2030 and those in the supply chain by 42 per cent. Fonterra aims to reduce manufacturing emissions by 50 per cent by 2030. The year 2025 is an important milestone for many companies, as the 2030 Agenda for Sustain- able Development was adopted by all United Nations members in 2015 and many companies set themselves 10-year targets at the time. The European Union is committed to implementing the UN Sustainable Development Goals and the CSR Directive is one way the business community is made to play its part.
In addition to the regulatory requirements, changing consumer preferences is another powerful incentive for dairy producers to implement more eco-friendly production methods. A study by McKinsey and NielsenIQ found that products making claims related to sustainability have faster market growth – over a five-year time span, such products grew about 18 percent more than the expectation was at the begin- ning of the period.
“Waste in dairy processes needs to be reduced. Environmentally compatible processes are demanded by regulators and consumers alike. Wasting hundreds of liters of valuable product in every batch makes no sense when this can be prevented with the right technology. But it does not end there. With Collo’s versatile technology we can help plants reduce water use too, an area which is also of keen interest for our customers and regulators alike. Working together with its customers, Collo can play a significant role in achieving a more sustainable dairy process,” concludes Järveläinen.
