FOOD & BEVERAGE
transport the same amount of milk solids in powder form. Additionally, utilising milk powders in place of fresh milk eradicates the requirement for cold storage. By transporting milk product more efficiently, using less fuel and producing fewer emissions, food manufacturers can reduce their carbon footprint and help to mitigate climate change.
MAINTAINING SUSTAINABLE FOOD SAFETY
Adopting more environmentally friendly methods of dairy production can aid the mission to a greener future. In New Zealand, new technology has been employed to reuse water from the condensation process involved in the production of milk powder. The ‘reclaimed’ water system is expected to save half a million litres of groundwater daily. Additionally, one of the most sustainable methods of reducing waste is implementing inspection technology into milk powder production lines. Metal detection, X-ray and checkweighing systems help dairy processors address critical waste, sourcing and sustainability challenges by targeting operational inefficiencies, including upstream product giveaway, non-conforming food packs and packaging and contamination issues. The world’s largest producer of Whole Milk
Powder located in New Zealand recently updated 56 of their Fortress metal detectors to Stealth technology. By adding data logging capabilities and new software algorithms, this processor increased the stainless steel detection sensitivity to 2mm. “The cycle of parts breaking down, being
goods that contribute significantly to our global food waste issue. It is clear that today’s industrial agricultural and food production methods are severely damaging the environment and are not sustainable with the growing global population. Whole Milk Powder and Skimmed Milk Powder, along with other dairy by-product commodities could potentially provide a more sustainable solution.
With an escalating demand in pre-prepared
foods, baby foods and infant formula, as well as new vitamin-fortified milk powders entering the market for direct use in beverages, yoghurts, coffee and tea whitener, milk powders have seen a significant rise in popularity worldwide. The global market outlook is strong, with milk
powder valued at 34.6 billion US$ in 2023 and predicted to grow annually by 5.6 per cent, reaching 57.2 US$ billion by 2032.
GOING GREENER Sustainable production, processing, transportation and consumption of dairy products is essential to protecting the planet and achieving sustainability goals. It is also exported widely to developing economies where fresh milk is in limited supply. Aside from decreasing milk dumping, the
longer shelf life of milk powders means that less milk is wasted, helping reduce food waste and conserve resources. One of the most significant environmental benefits of milk powders for food manufacturers is its compactness and reduced weight. Around 225 litres of fresh milk is needed to
produce 3.75 litres of non-fat milk powder, meaning about 60 times less space is required to
thrown away and then having to be replaced is not just wasteful, it’s also unsustainable long term,” cautions Phil Brown. The ability to upgrade existing inspection equipment, designed with modularity and scalability in mind, contributes to a more sustainable industry.
LEADING BY EXAMPLE With the global milk powder market set to increase in value dramatically over the next 10 years, and with dairy farms targeting optimised productivity, further waste reduction efforts are not just necessary but imperative. Industrialisation of farming practices
combined with the rapid expansion of the global population, and its subsequent demands, has intensified the production of food and food safety pressures. As the world’s largest manufacturer and exporter of WMP and SMP, with their dairy farming predominantly pasture-based and underpinned by an ambitious ‘green revolution,’ New Zealand provides a strong model of sustainable, safe food processing. Fortress aims to leverage this localised
processing knowledge and best practices to respond to evolving food trends and the overarching need for sustainable production processes.
