Underlying the importance of energy costs in food production is the range of thermal processes demanding power. The energy to drive these processes is estimated to make up between 15% and 30% of their total production costs. This also means that the food sector is one of the largest contributors to global greenhouse gas emissions – making up about 26% of the world’s total.

Energy-intensive applications in the sector include pasteurisation, cooking, chilling, fermentation and cleaning – all of which are areas where energy efficiency improvements can have measurable carbon impacts.

Carbon emissions reduction has long been a strategic focus for food and beverage manufacturers, alongside their strict quality and cost targets. In this light, it is no surprise that system optimisation is now becoming more crucial than ever as a pathway to energy and cost efficiency.

Engineering decisions can have a direct impact on companies’ ability to meet sustainability goals, while also driving their operational competitiveness. Such decisions apply across functions, from thermal processing and cooling to water circulation and digital performance monitoring.

Energy intensive processes in food and beverage production

Food and beverage manufacturing relies on a range of energy intensive thermal and fluid processes that are essential for product safety, quality and consistency. These processes represent a significant proportion of total energy consumption within production facilities and are therefore key targets for efficiency improvements and carbon reduction strategies.

Typical energy intensive operations include pasteurisation, which requires controlled heating to eliminate harmful microorganisms while preserving product quality. Cooking processes also demand sustained thermal input to achieve required product characteristics and safety standards. In contrast, chilling systems are used to rapidly reduce product temperature for preservation and storage, often requiring continuous energy input to maintain low temperatures across production environments.

Fermentation processes, widely used in brewing, dairy and biotechnology applications, require tightly controlled environmental conditions, including temperature regulation, which contributes to ongoing energy demand. In addition, cleaning systems such as Clean-In-Place (CIP) operations are essential for hygiene and compliance, but also account for a significant portion of water heating and pumping energy use within food production facilities.

Together, these processes highlight the importance of system optimisation across thermal, cooling and cleaning operations, as even small efficiency improvements can translate into substantial reductions in both operating cost and carbon emissions.

“With energy costs making up a significant portion of production costs in food and beverage processing, rising tariffs are focusing producers on energy efficiency strategies to slow food price inflation.”

Improving process visibility in food manufacturing systems

As companies look for ways to improve energy and water use in their plants, they want to give operators greater visibility in terms of system performance – to enhance response times and keep processes streamlined.

Improved system visibility allows food manufacturers to identify inefficiencies in real time, optimise energy use and reduce unnecessary resource consumption. This is particularly important in continuous production environments where small inefficiencies can scale into significant operational and cost impacts over time.

Food and beverage production depends on precisely controlled thermal processes, particularly in sectors such as brewing, dairy, beverages and packaged foods. These environments rely on tightly regulated water circulation systems for heating, cooling and hygiene assurance.

In these kinds of applications, temperature control is critical to products’ final quality – with any deviation leading potentially to a whole batch of product needing to be reworked or even written off. Such risks translate directly into financial losses, reputational risk and increased resource consumption.

Optimised pumping systems, accurate temperature control and integrated monitoring therefore serve both sustainability and quality objectives simultaneously.

Sustainability strategies in food manufacturing

In terms of sustainability goals, the food and beverage sector is already at a mature stage and well advanced in its strategies. The large players in the industry are very much driven by sustainability outcomes, with shareholders and the general public wanting to see a steady reduction of their carbon footprint.  Achieving this goal often means that their suppliers are closely measured in their own environmental performance, even to the extent of including such requirements in their supply contracts.

For suppliers to effectively support their customers’ sustainability goals in the food and beverage market, they must understand the specific process context rather than supplying standardised equipment in isolation.

By understanding the customer’s processes, a solution can be provided that exactly matches what they are trying to achieve – so that the best efficiency and lowest carbon footprint can be delivered. This may involve standardised product platforms, but the integration and optimisation strategy can be tailored to each facility’s operational priorities.

While sustainability is an essential consideration in every project, cost competitiveness remains a decisive factor. Energy efficiency improvements typically translate into lower operating costs, but capital investment decisions must still demonstrate clear value.

Many suppliers may say they deliver efficiencies, but customers need to have these claims proven; a solid track record with good references, backed with clear operating data, is usually an essential starting point.

Digital optimisation and monitoring in food production systems

Perhaps one of the most significant developments in recent years has been the sector’s adoption of digital monitoring and optimisation platforms. These systems enable continuous performance tracking, predictive maintenance and transparent reporting of sustainability metrics.

“For suppliers to effectively support their customers’ sustainability goals in the food and beverage market, they must understand the specific process context rather than supplying standardised equipment in isolation.”

Solutions like Armstrong’s Envelope platform essentially offer food producers a digital optimisation and performance-management ecosystem. The value of these systems is that they can connect equipment, analytics and control technology – thereby improving energy efficiency, reliability and lifecycle performance.

Importantly, these digital solutions make system performance more easily visible to the customer, with integrated platforms that reduce instrumentation complexity. Some pump systems now even incorporate onboard displays and analytics that provide real-time performance data – eliminating the need for additional flow meters or sensors.

The adoption of digital optimisation platforms is also supporting more accurate ESG reporting by providing measurable, real-time data on energy consumption, water usage and system performance. This enables manufacturers to demonstrate progress towards sustainability targets with greater transparency and confidence.

Collaboration between technology providers and food manufacturers

This combination of optimisation and transparency helps customers align operational performance with environmental, social and governance (ESG) reporting requirements. Customers looking to reduce their energy consumption and lower their carbon footprint would therefore do well to look closely at their cold water systems, hot water systems and pressurised water systems.

“Optimised pumping systems, accurate temperature control and integrated monitoring therefore serve both sustainability and quality objectives simultaneously.”

As the scope for digital solutions grows, closer collaboration has therefore become necessary to ensure that innovations are put to work effectively. Food producers are increasingly preferring to work with technology providers who can partner with them in applying solutions that claim to reduce overall energy consumption.

System-wide optimisation is increasingly preferred over isolated equipment upgrades, as it enables manufacturers to achieve measurable energy savings across entire production processes rather than individual components.

In summary, then, the industry today looks beyond equipment-specific efficiency ratings, for instance, and rather seek system-wide optimisation that can be tracked and demonstrated. Technology partners must be equipped to design and apply system solutions that match customers’ process requirements – and which reduce energy consumption without compromising reliability and performance.
