Key takeaways:

  • Start where impact is highest: Electrification of low-temperature process heat and water reuse systems deliver the most immediate and scalable reductions in cost, emissions, and resource risk.
  • Prove and replicate: Designing small, right-sized pilots with clear performance thresholds and full instrumentation is the fastest route from “one-off success” to enterprise-wide transformation.
  • Learn from leaders: Companies from Kraft Heinz to PepsiCo are demonstrating how disciplined pilots, template replication, and smart financing can make sustainability practical and profitable.


Food and beverage manufacturers are under pressure to cut costs, reduce emissions, and future‑proof operations — without disrupting throughput or quality. The good news is the technologies to do this are mature enough to scale, especially for low‑temperature process heat, utilities, packaging, and water. What’s needed is a disciplined path from “great pilot” to “repeatable program.”

Let’s take a look at what to scale first, how to scale it, and who’s already doing it well.

Why act now (and where the biggest gains are)

Recent U.S. Department of Energy (DOE) analysis shows that six subsectors — grain and oilseed milling, sugar products, fruit and vegetable processing, dairy, animal processing, and beverages — represent 78% of food and beverage manufacturing emissions. In modeled net‑zero pathways, electrification and energy efficiency account for the largest reductions, while carbon capture, utilization, and storage (CCUS) plays a limited role in this sector due to dispersed, lower‑concentration point sources. 

In short, focus first on efficiency and low‑temperature process heat electrification, then fill remaining gaps with low‑carbon fuels.

For low‑ to medium‑temperature heat (<200 °C), industrial heat pumps are now 3-5x more energy‑efficient than traditional boilers (depending on temperature lift), making them prime candidates for pasteurization, CIP hot water, space heat, drying/evaporation with MVR, and bottle washing. 

When it comes to water reuse systems, a 2024 multi‑stakeholder paper under the U.S. National Water Reuse Action Plan highlights clear near‑term pathways for in‑plant water reuse (e.g., utility water, CIP pre‑rinse, cooling tower make‑up), recommending HACCP‑style risk assessments to streamline regulatory acceptance.

Where to start: The technology priorities that pay back

Among the many technologies in play, a few have emerged as particularly strong candidates for scale-up. 

Heat pumps and mechanical vapor recompression are increasingly being used to replace fossil-fuel-based boilers in processes such as pasteurization, cleaning-in-place, and evaporation:

  • Industrial heat pumps (IHPs) recover low‑grade waste heat from refrigeration or effluent and lift to 70-150 °C for hot water and some pasteurization needs. 
  • Mechanical vapor recompression (MVR) is highly effective for evaporation/concentration (dairy, fruit, sugar) and often synergistic with heat pumps. 
  • Electric boilers/e‑heaters are useful for backup/peaks and as transitional assets where grid contracts and tariffs are favorable.

Water reuse systems, particularly those combining membrane bioreactors with reverse osmosis and UV disinfection, allow companies to replace large volumes of incoming freshwater for utility applications such as cooling tower make-up or boiler feed. 

Anaerobic digestion, meanwhile, turns high-strength wastewater and organic residues into biogas that can offset purchased fuels. 

And across all these technologies, digital monitoring and controls provide the visibility needed to manage performance, optimize operations, and prove savings. The Department of Energy’s Better Plants partners report steady energy‑intensity improvements and billions in cumulative cost savings — evidence that metering, controls, and maintenance remain the cheapest decarbonization “fuel.” 

How companies of all sizes scale sustainability

Kraft Heinz announced plans to use up to $170 million in U.S. Department of Energy support to install technologies (heat pumps, electric boilers, solar, energy storage, etc.) across 10 U.S. plants. The project targets a greater than 99% reduction in annual emissions (relative to 2022 levels) while cutting energy use by 23%, slashing natural gas consumption by 97%, and trimming water use by 3%. Theirs serves as a model for template‑based replication.

Diageo invested more than €100M as part of a decarbonization plan at its St. James’s Gate (Dublin) site to eliminate fossil fuels from direct brewing operations (Guinness), combining grid electricity, heat pumps, and biogas generated from a new water recovery facility. The project is also targeting a 30% reduction in water use per brew by 2030. This is a strong example of heat electrification paired with circular water.

Nestlé announced an investment in the Stampede solar project in Texas — adding 326MWdc of solar energy, purchasing 100% of its renewable output, and reducing annual emissions by roughly 279,000 metric tons to help meet its goal of 100% renewable electricity by 2025. This shows how off‑site renewables can hedge electricity for electrified heat and plant operations.

PepsiCo reached its 2025 goal two years early and cited a 25% improvement in operational water‑use efficiency in high water‑risk areas, driven by technology upgrades and reuse. 

Bush Brothers & Company upgraded its process water reclamation facility at Dandridge, TN to reuse 300,000 gpd and cut utility water intake by 30% — an example of non‑product utility water reuse that reduces risk and cost.

Meister Cheese stabilized an on‑site anaerobic digester using nanobubble pretreatment, increasing biogas yield and avoiding major capex — demonstrating that waste‑to‑energy can scale for SMEs with the right pretreatment.

How to move from pilot to production

Scaling sustainability initiatives is not just about selecting the right equipment — it is about building a disciplined process. 

The first step is to establish a clear baseline of energy, water, and waste intensity at the facility level. With those benchmarks in place, leadership teams can set explicit thresholds that a technology must meet to graduate from pilot to full production. For instance, a heat pump trial might need to deliver a coefficient of performance above three, while a water reuse project might be required to displace at least 20% of freshwater intake with no quality or safety compromises.

Designing a “right-sized” pilot is equally important. Instead of attempting to electrify an entire steam system or recycle all plant effluent at once, successful projects often focus on a single loop, such as a hot water circuit or a cooling tower. Pilots should be instrumented to capture hourly data, not just averages, so teams can fully understand system dynamics and integrate them with production schedules.

Financing also plays a crucial role in scaling. Traditional capital budgeting can be supplemented with utility rebates, tax incentives, renewable power purchase agreements, or in some cases federal demonstration funding. Once a project proves successful, the final step is to document standard operating procedures, build operator training, and develop a template that can be replicated across other facilities. This repeatability is what turns one-off projects into enterprise-level transformation. 

“You can’t just focus on production alone. You need to consider the whole ecosystem of technical, financial, and operational factors at the same time.”

How to overcome barriers

Two of the most common challenges in scaling sustainability initiatives in food manufacturing are technical integration and risk perception. 

Electrified heat systems, for example, are sometimes seen as risky because of concerns about reliability or production downtime. The key is to treat integration as a controls project first and an equipment project second, ensuring that new systems are harmonized with plant automation. 

Water reuse can raise understandable concerns about safety, but a structured HACCP-style hazard assessment, combined with clear monitoring and corrective action protocols, has proven effective in building trust among regulators and quality teams.

A practical path forward

For leaders ready to act, next steps include: 

  1. Begin with a site-wide heat and water map, highlighting sinks, sources, and flows. 
  2. Select one promising electrification application and one water reuse opportunity. 
  3. Run engineering and financial analyses to establish viability, line up available incentives, and engage quality and environmental teams early in the process. 

By starting small, proving results, and then replicating the model across multiple sites, manufacturers can build momentum without overextending resources.

Scaling sustainable technologies in food manufacturing doesn’t require reinventing the wheel. By focusing on efficiency and electrification first, validating solutions through disciplined pilots, and replicating proven models, leaders can cut costs, lower emissions, and future-proof operations — all without compromising quality or throughput.

“Ultimately, it’s about presenting sustainability as a core enabler of long-term competitiveness.”
