IN Brief:
- Premier Foods has reported new progress under its Enriching Life Plan sustainability strategy.
- The group invested £2.1m in a solar farm at Carlton Bakery and £3.3m in steam boiler upgrades at Worksop.
- The projects show how energy infrastructure is becoming a core manufacturing investment issue for food producers.
Premier Foods has reported further progress against its Enriching Life Plan, including low-carbon manufacturing investments across UK sites and a 14% reduction in Scope 1 and 2 market-based emissions during the year.
The group has completed a £2.1m investment in a new solar farm at its Carlton Bakery in South Yorkshire. The 2.9-hectare installation includes 3,500 solar panels and has the potential to supply nearly three quarters of the site’s electricity needs during peak production periods.
The Carlton project is expected to reduce site carbon emissions by approximately 468 tonnes per year while supporting long-term energy resilience and reducing annual energy costs. The bakery is a major production site for Premier Foods’ Mr Kipling brand and has operated as part of the local manufacturing base for more than 50 years.
At Worksop, the group has completed two major steam boiler upgrades at a site producing brands including Batchelors, Bisto, and OXO. The £3.3m investment is expected to improve energy efficiency and reduce carbon emissions by around 686 tonnes annually.
Heat recovery work at Lifton Creamery adds a further site-level element to the programme. Across the group, the projects sit within the Planet pillar of Premier Foods’ Enriching Life Plan, which was launched in 2021. The company said Scope 1 and 2 market-based emissions are now down 40% against its 2020/21 baseline.
The update also reported a 5% improvement in water efficiency and said 70% of key suppliers now have science-based decarbonisation targets in place. Alongside the manufacturing work, Premier Foods reported a 16% year-on-year increase in sales of non-HFSS branded products and said 50% of its products now meet a high nutritional standard and carry a registered health or nutrition benefit.
Factory infrastructure sits at the centre of the update. Food plants are energy-intensive environments, particularly where baking, cooking, steam generation, refrigeration, compressed air, cleaning, pumping, and packaging operate within the same production footprint. Energy projects therefore affect more than emissions reporting; they shape resilience, cost exposure, maintenance planning, and the ability to keep older assets productive.
Bakery provides a clear example. Ovens, mixers, cooling, proofing, packaging, lighting, and ancillary systems create a load profile that can benefit from on-site generation where production schedules align with peak solar availability. Solar does not remove the need for grid power or thermal energy, but it can reduce purchased electricity, lower exposure to price volatility, and support decarbonisation targets.
Boiler upgrades carry a different operational role. Steam remains essential across large parts of the food industry, including cooking, cleaning, sterilisation, heating, and process support. Replacing or upgrading boiler infrastructure can reduce fuel use, improve reliability, and create a stronger base for future heat transition work.
Heat recovery adds another layer by capturing energy that would otherwise be lost and redirecting it into useful process or building heat. The value of such systems depends on plant layout, temperature profiles, production schedules, maintenance discipline, and the ability to use recovered heat where it is needed most.
Food manufacturers are pursuing several routes into lower-carbon operations. Mars’ long-term renewable electricity agreement in Lithuania linked pet food production to new wind generation, while Premier Foods’ programme is built around direct site investment in solar generation, steam systems, and heat recovery. Both approaches are likely to remain part of the sector’s decarbonisation toolkit.
Energy efficiency also feeds directly into competitiveness. Labour, ingredients, packaging, logistics, and compliance costs remain under pressure, leaving manufacturers with limited room to absorb avoidable utility costs or downtime. Lower energy demand can support margin, but the larger benefit is often a more reliable factory estate with better controls, newer equipment, and clearer performance data.
The next phase of food manufacturing decarbonisation will be more difficult than the first round of visible projects. Solar installations, boiler upgrades, and heat recovery can deliver measurable gains, but deeper progress will require work on low-temperature heat, electrification, refrigerants, storage, demand response, and capital planning across mixed-age factories.
Premier Foods’ programme shows sustainability moving from corporate target-setting into plant engineering. Emissions can only fall as quickly as factories can modernise the energy systems that keep production running.
