Case Study: Salsicharia Estremocense

How a Portuguese Meat Processing Cuts Emissions and Costs with Renewable Energy and Smart Optimisation

 

A Salsicharia Estremocense, S.A. (SEL), headquartered in Estremoz, specialises in meat processing and charcuterie products. Founded in 1984, SEL is dedicated to the production of fresh and frozen meats, cured ham, and related products. The company promotes sustainability by improving energy efficiency, expanding the use of renewable energy, reducing emissions, and strengthening its commitment to sustainability.

A Commitment to Sustainable Growth

SEL pursues a long-term sustainability strategy focused on three primary objectives: reducing energy intensity, increasing renewable energy generation, and enhancing production system efficiency. This approach enables the company to achieve industrial growth while delivering measurable reductions in both energy consumption and CO₂ emissions.

Three Pillars of Sustainability:

1.
Industrial Energy Efficiency
Optimisation of refrigeration, compressed air, and thermal processes to drive down energy use
2.
Renewable Energy Expansion
Deployment of a 215.86 kWp photovoltaic system (UPAC) for on-site renewable self-consumption
3.
Emissions Reduction
Initiatives such as fleet optimisation, advanced energy monitoring, and process digitalisation to minimise operational emissions

SEL’s Decarbonisation Journey

283 MWh
SEL installed a 215.86 kWp photovoltaic array, generating roughly 283 MWh annually. This initiative reduces grid electricity purchases and prevents over 120 tonnes of CO₂ emissions each year
Heat
Plans are underway to install a heat recovery exchanger on the Boje compressor, with projected payback in under four months due to significant energy savings.
5 GWh
Identified as the highest-impact opportunity, SEL’s refrigeration improvements and heat recovery measures could save more than 5 GWh per year.

 

 

 

A Value Chain Approach to Sustainability

 

SEL’s commitment extends beyond direct energy savings, encompassing the entire value chain of industrial food production. By integrating large-scale photovoltaic self-consumption into its operations, SEL reduces dependency on the grid.

Simultaneously, the company is boosting efficiency in refrigeration, compressed air, lighting, and thermal systems, driving down resource use per tonne of product. Digital energy monitoring, predictive maintenance, and gradual fleet electrification are also part of SEL’s roadmap, providing greater control over energy use and enhancing long-term competitiveness.

In thermal processes, biomass boilers fueled by pellets, olive pits, and almond shells further reduce fossil fuel dependence.

Looking to the future, SEL plans to explore battery storage, advanced refrigeration optimisation, and trigeneration to push emissions and energy costs even lower. Through the REEValue initiative, SEL showcases how SMEs in the agri-food sector can align industrial growth with practical decarbonisation strategies and tangible improvements in energy performance.
