The INNOVACC and Energy Efficiency of Catalonia (CEEC) clusters have successfully organized the seminar: “Use of renewable energies and reduction of emissions in the meat agri-food sector”.

This interesting online technical seminar on the use of renewable energies in the meat agri-food sector took place on 27 April. A total of 50 people connected to the day and were able to hear 5 case studies of companies that use these energies such as: photovoltaic solar energy, efficiency in thermal production rooms, energy with biogas, geothermal energy and energy with biomass and use of by-products.

The seminar was organized by INNOVACC and the Energy Efficient Cluster of Catalonia (CEEC), in collaboration with the FECIC.

The topic of this new technical seminar was chosen from the responses to a survey of all INNOVACC partners on topics of interest to be addressed by the meat sector.

The seminar began with the welcome of the three organizers, Francesc Ribera of the Efficient Energy Cluster of Catalonia (CEEC), Ignasi Pons (FECIC) and Eudald Casas (INNOVACC).

The first presentation was given by Jordi Coll from the company Energy Tools, who spoke about photovoltaic solar energy. He stressed that self-consumption of photovoltaics is already a mature technology with experienced installers, and with a favorable legal framework. He gave two examples of installations with very favorable real results. In the case of a food industry in Vic, they cover 25% of the electricity needed with photovoltaic panels. In the case of a farm in Navas, they cover 33% of the electricity needed with solar energy.

The second speaker was Antoni Mabras from Entropy, explaining efficiency in thermal production rooms. He graphically and schematically explained how to maximize the performance of a meat company’s heat and cold sources, and gave three practical examples of a bird slaughterhouse, a pig slaughterhouse, and a pig disposal room. In these cases, consumption savings in heat or cold production of 20-50% could be obtained.

Albert de Castellarnau from the company ESFOSA, explained the energy project with biogas in a pig slaughterhouse. He recalled that in Catalonia and Spain, very few biogas plants are built. In 2019 there were only 205 plants in the state out of a total of 17,240 plants across Europe. The company ESFOSA wants to help reverse this situation and plans to launch a biogas plant with co-management of sludge and meat waste for energy production (14 Mwh / d) and obtaining a solid final fertilizer .

Then, Jordi Espiell from the company Tellus, made his presentation on a practical case of geothermal energy. He explained different types of solutions for the use of geothermal heat pumps, for cold demand (climate and process), heat demand and DHW, with several possible combinations.

Finally, the fifth case study on biomass and the use of by-products was presented by Santi Alsina from the Avinyó slaughterhouse and Frederic Bigas from the Bigas Alsina company. The two speakers explained the installation carried out in the Avinyó slaughterhouse (PIGHEAT project) for the treatment and energy recovery of pig hair, by generating a dry waste of high calorific value that is used as fuel along with plant biomass. The plant is in operation at the company.

The seminar ended with a round table between speakers and attendees.
