We have replaced our old fuel oil boilers with biomass boilers. We have also managed to generate 10% of the energy we consume by using pig fur as fuel, which has substantially reduced the amount of waste of this by-product. In 2022, we've started the installation of a methanization plant to process waste produced by our industry.
This year, work has begun on an industrial scale methanation plant. This is the result of nine years of testing and trials, which have enabled us to improve and perfect the use of treated sludge generated by our company as a sustainable fuel source.
The plant will generate the necessary methane to substitute between 15 and 20% of the natural gas consumed yearly by the company, as well as 100% of the CO₂ used for animal stunning, significantly reducing the enterprise’s carbon footprint.
Further to this, the volume of sludge generated by the plant will reduce by 70%, while improving its properties as a natural fertilizer. In this way, a residue will be converted into a highly valuable organic fertilising resource for the purpose of sustainable agriculture.
In mid-2021, the biomass heater began operation, burning a combination of swine hair and wood chips. During the first months of use, we were able to reduce the annual consumption of natural gas at a rate of 7% in comparison to 2020, projecting a potential yearly reduction of 15%. This would mean an emission reduction of 497 tonnes of CO₂ per year.
Grup d’Avinyó installed the first industrial plant for the PigHeat project, together with the R&D&I department at Bigas Alsina, SA. This pioneering project mixes pig hair from our abattoir with woodchips to create a biofuel, thus cutting down on waste and generating part of the electricity used at the abattoir.
Catalana de Embutidos was awarded energy efficiency certification with support from the Spanish Institute for Energy Savings and Diversification, through the European Regional Development Fund.
We installed a pilot biomethanation plant at the company to test the lab results under more realistic conditions, a key step in moving from the laboratory to the industrial stage.
Grup d’Avinyó began laboratory tests to implement a biomethanation process to produce biogas from the company’s organic waste as part of a collaborative project with AINIA technology centre and Frontera Técnica. During this first stage, organic waste samples were tested to check their effectiveness at producing biogas through anaerobic digestion.
