60% of the waste it generates is destined to the generation of a synthesis gas, and the remaining 40% to compost
The experimental sludge treatment plant at the San Javier treatment plant has received an award for its contribution to the circular economy. The infrastructure has been chosen by the European network INtercamBIOM as the best innovative practice with biomass in 2022.
The first prize, shared with another waste management project, has been awarded by the European network belonging to the Branches project, implemented in parallel in Spain, Italy, Germany, Poland and Finland, the Autonomous Community reported yesterday. Its objective is to increase the adoption of new technologies and innovative practices in obtaining, managing, transforming and using biomass for energy purposes, and other value-added uses.
The San Javier plant provides a technologically and environmentally sustainable solution to the sludge extracted in the wastewater treatment process. About 60% of the waste, separated during purification, is used to generate a synthesis gas (singas), and the remaining 40% to improve the quality of the soil for crops or for the production of compost, among other uses.
This system contributes to environmental sustainability and the circular economy, since electrical and thermal energy is produced from the gas generated, which is used in the self-supply of the treatment plants themselves, reducing the consumption of traditional energies and the carbon footprint.
In addition, the ashes resulting from the sludge heating process will be used to enrich the soil for crops, adding these additional nutrients, thus reducing the use of chemical fertilizers for agriculture.
