However, other important measures remain to be implemented or reviewed, such as the taxation of the production and use of biogas, the complex and time-consuming administrative procedures for new biogas production and use facilities, or the review of the technical standards of the system. gas to reduce barriers to entry. According to AEAS data, there are today 2,232 treatment plants in the Spanish state that purify 4,216 cubic hectometers of water per year, producing just under a million tons of sludge, 41% of which come from the anaerobic digestion process, which involves in turn, a biogas production of 171,628,000 Nm3, that is, approximately 1030 GWh/year, of which 78% are used in the same sanitation facilities. The difference of 22% is the surplus that could be used with the expansion of existing facilities or the incorporation of new ones. Additionally, in the study of biogas production potential in the sanitation sector carried out in 2018 in collaboration with the IDAE, a potential of up to 1,880 GWh/year was detected, which would correspond to an increase in current production of 82% that could be used locally in our facilities or converted into biomethane for injection into the network, contributing to the objective of replacing 1% of natural gas in the network by 2030 according to the Biogas Roadmap, this 1% being an objective that It is known as conservative, estimating that around 10% can be achieved with the existing potential in Spanish territory.
Thus, biogas from WWTPs, which continues to enjoy good health in the urban sanitation sector, recognized and used for years by service operators, has opened new possibilities of use that will allow it to complement the existing ones within the sector. sanitation. Thus, Without a doubt, when we talk about biogas, there is a consensus that this renewable energy source has CZ Leads a promising future, but its success depends on expert and careful management of organic waste. By CAMILLE DEGARDIN 6623 readings AUTHOR CAMILLE DEGARDIN 11-29-2023 TAGS BIOMETHANE Methanation is a fundamental piece in the transition towards a more sustainable future, and a crucial part of the ecological transformation that our country requires. In this sense, the Ministry for the Ecological Transition and the Demographic Challenge has published the Biogas Roadmap, which has 43 lines of action to multiply the sustainable production of this gas of renewable origin by 3.8 until 2030. Without a doubt, when we talk about biogas, there is consensus that this renewable energy source has a promising future , but its success depends on expert and careful management of organic waste , which can only be provided by those who have a long history in this area.
Companies with experience in waste management provide essential knowledge and skills for the correct management of these resources in different parts of the process, such as collection and classification, optimization of anaerobic digestion processes, and the management and use of derived byproducts. of biogas production. Furthermore, the production plants of this renewable energy require comprehensive management that ranges from the supply of raw materials to the marketing of energy, including the design and operation of the facilities. For all this, it is key to have the necessary knowledge and know-how in all these areas. And treating this waste mostly entails a multitude of challenges, which I would like to exemplify through several specific cases. If we consider, for example, packaged biowaste, its recovery through methanization means being able to previously separate the products with a minimum of inappropriate waste so, on the one hand, as not to impact the proper functioning of the digester; On the other hand, guarantee the correct valorization of the digestate. In the case of municipal waste type FORS (organic fraction for separate collection), it almost systematically contains inappropriate waste such as bags or containers, and usually requires a depackaging stage to be able to be treated via methanation. In this way, the correct selection of the depackager becomes critical. For their part, certain biowaste can inhibit the reaction; For example, untreated glycerin, due to its high sulfur and/or salt content, needs to be stored to be subsequently introduced into the reactor in small quantities.
