This dataset stems from the Joint Research Centre (JRC) Biomass Mandate (https://knowledge4policy.ec.europa.eu/projects-activities/jrc-biomass-mandate_en) and it is available for viewing and download on EMODnet web portal (Human Activities, https://emodnet.ec.europa.eu/en/human-activities) and on the platform from the European Commission’s Knowledge Centre for Bioeconomy (https://knowledge4policy.ec.europa.eu/visualisation/bioeconomy-different-countries_en#algae_prod_plants). The dataset provides information on the location (geographic coordinates and country) of the production facilities and their related info as the group of produced organism (macroalgae, microalgae and spirulina), the step in the value chain (Producer, Processor, Technology provider, Consultancy, Research and Development, Trader/Exporter) the production method (Fermenters, Harvesting , Photobioreactors, Open ponds, Semi Open ponds, land-based or at sea Aquaculture, Integrated multi-trophic or not) and the species farmed (see dataset). The data have been collected for the following countries: Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Faroe Islands, France, Germany, Greece, Greenland, Hungary, Iceland, Ireland, Italy, Latvia, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. The JRC, through a study commissioned for the Knowledge Centre for Bioeconomy in September 2022, has updated the database with the latest information and extended the scope to new socio-economic data, which are made available as a dataset collection (https://publications.jrc.ec.europa.eu/repository/handle/JRC129053) and an accompanying report (https://publications.jrc.ec.europa.eu/repository/handle/JRC130107). More detailed information on the Status of the Algae Producing Industry in Europe can be found in a scientific publication in Frontiers in Marine Science (https://publications.jrc.ec.europa.eu/repository/handle/JRC122250). All this work by the JRC aims at building a reliable database to characterize the algae sector and to support informed European policies on Blue Growth and Bioeconomy.
