On 11 December 2019, the European Commission (EC) announced the European Green Deal to transform the European Union (EU) into the first climate neutral region of the world. The European Green Deal provides an action plan to :(1) boost the efficient use of resources by moving to a clean and circular economy; (2) cut pollution and pressures on ecosystems (by decoupling economic growth from resource use); and (3) restore biodiversity by sustainably managing and preserving resources and ecosystems. The EU Green Deal builds on a series of sector and policy strategies that will support a just and inclusive ecological and climate transition. Building on a momentum set prior to the adoption of the Green Deal, increasing attention is given to the role marine ecosystems and the blue economy can play, and on opportunities they can provide as a source of resources.
In particular, major innovations are taking place in the field of Algae cultivation can contribute both macroalgae, traditionally harvested from wild stocks on European coasts and cultivated today at sea or inland, and microalgae produced in open ponds or closed systems such as photobioreactors or fermenters. Algae occupy today a production niche in Europe with significant potential in algae production and utilisation that remains to be seized for a wide range of applications including for human consumption and animal feed, biofertilizers , nutraceuticals, cosmetics, biomaterials and biofuel. Still many knowledge gaps remain on algae cultivation and utilisation, including:
A study: what for?
In this context, the European Commission has launched as study to provide sound and up-to-date knowledge on the potential impacts of scaling up the production of marine algae through aquaculture in the EU and its impacts. The main questions the study will address include:
How will the study be implemented?
The study builds on the collection of a wide range of technical, environmental and economic data related to different algae production technologies at different development stages (from pilot projects to large scale implementation in Europe and beyond). Information from the scientific and grey literature will be complemented by interviews with experts and stakeholders of the algae value chains – from its production to its final use in particular as a component of livestock feed. The evidence collected will be organised in a database and analysed for providing answers to the questions above, identifying key knowledge gaps requiring research beyond the scope of the present study.
The study will combine different scales of analysis: (a) collating and combining information for characterising individual algae production technologies; (b) analysing the potential for algae production in selected countries (namely: Denmark, France and the Netherlands) accounting for the availability of resources as well as possible regulatory, technical and economic constraints and solutions; (c) investigating the total potential algae production, its role in meeting animal’s feed requirements and its impact on GHG emissions at the European scale.
A stakeholder workshop will be organised within the frame of the study for sharing and discussing preliminary results and their policy implications. Feedbacks and input from workshop participants will contribute to the consolidation of the study’s algae knowledge base and of its final results.
The study has been launched in December 2021 and has a 12-month duration. It is implemented by ACTeon (France – coordinator), the universities of Arhus and Copenhagen (Denmark), and TNO (the Netherlands Organisation for Applied Scientific Research).
