“…This production method is thus more commonly used in the production of biomass for low-value applications, although some technical issues still need to be solved to unfold its potential in the upscaling of algae biomass production for uses such as biofuel (Prussi et al, 2011;Narala et al, 2016;Acién et al, 2017). The disadvantages of open cultivation systems are the increased risk of contamination, lower control of the environmental conditions and greater land and water requirements (Murthy, 2011;Mayers et al, 2016;Costa et al, 2019). Additionally, most of the European countries have sub-optimal climate conditions for large-scale outdoor microalgae production (Vigani et al, 2015).…”

Current Status of the Algae Production Industry in Europe: An Emerging Sector of the Blue Bioeconomy

The EU Bioeconomy Strategy aims to support the sustainable growth and development of the EU bio-based sectors while creating jobs, innovation and services. Despite the recognized potential of the algae biomass value chain, significant knowledge gaps still exist regarding the dimension, capability, organization and structure of the algae production in Europe. This study presents and analyses the results of a comprehensive mapping and detailed characterization of the algae production at the European scale, encompassing macroalgae, microalgae, and the cyanobacteria Spirulina. This work mapped 447 algae and Spirulina production units spread between 23 countries, which represents an important addition to the reported number of algae producing countries. More than 50% of these companies produce microalgae and/or Spirulina. Macroalgae production is still depending on harvesting from wild stocks (68% of the macroalgae producing units) but macroalgae aquaculture (land-based and at sea) is developing in several countries in Europe currently representing 32% of the macroalgae production units. France, Ireland, and Spain are the top 3 countries in number of macroalgae production units while Germany, Spain, and Italy stand for the top 3 for microalgae. Spirulina producers are predominantly located in France, Italy, Germany, and Spain. Algae and Spirulina biomass is directed primarily for food and food-related applications including the extraction of high-value products for food supplements and nutraceuticals. Algae production in Europe remains limited by a series of technological, regulatory and market-related barriers. Yet, the results of this study emphasize that the European algae sector has a considerable potential for sustainable development as long as the acknowledged economic, social and environmental challenges are addressed.

“…Closed photobioreactors were developed to overcome the abovementioned weaknesses (among others) of open pond systems, resulting in a series of reactor designs [39] which increased surface to volume ratio and system reliability [40]. An aseptic, low-cost and weather independent process is still a challenge, since closed systems costs are substantially higher than open pond systems [41] and thereby prohibitive depending on the target product.…”

Microalgae are aquatic unicellular microorganisms that can be found both in freshwater and marine systems; are capable of photosynthesis; and can grow as individual cells or associated in chains or small colonies. Microalgae cultivation has gained large momentum among researchers in the past decades due to their ability to produce value metabolites, remarkable photosynthetic efficiency, and versatile nature. The wide technological potential, and thus increasing amount of scattered knowledge, may become the very first barrier that a post graduating student, or any non-specialist reader, will face when introduced to the subject. In this review paper, we access the core aspects of microalgae technology, covering their main characteristics, and comprehensively presenting the main features of their various cultivation modes and biological activity from metabolites.
