Special Issue Information
Dear Colleagues,
The blue economy emphasizes the sustainable use of ocean resources for economic growth, improved livelihoods, and ecosystem health. Within this context, the valorization of micro- and macroalgae presents significant potential. Microalgae, microscopic aquatic plants, and macroalgae, commonly known as seaweeds, are both rich in valuable compounds, such as proteins, lipids, carbohydrates, and bioactive substances. The use of innovative process strategies is essential to fully exploit the potential of these algae. Techniques like biorefining allow for the extraction and utilization of multiple products from algae, minimizing waste and maximizing value. Microalgae can be cultivated in photobioreactors to produce biofuels, pharmaceuticals, and nutraceuticals. They also play a role in wastewater treatment, absorbing nutrients and pollutants, thus contributing to environmental sustainability. Macroalgae, harvested from natural stocks or through aquaculture, offer their applications in food, cosmetics, and agriculture. Their high polysaccharide content makes them suitable for producing bio-based materials and bioplastics. Moreover, algae farming can enhance marine biodiversity and sequester carbon, aligning with climate change mitigation goals. In summary, integrating micro- and macroalgae into the blue economy through advanced process strategies can drive economic growth while fostering environmental stewardship and sustainability.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Bioengineering is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
