Pollutant Removal from Wastewater by Microalgae-Based Processes

Dear Colleagues,

Wastewater treatment is a pressing global challenge, with conventional methods often being energy-intensive and contributing to greenhouse gas emissions. Microalgae-based processes have emerged as a sustainable alternative, enabling the efficient removal of nutrients and organic and inorganic pollutants from various wastewater types, including municipal, industrial, and agricultural effluents.

Beyond pollutant removal, microalgae cultivation facilitates carbon dioxide sequestration and generates biomass that can be valorized into biofuels, biofertilizers, and other high-value products, aligning with circular economy principles. However, the optimization of cultivation conditions, scalability, and economic feasibility remain challenges in its application.

This Special Issue aims to showcase cutting-edge research on and developments in microalgae-based wastewater treatment systems. We invite contributions that explore innovative cultivation techniques, integration with existing treatment systems, and biomass valorization strategies. Studies focusing on microalgae–bacteria consortia, multi-omics approaches, and real-world applications are particularly welcome.

This collection will benefit researchers, engineers, policymakers, and industry stakeholders seeking sustainable and efficient wastewater management solutions. We welcome original research articles, comprehensive reviews, and case studies that advance the understanding and application of microalgae-based processes in pollutant removal from wastewater.

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 250 words) can be sent to the Editorial Office for assessment.

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. Clean Technologies is an international peer-reviewed open access quarterly 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 1600 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.
