Research, Cleaning Methodologies, Economic Valorization and Pilot Application for Macroalgal Blooms (MACRO CLEAN) project has published a Measurement and Research Methodology Guide focused on macroalgae, seawater, and sediment sampling, alongside innovative applications of macroalgae in fertilizer and bioplastic production.

This guide provides step-by-step methodologies to support researchers, policymakers, environmental organizations, and industry stakeholders working on sustainable marine resource management.

The publication presents an integrated framework that includes:

• Field studies and sampling techniques for macroalgae, seawater, and sediments
• Analytical methods for metal analysis and environmental assessment
• Greenhouse and plant growth trials using macroalgae-based fertilizers
• Production and testing of bioplastics derived from marine biomass

Special emphasis is placed on dominant Black Sea macroalgae species such as ulva sp. and cystoseira sp., highlighting their potential for economic valorization while addressing environmental challenges like eutrophication and macroalgal blooms.

Macroalgal blooms are a growing concern in the Black Sea region, driven largely by land based pollution and nutrient enrichment. This guide promotes:

• Methodological consistency across countries
• Comparable environmental data
• Sustainable alternatives to chemical fertilizers and fossil based plastics
• Knowledge sharing and capacity building among regional stakeholders

By turning an environmental challenge into an opportunity, the project methodology supports both ecosystem protection and sustainability.
