Development and implementation of environmentally safe biotechnologies for the utilization of aquatic organisms biomass

Abstract

Human-induced water nutrient enrichment, termed "cultural eutrophication", spurs algae proliferation. This study proposes removing excess cyanobacterial biomass, or blue-green algae, for biofuel production. The resultant digestate serves as organic and mineral fertilizer. Investigating bio-methanogenesis, the study examines reactions for biogas production from BGA, analyzing its chemical and physical properties. This eco-friendly approach, utilizing excess organic matter from algal blooms, ensures sustainable resource utilization. The viability of utilizing cyanobacterial biomass underscores its ecological and economic importance. This paper establishes safe cyanobacterial biomass processing principles, offering a comprehensive technological framework for methane and fertilizer production from various substrates. © 2024 Trans Tech Publications Ltd, All Rights Reserved.
