dc.description.abstractStudies on the conversion of organic materials into biochar have been preferred due to the effectiveness of biochar. Aquatic ecosystems harbor a significant amount of organic biomass, much of which is transferred to terrestrial systems, but often remains as waste. In this study, Posidonia oceanica (PO), Halidrys siliquosa (HS), Ulva lactuca (UL), and Codium fragile (CF), commonly found as marine waste along coastlines globally, were used as feedstocks for biochar production under four different pyrolysis conditions. Several analyses were conducted to characterize both marine waste and biochar forms in order to evaluate their potential for agricultural applications. The results showed that marine wastes and biochars contain almost all the necessary nutrients required for plant nutrition in varying proportions. The CF feedstock has a higher nitrogen (N) content than other feedstocks, while the UL contains greater phosphorus (P), potassium (K), and magnesium (Mg). Additionally, the PO exhibits high calcium (Ca), boron (B), and manganese (Mn) contents. Carbon (C) content also varied significantly depending on the biochar production technique. Temperature had a greater influence than holding time on the disparities in the elemental composition of biochars. The pH values of all types of biochar increased with rising temperature. However, the electrical conductivity (EC) values of HS and PO biochars decreased with increasing temperature. The highest mean BET surface area was observed in PO biochars. However, UL biochar has the most significant proportional increase compared to the UL feedstock by 218 times. All characteristics determined for all materials (feedstock, biochar) were within acceptable limits for application to soil. In conclusion, both marine waste and biochar forms may be confidently used for agricultural purposes, particularly in soil applications, when considering the characterization parameters within the scope of this research. Additionally, supporting and developing these results with more comprehensive analysis and research would be more suitable to reveal the potential of these marine wastes for agricultural systems.
