Among various conversion technologies, pyrolysis stands out as one of the most efficient, converting biomass into solid, liquid, and gaseous products with high potential for energy applications. This study provides a comprehensive analysis of different pyrolysis methods in the context of macroalgae processing. It explores how operating parameters, such as temperature, heating rate, and residence time, influence the yield and quality of pyrolysis products, biochar, bio-oil and gas. The findings demonstrate that slow pyrolysis, conducted at lower temperatures and longer residence times, yields higher biochar, while fast pyrolysis, with higher temperatures and shorter residence times maximizes bio-oil production. Intermediate pyrolysis balances biochar and bio-oil outputs, whereas flash pyrolysis favors biofuel production with faster heating rates. Catalytic fast pyrolysis demonstrates strong potential for producing high-value hydrocarbons. Microwave-assisted pyrolysis of macroalgae produces significant syngas and bio-oil with high heating values and lower oxygen content. Additionally, co-pyrolysis with suitable co-feedstocks further enhances bio-oil properties. This study highlights the potential of macroalgae as a renewable resource, emphasizing the versatile applications of pyrolysis products. Harvesting macroalgae during the peak growth, optimizing pyrolysis parameters, integrating complementary techniques, and using efficient catalysts can significantly enhance conversion and yields.

This study evaluates the feasibility of using rice husk as an eco-friendly and cost-effective biosorbent for removing Mn(II) from contaminated water. A modified adsorbent, nitric acid-functionalized rice husk (NT-RH) was synthesized and characterized using SEM-EDX, PXRD, and FTIR techniques to assess its structural properties. The NT-RH exhibited a porous, macro-structured network that enhanced its adsorption capacity. Batch experiments examined key Mn(II) removal variables, including adsorbent dosage, temperature, contact time, and pH. The results demonstrated a maximum removal efficiency of Mn(II) of 94.96 % under optimal conditions, which included a manganese concentration of 50 ppm, an adsorbent mass of 0.6 g, a temperature of 25°C, a pH of 7, and a contact time of 60 minutes. The adsorption process was spontaneous and exothermic, with kinetics described by a pseudo-second-order model and isotherms best represented by the Freundlich model. Therefore, this research highlights the potential of rice husk as a sustainable material for removing Mn(II), effectively addressing the dual challenges of agricultural waste management and water purification.
