Integrated Approach for Wastewater Treatment and Biofuel Production in Microalgae Biorefineries

The increasing world population generates huge amounts of wastewater as well as large energy demand. Additionally, fossil fuel’s combustion for energy production causes the emission of greenhouse gases (GHG) and other pollutants. Therefore, there is a strong need to find alternative green approaches for wastewater treatment and energy production. Microalgae biorefineries could represent an effective strategy to mitigate the above problems. Microalgae biorefineries are a sustainable alternative to conventional wastewater treatment processes, as they potentially allow wastewater to be treated at lower costs and with lower energy consumption. Furthermore, they provide an effective means to recover valuable compounds for biofuel production or other applications. This review focuses on the current scenario and future prospects of microalgae biorefineries aimed at combining wastewater treatment with biofuel production. First, the different microalgal cultivation systems are examined, and their main characteristics and limitations are discussed. Then, the technologies available for converting the biomass produced during wastewater treatment into biofuel are critically analyzed. Finally, current challenges and research directions for biofuel production and wastewater treatment through this approach are outlined.

“…Researches about preparation of carbonaceous materials from biomass are still mainly focused on three aspects: the improvement of base material, the properties of porous carbon, and the reduction of reaction temperature and pressures [15][16][17]. Because the metal ions randomly presented in the biomass could work as catalyst during the preparation process, which may cause poor reproducibility in terms of the morphology and properties of the resulted carbon.…”

“…However, the extract of sugary organic from biomass would increase the cost, more and more researches had been turned to study the direct use of natural resources for carbonaceous material preparation [21][22][23][24]. To lower the fabrication cost and avoid potential adverse environmental impact, great efforts have been devoted to the synthesis of carbonaceous materials from biomass in a sustainable approach, for example, under low temperature with sulfuric acid as the catalyst [15,23]. The pore size and architecture of the biomass derived carbonaceous materials could be adjusted via a hard template method.…”

In microbial fuel cells (MFCs), an important factor limiting practical applications is the high catalyst cost in cathode. Herein a rice husk-based porous carbon made through hydrolysis, activation and rolling was used as novel cathode. These porous carbons were characterized by SEM, XPS and BET analysis, and electrochemical measurements including linear sweep voltammetry and Tafel test were investigated. A maximum powder density (317.7 � 0.4 mW m À 2) on AC-KOH-1h with the largest BET surface area of 1809 m 2 g À 1 was obtained. This study revealed a fresh territory about the application of porous carbon produced by renewable resources for MFC electrode.
