Summary: Microalgae are autotrophic microorganisms that create organic molecules through photosynthesis. The increased focus on renewable and algae-based bioenergy has led to the development of new integrated methodologies. Microalgae are being studied as a source of useful products, with the concept of an algal biorefinery gaining attention. This study explores the use of an algae-based bio-refining platform to produce energy, foodstuffs, and pharmaceutical goods, while also improving algae production efficiency.

Summary: The development of new biodegradable plastic materials from renewable sources is a major challenge for plastic industries to provide sustainable alternatives to petroleum plastic. This review focuses on summarizing the current state of bioplastic production, particularly on algal cellulose and its derivatives for bioplastic applications. Despite the potential of algae as a feedstock for nanocellulose, further research and optimization are needed in terms of cellulose content and downstream processing.

Summary: This study investigated efficient pH and dissolved CO2 conditions for indoor and outdoor cultivation of the BX1.5 strain of Parachlorella sp., a green alga that can produce valuable lipids and extracellular polysaccharides. The results showed that the BX1.5 strain can thrive in a wide range of initial pH and can produce valuable lipids under both indoor and outdoor culture conditions when supplied with 2.0% dissolved CO2. The acidic BG11 medium was found to effectively increase the biomass of extracellular polysaccharides during short-term outdoor cultivation.

Summary: This study investigates methane production from the co-digestion of sugarcane vinasse and distilled glycerol, finding that the highest methane yield is achieved at a 1:1 COD-based proportion. The addition of 30% and 50% glycerol increases methane production by 39% and 26% respectively compared to vinasse mono-digestion. On a biorefinery scale, the global energy potential for VGC is estimated to be 22% higher than VM, and extending VGC into the off-season could potentially double VM's bioenergy potential.

Summary: The researchers develop a unique dynamic programming framework to assess the value of investment in a multi-stage supply chain in the bioeconomy. They apply the framework to macroalgae farming and biorefinery processing, and the results indicate the viability of the sector built on traditional technologies. However, developing a new algae industry requires significant investment and depends on dynamic learning and prices.

Summary: The efficiency of microalgae cultivation on aqueous phase produced from (Co-)hydrothermal liquefaction of seaweed waste was evaluated. The highest bio-oil yield of 42.21% was obtained from HTL of microalgal biomass at 250 degrees C for 60 min. Aq-LP from microalgal biomass had the highest organic load, while that from seaweed residue had higher mineral ion content. Co-HTL enriched the Aq-LP with nutrients from both feedstocks, resulting in a 10.3% higher biomass yield.

Summary: A mathematical model is proposed to simulate the growth of microalgae from emissions in an outdoor airlift photobioreactor. The model takes into account the influence of total nitrogen, total phosphorus, CO2, temperature, and light intensity on biomass production. The model was tested under different experimental conditions with satisfactory results, making it useful for optimizing biomass production in other microalgae systems.
