Summary: Seven microalgae species were dried using four different drying methods, and biodiesel was produced from the dried microalgae. The highest vegetable oil yield and biodiesel yield were obtained in Schizochytrium dried by spray technique. The microwave drying method resulted in the lowest cloud point for Botryococcus braunii and the highest pour point and freezing point for Chlorella variabilis. Schizochytrium and Nitzschia were found to be the most suitable microalgae species for biodiesel production. Among the drying methods, spray drying produced the most successful results for biodiesel production from Schizochytrium.

Summary: The aim of this review was to explore the reasons why algae biodiesel is still not price competitive with fossil fuels despite significant investments in research and development. The study found that microalgal production accounts for a large proportion (84% to 93%) of the overall cost of biodiesel production, regardless of the technology used. The key factors impacting cost during mass cultivation were identified as light and oxygen concentration management, as well as overnight respiratory loss of oil. The review concluded that most of the research on microalgae biodiesel has been based on laboratory experiments with limited interdisciplinary overlap, resulting in economically over-optimistic assumptions.

Summary: Globally, large quantities of agro-industrial wastes are generated annually in various industries, including milling, brewing, agriculture, and food. These wastes can be converted into valuable biochemicals/bioactive compounds. Pineapple by-products, which account for 60% of the fruit's weight, are currently disposed of as waste, leading to disposal and pollution issues. However, these by-products can be utilized for the production of biochemicals/bioactive compounds rich in cellulose and hemicellulose. This proposed review article focuses on waste-free approaches that add value, including innovative biorefinery techniques and microbial fermentation.
