Interest in environmentally friendly and renewable energy, such as biodiesel, has grown significantly over fossil fuels. Biodiesel is a promising fuel alternative to petroleum diesel because it offers economic and ecological benefits. It is produced from the transesterification or esterification of suitable oil feedstocks and catalysts. Commercial homogeneous catalysts face numerous obstacles, including product separation and soap formation due to the interaction between high-FFA feedstock with homogeneous base catalysts. Thus, biochar-based magnetic heterogeneous catalysts in biodiesel production have received attention from researchers due to their simple separation process, large surface area, and faster catalyst recovery. In addition, many researchers have explored using cosolvents with heterogeneous catalysts to enhance biodiesel yield by minimizing the phase resistance between oil and alcohol. This review investigates recent improvements in biochar-magnetic bifunctional heterogeneous catalysts for biodiesel production, focusing on their ability to integrate esterification and transesterification reactions in a single step. The influence of oil feedstock properties, cosolvents, and catalyst preparation methods on biodiesel yield is thoroughly examined. Furthermore, the role of biochar derived from waste materials in improving the performance of magnetic solid-acid and base catalysts is extensively investigated.

This study attempts to upcycle jojoba oil cake to produce alternative proteins by investigating its extractability, and physicochemical, and functional characteristics. Three different extraction methods, namely, hot-pressed, dehulled and hot-pressed, and cold-pressed, were adopted. The results showed a significant impact of the pressing techniques on the properties of jojoba protein.

Hot pressing methods resulted in protein dissociation, denaturation (T<sub>d</sub>: 79.9 °C), and disintegration, leading to the loss of structural integrity, which was evident from the SEM images. Conversely, the cold-pressed proteins exhibited high thermal stability (T<sub>d</sub>: 87.4 °C), bioactivity (73.63 % DPPH free radical scavenging activity), and functional properties despite having comparatively lower purity (61.53 %). The supremacy is attributable to the structural integrity of the proteins, which is preserved due to minimal processing impact.
