“…Furthermore, there are also sections with -OH bonds at wavelengths surpassing 3000 cm -1 [26]. The results of the regeneration process have retained only certain essential functional groups in SBE, including the silica matrix (exhibiting Si-O-Si stretching vibrations) at a wavelength of 1031 cm -1 and silica or quartz (displaying Si-O vibrations) at 795 cm -1 [22,27,28].…”

Nowadays, polymer as the raw material has been utilized in the development of Hollow Fibre (HF) membranes. PVDF is a commonly used for HF membrane material. However, it has hydrophobicity properties and lead membrane becomes low permeability and fouling. Therefore, to avoid these membranes problems, the incorporation of inorganic nanoparticles into PVDF membranes matrix is necessary to be applied for significantly improving PVDF membranes performance. This study investigates the characteristics and performance of PVDF-TiO2 HF membranes using spent bleaching earth (SBE) as a promising material from industrial waste as a renewable inorganic nanoparticle. This novel PVDF-TiO2-SBE HF membrane was fabricated using the subsequent steps: The preparation process incorporates SBE revival through solvent extraction and thermal treatment alongside the wet spinning technique for membrane fabrication. The Fourier transform infrared (FTIR) functional groups, scanning electron microscope (SEM) morphology, water contact angle and pure water flux performance were investigated to specifically understand the performance of this typical HF membranes. The IR results show that Si-O-Si groups were found in the membrane matrices due to the addition of SBE material. The addition of TiO2-SBE particles also indicate a sandwich (sponge-finger-like) morphological structure on the cross-sectional, a rough and porous surface structures. The hydrophilic properties of the HF membrane and pure water flux performance are determined by the composition of the TiO2-SBE mixture added as an additive material. The minimum contact angle found at 74.33°, while the water flux is 5.81 kg.m-2.h-1 on the identical HF membrane. Accordingly, this approach significantly enhances the properties of the pure PVDF HF membrane.

“…The first series of tests was made by adding 1 g of RSBE to 100 g of neutralized corn oil, the second series of bleaching test was made using thermal treated (RSBE) at different temperature. Then the mixture was stirred mechanically for 40 min heated to 100°C (Naser et al, 2021). Eventually, after mixing the RSBE and oil the separation was made by filtration.…”

The spent bleaching earth (SBE) from the edible oil refining industry was successfully regenerated through an extraction process using different organic solvents for removal of residual oil, followed by through heat treatment. The total percentage of extracted oil (PEO) for the solvents used showed the following order: PEO (Hexane) > PEO (Acetone) >PEO(Xylene) >PEO(MEK)>PEO (MIBK). The experimental results showed that regeneration by extraction process is insufficient to regenerate SBE, thus requiring also a high temperature treatment. In the current study, the effects of factors, such as liquid to solid ratio [1:1-5:1], temperature [20-40°C], and stirring time [30-60min] on the efficiency of extracted oil were investigated by maceration method. In order to determine the optimal condition, the Experience Planning Methodology (EPM) was adopted. To enhance the oil bleaching efficiency the regenerated SBE by solvent extraction was also treated at different temperatures (300°C – 500°C).

The demand for biodiesel worldwide is skyrocketing as the need to replace fossil diesel with renewable energy sources becomes increasingly pressing. In this context, biocatalysis is emerging as an environmentally friendly and highly efficient alternative to chemical catalysis. When combined with the utilization of waste materials, it has the potential to make the process of biodiesel production sustainable. In the study, the potential of an extract rich in lipase produced by an Amazonian endophytic fungus as a biocatalyst in the transesterification of waste cooking oil for biodiesel production has been systematically investigated. The fungus Endomelanconiopsis endophytica exhibited an enzyme production of 11,262 U/mL after 120 h of cultivation. The lipolytic extract demonstrated its highest catalytic activity at 40 °C and a pH of 5.5. Using soybean oil and frying residue as raw materials, biodiesel was produced through biocatalytic transesterification, and yields of 91% and 89% (wt.), respectively, were achieved. By evaluating the process parameters, a maximum biodiesel yield of 90% was achieved using ethanol at a ratio of 3:1 ratio within 120 min. The experimental results demonstrate the feasibility and sustainability of applying a fungal enzymatic extract as a biocatalyst in the production of ethyl esters using waste cooking oil as a raw material.
