“…The results of the analysis are presented in Table 6. The density of the oil was found to be 0.9646 gcm −3 , which is consistent with the values reported in previous studies such as [46] (0.921 gcm −3 ) and [47] (0.9119 gcm −3 ). Furthermore, the density value is close to the ASTM D 1298 normative value of 0.96 gcm −3 .…”

“…Furthermore, the density value is close to the ASTM D 1298 normative value of 0.96 gcm −3 . The viscosity of the oil was determined to be 50.9117 mm 2 s −1 , which agrees with the viscosity values reported in similar studies, that is, (42.2 mm 2 s −1 ) [47] and (50 mm 2 s −1 ) [48]. The amount of water present in the sample was found to be 0.15%.…”

The consumption of batteries and cooking oil have been increasing. Most used batteries are disposed of incorrectly, leading to health and environmental problems because of their composition. In a similar form, cooking oil, once used, is often released by the discharge reaching the wastewater, polluting soil, and water, which affects its treatment. In Ecuador, these environmental passives are recollected and stored without further treatment, which is a temporary and unsustainable solution. To address this issue, the circular economy concept has gained increasing attention. In this study, zinc oxide was prepared from discarded batteries using the hydrometallurgical method to use as a catalyst; it achieved 98.49% purity and 56.20% yield and 20.92% of particles presented a particle size of 1–10 nm. Furthermore, the catalyst morphology was investigated in an SEM, which showed that particle size ranged from 155.69 up to 490.15 nm and spherical shapes. Due to its characteristics, the obtained catalyst can be used in the industry instead of the zinc oxide obtained by mining processes. These processes are known to produce heavy contamination in the ecosystems and human health. Additionally, a zinc oxide lifecycle in the environment was analyzed through a material flow analysis (MFA), taking into consideration two paths, one assuming the disposal of used batteries and the other assuming the recycling of zinc. Biodiesel was produced with a heterogeneous catalyst. This took place with a transesterification reaction with used cooking oil, ethanol, and zinc oxide (ZnO) as catalysts. The biodiesel obtained had the following characteristics: 37.55 kJg−1 of heating power, 0.892 gcm−3 of density, 4.189 mm2/s of viscosity, 0.001% of water content, and a 70.91% yield. Furthermore, the energy consumption in biodiesel production was quantified, giving a total of 37.15 kWh. This kind of initiative prevents that waste from becoming environmental pollutants and potential health risks by giving them a second use as a resource. Moreover, turning waste into a valuable product makes the processes self-sustaining and attractive to be implemented.

Purpose: To analyze, at a laboratory level, the biodiesel production yield by transesterification of the vegetable oil extracted from weed species growing in local crop areas in Aguascalientes, México. Methodological Design: The study evaluated the biodiesel production yield by transesterification of the vegetable oil from the weed species Bidens ferulifolia (Jacq.) DC., Tithonia tubaeformis (Jacq.) Cass., and Bidens sambucifolia (Cav.). Their vegetable oil is extracted through an L9(34) design using alcohols and alkanes as solvents. Transesterification is conducted under an L4(23) design, employing NAOH and methanol as a catalyst and excess alcohol, respectively. Raman Spectroscopy and Fourier Transform Infrared Spectroscopy (FTIR) were used to characterize the biodiesel samples obtained. Results: In the FTIR and Raman spectra of the obtained biodiesel, peaks were observed at wavenumbers 1740 cm-1 and 1450 cm-1, respectively, corresponding to the C=O group of the conventional ester present in the fatty acid methyl esters of the biodiesel. This confirms that biodiesel was successfully produced from the studied weed species with production yields ranging between 10.3 and 15.3%. Research limitations: This is one of the first studies to provide information on the biodiesel production capacity of the selected weed species. Findings: Biodiesel was successfully produced through transesterifying vegetable oil extracted from the selected weed species. Further research is warranted to enhance biodiesel yields.
