“…Knowing the reasonable methanol-to-oil ratio influences the final amount of methyl ester yield that would be obtained. Thus, if the volume of the methanol-to-oil is insufficient for the transesterification reaction, the biodiesel yield will be negatively affected (decrease in biodiesel yield) because the glycerides will not be converted into fatty acid methyl esters [ 72 , 73 ]. This situation is likely due to the high mass ratio of reactants maximizing contact between the alcohol and the oil molecules [ 74 ].…”

“…The green process of extracting high-value chemicals from agriculture is one of the most successful methods for promoting global sustainable development. − The objective of this study was to extract pineapple peel polyphenols (PPPs) from pineapple peel waste and to use them as natural antibacterial agents. Based on the principles of cleaner production, we have achieved the zero-waste extraction of PPPs on an industrial scale using solvent recovery and concentration procedures.…”

Plant polyphenols' antibacterial capabilities are just beginning to be applied in the environment. In this study, solvent recovery and concentration techniques were used to achieve zero-waste extraction of pineapple peel polyphenol (PPP) powder on an industrial scale. For environmental sterilization, PPP antibacterial agents (PAAs) were created. Their physicochemical and antibacterial qualities were examined, and technical and financial analysis was done. The results showed that (1) among the major PPP components, protocatechuic acid content was the highest (48.90 mg/L), followed by quercetin dihydrate (17.56 mg/L); (2) PAA sprays passed the tests for physicochemical properties like pH and heat resistance; (3) at the 8 mg/mL concentration, PAA achieved 100% bacterial inhibition below 40 °C; and (4) the production cost of 8 mg/mL PAA spray was only $273.41/t at 100,000 t industrial scale. These findings might offer an application prospect in the development of renewable bacteriocins from fruit and vegetable waste materials.

“…This plant is identified as the best fiber yielding plant because of highquality fiber obtained from it for clothes making, which is the basic necessity of human beings. It has also some medicinal uses such as curing unspecified medicinal disorders, antiviral, anticancer, and antiulcer properties because of presence of omega-3 fatty acids (Ahmed et al, 2019;Kaithwas & Majumdar, 2010;Malik et al, 2018;Rozina et al, 2021;.…”

Utilization of renewable and alternative energy feedstocks such as nonedible seeds oil to deal with the increasing energy crises and related ecological concerns have gained the attention of researchers. Biodiesel is an efficient and renewable substitute for diesel engine. This work investigates the potential of inexpensive nonedible seed oil of Linum usitatissimum to synthesize biodiesel using iron sulfate green nanocatalyst through the process of transesterification. Flax seed contains about 37.5% oil content estimated through Soxhlet apparatus. Light microscopy revealed that seed size varies from 3.0 to 6.0 cm in length, 2.0 to 3.3 cm in width, and 0.7 to 1.0 mm in diameter. Color of seed varied from yellow to brown. Characterization of biodiesel is performed through GC–MS and FTIR. Scanning electron microscopy was carried out to study the morphological features of seed coat. Catalyst was characterized by scanning electron microscopy, energy diffraction X‐ray, and X‐ray diffraction. The diffraction peaks of Fe3O4 green nanoparticles were found to be in 2θ values, 30.24°, 35.62°, 38.26°, 49.56°, 57.12°, and 62.78°. Fuel properties of biodiesel are also determined and compared with ASTM standards. Linum usitatissimum biodiesel has density 0.8722 (15°C kg/L), kinetic viscosity 5.45 (40°C cSt), flash point (90°C), pour point (−13°C), cloud point (−9°C), sulfur (0.0432% wt), and total acid number (0.245 mg KOH/g). It is concluded that L. usitatissimum seed oil is a highly potential source for biodiesel production to cope with the challenge of present energy demand.
