The aim of present work was to bioremediate the waste cooking oil using a novel lipase produced in solid medium containing waste grease and wheat bran by Penicillium chrysogenum. Enzyme extracted with phosphate buffer was purified 10.6 and 26.28-fold after 90% ammonium sulfate precipitation and ion-exchange chromatography, respectively. The partial characterization of enzyme revealed its K(m) a...

Waste materials such as waste tire rubber (WTR), cooking oil (WCO), bio-oils, engine (WEO), and other oils have been the subject of various scientific studies in sustainable research field. The current environmental concerns identified to protect natural resources reuse materials. Accordingly, this work reviews use recycled mixed with (waste oil, oil) bio-oils that can be extracted from rejuven...

Converting waste cooking oil into biofuel represents a three-win solution, dealing simultaneously with food security, pollution, and energy security. In this paper, we encode the policy documents of waste cooking oil refining biofuel in China based on content analysis, and explore the related policies from the two dimensions as basic policy tools and enterprises supply chain. Research indicates...

One of the most concerned components in world’s food system challenges is waste, and it particularly a critical issue developed countries. Waste cooking oil (WCO) one liquid wastes that are recyclable. A proper recycling practice WCO helps to reduce adverse impact on environment can be reused by converting into industrial products such as biodiesel soap. With rising cost crude global market dep...

Near Infrared (NIR) spectroscopy was used for inline monitoring the enzymatic production of third-generation biodiesel from waste cooking oil (WCO) —with fatty acid profile similar to olive oil— under principles Continued Process Verification (CPV) and Analytical Technology (PAT). For this purpose, covalently immobilized mature Rhizopus oryzae lipase (rROL) transesterify WCO with methanol ethan...

An investigation was carried out to study the feasibility of using synthesized acid-bearing carbonaceous catalyst (SO 3 H–C and PO 4 H 2 –C) derived from cassava peel for biodiesel production waste cooking oil (WCO). The activity tested an autoclave type reactor three different alcohol ratios (1 : 3, 1 5 7) at four temperatures (50–80 °C) h. Two types (i.e. methanol (CH OH) ethanol C were used ...

The main disadvantage of biodiesel is its high price. The price of biodiesel depends on various factors such as the price of oil, methanol, catalyst, and labor. Among dif-ferent economic factors, oil accounts for the largest share of input costs of biodiesel production. In this study, first, suitable heterogeneous catalysts were identified for biodiesel production. Several studies were carried ...

In this work, the beads and powder potassium hydroxide (KOH) carbonate (K2CO3) supported on alumina oxide (Al2O3) were successfully prepared via incipient wetness impregnation technique. Herein, perforated hydrophilic materials (PHM) made from low-density polyethylene (LDPE) was used as catalyst reactor bed. The catalysts investigated using TGA, XRD, BET, SEM-EDX, TPD, FTIR while spent analyzed...

In search of a more sustainable society, humanity has been looking to reduce the environmental impacts caused by its various activities. The energy sector corresponds one most impactful activities since energies produced come from fossil fuels, such as oil and coal, which are finite resources. Moreover, their inherent processes convert into electricity emit pollutants, responsible for global wa...
