The consideration toward Waste Cooking Oils (WCOs) is changing from hazardous waste to valuable raw material for industrial application. During the last five years some innovative processes based on the employment of recycled WCO have appeared in the literature. In the present review article, the most recent applications of recycled Waste Cooking Oil are reported and discussed. These include the production of bio-plasticizers, the application of chemicals derived from WCOs as energy vectors, and the use of WCOs as solvent for pollutant agents.

“…Although the main biorefinery concept around WCO are focused on biodiesel, other valorization options have been exploited, including its use as raw material for the production of soaps, resins, polymers, grease lubricants and polyurethane (Abdulbari & Zuhan, 2018;F elix, Ara ujo, Pires & Sousa, 2017;Fernandes, Kirwan, Lehane, & Coles, 2017;Feng et al, 2018;Maotsela, Danha & Muzenda, 2019;Salleh, Tahir, & Mohamed, 2018;Sipaut et al, 2012;Suzuki, Botelho, Oliveira, & Franca, 2018;Zheng et al, 2018). WCO can also be used as a source for energy production, such as biohydrogen, pyrolytic oil, electricity (by direct combustion), hydrocarbons (by gasification and liquefaction) or blend to solid fuels Nanda et al, 2019;Panadare & Rathod, 2015;Rinc on et al, 2019;Rodrigues et al, 2018;Teixeira et al, 2018;Xiong et al, 2019;Xu et al, 2019).…”

Waste cooking oils (WCO) are vegetable oils discarded after food frying and great amounts are produced worldwide. Its management is a challenge, due to the environmental risk of illegally disposal into rivers and landfills. The main approaches for WCO valorization included their incorporation as component of animal feed and biodiesel manufacturing. Yet, the development of new feasible approaches is attractive from an economic and ecological standpoint. Due to their composition in triglycerides, untreated WCO can be used as feedstock for microbial growth (several species are able to use them as carbon source) and production of added-value compounds. In this way, microbial valorization of WCO is a sustainable biotechnological approach to upgrade a waste into a renewable feedstock for bio-based industry, favoring the circular economy concept. The objective of this review is to highlight the potential use of WCO in bioprocesses as an alternative to other physicochemical treatments. Firstly, an introduction to WCO problematic is presented, describing most common applications used currently. Then, an extensive review on the use of WCO by microorganisms is shown, focusing on bacterial and fungi species and its exploitation for bioprocesses development to produce metabolites of industrial interest, such as biopolymers, biosurfactants, lipases and microbial lipids. KEYWORDS Added-value compounds; microbial conversion; waste cooking oils 1. Waste cooking oils: General overview Waste cooking oils (WCO) are generated from vegetable oils (coconut, sunflower, soybean, palm tree, cottonseed, rapeseed, olive, etc.) employed to fry foods in household and HORECA (Hotels, Restaurants and Catering) segments and are no longer suitable for human consumption. Specifically, in HORECA sector, fast food restaurants (particularly those of chicken and

“…Over the past decade, evolving legislative restriction worldwide on ortho-phthalates that have been recognized potentially carcinogenic and endocrine-disrupting has stimulated great interest in bio-based alternatives that are renewable and display little or no adverse effects to human health. Of many bio-plasticizers, epoxidized fatty acid methyl esters (EFAMEs) are enjoying a surge of interest in PVC artificial material industry due to their high plasticizing efficiency [2], renewability [3,4], degradability [3,5], and low cost [3,6]. However, in comparison with ortho-phthalates and high-molecularweight epoxidized soybean oil, EFAMEs, usually obtained from unsaturated fatty acid methyl esters, tend to leach out from the PVC matrix [7], burdening the environment and shortening lifespan of the end-products.…”

Epoxidized methyl ricinoleate bio-plasticizer with a pendant acetate ester for PVC artificial material: circumventing existing limit on achievable migration resistance

et al. 2019

Processing polyvinyl chloride (PVC) artificial material requires plasticizer that softens the PVC coating. Currently, utilizing unsaturated fatty acid methyl esters to obtain epoxidized fatty acid methyl ester (EFAME) bio-plasticizers constitutes an environmentally responsible solution to substitute conventional ortho-phthalates that are endocrine disruptors or probable carcinogens. However, commercial EFAMEs, even with the highest epoxy value (ca. 5.5-5.8%) so far, still suffer from fast leaching from the PVC matrix, burdening the environment and shortening lifespan of the artificial material. Here, we report a proof-of-principle demonstration of a new strategy to obtain migration-resistant EFAME that harnesses the midchain hydroxyl of methyl ricinoleate and covalently attachment of a pendant acetate ester. Despite a low epoxy value (3.0%), the engineered bio-plasticizer displays significantly suppressed migration in multiple scenarios compared with one conventional EFAME with much higher epoxy value (5.8%). Circumventing the limit confronting previous strategy that highlights the sole contribution of epoxy value to achievable migration resistance, the rationale herein may provide guidance for designing new EFAMEs with comparable performance to ortho-phthalates, thus bringing the old and oft-maligned PVC artificial material industry one step closer to sustainability.
