Waste cooking oils (WCOs) are the used oils that are not edible and usually discarded illegally by households and restaurants, food frying and food processing facilities, catering industries, etc after the end of their edible life cycle. Even, though WCOs are ecofriendly, biodegradable and virtually non-toxic, disposal of huge amount of WCOs in the sinks, drainage systems, canals, rivers, water ways, ecosystems, landfills, etc can cause numerous ecological, environmental and municipal problems due to the oxygen and light depletion effect on aquatic lives, blockage of drainage and waterways and the eutrophication effect of excessive minerals and nutrients of the disposal or accumulates sites. Eutrophication is the result of high nutrient-induced increase in phytoplankton productivity, micro-organisms heightening and algal growth in waterways, landfills, drainage systems, marshes, canals, lakes, water reserves, etc. Hence, recycling and reusing of WCO for development of various green additives and value-added products for different industrial applications could solve the illegal disposal problems and associated environmental issues of WCOs. Moreover, the synthesis and development of green additives will safeguard the global environments and ecosystems by providing a sustainable source of ecofriendly additives for various industrial applications. This paper describes the synthesis, development and formulation of several green additives and products by recycling the WCOs for reusing for oil and gas industry applications to explore and exploit hydrocarbon resources without any damage and degradation to terrestrial, coastal and marine environments, eco-systems and non-hydrocarbon resources. The green products and additives were developed by physical pretreatment and transesterification of waste cooking oils using methanol and a basic catalyst. The developed products are ecofriendly lubricants for waterbased muds, a base fluid for Eco-OBM formulation and an ecofriendly spotting fluid to rescue a stuck pipe in case of a pipe sticking event while drilling. Experimental results of the WBM (water-based mud) lubricants indicate excellent lubrication potential to enhance the water-based mud lubricity and reduce the coefficient of friction (COF). The ecofriendly base fluid developed by transesterification of WCO has rheological profile and plastic viscosity similar to mineral oil-based base-stocks and thus demonstrates its suitability for an Eco-OBM development to safeguard the global environment. An ecofriendly spotting fluid developed using the WCO-based feedstock also showed superior debonding of adhesive bonds created between the metal surface of a spherical foot embedded into a mud cake and thus demonstrated its potential to provide higher ease of recovery of a stuck pipe in a real borehole environment compared to a traditional spotting fluid used for comparative assessment of the debonding performance of spotting fluids. The results clearly demonstrate the potential of recycling and reusing of WCOs for various green additives and products development for different industrial applications including the vibrant oil and gas industry to meet the global energy demand without any detrimental impact on terrestrial, coastal and marine environments and ecosystems.
