“…The use of edible vegetable oils and animal fats for biodiesel production has traditionally been of high concern (Girotto et al 2015). There have been certain technological developments aiming to facilitate biodiesel production from the fat waste (Sodhi et al 2017) as this type of fuel is naturally derived from vegetable oil and animal fat hydrocarbons (Enweremadu and Mbarawa 2009). The two technologies, namely transesterification (Panadare and Rathod 2015) and hydrotreatment (Mayorga et al 2019), are recognised for their capability for processing fat waste into biofuels.…”

Among the current trends in waste management and circular economy is the involvement of new fractions of waste for sorting and collection. One of them is fats and cooking oils, especially those coming from households. Now, the nascent fat waste recycling becomes promoted as regulations and waste recovery targets have been set in the European Union. The traditional manner of discarding household fat waste usually causes sewage problems. However, utilisation of this waste brings the potential for contributing to the energy supply and material recovery. This research presents a mathematical model for the optimal location of fat waste bins and containers in the given municipalities. The container network should comprise as few containers as possible, while the walking distance for the citizens towards the container is as short as possible. The objective of the proposed optimisation model is to minimise the total number of collection points (infrastructure cost). The collection points represent the citizens' addresses in a municipality. The average walking distance towards a container is a novel feature in the model, which is pertinent to waste fractions with low production per person. Cluster analysis describes the variability between municipalities, and further, it is possible to use regression analysis to model the number of containers for any municipality or region. The proposed general decision support tool estimates the total cost and number of bins needed for any region or a country. The region from the Czech Republic, which was used as a study area, revealed the requirement for 609 containers, with only EUR 30,000 of investment cost. There are around 950 inhabitants assigned to a single collection point on average.

“…Waste cooking oils generated after the end of their edible life cycle are not fit for human consumption due to its degradation as a result of various chemical reactions such as hydrolysis, oxidation, chemical degradation, thermal decomposition and polymerization of the oil along with the augmentation of polar materials and the reduction of the unsaturated fatty acids during cooking process [15,16]. However, due to organic nature, renewable source and sustainable supply of WCO, it is a highly viable alternative to finite source and non-ecofriendly petroleum oils for developing different green products and additives for various industrial applications including the vibrant oil and gas industry of the world to explore and exploit oil and gas resources without any negative impact on the terrestrial, coastal and the marine environments and the ecosystems along with other non-hydrocarbon-based resources.…”

The environmental issues of mineral oil-based drilling muds and additives in spite of their excellent technical performance such as good lubricity and high wear protection characteristics and the technical issues of water-based drilling muds such as the poor lubricity and wear resistance characteristics in spite of their excellent environmental traits require the development of high performance water-based drilling muds to overcome the current as well as the future drilling engineering and other oil and gas field challenges. Hence, several value-added green products have been developed adopting the recycling and reusing aspect of green circular economy of waste cook oil (WCO) to develop eco-friendly fluid additives and demonstrate their applications to explore and exploit oil and gas resources without any damage to the terrestrial, coastal and the marine environments and the ecosystems. Analyses of technical performance of the WCO derived green products with respect to the equivalent commercial products indicate similar or superior technical performance with the added benefit of no environmental impact. Hence, the recycling and reusing of the WCO provide a sustainable circular economical route for ecofriendly product development to overcome the technical and the environmental challenges simultaneously. It also provides a potential avenue for the growth and development of local, regional, national and global industries and infrastructures, development and creation of new job opportunities for the local, regional and the global communities, especially in developing and under-developed countries to create a positive societal and economic impact. Although this paper highlights mainly the oil and gas industry applications, WCO has huge potential for other industrial applications to overcome the technical problems without any negative environmental consequences. It can be used as a sustainable raw material for the development of a large variety of value-added green chemicals and polymers such as plasticizers, binders, surfactants, eco-greases, biopolymers, etc for other industrial applications. The renewable, sustainable and locally available source of the raw material have high potential to bring long-term stability to the oil and gas field additive supply chain for continuous and uninterrupted drilling and production operation. The paper highlights the applications of several WCO-based value-added products to overcome the technical and environmental challenges faced by the oil and gas industry.

These resources are the primary source of increasing environmental pollution due to the emission of carbon dioxide from vehicular exhausts in addition to the greenhouse effect [2].…”

This study presents a green process to synthesize biodiesel using biosynthesized nano-catalyst and a novel methodology for analyzing the impact of influencing factors -methanol/oil ratio, the concentration of nano-catalyst, temperature, and time of reactions-on the yield of biodiesel obtained by heterogeneous nano-catalyst-based transesterification reaction. Nano-calcium oxide (nano-CaO) was obtained as a heterogeneous nano-catalyst using waste eggshells. Waste cooking oil was treated with methanol and nano-catalyst at varying methanol: oil ratios (4 -14:1), nano-catalyst concentration (0.5 -2 %), time of reaction (3 -4.5 hrs), and temperature (50 -65 • C). The superiority and effectiveness of the proposed transesterification indices were accomplished making use of Deluca and Termini fuzzy entropy weighted indexes to obtain optimal reaction conditions with 95.49 % biodiesel yield.
