“…Standard methods are developed by organizations such as the American Oil Chemists Society (AOCS), International Union of Pure and Applied Chemistry (IUPAC), and Japan Oil Chemists’ Society (JOCS) [ 15 , 26 , 27 ]. Among these methods, the titration method is the most common and the oldest FFA determination technique for VOs and UCO [ 15 , 26 , 28 ]. However, this method suffers from lower accuracy and relatively high solvent consumption, prompting the need for research into alternative methods, such as thermometric, calorimetric, electrochemical, spectroscopic, and chromatographic methods.…”

The quality of oil is highly dependent on its free fatty acid (FFA) content, especially due to increased restrictions on renewable fuels. As a result, there has been a growing interest in free fatty acid determination methods over the last few decades. While various standard methods are currently available, such as the American Oil Chemists Society (AOCS), International Union of Pure and Applied Chemistry (IUPAC), and Japan Oil Chemists’ Society (JOCS), to obtain accurate results, there is a pressing need to investigate a fast, accurate, feasible, and eco-friendly methodology for determining FFA in biological materials. This is owing to inadequate characteristics of the methods, such as solvent consumption and reproducibility, among others. This study aims to investigate FFA determination methods to identify suitable approaches and introduce a fresh perspective.

“…A growing concern pertains to the substantial ecological harm that sports can inflict [5]. For instance, major sporting events can exert significant pressure on the environment, depleting energy and resources while generating substantial food and beverage waste Collins et al [6]. The construction of sporting facilities, like golf courses, may also have adverse effects on surrounding vegetation and wildlife [5].…”

Aims: The main objective of the study was to determine how the consumers’ pro environmental concerns affected their green buying behavior in sports science and management undergraduate consumers. Furthermore, determining the green buying behavior of consumers and willing to pay for eco green products and awareness of the green products were also among the specific objectives of the study. Study design: This research is a quantitative investigation with a cross-sectional design, involving the collection of data at a single point in time. The primary objective of the study is hypothesis testing, specifically examining the association between individuals' pro-environmental concerns and their green purchasing behavior. The researchers had limited involvement in the data collection process, which relied on a questionnaire, and the study took place in a natural, non-contrived setting. The individual students served as the units of analysis for this study. Place and Duration of Study: The study's sample consisted of 140 Sports Science students from the Department of Sports Science within the Faculty of Applied Sciences at the University of Sri Jayewardenepura in Sri Lanka (n=140). Data collection occurred from June 2022 to September 2022. Methodology: The observed variables of the study were pro environmental concerns, consumers’ environmental concern, consumers’ health concerns, consumers’ economic concerns, consumer’s energy saving concerns and recycling concerns along with awareness of green products. A pre-tested Likert Scale questionnaire was used to accessed information and the validity and reliability was also measured. Results: The results indicate that consumers’ pro-environmental concerns significantly affect their green buying behavior. The environmental concerns, health concern, economic concerns, energy saving concerns and recycling concerns positively affected the green buying behavior. Also, it was found that consumers are willing to buy green products. The survey findings disclose that consumers’ awareness towards green products, high level of green buying behavior products and their pro environmental concern impacts their green buying behavior. Conclusion: Consumers are willing to buy green products. The survey findings disclose that consumers’ awareness towards green products, high level of green buying behavior products and their pro environmental concern impacts their green buying behavior.

Nowadays, the transformation of biomass into valuable chemicals and fuels through thermochemical, biochemical or even mixed technologies, is becoming increasingly popular and challenging. A promising solution for the near future is the substitution of non-renewable fossil fuels with a sustainable liquid feedstock for biofuel (biodiesel) production. The cost of conventional biodiesel production is higher than that of petroleum-based diesel production since it is produced mostly from expensive high-quality virgin oil. Conventionally, commercial biodiesel is produced via liquid base-catalyzed transesterification of triglycerides components of oil/fat with short-chain alcohols. It is that about 70–80% of the overall biodiesel production cost is associated with the cost of raw materials. Brown grease (with free fatty acid levels > 15%) is created from rendered trap waste and is known as Fats, Oils, and Greases (FOGs), it is a potential source of biodiesel feedstocks and is available at no cost. Many researchers are interested in using low-cost high Free Fatty Acid (FFA) oils as the feedstock for biodiesel production. This paper reviews the effect of feedstock pre-treatment and process parameters on the conversion of FOGs-wastewater to biodiesel by esterification-transesterification process.
