Abstract

This study explores the growing field of biolubricants as sustainable alternatives to petroleum-based lubricants. This paper highlights the gap in the current literature regarding biolubricants from Waste Cooking Oil (WCO) using a mixed-methods approach of bibliometric analysis and systematic literature review (SLR). A bibliometric analysis was conducted using data from the Scopus database, covering 650 publications from 2000 to 2024. Furthermore, a systematic literature review provides a comprehensive analysis of the methods used for synthesizing biolubricants from WCO, particularly evaluating the types of catalysts and methods employed that influence the physicochemical properties. The findings show a significant increase in research activity from 2018 to 2022, with Malaysia and India leading in this area. Key research trends identified include catalysts, oxidation stability, and transesterification processes. Optimal conditions for biolubricant production from WCO were achieved using an Amberlyst catalyst at 81°C, yielding a 99% conversion rate. These results highlight the potential of WCO-derived biolubricants to support more sustainable industrial applications. This study is the first to combine bibliometric analysis and systematic literature review methods to provide a comprehensive overview of research on WCO-based biolubricant production. Through a systematic review of existing studies, this research provides a useful resource for industry professionals and renewable energy policymakers in their efforts.

Abstract

The growing volume of waste has encouraged the use of fuel derived from waste as an alternative energy source. However, its combustion releases flue gas containing harmful pollutants. This study assesses the effectiveness of a spray tower in reducing the opacity and temperature of flue gas generated from the combustion of a mixture of waste-based fuel and sawdust. Experiments used three fuel masses and three system setups: no sprayer, two sprayers, and four sprayers. Results showed that the spray tower reduced opacity from 33 per cent to about 15 per cent with two sprayers and 11.2 per cent with four sprayers. Gas temperature decreased from 65 degrees Celsius to 39 degrees and 35 degrees Celsius. A higher number of sprayers led to greater pollutant reduction. This technology shows promise as an environmentally friendly method for controlling emissions.

Abstract

The escalating accumulation of plastic waste demands not only scalable but integrative conversion solutions. Among thermochemical routes, catalytic pyrolysis has emerged as a promising pathway to produce gasoline-range hydrocarbons from plastic polymers compatible with spark-ignition engines. This review critically evaluates recent advancements in pyrolysis of key plastics polypropylene (PP), polyethylene (PE), polystyrene (PS), polyethylene terephthalate (PET), and polyvinyl chloride (PVC) with a focus on fuel yield, hydrocarbon distribution, and engine-level performance. Comparative analysis reveals PP as the most viable feedstock, achieving up to 85% liquid yield and producing oil with high Research Octane Numbers (RON 85–95), outperforming PE and PS in combustion efficiency and emission compliance. However, persistent challenges such as fuel instability, catalyst deactivation, and elevated aromatic emissions particularly from PS complicate real-world deployment. The review further dissects the interplay between catalyst type, reactor design, and post-treatment, highlighting how these variables modulate product quality and engine operability. Notably, 10–20% PP/PE-derived pyrolysis gasoline blends demonstrate near-parity with conventional gasoline in Brake Thermal Efficiency and regulated emissions, without requiring engine modifications. This work bridges molecular-level reaction chemistry with combustion diagnostics and policy-aligned emission metrics, offering a rare multiscale synthesis. By articulating process-emission-performance trade-offs, it provides a strategic reference for researchers and practitioners aiming to scale waste-to-fuel systems within circular economy frameworks.

Abstract

The chili farming center in Lubuk Cuik Village, Batu Bara Regency, is the second largest after Karo Regency, with a total area of 1,092 hectares. The challenges faced by members of the Berkah Abadi Jaya Cooperative include declining soil fertility, low productivity, and high fertilizer costs, affecting farmers' profits. To address these issues, training on compost production and cooperative management was provided. Initially, members were trained to make compost from agricultural waste (leaves) and animal manure (KOHE). These materials were sprayed with Yanysis technology to accelerate the composting process. Participants were also trained to operate compost shredders to reduce leaf size. Solid organic fertilizer (POP), made from a mixture of leaf compost, KOHE, and humus soil, was applied to a chili plot and compared to chemical fertilizers. The results showed that cooperative members were able to independently produce POP. The composting time was reduced from 1-3 months to 2 weeks, while the plant height, number of leaves, and chili fruits were similar. Additionally, cooperative members gained a good understanding of cooperative business management, decision-making, and business diversification.
