Abstract

Oily waste is one of the most difficult types of waste to manage due to the lack of filtration facilities for petrochemical industry waste. According to the Ministry of Environment and Forestry, the average amount of oil is 1000-2000 mg/L in industrial liquid waste, which has a negative impact on the aquatic environment and other biota. On the other hand, in 2020, tobacco consumption reached 322 billion sticks, producing approximately 107.3 tons of cigarette butt waste. Cigarette butts contain cellulose acetate, making them solid waste that is difficult to decompose naturally. However, cigarette butt filters, which are rich in cellulose acetate, have great potential as an alternative raw material for membrane technology. This study aims to develop polymer membranes based on recycled cigarette butt waste as an environmentally friendly membrane system for sustainable living, by evaluating the effectiveness of water filtration using these membranes with a minimum permeation flux indicator of 400 L/m²·hour and reducing membrane production costs by ≤ 30% compared to conventional membranes. The method used is descriptive with a quantitative approach, focusing on the utilization of cigarette butt waste as a polymer membrane. Data collection was carried out through experiments, observations, and literature studies. From the tests conducted, the permeation flux test was 474,6-588,5 L/m²/hour, referring to Widiasa’s (2014) research. The water toxicity test with a pH of 7 met SNI 06-6989.11-2004, and the durability test showed that the membrane could be used three times.

Review

This paper presents an intriguing and highly relevant study addressing two significant environmental challenges: the persistent problem of oily industrial wastewater and the overwhelming accumulation of cigarette butt waste. The authors propose an innovative solution by utilizing cellulose acetate-rich cigarette butt filters as a raw material for developing polymer membranes. This approach offers a compelling example of circular economy principles, transforming a difficult-to-decompose waste product into a valuable resource for environmental remediation, thus aligning well with the goal of developing sustainable and environmentally friendly membrane systems. The research employs a descriptive quantitative approach, utilizing experimental data, observations, and literature studies to evaluate the effectiveness of these novel membranes. The abstract highlights several promising preliminary results. Notably, the developed membranes achieved an impressive permeation flux of 474.6-588.5 L/m²/hour, successfully exceeding the target indicator of 400 L/m²·hour. Furthermore, the treated water exhibited a neutral pH of 7, reported to meet the specified SNI 06-6989.11-2004 standard for water toxicity. These findings suggest the membrane's potential in delivering efficient water filtration performance, which is a critical step towards addressing industrial wastewater challenges. While the initial results are encouraging and demonstrate the viability of using cigarette butt waste for membrane fabrication, the abstract leaves several critical aspects for deeper investigation. For instance, the stated durability of the membrane, usable only "three times," is a significant limitation for industrial application and warrants extensive optimization and long-term performance evaluation. Crucially, the abstract focuses on permeation flux and general water toxicity but does not explicitly detail the membrane's efficiency in *preventing oil-water emulsion* or its *oil removal capabilities*, which is the primary objective implied by the title. Additionally, while cost reduction by "≤ 30%" is a stated aim, no quantitative results regarding actual production cost savings are presented. Future work should prioritize comprehensive oil separation efficiency tests, rigorous long-term durability studies, and a detailed economic analysis to fully assess the commercial viability and full impact of this promising technology. Despite these points, the study offers a valuable contribution to sustainable materials science and waste valorization.
