Quality variations of leachate resulting from cigarette filter recycling as a challenge for its management

Recycling is known as a solution for cigarette filter management, but this may cause the release of trapped pollutants in it. Cigarette smoke toxins and chemicals that trapped in the cigarette filter can accumulate in the recycling leachate. In this study, littered cigarette filters and freshly smoked cigarette filters were recycled and the resulting leachate was analyzed. The results showed that the minimum and maximum Chemical Oxygen Demand (COD) of the studied leachates were 2100 mg/L and 11,300 mg/L, respectively. The maximum temporal variation in the studied leachate quality was 74.28%, but the maximum spatial variation was 314.2%. COD in the freshly smoked sample was 2600–9200 mg/L more than the littered samples. The average concentration of chromium, lead, nickel, and cadmium in littered samples was 0.023, 0.024, 0.045, and 0.019 mg/L, respectively. Environmental conditions such as humidity, the efficiency of the urban cleaning system in reducing the resistance of littered filters, the difference in the quality of the filter and tobacco, and the difference in smoking behaviors were effective in this variation. Reducing the toxicity of cigarette smoke and improving the efficiency of the urban cleaning system can lead to the same quality, but leachate treatment is necessary to reduce the environmental risk.

Acute effects of charcoal filters and package color on cigarette perceptions and use behaviors: Results from a randomized pilot study examining Natural American Spirit “Sky”

IntroductionCharcoal-filtered cigarettes have been available for decades but have never held a major share of the U.S. cigarette market. This pilot study gathered initial behavioral data characterizing how “Sky”—a recently introduced charcoal-filtered cigarette variety that uses potentially misleading marketing features—is used and what impact its packaging color has on consumer perceptions. MethodsForty adult daily non-menthol cigarettes users (52.5% male, 75.0% White, mean age = 46.1, 14.3 mean cigarettes/day) completed a single-session deception study utilizing a 2 ×2 mixed factorial design to manipulate cigarette filter condition (charcoal vs. non-charcoal) and pack color (light vs. dark). Participants smoked two cigarettes identical in appearance and packaging but differing in filter type (blinded and order counterbalanced) and completed pre- and post-cigarette CO samples and post-cigarette questionnaires. ResultsParticipants endorsed more favorable subjective ratings, puffed less of, held more correct beliefs about risks, and expressed greater intentions to use the charcoal (vs. non-charcoal)-filtered cigarette (p’s <0.05). Pack color had few effects on outcomes; however, cigarettes in light vs. dark colored packs were rated as cleaner tasting (p <0.01). Neither filter condition nor pack color affected CO boost. There were no interaction effects on any outcomes. ConclusionsUnder blinded conditions, Sky charcoal-filtered cigarettes are initially appealing independent of their packaging color. Findings warrant further study of these effects on perceptions, behavior, and harm exposure after longer, open-label use periods. Findings may inform regulatory decisions regarding cigarette packaging and filter composition.

Production of solid acid catalyst using waste cigarette filters for esterification.

Cigarette filters were utilized as carbon source for the production of solid carbon acid catalysts. In this study, the process of carbonization and simultaneous sulfonation via hydrothermal treatment was employed. The catalysts were prepared by mixing cigarette filters and sulfuric acid at temperatures of 100, 150, and 190°C for durations ranging from 2 to 8h. It was observed that the highest conversion of oleic acid occurred when the catalyst was synthesized at 190°C for 4h. The optimized conditions for the esterification reaction using this catalyst included an oleic acid to methanol molar ratio of 1:12, a catalyst loading of 5wt%, and a temperature of 100°C for 1h. Additionally, the catalyst was successfully reused four times without significantly impacting the reaction yield. These findings highlight a promising approach for the utilization of waste materials, with immediate implications for waste management practices and positive environmental impacts.

Toxic effects of tobacco on soil worms in densely populated cities

Soil contamination by cigarette butts has become a serious problem in recent years. The culture of earthworms Eisenia foetida (Sav, 1826) has been used in this scientific work as an object for research. The toxic effects of tobacco were investigated during vermicomposting of cigarette butts. Analysis of changes in the age structure of the population showed that the most resistant to the action of toxic units are sexually mature individuals and juveniles. Larvae and juveniles are most sensitive to soil contamination by cigarette butts. The tested earthworm populations under the influence of experimental drawings lost the productivity of their cocoons. Thus, regular dropping of cigarette butts on the soil surface leads to gradual destruction of earthworms in urban soil.

Assessment of marine litter on Morocco’s Mediterranean beaches

Marine litter pollution is one of the world’s major environmental challenges. In the Mediterranean, marine litter on beaches is mainly generated by tourism and recreational activities. The present study is part of an "Adopt-a-Beach" pilot project, initiated as part of the Marine Litter MED (ML MED) project, coordinated by the United Nations Environment Programme UNEP/MAP. The main objective of this work was to assess and quantify marine litter on four beaches along Morocco’s Mediterranean coast (Merkala Tanger, Amsa Tetouan, Sabadia Al Hoceima, and Miami Nador) over a seasonal cycle during 2018–2019, in line with UNEP/MAP guidelines. On average, 1768 items/100 m were collected from the four beaches, with a density of 0.34 items/m2. "Plastic/polystyrene" was the main component of the total debris collected, accounting for 74.1% in number of items, followed by "paper/cardboard" at 6.4%. The dominant categories of top 10 items were "plastic/polystyrene pieces &lt; 50 cm" (G76), "cigarette butts and filters" (G27), "plastic caps and lids" (G21/24), and "crisps packets/sweets wrappers" (G30/31) that all comprised 49.9% of the total items. Tourism and recreational wastes were the most represented sources at 52%.

A preliminary investigation of associated chemicals in cigarette butt waste from the tourist beach area of North Jakarta, Indonesia

Cigarette butts are among the most common and problematic forms of marine litter. However, there is limited research on the occurrence, abundance, and potential chemicals associated with cigarette butt waste in the environment. The study focused on investigating the occurrence, abundance, and chemical composition of cigarette butt waste on Ancol Beach, Jakarta, Indonesia, addressing a gap in knowledge regarding this prevalent and problematic form of marine litter. Despite Ancol Beach’s regular cleaning efforts, cigarette butt waste was still widespread with an abundance of 1.136 pcs/m2. However, this cigarette butt waste number is still less abundant compared to other regions. Chemical analysis of the cigarette butt waste revealed the presence of various chemical groups, notably aliphatic hydrocarbon compounds. The study emphasizes the importance of understanding and mitigating the environmental repercussions of the chemicals associated with cigarette butt waste and microplastic particles on the coastal ecosystem. Further research is urged to delve deeper into the emerging chemical pollutants present in cigarette butt waste spread in the coastal environments.

¿Se cumple la ley de control del tabaquismo en las terrazas de hostelería?

To describe tobacco consumption and the compliance with the law on hospitality terraces in Barcelona. Cross-sectional study by observation in a sample of 120 hospitality terraces in Barcelona. 30-minute observations were made using a standardized record sheet. The study variables were number of people smoking, number of cigarettes smoked, cigarette butts, socioeconomic status of the neighborhood, time of observation, consumption regulation, number of chairs and number of persons. There were people smoking at the time of the observation in 97.5% of the terraces, with no differences according to socioeconomic level of the neighborhood or the regulation of the terrace. There was no compliance with the law in 100% of the terraces where smoking was banned. The widespread non-compliance with the current law indicates the need to implement a smoking ban without exceptions on hospitality terraces.

Thermo-chemical conversion of cigarette butt filters waste through pyrolysis process using thermal analysis techniques

Thermo-chemical conversion of cigarette butt filters (CBF) waste was investigated using various thermal analysis techniques (simultaneous TG-DTG-DTA and DSC methods) at different heating rates in an inert atmosphere. Thermo- and thermo-physical properties of waste material were discussed, from the point of view of chemical structure and the influence of experimental parameters on the conversion process. It was established that acetyl groups of plasticizer (triacetin) interact with cellulose acetate through dipolar interactions and hydrogen bonding?s. Influence of these polar interactions can affect the position of glass transition temperature, Tg, of CBF. Based on estimated value of Tg from DSC analysis, it was found that cellulose acetate present in CBF has degree of substitution equals to 2.8, where the presence of cellulose triacetate was confirmed. It was assumed that an increase of degree of substitution leads to decline in the crystallinity. A decline of crystallinity causes the reduction of hydroxyl groups, leading to less organized chains, and whereby decreasing of inter-molecular interactions through hydrogen bonding. Based on the examination of thermophysical characteristics of the tested material, it was found that both, the heat capacity and the thermal inertia of material linearly increase with temperature, during pyrolysis progression. It was concluded that the type of bio-char produced in this process would have a large capacity to store the heat, which may depend on the formed particles size diameter and porosity. Furthermore, it was inferred that magnitude drops of thermal conductivity, ?, after Tg depends on the material fibrillation.

Cigarette filter butts-derived activated carbon with free binder electrode design for solid-state supercapacitor application

The aim of this research is to formulate activated carbon monolith from hazardous waste of cigarette filter butts (CFB) for electrode material monolith design in solid-state supercapacitor application. Potassium hydroxide (KOH) was selected for activation. The ratio of CFB to KOH varied in terms of weight between 1:2 and 1:4, thereby obtaining activated cigarette filter carbon (ACFC). The carbon that has been obtained is designed to be solidly in the form of an additive-free monolith. Monolith-activated carbon is physically characterized to examine thermal decomposition profiles (pre-carbonized), structure, composition, morphology, surface area adsorption, and electrochemical measurements. The optimum precursor was marked with high wettability with self-O-doped of 5.44%.in carbon content of 94.56%. Activated carbon electrodes prepared from ACFCs showed an optimum specific capacitance of ~87.17 F g-1, which is a more ecologically responsible method of producing supercapacitors.

Development of environmentally friendly catalyst Ag-ZnO@cellulose acetate derived from discarded cigarette butts for reduction of organic dyes and its antibacterial applications

The release of harmful organic dyes from different industries besides its degradation products is a major contributor to environmental contamination. The catalytic reduction of these organic pollutants using nanocomposites based on polymeric material presents potential advantages for the environment. In this study, novel nanocomposite based on cellulose acetate (CA)-derived from discharged cigarette butts and zinc oxide nanoparticles (ZnO NPs) was prepared utilizing a very simple and low-cost solution blending method and used as support for silver nanoparticles (Ag NPs). A simple reduction method was used to anchor different percentages of Ag NPs on the ZnO@CA nanocomposite surface via utilizing sodium borohydride as a reducing agent. The Ag-ZnO@CA nanocomposite was characterized using X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy. The TEM analysis showed spherical Ag NPs, with an average diameter of ∼17.6 nm, were uniformly anchored on the ZnO@CA nanocomposite surface. The prepared nanocomposites were evaluated as catalysts for the reduction of organic dyes in water. It was found that 10 % Ag-ZnO@CA nanocomposite showed a remarkable reduction of Rhodamine B (RhB), Rhodamine 6G (Rh6G), Methylene Blue (MB), and Sunset Yellow (SY) dyes in short time. In the presence of this nanocomposite, the rate constant, kapp values for RhB, Rh6G, MB, and SY were 0.3498 min−1, 1.51 min−1, 0.2292 min−1, and 0.733 min−1, respectively. This nanocomposite was recovered and reused in five successive cycles, with a negligible loss of its activity. Furthermore, the nanocomposites demonstrated moderate antibacterial activity toward Staphylococcus aureus and Escherichia coli. Thus, this study directed attention on recycling of waste material to a valuable nanocomposite and its applications in environmental protection.

Cigarette Butts as Water Emerging Contaminants: Possible Method for Their Remediation

Nano-sized particles derived from cigarette butts (CBs) are extremely small particles, typically less than 100 nanometers in size, generated by the degradation or breakdown of CB materials. The potential impact of nano-sized particles derived from CBs on irrigation water is a topic of concern. Despite the lack of research focusing specifically on these aspects, it is essential to consider the potential risks associated with these particles. The presence of toxic compounds in CBs, such as nicotine, heavy metals, and polycyclic aromatic hydrocarbons (PAHs), raises concerns about the potential health risks of consuming water contaminated with nano-sized particles from CBs and the potential for these particles to accumulate in the soil, affecting nutrient availability and overall crop growth. Nano-sized particles can travel through water systems and may reach irrigation channels and sources through various pathways, and if CB nano-litter is present in nearby surface water bodies or infiltrates into groundwater, it can introduce these particles and associated contaminants into water sources and the agricultural environment. To ensure the safety and limited entry into water sources used for irrigation it is crucial to implement effective water treatment processes capable of removing or reducing nano-sized particles, as well as the associated chemicals, from the water supply. To mitigate potential risks, various water purification methods can be considered, such as the use of magnetic biochar. Magnetic biochar is a type of biochar that is enriched with magnetic materials. It has been explored as a potential tool for wastewater treatment due to its ability to attract and adsorb contaminants. The hybridized properties of both organic and inorganic materials in magnetic biochar promote its adsorptive ability for a wide range of contaminants. Also, it has unique properties such as solar responsiveness, reusability, magnetic recovery, magnetic recovery, and surface functionalization which are desirable in the design of recyclable adsorbent for industrial wastewater treatment. Therefore, by incorporating magnetic biochar in water treatment systems, it may be possible to effectively remove nano-sized particles derived from CBs, along with other pollutants and contaminants, from water. For example, metal ions can be adsorbed via ligand exchange and complexation, while nicotine and PAHs are primarily via π-π interaction, hydrogen bonding, and electrostatic interactions. Therefore, the present study will assess the potential capacity of magnetic biochar to adsorb these particles, considering its impact on water remediation, soil health, and crop growth, and evaluate the overall cost-effectiveness and practicality of its implementation.

PERANCANGAN DAN IMPLEMENTASI SISTEM PENDETEKSI KEBAKARAN DENGAN MENGGUNAKAN REALTIME DATABASE

Fires can occur unexpectedly, even if you are careful when using equipment that produces fire. However, there are still several sources that cause fires, such as electrical short circuits, gas stoves, burning rubbish, cigarette butts and candles when the lights go out. The aim of this research is to create a tool that can detect fire and temperature in a room and can overcome (minimize) the threat of fire disasters based on a microcontroller and C language. This research uses a Fire Sensor to detect fire, a DHT 11 Sensor to detect room temperature, NODEMCU as microcontroller controlling input and output, Buzzer as a system monitoring tool. The system will be assigned to turn on the extinguishing system that uses a FAN if there is a significant increase in temperature or if the system detects a fire. The output from the Flame Sensor which detects fire will be processed into a microcontroller which has been programmed using C language so that it will produce two states, namely low, namely when no fire is detected, and high when fire is detected. Likewise for the output from DHT11. This tool will give a warning to the buzzer if it detects a fire, and also detects changes in temperature and gives orders to spray the fan if there is a significant change in temperature

Waterborne Toxicity to Neotropical Invertebrates and Hazard of Cigarette Butt Leachates in Marine Environments.

Cigarette butts (CBs) are the most common type of beach litter worldwide and contain a complex mixture of chemicals. Given the recent interest in this emerging problem, it is important to assess the toxicity of CB leachates to a range of species from different regions, sensitivities, and ecological traits. We evaluated the waterborne toxicity of smoked CB to tropical invertebrates. Leachates were prepared in the laboratory and characterized for trace elements (Mn, Fe, Co, Ni, Cu, Zn, As, Cd, and Pb), ammonia nitrogen, and polycyclic aromatic hydrocarbons. Then a set of toxicity tests with marine invertebrates was performed as follows: the brine shrimp Artemia sp. (nontoxic); the amphipod Tiburonella viscana (median lethal concentration [LC50] of 0.038 CB/L); the tanaid Monokalliapseudes schubarti (LC50 of 0.126 CB/L); the copepods Tisbe biminiensis (median effect concentration [EC50] of 0.038 CB/L) and Nitokra sp. (EC50 of 0.009 CB/L); pluteus stage larvae of the sea urchin Echinometra lucunter (EC50 of 0.152 CB/L); the sand dollar Mellita quinquiesperforata (EC50 of 0.054 CB/L); and D-stage larvae of the mussel Perna perna (EC50 of 0.005 CB/L). The predicted no-effect concentration was estimated using species sensitivity distribution, producing a 5th percentile hazard concentration of 0.015 CB/L. This preliminary threshold allowed us to estimate the potential impact of a single CB to 67 L of seawater via leaching, contributing to the advancement of knowledge regarding the contamination, toxicity, and ecological risks of cigarette waste.

Electrochemical-driven removal of organic dyes by using bimetallic MOFs /waste cellulose acetate derived carbon foam as a freestanding electrode material

Converting the solid waste into high-value products were significant to environmental protection and resources saving. Waste cigarette filters, were made of cellulose acetate, a common kind of solid waste in daily life. In this work, waste cigarette filters were used as cellulose precursors and decorated with bimetallic MOFs to fabricate a light-weight, monolithic and porous carbon foam. The specific surface area and pore size of as-prepared carbon foams can be regulated through changing the mass ratio of ZIF-8 to ZIF-67. Importantly, as-prepared samples exhibited good electrochemical performances when accessed a great balance between the surface area and conductivity. The sample of C/Zn/Co-0.5:0.5 exhibited an excellent electrosorption capacity for methylene blue, which was high up to 2847 mg g−1. Moreover, it had a superior stability, and the removal efficiency for methylene blue remained above 90 % after 5 cycles. Thus, this study successfully realized the conversion of waste cigarette filters into porous materials, which can be regarded as an effective and economic adsorbent used in wastewater treatment.

Review of the Policy, Social, Operational, and Technological Factors Affecting Cigarette Butt Recycling Potential in Extended Producer Responsibility Programs

Cigarette butts (CBs) are the most diffuse waste in the world, often abandoned into the environment without proper disposal. They are dangerous because of the numerous harmful chemicals potentially released by them into the environment. In the literature, there are several technological options for CB recycling, but some critical concerns could affect their effectiveness due to the quality and quantity of CB litter that is collected in the proper way. The extended producer responsibility scheme for CBs is proposed at the Europe level as an action to tackle CB litter and encourage sustainable product development. The present paper focuses on analyzing the existing literature to identify critical issues within the policy framework, social behavior, waste collection and transport, and technological processes. The collection and transport of CB waste is a major issue, being a key step for bringing CB to the recycling process. The main concern is the small quantity of CBs collected: 0.06% of the municipal waste and 0.18% of the unsorted waste in the case study’s administrative area of Perugia. Another crucial issue is the need for behavioral interventions to increase education and awareness of citizens that are smokers, addressing the discrepancy between smokers’ behaviors and beliefs. The main results, along with the critical issues related to the topics, are highlighted.

Cigarette filter fibres as a source and sink of trace metals in coastal waters

Cellulose acetate fibres from cigarette filters represent a form of microplastic that has received little attention in the environment. In this study, a ground composite of spent, smoked filter material (FM) has been used to investigate the role of cellulose acetate fibres as a source and a sink of trace metals (Cd, Co, Cu, Ni, Pb and Zn) in coastal waters. FM suspended in river water and seawater and mixtures thereof representative of an estuarine gradient resulted in the leaching of pre-existent metals derived from the combustion of tobacco, with mean percentages of release ranging from about 40 for Pb to nearly 90 for Cd, Co and Zn. Addition of 40 μg L−1 of each metal to FM suspensions incubated for 48 h yielded mean partition coefficients (KDs) ranging from <10 L kg−1 for Co to > 100 L kg−1 for Cu, Pb and Zn, with Cu and Ni displaying a net increase in KD with increasing salinity. Adsorption is interpreted in terms of hydrophobic interactions between metal-organic complexes and the cellulose acetate surface, and in support of this assertion KDs exhibited a significant, positive relationship with published metal-humic acid binding constants. The findings of this study improve our understanding of the role of cellulosic microfibres more generally in transporting trace metals in aquatic systems.

Role of Cigarette Butt in poor plant growth and nitrate levels

4.5 trillion cigarette butts are littered worldwide per year. Beyond the environmental damage that the cigarette butts&#x0D; themselves propagate through the ecosystem, the effects on plant reproduction and growth that cigarette butts pose is&#x0D; relatively unstudied. The hypothesis was that microplastics from cigarette butts will decrease the plant’s nutrition by&#x0D; decreasing nitrate levels in the soil and will also affect a plant&amp;#39;s growth based on the toxic materials in the cigarette&#x0D; butts. My procedure was that before I started the experiment, I would collect materials and make water solutions,&#x0D; and grow the microgreen seeds. From Day 1, I would transfer and label seed groups and experimental test groups&#x0D; with toothpick signs. Every day at 8 am, I would water each of the 15 seedlings with 1 mL of water or cigarette butt&#x0D; water. I would measure the height of each sample and take the average. I would send it to the lab for plant tissue&#x0D; testing. My final steps were to take the averages of height and mineral values for each experimental group, plot&#x0D; trends using the averages over the days, analyze data, and trace the individual trends of each seedling height and&#x0D; health for 11 or 16 days. Based on the given data of each graph of Brassica Oleracea over a 11-day period and&#x0D; Helianthus Annuus over a 16-day period and plant nutrient reports, I can safely conclude that cigarettes butts do&#x0D; affect plant growth and nitrate levels.
