“…Yuan et al [51] produced unglazed fired ceramic tiles, incorporating shredded CBs at a rate of 1.5% by dry weight, and studied characteristics such as density, shrinkage, water absorption, and modulus of rupture. The increase in the percentage of CBs caused an increase in shrinkage and water absorption, whereas the density and modulus of rupture decreased.…”

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.

“…The examination of the results of permeability, viscosity, and softening point tests on samples containing 0.3% cellulose acetate bers, as well as 0.2%, 0.3%, 0.4%, and 0.5% bers from cigarette butts, indicates a signi cant improvement in the physical and rheological properties of modi ed bitumen with bers. In a study conducted in 2021, Yuan et al added recycled cigarette butts in weight ratios of 0.5, 1.0, and 1.5 percent to unfritted ceramics, comparing the results with ceramics without cigarette butts (Yuan et al 2021). This investigation focused on the chemical and mineralogical characteristics, density, shrinkage, water absorption, fracture resistance, and exural modulus of the ceramic tiles.…”

Today, the accumulation of discarded cigarette butts in the environment, particularly along coasts and near seas, not only poses environmental challenges but also threatens the ecological balance of rivers and aquatic life. Exploring the feasibility of using cellulose acetate fibers from cigarette butts as reinforcements in the production of silica fume concrete has resolved this environmental issue. The inclusion of these hazardous materials has simultaneously improved the mechanical properties of the concrete. In this study, cellulose acetate fibers obtained from cigarette butt filters were added to silica fume concrete in 10 different volume ratios. The compressive strength, Brazilian tensile strength, and flexural tensile strength of these concretes were investigated in 10 mixing designs. The findings indicate that adding 0.2% by volume of fibers to silica fume concrete yields the highest compressive and tensile strengths among the designs. This results in a significant increase of 16% and 34% in the concrete's compressive strength and a 70% and 38% increase in Brazilian tensile strength at 7 and 28 days, respectively, compared to the state without cellulose acetate fibers. The addition of these fiber ratios also increases the flexural tensile stress capacity by 56%. Furthermore, the beam specimens subjected to testing exhibit a 287% higher vertical deformation tolerance compared to the state without fibers. Additionally, the energy absorption capacity of the concrete beam increases considerably.
