The study aimed to assess the implications of burning tyres for cattle skin processing in slaughterhouses, focusing on challenges and solutions. Methodologically, a comprehensive investigation was conducted in five slaughterhouse locations in Port Harcourt, Nigeria, utilizing a completely randomized block design for data collection. Air quality tests were performed to measure concentrations of various pollutants, including sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), volatile organic compounds (VOCs), methane (CH4), hydrogen sulfide (H2S), ammonia (NH3), and suspended particulate matters (SPM2.5 and SPM10). The mean concentrations of these pollutants were analyzed using ANOVA and Duncan Multiple Range Test. Results indicated significant variations in pollutant concentrations across slaughterhouse locations and periods. For instance, Rumuokoro consistently exhibited higher levels of pollutants compared to other locations. Major findings included mean morning concentrations of SO2 (0.471 μg/m3), NO2 (0.987 μg/m3), CO (0.789 μg/m3), VOCs (625.867 μg/m3), CH4 (0.412 μg/m3), H2S (0.726 μg/m3), NH3 (0.889 μg/m3), SPM2.5 (64.714 μg/m3), and SPM10 (62.367 μg/m3) at Rumuokoro. In conclusion, exposure to emissions from burning tyres poses significant risks to public health and the environment, particularly in urban areas. However, solutions are available to mitigate these challenges. Proposed solutions include implementing alternative waste disposal methods, strengthening regulatory enforcement, launching public awareness campaigns, investing in technology for waste management, fostering collaboration and partnerships, providing training and capacity building, and supporting research and innovation initiatives.
