Background: The management of plastic waste is a major challenge in Chad. Plastics are ubiquitous in landfills due to their widespread use in various sectors. This study aims to assess the prevalence and categorize the plastics found in landfills in Chad. Methods: A quantitative and qualitative analysis of plastic waste was conducted in several urban and rural landfills in Chad. Data were collected over a six-month period using waste sorting and weighing methods. The selected landfills include those in N'Djamena, Moundou, and Sarh. Results:Plastics account for approximately 20-30% of urban solid waste in Chad. The main sources of plastic waste include food packaging, plastic bottles, and plastic bags. The most common types of plastics are polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), and polystyrene (PS). Conclusion: The management of plastic waste in Chad requires urgent interventions to reduce its environmental impact. Policies for the reduction, reuse, and recycling of plastics must be implemented to mitigate this growing problem.
