Prévalence et catégorisation des plastiques rencontrés dans les décharges au Tchad: Une étude de cas

Description

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.
