Background: Plastic bottles of the PET type are still one of the most common pollutants found in Cameroon's cities, particularly in its two major metropolises. They are most often found in periods of flooding irrigated by rivers and agglomerated in catchment areas and in discharge works. Government policies to collect them are weak and do not mainly promote their reuse in view of current research. Objective: The aim of this study is to valorise the use of Polyethylene Terephthalate (PET) plastic waste as a binder in the production of roof tiles. Methods: To this end, the melted plastic waste was mixed at different ratios with a 2 mm sieve fraction of Sanaga alluvial sand. The said sand was initially tested and found to be a clean sand, 88.60% sand equivalent, fine grained with a good gradation within the range recommended by NPF18-560. The plastic/sand ratios formulated were: 90/10, 80/20, 30/70, 40/60, 50/50, 60/40, 70/30, 80/20 and 90/10. Results: These samples were subjected to some analysis and it was found that: all the formulations with more than 20% of plastics have a water absorption rate lower than 2.25%, which is in line with the ISO 62: 2008 standard which defines a limit rate of 6% for roof tiles. Furthermore, the porosity test, for the same formulations, shows a rate lower than 4.37%. As for the mechanical characteristics, a high flexural strength ranging from 2.66 to 5.31 MPa was found for formulations ranging from 10 to 50% plastic. Beyond these formulations, the strengths fall continuously for values below 1 MPa. For compressive strength, the following three ratios show better characteristics: 30/70, 20/80 and 90/10 with values of 7.31 MPa, 7.08 MPa and 6.88 MPa respectively. Conclusion: In the end, the ratio with the best characteristics (30/70) made it possible to formulate a Romaine II type tile with optimal impact resistance and waterproofing valued at 540 FCFA per unit.
