A common problem associated with manhole covers is the theft of the cover made out of cast iron and then selling it on the black market leaving a large empty hole in the road causing many potential safety and health hazards. This paper investigates the reinforcement of unrecyclable thermoplastic rejects to be used in the application of a manhole cover. Foundry sand and steel were used with the thermoplastic rejects as reinforcement of the material. Foundry sand is a hazardous waste that may cause many potential health hazards. It was shown that with 10% foundry sand, 90% thermoplastic rejects, and a steel mesh of diameter size 12 mm reinforcement, the manhole cover could withstand an average load of 112 kN. This value exceeds Grades A, AA, AAA, and B of acclaimed standards BS EN 124 for manhole covers, which ultimately indicates that the manhole cover may be used in pedestrian precincts and areas with occasional vehicular access. This composite material is produced out of waste materials (foundry sand and un-recyclable thermoplastic rejects) thus not utilizing or depleting the earth's natural resources, and eliminating the safety hazards, health hazards, and pollution associated with these waste materials. Not only is this product a benefit to the environment, but also inexpensive due to the fact that the materials are un-recyclable waste materials, and thus do not attain any value or cost.
