Investigation of the Use and Suitability of Plastic Waste for Molding Interlocking Stones in Port Harcourt

Port Harcourt is known in local parlance as the ‘Garden City’ of Rivers State. This so tagged because overwhelming presence trees (Green Life) and flowers Metropolis. But today, it different streets, gutters, rivers environs are littered with all types plastic waste (MSW). These municipal solid wastes (MSW), indiscriminately dumped at locations Garden City. Plastics constitute a major component these wastes; thus, this study was aimed Investigating Use Suitability for molding Interlocking stones Harcourt. In study, samples (bottles, cups, plates, spoons, cellophane bags), were collected randomly selected The area covered GRA Phase 1, 2, 3, Old GRA, Diobu axis, main town. (PET-Polyethylene Terephthalate) which after collection weighed mixed fine grains sand (4 kg). 5, 10 15 kg used to mix 4 kg. mixture heated under very high temperatures melted form homogeneous mixture. resultant then poured into molds same sizes (1.32 x10-3 M3). another reaction, grain cement respectively. mixtures strengths two interlocking (paver) measured compared confirm one them has better compressive strength 7, 14 & 28 days. A total fifty-four (54) twenty-seven made from other cement. Interlocks substances compared. result showed 14, days being comparable that t-test there no significant difference between mold by waste. implies Plastic Wastes can act suitable alternative material making excellent binding properties like recommends proper management disposal reduce environmental degradation.
