A Survey on Design of Pavement Blocks Made from Waste of Plastic, Glass & Aluminum Foil

Abstract

Abstract: The aim of the project is to recycle the plastic waste into a paver block and to reduce the cost of the paver block when compared to that of a convention concrete paver block. Plastic waste has become a major problem these days. As plastic is non bio degradable material it blocks drains, pollutes rivers and wreaks havoc on the environment. At present nearly 56lakhs tones of plastic waste is produced in India per year. As the degradation of the plastic waste is a very slow process so here is an idea of mixing sand into melted salvaged plastic to make a solid, durable material as a paving slab. Hence, we have a “eco-friendly” paving block. Unlike other processes of making porous blocks, which usually involve incineration to burn combustible materials in order to form pores with implication of high carbon emission, the proposed process is non-destructive in that the blocks are merely baked at low temperature, sufficient to melt the waste plastic that gets diffused within the body of the blocks. The compressive strengths after addition of waste plastic are same as normal block strength. And also reduce the water absorption capacity of block is reduced compare with nominal block. Efflorescence values were low than the normal block. The blocks are likely to add energy efficiency in buildings and help create economic value to manufacturers, thereby, encouraging the ecosystem of plastic waste management involving all actors in the value chain. A mathematical model is developed to predict compressive strength of blocks at varying plastic contents. The study introduces a new strand of research on sustainable thermoplastic waste management.
