Potential of low-value plastic waste (LVPW) in concrete through latrine ring manufacturing

Abstract

In this research, Low-value plastic waste (LVPW) is used in concrete as a potential solution for sustainable waste management in the construction industry. In concrete, LVPW is utilized to produce Eco-Ring (Eco-conscious Latrine Ring). The use of a mix ratio of 1:2:3 and 1:2:4 in concrete mixes is studied. The impact of the percentage of recycled plastic on the mechanical properties of the final product is analyzed. The results show that the use of LVPW reduces both strength and unit weight but ensures its solidification. Sufficient strength for latrine rings is maintained, ensuring a balance between structural integrity and waste reduction. LVPW incorporation offers cost savings, with reductions of aggregate use up to 10%–15% in the present analysis. Justified consideration of the impact on mechanical properties, along with potential adjustments to optimize the compatibility and address workability/aesthetics, can help maximize the benefits of this technology.
