Prevention of Toxic Seepage from Landfill to Groundwater Using Natural Latex

Abstract

This research aims to study the development of compacted clay liner of landfill using natural latex. High plasticity inorganic clay is mixed with natural latex in 5 different ratios including 0, 2.5, 5, 7.5 , and 10% by weight of clay. From physical, mechanical, and cracking tests, it was found that the natural latex could improve the properties of compacted clay liner like higher unconfined compression, lower water permeability, higher dry and wet density, and lower cracking. The appropriate amount of natural latex by weight of clay that could improve the satisfied properties and cost of compacted clay liner is 5%. Moreover, the natural latex could reduce the leachate from compacted clay liner of landfill to environment.
