Abstract

In this paper attempts have been made to find a suitable means of containing and collecting this hazardous waste leachate. The proposed method of recycling with microwave using stabilization/solidification technique incorporates the use of cement and waste paints as the materials for the curing. The study shows the effect of the compressive strength of the waste paint in cement and the leakage level subjected to microwave heating. The experimentation conducted in this work involves microwave curing of cement and waste paints applying microwave power of 800W at 30%, 50%, 80% and 100% heating rate. In this work the cement mixed with different volumes of water was subjected to microwave curing for a specific timing using a 115 mm X 115 mm and 58 mm container. Waste paints and domestic pesticides containing toxic chemicals are cured with microwaves at different holding locations in the solidified cement to get the optimum compressive strength. From the present study it was realised that microwave cured specimen having better compressive strength than conventionally cured specimen and also having improved curing efficiency by reducing the curing time. The leakage test results also indicated that no leakage was observed after the specimens contained used paints submerged for a definite period of time.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
