The effect of co-pyrolysis of coconut husk and sewage sludge on the bioavailability and environmental risk of Pb and Cd

Abstract

There are a lot of the research about the sewage sludge with the pyrolysis and also the HTC. However, a recent study show only use the method with only the sewage sludge with not give the best result for the char because of the high ash content. .So the sewage sludge must be pair with the coconut husk which is according to study has low ash content. This study the co HTC between the biomass and the sewage sludge to give the best result to find the bioavailability. The purpose of this study is to investigate the present of the Cd and Pb in the hydrochar.
