Preparation of Wastes
The paper waste (PW) was soaked in a plastic water bath overnight to allow for partial decomposition by aerobic microbes [19], and the pH was noted. For the PW-A, 8kg of the paper waste was mixed with 27kg of water, while for the PW: CD, 4kg each of paper waste and cow dung were blended and mixed with 27kg of water, bringing all of them to water to waste ratio of approx. 3:1. The moisture content of the wastes determined the water to waste ratio.
