<p>Procedure concerns recycling the waste produced during the use of 7 volt cells, Daniel cells and those of Calland-Cabert. It recycles the zinc sulphate produced by the Zn and sulphuric acid with the aid of carbon or refuse which contains paper or plastic. The waste from the three types of cells is recycled to produce cheap electricity without pollution and without conventional method of heating, using evaporators, turbines and cooling towers. Useful mainly in developing countries as the method calls for little capital but provides employment.</p> |
