<div>we feed green leaves directly into a biogas plant. About 10 kg green leaves per day yield daily about 1000 litres biogas. The veins and midribs of the leaves accumulate in the biogas plant as undigested debris. Our biogas plant is designed to enable the removal of the undigested debris from the digester, without stopping the methane production. This debris can very easily be briquetted in a briquette extruder provided with a 1 h.p., single phase, electric motor. I am quite sure that a hand operated briquetting machine would also work quite satisfactorily, but we Indians are too lazy to work with out hands.</div>
<div>Yours</div>
