<br>Dear Randy,<br>I give below information about a small biogas plant developed by us. You can<br>contact me personally if you want commercial information.<br>Yours<br>A.D.Karve<br><br><br>*ARTI biogas technology*<br><br>
<br><br>*Background*<br><br>? The organisms that produce biogas reside in the intestines of<br>animals. They exit from the animal body along with dung.<br><br>? The traditional biogas plants use dung as feedstock. 1 kg dung<br>
produces about 20 to 30 litres biogas after a fermentation period of about a<br>month.<br><br>? ARTI scientists argued that since these organisms lived in the<br>intestines, they ate what the animals ate.<br><br>? Experiments with human food showed that 1 kg (dry weight) of human<br>
food yielded 600 to 800 litres biogas within a fermentation period of just<br>24 hours.<br><br>? ARTI biogas system, based on human food waste, is about 600 to 800<br>times as efficient as the dung based biogas plant.<br>
<br><br><br>*Compact biogas plant by ARTI*<br><br>? Because of lower feedstock requirement, and because it is consumed<br>rapidly, ARTI biogas plant is small. A 1000 litre digester is sufficient<br>for a family.<br>
<br>? Small size of the plant allows it to be accommodated in any<br>available space, even on the terrace of a house.<br><br>? Fabricated from locally available plastic water tanks, it is<br>installed in just a couple of hours. It can even be moved around.<br>
<br>? Food waste is plentifully available in urban areas from<br>restaurants, canteens, vegetable markets, fruit juice vendors, flour mills,<br>oil mills, etc.<br><br>? Therefore, technology is suitable for urban areas. Almost 5000<br>
plants of this type have so far been installed in India and abroad.<br><br><br><br>*Special features of ARTI biogas plant*<br><br>? Ideal technology for disposal of wet garbage. A 1000 litre plant<br>accepts daily about 2 kg wet garbage.**<br>
<br>? In nature, the methanogens get their food masticated by animals.<br>Therefore, food waste must be pulped before introducing it into the biogas<br>plant. **<br><br>? About 10 litres water is needed daily as a carrier of the<br>
feedstock. It generates daily 10 litres effluent. **<br><br>? Because food waste gets completely converted into biogas, the<br>effluent is watery. It can be recycled or used for watering plants.**<br><br>? In the case of industrial canteens, hostels, resorts and housing<br>
colonies, the design and size of biogas plants depend on the amount and type<br>of waste and the available space.**<br><br>* *<br><br>*A rural biogas plant using green leaves as feedstock*<br><br>? Experiments with green leaves showed that 10 kg pulped green<br>
leaves produced 800 to 1000 litres biogas. **<br><br>? However, midribs, veins and petioles accumulate as undigested<br>debris inside the digester and ultimately choke the system.**<br><br>? A prototype has been developed from which the accumulated debris<br>
can easily be removed without stopping biogas production. **<br><br>? Such a plant can be introduced into rural areas, as growing a<br>leafy crop or plucking leaves from existing vegetation is possible. **<br><br>
* *<br><br>*A method for green leaf production*<br><br>? 50 to 100 sq.m.plot surounded by a skirting of transparent plastic<br>film is planted with a high yielding multicut fodder species. **<br><br>? Effluent and leaf debris from the biogas plant provide nutrients<br>
to this plot. Daily water requirement is between 5 to 8 litres per sq.m. **<br><br>? 1 or 2 sq.m.area is harvested daily. Leafy waste from crops like<br>cabbage, carrot, radish, and weeds from the field are also acceptable.**<br>
<br><br><br>*Purification of biogas*<br><br>? Biogas contains volumetrically about 40% carbon dioxide and 60%<br>methane.<br><br>? Therefore biogas has a calorific value of only about 4000 kcal/kg<br>as against about 11000 kcal/kg of pure methane.<br>
<br>? Storing biogas in a moving drum floating over water removes carbon<br>dioxide from biogas.<br><br>? 95% pure methane is obtained after 3 days.<br><br><br><br>*Biogas as fuel in internal combustion engine*<br>
<br>? Biogas can replace 100% petrol or kerosene and 80% of diesel.<br><br>? It is quite possible to use biogas in unpurified state in internal<br>combustion engines.<br><br>? Using it in stationary engines for pumping water or for generating<br>
electricity causes no problems.<br><br>? Using it as vehicular fuel is difficult, because it involves<br>compression of biogas and filling it into cylinders.<br><br><br>On Wed, Jan 5, 2011 at 3:48 PM, Randy Mott <<a href="mailto:randymott@ceeres.eu" target="_blank">randymott@ceeres.eu</a>> wrote:<br>
