        With adaptation of methanogenic granular sludge,
Koster & Lettinga (Biological Wastes, 1988, 25(1)51-60) were
able to obtain satisfatory methanogenic activity in potato
juice containing 9.1 g ammonia-N/litre.

        Says Ali Beba (India) that if you have a solar
heater, one of its best use is to produce hot water for
slurry mixing for biogas fermenters (Solar Energy, 1988. 40
(3), 281-287.

        Though frequently thought in Africa that dry dairy
manure gives better gas production than fresh manure, Chan
et al (Biological Wastes, 1988, 24 (4), 297-306) showed that
fresh manure gave a greater total volume of gas produced (
because of loss in organic materials in dried materials) but
methane yield based on m3CH4/kg volatile solids fed was the
same (0.05).

        Harvesting biogas from anaerobic lagoons was studied
by Safley and Westerman (Biological Wastes, 1988, 23(3),181-
193) and found that they produce between 0.02 and 0.05 m3/m2
/day (or 0.03 to 0.23 m3/m3/day based on lagoon volume).

        The potential for biogas production and anaerobic
treatment of of different wastes is amazing -
