<div>Dear Paul,</div>
<div>the European countries and also the USA have rather strict rules, specifying what a biogas plant should do and how it should be made. In India, the biogas plants are constructed by village artisans, using locally available material. There do not exist any specifications regarding the material to be used. The Governments in the West do not realise that biogas is a very safe technology. I have not heard of a single accidental explosion or of a fire arising from a biogas plant, but one reads almost daily about explosions and fires from LPG. There were even reports from South America of a sausagelike biogas plant made out of relatively thin plastic film. I don't think there has been an accident with any of those, but something like that would never be allowed in Europe or USA. There also appear to be rules about effluents from a biogas plant. Antibiotics were mentioned in one of the previous postings. Do they really persist in the effluent? </div>
<div>Yours</div>

<p class="MsoNormal"><span style="COLOR: #1f497d; FONT-SIZE: 11pt">In my opinion anaerobic digesters are just part of a waste treatment system that may also generate energy and organic fertiliser. The type of digester needs to be selected keeping in mind the expertise and situation/climate in which the digester will operate. With this in mind the digesters suitable for Europe (and North America?) will probably not be suitable for most situations in Australia (where we have LOTS of space and technical support may be a long distance away) and definitely not for some of the less developed tropical countries. That said why should the less developed countries (who need, not want, energy more than Europe and USA) be deprived of the benefits of AD, where some treatment is better than none, because they don’t meet “our” standards?</span></p>

<p class="MsoNormal"><span style="COLOR: #1f497d; FONT-SIZE: 11pt">We are all trying to learn, but I think one of the reasons AD is not greatly accepted/adopted in Australia is the perceived complexity/cost.</span></p>
