Of course this all depends on costs, as if there is a huge<br />difference in waste amounts you will need a very big digester.<br /><br />All the best,<br />HOOROO<br /><br />Mr. Paul Harris, Room 202 Charles Hawker Building, Faculty of Sciences, The <br />University of Adelaide, <br />Waite Campus, PMB 1, Glen Osmond SA 5064 Ph : +61 8 8303 7880 Fax :<br />+61 8 8303 4386<br />Roseworthy Campus, Ph : +61 8 8303 7929<br />mailto:paul.harris@adelaide.edu.au <br /><a href="http://www.adelaide.edu.au/directory/paul.harris" target="new">http://www.adelaide.edu.au/directory/paul.harris</a><br /><br />CRICOS Provider Number 00123M<br />This email message is intended only for the addressee(s) and contains<br />information that may be confidential and/or copyright.

The only viable<br />solution is to add some material like green waste or straw and keep it<br />mixed. Given that your waste material is probably 95% water, I am not sure<br />it is viable financially.<br /><br />Randy<br /><br /><br />Randy M. Mott<br />President<br />CEERES Sp. z o.o.<br />Ul.
