Dear friends,<br>
<br>
<br>
Well... That was quite a flurry of messages, no?<br>
<br>
Many of you are familiar with the work of T.R. Preston, who for many
years worked on plastic digesters. For example, he was one of the
authors of a classic in the literature regarding the use of what was
then called "Red Mud PVC" plastic to create a 15 cu m digester. (The
list discussed his work briefly in January of this year. Will the
old archives be ported to the new server?)<br>
<br>
In any case, I would very much appreciate-- if anyone on the list
knows-- having a current email address for him, as I have some
questions I would like to ask. If you have his address, please write
to me off-list.<br>
<br>
