The following conclusions can be drawn; 1. The drying technique is effective, but not yet optimised. 2. The separation of filler is close to expectations and it is reasonable to expect the proportion of fibrous contamination can be reduced from 30% currently to 25% and maybe lower. 3. It is proving that there are market applications for the separate products - applications that do not exist for wet sludge - and they are substantial enough to use any processed material that is made.
