>Dear Ms. Lisa
>How are you? I would like to introduce myself as Ashwin Arumugham 
>from the Industrial Assessment Center, University of Florida, 
>Gainesville. We are funded by the USDOE and are working under Rutgers 
>University, Piscataway. We perform energy audits for medium sized 
>manufacturing companies and come up with cost savings. We also look 
>in to productivity and waste.
>This is regarding a particular company that we had visited last week. 
>They manufacture utility poles and marine pilings. Basically it is a 
>lumber company. After drying the lumber, they treat it with a 
>chemical known as CCA ie Chromated  Copper Arsenate which is a 
>highly hazardeous chemical. After treating it, they cut it to the 
>required dimension and sometimes they are left off with 5 foot logs. 
>I would like to know as to what can done with these logs as far as 
>recycling it or selling it as scrap keeping in mind that the treated 
>wood has the hazardeous chemical in it. Sometimes even before 
>treating the wood, they have these 5 foot logs.
>Another point that we are considering to look into is the chemical 
>treatment cylinder. It is about 6-8 feet in diameter and about 40 
>feet long. It has a single door like the door for a bank vault. 
>It has about 130-135 bolts that have to be manually removed and put 
>on everytime they open it and close it. This is a time consuming 
>process and hence we would like to recommend them to have a better 
>door mechanism, so i would like to know what sort of a recommendation 
>can be given in this case.
>For quality control, they take a small sample from each and every log 
>and see if the chemical has penetrated to the required depth 
>(3 inches) and if the quantity of chemical is to the required level. 
>If they find out that it requires some more treatment, then it is put 
>back into the cylinder again. This rework takes a lot of time and 
>creates a bottleneck. Is there any way where the quantity of chemical 
>that penetrates the wood can be determined constantly without having 
>to remove the logs and take samples and check it out. If there was 
>any equipment or device that can do this, it will save a lot of 
>process time.
>I would like to know as to what sort of a recommendation can be 
>given and what necessary steps can be taken in this regard. I would
