Just now getting that adressed. the company I work for grew fast and has been playing catch up in the office end, I know when we send roll offs of wood to a local pallet recycler,weight is noted on the daily time sheet and seems like it would be easy to track at years end.no different than the scrap. Lots of organizing going on in the farm field based company I am employed with. (56 employees) We dontate usable building materials as well for the 501c3 tax credits, also wetake part in the Armstrong ceiling tile program for LEEDS.
