I'm modeling production of wood furniture. There are offcuts and sawdust from the production process as outputs; however, these will be re-used (by someone else) for heating (incineration) or for manufacturing (medium density fiberboard, for example). I want to credit my system with the environmental "savings" from these waste products being used instead of new trees being cut down for heat/manufacturing. So now I have these outputs: wood waste; wood, sawdust; and Add Cut Timber Scrap 100% PCR - AU (from Evah's Oz database).
1) Do I just mark those outputs as avoided products?
2) What if I'm going to be re-using those waste products myself? How does your answer to #1 change?
3) Per the answer to https://ask.openlca.org/596/when-should-i-check-this-option-avoided-product,
why do I need to create a process for that avoided flow when I'm not the one (re-)using the materials?
