In the implementation part of LEED reference guide it is writen that buying a toner from a cartridge remanufacturer or an equipment supplier that will take spent cartriges back is considered a sustainable choice.

So, can we include the toners/cartridges that are sent back to the manufacturer as satisfying the criterion for sustainable purchasing - ongoing consumables for this credit even if they don't satisfy the following EPP criteria:
1. containing at least 10% postconsumer and/or 20% postindustrial material;
2. containing at least 50% rapidly renewable material;
3. containing at least 50% materials harvested, extracted, and processed within 500 miles of the facility;
4. consisting of at least 50% Forest Stewardship Council certified paper products;
