2. Categories of Wastes
Wastes discharged from laboratories fall into two main groups, "Wastes to Be Recycled" and "Wastes to Be Disposed of". The concepts used in the past, "wastes discharged from experiments" and "the other general wastes" are no longer applicable..
(2-1) Wastes to Be Recycled
2-1-1) Papers:
Most paper waste is recycled. Paper materials that cannot be
recycled are limited, as follows: paper food wrapping (as well
as raw garbage), papers soiled during cleaning, cotton waste,
paper cups, paper plates, paper milk cartons, carbon paper, heat
sensitive paper, and paper with vinyl-coating.
Divide other paper waste into the following categories:
"Newspapers",
"Regular Paper", and
"Magazines and Other Paper",
and put them into the correct recycling boxes. Please refer to
the poster if unclear about the three categories (please note
a correction: Advertisements folded into newspapers are to be
placed into "Magazines and Other Papers" box). There
is no need to remove staples, but remove any metal fittings larger
than staples.
Place cardboard boxes next to the recycling boxes. Do not place
them next to the carts at the cart station. If any styrene foam
(Styrofoam) materials are glued on to the cardboard box, remove
them (place the styrene foam materials into Cart 7). The contractor
comes to collect the waste once a week. Bring large cardboard
boxes to the paper waste recovery area located at the side of
the former incinerator.
If you have any confidential documents, paper shredding may
be ordered through the office.
2-1-2) Beverage Cans:
The cost necessary for collecting cans is included in the price of the beverage. If the beverage was purchased from the Co-op's vending machine, put the empty can into the can collecting box installed next to the bending machine. As for beverages purchased within the Co-op's shops, the empty cans may be put into the can collecting box installed within the Co-op's cafeteria.
As mentioned above, it is preferable if the beverage cans
are brought back to the place of purchase, but if this is inconvenient,
rinse the can with water, and put them into Cart 1. Both aluminum
and steel cans may be deposited.
2-1-3) Beer Bottles; 1.8L-Bottles for Sake:
As these bottles are returnable, ask liquor shops to come and collect them.
2-1-4) Chemical Bottles, Beverage Bottles (bottles that are not returnable):
Chemical bottles (brown or clear bottles containing reagents commercially available), and beverage bottles (excluding beer bottles and 1.8L-bottles for Sake) made of soft glass are to be put into Cart 2 after rinsing. There is no need to remove the caps and labels. The liquid used for rinsing chemical bottles will also be collected as waste fluid.
2- 1-5) Plastic Bottles (PET Bottles):
Remove the cap, and if possible, remove the label also. Rinse with water, put into Cart 3 (put the removed plastic label into Cart 4, and the cap into either Cart 4 or 6 depending on its material).
2-1-6) Styrene foam (Styrofoam) Materials Used for Packing:
Clean styrene foam packing vessels and fillers are to be put into Cart 7. Bulky ones may be put into the cart as it is, but small pieces of fillers must be put into clear polyethylene bags before putting into the cart. It may be difficult to be distinguished, but polyethylene foams and polyurethane foams are categorized as "Plastics", and should be put into Cart 4. Do not put any styrene foam used as food containers into Cart 7. Put them into Cart 4 as plastics, or bring them for recycle by the counter circulation system as written below.
2-1-7) Co-op's Lunch Boxes:
The body of Co-op's disposable lunch boxes (the styrene foam boxes with a mark 6 written inside an impressed triangle) are to be returned to the Co-op's collecting box. Other plastic food containers are put into Cart 4 after rinse (below).
