Special / Problem Waste
Problem waste is discarded in the plastic yellow boxes found in each lab. When filled (do not overfill), the box is closed with a self-sealing lid and labelled using the orange “FORBRENNING” labels. Check mark the relevant type of waste, and fill in the date, department, lab telephone number, and name (see label below). The sealed labelled box is then placed in the waste room on the HIB 1st floor (see the admin front desk for access key). Empty yellow boxes, lids, and labels are picked up from the same room. Boxes and their content will be destroyed by incineration by BIR at Rådalen.
Note: Put only one category of waste in each yellow box, the exception being Ethidium Bromide waste (see last category)
- Sharp waste ("stikkende/skjærende"): sharp objects such as scalpel blades, needles, broken glass, cover slips etc. should be collected in suitable small plastic containers in the lab. When full, labs are responsible for placing these into a yellow box. The boxmust be marked with the orange tag labelled "FORBRENNING", and indicated for "stikkende/skjærende". The sealed labelled box is then placed in the waste room on the HIB 1st floor (see the admin front desk for access key).
- Gels ("Geler"): agarose gels containing EtBr and SDS gels containing polyacrylamide.
- GMO: genetecally modified animal waste
- Chemically contaminated plastics (tick off the empty box): disposable plastics (paper and gloves) that have been in contact with chemicals. Mark the empty box and fill in the label accordingly.
- "Cytostatika":Chemical compounds which have the ability to prevent the growth and proliferation of cells – e.g. mitotic cycle inhibitors such as Cytochalasin B, colchicine or Nocodazole. All lab waste generated in connection with the use of cytostatica is problem waste (e.g. tips, tubes, gloves, plastic disposables), and can be disposed of in the yellow boxes. However the actual cytostatic compounds are hazardous waste and must be handled accordingly (see section on hazardous waste disposal below).
- Ethidium Bromide contaminated waste: all gels, solid decontamination materials, gloves, paper, and plastics can be placed together into one yellow box. Mark the label as Geler and fill in the empty category as EtBr contaminated paper /plastics.
