  • Cautions
    (Principle)
    • Observe the discharge rules (see "How to separate and dispose of laboratory waste").
    • Dispose of waste in such a way that it cannot easily leak outside.
    In addition to complying with the above principles, please pay attention to the following points.

    1. Number of plastic bags
    Since the following types of wastes pose a high risk of leakage, use at least two layers of plastic bags for storing experimental wastes.
    • Items containing a small amount of liquid (large amounts of liquid should be removed)
    • Items with a particle diameter of 1 cm or less (powdery items should be disposed of when collecting "unnecessary chemicals"
    • Sharp plastics, glass, etc. (especially tips used for pipettes, etc.)
    • Odoriferous materials (try to avoid odor)
    2. weight and size per unit
    To prevent tearing of plastic bags and damage to cardboard, and to ensure safety during collection and transportation operations, the weight and size should be as follows
    • Plastic bags used for storing experimental waste should have a capacity of 45 liters or less.
    • The weight of each piece of noncombustible cardboard should be less than 20 kg (approx.), and the maximum length should be about 50 cm.
    • Sharp plastics, glass, etc. should be less than 80% of the volume of a sealed plastic bag (as a rule of thumb). (Do not overfill.)
    3. Biological wastes
    Wastes associated with living organisms such as plants and fungi should be pretreated before discharge. However, infectious wastes (infectious materials, human organ blood, wastes related to animal experiments, etc.) are not included in experimental wastes.
    • Autoclave. (Remove as much liquid as possible.)
    • Items that require inactivation should be treated in an appropriate manner to ensure inactivation.
