5.4. Disposing of Drying Agents
Please note that drying cells are replaced or refilled by Sterling only if they are empty.
When disposing of drying agents, observe all official rules.
Since used drying agents may contain impurities from the dried
materials, treat them as special waste.
It is not possible for Sterling to take back the used drying agent
or drying cells with used drying agents.
