DISPOSAL
Disposal Procedures for Li/MnO2 Batteries
The disposal of waste products in the United States is regulated
by the U.S. Environmental Protection Agency. The EPA Regulations
are listed in the "Code of Federal Regulations," CFR40, entitled
"Protection of Environment." Individual states and local communities
also may establish regulations covering the disposal of waste
products. These may be more stringent than the federal regulations
and may cover the disposal of household waste, which is not included
in the federal regulation. Thus, state and local agencies should
be contacted for their disposal guidelines.
The EPA has provided no regulations
or specific guidelines with respect to the disposal of Lithium
Manganese Dioxide cells and batteries. Until such time that
regulations or specified guidelines are issued, the following
is recommended for the disposal of DURACELL Li/MnO2
cells and batteries.
- Batteries in Household Use
Individual cells and batteries can be disposed of with other
household waste, but in compliance with local regulations.
- Commercial and Industrial
- The preferred procedure is for the cells and/or batteries
to be in a discharged condition for disposal.
- Li/MnO2 cells can be considered to be
"discharged" if the cell voltage, under a C/100 current
load (where C is the rated capacity in ampere-hours),
is below 2 volts.
- If not discharged, the cells or batteries should
be discharged at a current less than C/S amperes until
the voltage of each cell is below 2 volts as measured
per (1a) above. The recommended procedure is to discharge
the cell or battery through an appropriate resistive
load until the cell voltage is below 2 volts.
- "Discharged" batteries should be shipped, as hazardous
waste to a hazardous waste, facility for final disposal.
Disposal of these discharged batteries in a hazardous
waste landfill is permissible.
- If the condition (state-of-charge) of the cells or batteries
cannot be identified or if the disposer does not wish
to discharge or determine the state-of-charge of the batteries,
or if cells or batteries are leaking, cracked, opened,
vented, etc., or are otherwise no longer physically sound,
they must be shipped as a hazardous waste to a qualified
waste facility. At this facility they can be treated to
assure that they do not exhibit the characteristics of
a hazardous material and then disposed of appropriately.
- Collection and Handling
Commercial or bulk quantities of spent Li/MnO2
cells and batteries should be collected and transported
in a manner to prevent short circuit, compacting or mutilation,
or any other abusive physical or electrical handling that
would destroy their physical integrity. CFR40 provides
details and regulations for collection of hazardous waste
products.
- Shipment
DOT and EPA regulations cover the shipment of these cells
and batteries to a disposal site within the United States
(reference CFR49, paragraph 173.185(j) and CFR40). Individual
states may establish additional regulations. Your state
regulatory agency should be contacted for additional transportation
guidelines.
- Incineration
Li/MnO2 cells and batteries should not be incinerated,
unless suitable procedures are followed and appropriate
precautions have been taken by qualified handlers. Exposure
of these cells to high temperatures or fire can cause
the cells to vent and/or rupture.
Note: Guidelines for the disposal
of lithium batteries are continually under review. Duracell
can be contacted if additional guidance is required for the
disposal of Li/MnO2 batteries. Waste management
companies can provide assistance in the disposal of these
batteries.
