The FAO Code of Conduct about pesticide "disposal"
5.2
Even where a control scheme is in operation, pesticide industry should:
5.2.3
make every reasonable effort to reduce risks posed by pesticides by:
5.2.3.4
using returnable and refillable containers where effective container collection systems are in place;
5.2.3.5
using containers that are not attractive for subsequent reuse and promoting programmes to discourage their reuse, where effective container collection systems are not in place;
5.3
Government and industry should cooperate in further reducing risks by:
5.3.3
establishing services to collect and safely dispose of used containers and small quantities of left-over pesticides;
10.3
Pesticide industry, in cooperation with government, should ensure that:
10.3.1
packaging, storage and disposal of pesticides conform in principle to the relevant FAO, UNEP, WHO guidelines or regulations or to other international guidelines, where applicable;
10.5
Governments, with the help of pesticide industry and with multilateral cooperation, should inventory obsolete or unusable stocks of pesticides and used containers, establish and implement an action plan for their disposal, or remediation in the case of contaminated sites, and record these activities.
10.6
Pesticide industry should be encouraged, with multilateral cooperation, to assist in disposing of any banned or obsolete pesticides and of used containers, in an environmentally sound manner, including reuse with minimal risk where approved and appropriate.
10.7
Governments, pesticide industry, international organizations and the agricultural community should implement policies and practices to prevent the accumulation of obsolete pesticides and used containers.
