There are no laws in Australia regarding hearing aid disposal. Up to 97% of hearing aid button cell batteries end up in household waste potentially causing damage to our health and the environment. Adding to this, the processes used to create and distribute batteries are not eco-friendly. Hearing aid batteries are typically made of zinc, mercury and steel and are called zinc air batteries. A typical hearing aid battery lasts a week. So if you are wearing two hearing aids, you will be using around 104 disposable hearing aid batteries a year.If you are using disposable batteries with your cochlear implant processor, which has greater power requirements, you would be using around 312 batteries for each processor. Many audiology clinics collect used batteries and forward them to the council for recycling. Unfortunately, Australia can only recycle car (lead-acid) batteries and all other types including hearing aid batteries are sent overseas for recycling.Some battery companies such as Hearing Aid Batteries Express have invested in a recycling bin from French utility company Suez Environnement. Used batteries can be forwarded to Habex (preferably by road mail) and they fund shipping to Suez Environnement for recycling. Adding to these sustainable projects, a European Union ban on mercury as a stabilizer in button cell batteries became effective from October 2015. Following the same ban in many US states, the EU ruling sends out a clear international message that mercury-containing batteries should not be manufactured or offered for sale. Where possible, look at rechargeable battery options. Not only are they cheaper for you, they are substantially less harmful for the environment.
