One of the things that you should consider when putting battery storage on your home is whether or not the battery will be recyclable at the end of its life.
Recycling batteries at the end of their life has a number of benefits:
- It enables the recovery and reuse of materials including lead, iron, plastics, aluminium, copper, lithium, cobalt and electrolyte
- It diverts toxic and hazardous materials from landfill
- It ensures that batteries are managed safely
- There may be a financial return (depending on the battery type).
Often, one of the reasons that people put solar panels on their house and put in battery storage to collect the excess usage is to protect the environment and reduce the need for coal powered power stations. This can be counterproductive if you choose a battery that is made from toxic materials or has components that can’t be recycled at end of life of the battery.
When batteries go to landfill toxic substances can cause damage to the waste stream, waterways, humans and the general environment. This can be nickel, cadmium, lead or lithium ion.
