No, that's not hugely efficient, but it could add up. Energizer believes that EcoAdvanced should reduce the amount of mining it needs, and the move might give you a stronger incentive to recycle batteries that you'd otherwise be tempted to throw away. More importantly, the process should become much more efficient in the next decade. Energizer hopes that its batteries will use 40 percent recycled material by 2025, which could go a long way toward reducing your environmental impact in those situations where rechargeable batteries just aren't an option.
