LCA

Epishine_img_solarCell_02

Electronic Shelf Labels
Light powered carbon footprint up to 85% lower than battery powered
- Powered by four CR2450 batteries with one battery change
- Total eight batteries
- Estimate of CO2 footprint for LiMnO2 batteries: 400g CO2eq per 49g LiMnO2 battery². Rescaled carbon footprint to CR2450 (6.2g / battery): 50.6g CO2eq
- Carbon footprint of 4 CR2450 alkaline batteries: 202g CO2eq
- LEH Active area: 7.7cm2
Remotes
Light powered carbon footprint up to 80% lower than battery powered
- Powered by two AAA batteries with one battery change
- Total 4 AAA batteries
- CO2 footprint for alkaline batteries: 107g¹ for one alkaline AA battery with average weight of 23 g. AAA average weight is 12g => 55.8g CO2eq estimated per AAA alkaline battery
- Carbon footprint of 4 AAA alkaline batteries: 223g CO2eq
- LEH Active area: 13.2cm2
