Home soda dispensers have become increasingly popular as more households seek to reduce their use of plastic bottles. According to Consumer Reports, these machines can pay for themselves in savings after about two years. However, it’s important to consider the sustainability of the CO2 gas and canisters they use.
CO2 is a greenhouse gas that contributes to global warming. While the CO2 used in soda machines comes from industrial sources like ammonia or natural gas production, it is not a direct source of atmospheric CO2 emissions. Companies like SodaStream may not disclose the carbon footprint of their CO2, but it’s clear that the gas is sourced from industrial processes.
Recycling CO2 Canisters
Most CO2 canisters used in home soda machines are made from recyclable aluminum. However, recycling these canisters can be challenging due to safety risks. Pressurized canisters can pose hazards in recycling facilities and are not accepted in curbside recycling programs. It’s important to find a local drop-off option that can handle pressurized items safely.
Manufacturer Exchange Programs
To address the challenges of recycling CO2 canisters, many manufacturers offer exchange programs. These programs promote reusing canisters, which is a more sustainable option than producing new ones. Some retail outlets also offer exchange services, but it’s advisable to check with the store beforehand.
While naturally sourced CO2 may not be common among canister manufacturers, it’s worth inquiring about the CO2 sources. This transparency encourages companies to adopt more sustainable practices.
