The Circular and Co Returnable cup is designed to replace single use paper cups and after just 2 uses, the CO2 emission of the Circular Returnable Cup are offset versus a single-use alternative. This means that huge amounts of CO2 never reaches our atmosphere. People in the UK get through at least 2.5 billion disposable cups each year so switching to a returnable cup eliminates billions of cups from landfill. Both CO2 and operating costs will be reduced significantly by moving to a returnable cup to replace a single use version.
