Carbon emission calculator
With our climate calculator you can compare C02 emission for plastic parts made in Sweden with a no-name manufacturer in China, and also compare virgin raw material with recycled materials.
Estimation of CO2 footprint is made with the following assumptions:
Electricity production, Swedish electricity mix 13g C02 / kWh. If we assume that Mälarplast's machinery and a Chinese equivalent consume approximately the same electricity consumption per tonne of processed plastic, this means approximately 4 kWh / kg plastic (Mälarplast consumes 1200 MWh and processes 300 tonnes). This would then mean that Mälarplast gives rise to 4 kWh x 13 g = 52 g C02 per kg plastic. For Chinese production, it will be an average of 2.8 kg.
In general, measurements give that the production of the plastic raw material gives rise to 2 kg C02 per kg plastic. Then 1 kg plastic (PP / PE) gives 2 kg C02 during combustion.
