I am currently evaluating my ecobrick activity. I created this Ecobrick by compressing plastic packaging waste into a bottle to a certain weight, for that, I want to calculate how much carbon I have stored so far. The carbon calculation formula that I refer to is still based on the IPCC which is sourced from carbon emissions of the incinerator when the plastic is burned. But in my opinion, each type of plastic will have its own combustion speed and will produce different carbon dioxide emissions.
