Carbon Footprint Assessment of Di-Calcium Phosphate Production from the Tunisian Chemical Group

Increased industrial activities are highly linked to increased carbon emissions, which have been identified as the main cause of the increase of global warming and contribute of a substantial amount of greenhouse gases into our environment. As such, an average carbon footprint of di-calcium phosphate (DCP) production from the Tunisian Chemical Group has been calculated and analyzed. The model established using the SimaPro software considers for carbon footprint evaluation using the “IPCC GWP 2013 100 a V1.03” for the impact assessment methodology. The specificity of this method is to assess the “climate change” impact. This study showed that direct emissions contributing for 1350.1 kg CO2 eq/t of DCP which 64.96% is attributed to the synthesis reaction of (DCP), with a significant proportion of 46.14% of phosphoric acid used as a raw material. Natural gas contributes with a percentage of 32.6%of total GHG emissions. While, greenhouse gas emissions from transportation and electricity represents 1.2% of total emission.
