Potential Carbon Footprint Reduction for Reclaimed

A potential carbon footprint reduction of between 55% and 64% was found for one tonne of asphalt containing 93% RAP and produced at 105 °C compared to the 0% RAP mixture produced at 175 °C. Considering the uncertainty of this technology at its early stage of development, the reduction could be as low as 45% or as high as 79%.

2021-11-11  When this is done, the effect on the footprint of the new asphalt is that each 10% of reclaimed or recycled asphalt planings (RAP) added will save around 4% of total embodied carbon. Tarmac’s latest plants are capable of incorporating RAP at 50% of the mix, giving a 20% carbon saving in a standard hot asphalt product.

Greenhouse Gas Emissions from Asphalt Pavement ...

2016-3-22  While carbon dioxide is the GHG of greatest concern, there are several other GHGs. As the global warming potential (GWP) of these GHGs varies, a group of conversion coefficients are established to convert the emission of a specific GHG into carbon dioxide equivalents (CO 2 e). In this context, GWP is the integral of the global warming effect of a GHG compared with that of CO 2 in the same time ...

2017-12-1  The eutrophication potential of starch plastics is 3–5 times higher when using virgin starch, and 2–4 times when using reclaimed starch. For the most part, this impact is linked to biomass cultivation, although electricity use (compounding) and some petrochemical polymers (e.g. PBS) also contribute.
