WHAT DOES THE BIOBASED PERCENTAGE ACTUALLY SAY?
You can actually measure the biobased content in the product itself. This can be done by means of carbon dating or 14C analysis. You can then determine a biobased content as a percentage of only the organic carbons in the paint (binders and solvents) or as a percentage of the total paint including pigments, fillers etc. A number of paint producers use the first method, the Total Organic Carbon percentage (TOC). Other producers, including Royal Van Wijhe Verf, choose the second method, the Total Carbon Percentage (TC). This way of calculation is controllable for everyone. And we like to be transparent about the sustainable properties of paint.
