Summary, comments and additional information
Interpretation The majority of impacts associated with paint products relate to the materials that compose the paint itself (A1, Figure 1). This is expected and is consistent with other analyses of paint products whereby the actions of Crown Paints are the last of a supply chain of material production (i.e. energy inputs, raw materials use, processing). Crown Paints’ use of these materials is relatively small by comparison as the production site for these products only mixes existing materials into the final product. The most signif icant environmental impacts of Crown Paints’ products come from the use of titanium dioxide (pigment) and acrylic polymer (additive) as a raw material ingredients (Figure 2). These materials are used to create opacity and are used widely in all paint products. Depending on the colour of paint, the amount of titanium dioxide will vary and thus the range of impacts between shades can be significant. The variability of different pack sizes is negligible (Figure 3). It Is typical that titanium dioxide is the highest impact component of paint throughout its lifecycle as it has high impact intensity and can make up a high proportion of the paint formulation. All of the products assessed in this LCA have minimal impacts during the application stage of the product (A5, Figure 4). The majority of impacts occur in the application materials – such as drop sheets and rollers – and these impacts in reference to the functional unit of the study are quite small (Figure 1).
