Summary
Functional unit: 
1 kg of liquid paint
Goal and scope of the summary: 
The “Lifecycle Assessment of Paint” project has had three objectives. • To build up a knowledge database about paint and its raw materials. • To disseminate knowledge about the way paint influences the environment throughout its enti- re lifecycle. • To create basic data for developing more envi- ronmentally-adapted products, from a holistic perspective. The unit can be used for reporting on the environmental loading of the surface treatment system, up to and including the paint factory gate. The energy consumption and solvent emissions that occur during the application of the paints and which are of greatest importance from a lifecycle perspective, are not reported with this choice of functional unit. Transportation is, in all cases, negligible, which is why there is no particular comment on this. Note that the solvent’s environmental effect is not dominant in the preparation of raw material and production since the solvents only evaporate once the paint is used.

The most important conclusions are summarised below. • It is environmentally advantageous to extend
the working life of products by surface-treating them with paint.
• For solvent-based paint, the solvent, binding agent, pigment and manufacture are responsible for approximately equal proportions of environ- mental loading within the different areas of gre- enhouse effect, low-level ozone, acidification and eutrophication.
• For powder paint, the picture is more diffuse - the greenhouse effect is affected most by bin- ding agents. Low-level ozone originates mainly in the binding agents and the eutrophication effect is caused almost entirely by filler.
• In all cases, transportation accounts for negli- gible environmental loading

The general conclusion of the study is that the greatest part of the environmental impact originates in the actual object which has been painted in most cases, e.g. shelf, kitchen cabinet doors or timber weatherboarding. This applies to most categories for environmental impact. At the same time, the paint’s environmental impact cannot be ignored when the environmental impact of a surface-treated product is analysed.

The functional unit doesn't

The functional unit doesn't define the function with great accuracy. Something like the square meter of painted surface seems mors relevant.


Thanks for sharing the

Thanks for sharing the review! If I'll ever consider refacing bathroom cabinets I'll give it a serious thought, for the moment installing the single bathroom vanities is the priority. I knew before about the hazards of paint but I didn't know how important this is for health and environment. This article is an eye opener.
