Specifying eco-paints

Eco-paints offer an alternative to natural paints, but how green are they really? asks Hattie Hartman

Over the last five years, conventional paint manufacturers have improved the sustainability of their products, and a niche market of eco and natural paints has developed. The environmental impact of paint centres on its embodied energy, VOCs (Volatile Organic Compounds) emitted during its lifetime, and waste disposal.

Natural paints – those made from natural materials – are distinguished from ecopaints, which seek to reduce their environmental impact. Durability is also important.

The composition of paints is well-documented in Lynn Edwards’ Handbook for Eco Paints and Finishes (Eco-Logic, 2008). Titanium dioxide, the pigment often used for opacity, is the main culprit when it comes to embodied energy, while synthetic solvents such as white spirit emit VOCs.

The second phase of the EU directive, which sets emission limits for VOCs, will go into effect in 2010. Manufacturers are scrambling to comply. The trend is away from solvents towards water-borne paints.  

Transparency of labelling is key. Auro, Earthborn and Biofa list all their ingredients
on the tin.

Although ecopaints are more expensive, 90 per cent of the cost of painting is labour. Ordering lead times, on-site mixing requirements, and drying times drive the contract price up, not the cost of the paint itself.
