Résumé : |
Quality and costs were traditionally the main factors in the paint industry. Today also environmental considerations have become more and more important. In view of existing and announced environmental legislation the reduction of volatile organic compounds is one of the main driving forces of product development. There is no doubt that reduction of VOC content is important. However, it is doubtful if this is the best means of evaluating the environmental effect of new systems. In the authors' opinion an integrated chain evaluation or life cycle analysis is a better way.
In 1989 the Dutch Government announced in their National Environmental Policy Plan the intention to develop a method for the evaluation of the environmental effects of new products. These 'Eco-yardsticks' were developed by TAUW Infra Consult and published in 1991. The method embodies eight main sections :
1. Raw materials
2. Energy
3. Emissions
4. Nuisance
5. Waste
6. Re-usability
7. Respairability, and
8. Lifespan
These main sections are subdivided in twenty-five sub headings, such as exhaustion of non-renewable raw materials, emissions of acidifying compounds and chemical waste.
Decorative paints were one of the product groups by which the method was investigated during 1992. Four different paints were studied and evaluated for the relevant sub headings. Surprisingly the acrylic dispersion-based paint performed worst in the life cycle analysis. This was unexpected as these paint systems contain mainly water-based as solvent. The results of the study have been presented to the paint industry by Bancken and Geurink. Their main conclusion was that this integrated chain approach, based on the 'Environmental Measures', offers a sound basis for the evaluation of the environmental effects of different products. This paper describes subsequent investigations into this subject, including alkyd emulsions and clear varnishes. |
