Abstract

The World Health Organisation and the World Bank present reviews of products available to replace asbestos-cement construction materials and other asbestos products. The product research includes information on providers of alternative products and substitute synthetic and natural fibres.

Hazard Assessment

Substance to be substituted: All asbestos types are listed in the database of hazardous substances according to SUBSPORTplus screening criteria (SDSC) as carcinogens. Alternative substances: The alternative substances mentioned in this case story are not listed on SDSC. However, other alternatives are mentioned in the report for which no hazard assessment could be performed. » Check the Substance Database according to SUBSPORTplus Screening Criteria (SDSC)

Description of Substitution

According to the reports the substitute construction products consist of fibre-cements made with polymeric or plant fibres or a combination of these, as well as completely different product compositions that serve the same functions as asbestos-cement sheets, pipes, and water storage tanks. The main materials used as alternatives are polyvinyl alcohol (PVA), cellulose, polypropylene fibres (PP) as well as PVA-cellulose and PP-cellulose. Other alternatives for asbestos-containing products are mentioned in the reports. Costs for producing fibre-cement sheets from polymeric fibres (polyvinyl alcohol or polypropylene) combined with cellulose are 10-15% higher. Some of the substitute products such as micro-concrete tiles are cheaper than asbestos-cement, and can be made in a basic workshop near the building site with locally available small contractors and materials (sand, gravel, and cement), lowering transport costs. Therefore, non-asbestos fibre-cement panels are lighter, less brittle, and have improved nailability over asbestos-cement sheets. Compared with asbestos-cement pipes, iron pipes can be transported with less difficulty and breakage, take greater compression loading, and last longer.

Case/substitution evaluation

The International Agency for Research on Cancer (IARC) has evaluated the carcinogenic potential of substitutes for chrysotile asbestos. The alternative materials polyvinyl alcohol, cellulose and polypropylene have not carcinogenic properties.
