I believe formaldehyde in manufactured boards has been banned in the EC for a long time. They use instead casein, a natural product, made from milk. It has been around for a very long time. It's good. Some years back a mosquito fighter bomber was found under one of the inland seas or polders in Holland. It had been under sea water for 60 or 70 years, since going down in the Second World War. Its casein glue joints were stronger than when it was built. These light wooden frame ground support planes had wooden frames,with casein as the glue.
It has no nasty out gassing and is very strong and water resistant. Formaldehyde is not great in comparison to it.
manufacturers like formaldehyde because its a bit cheaper and the manufacturing plants are cheaper to build.
When indoor pollution is worse than outdoor, which is the usual case, why not advocate the elimination of formaldehyde? It wont hurt the manufactrurers in the longer run. If non casein imports are banned, as I think they are in Europe, it could be a big plus. As well they could access export markets which will not accept formaldehyde products.
