Papermills are confronted with another waste problem namely the sludge coming from the water purification plant. In our research we try to compost the sludge together with bark in order to obtain a product which is usable as a horticultural susbstrate. Composts can be made with sludge up to 50 per cent. After the composting experiments growth trials are carried out: Fatshedera, Aralia eglantissima, Dieffenbachia exotica, Vriesia splendens and Monstera deliciosa. The growth of these plants is as good in the bark-sludge compost as in the classical substrates so we can conclude that these new mixtures can be used as horticultural substrates.
