Instead of importing considerable quantities of arsenic to Europe, it would be sensible to utilize the arsenic recovered in the recycling process in the manufacture of CCA-wood, in the metallurgical industry as well as in other ways. When copper is also processed into a form easy to
utilize, it may be possible to utilize chrome as well. When these developments are implemented, it can be said that CCA-treated wood is an ecologically sound product. When the recycling process is introduced in Europe on a large scale, an amount of energy equivalent to a nuclear power unit can be conserved.
