The relevance of the TOC parameter becomes clear when look-

countries: the Waste Disposal Ordinance, the Waste Technical
Guidelines, the Landfill Ordinance, the Ordinance pertaining
to the Recovery of Waste, the Stowing Directive, the Drinking
Water Ordinance and the Waste water Ordinance are just some
that mention TOC as a valuable parameter.
