Abstract
During studies on ‘Refuse Recycling Processes in Karachi’ for the United Nations Centre for Human Settlement (UNCHS-Habitat), a chemical evaluation of organic putrescible matter, a major component of recyclable materials, was carried out. The average putrescible matter (after sorting) had pH 6·1; moisture 39·5%; organic matter 56%; carbon 34%; nitrogen 1·2%; and C/N 28. These figures are in conformity with the optimum values needed for aerobic composting and hence this portion of refuse is a suitable material for bioconversion.
