t. Thus, this paper studies composting as treatment method for the sustainable management and
recycling of the municipal solid wastes generated in the Chimborazo Region (Ecuador), and the use of
some of the composts obtained as growing media for seedling production. For this, six piles were
elaborated using municipal solid wastes: Piles 1, 2 and 3 were prepared using municipal solid wastes
from the Riobamba landfill and Piles 4, 5 and 6 were elaborated using source-separated market waste
and urban pruning wastes.
