Survey of facilities operating in Catalonia provides data on technology (windrow or in-vessel), public vs. private ownership, feedstocks, and process characteristics. Older plants use windrows while more recent plants use an in-vessel process for the initial phase of the process. Plants that use in-vessel process are, in general, publicly-owned and they mostly process OFMSW. Plants that use windrows tend to process a wider range of residues. In-vessel processing is shorter and requires less labor. Operating capacity of windrow systems is closer to their nominal capacity, whereas in-vessel capacity is around 50 percent of their nominal one. Finally, the public does not oppose having the composting plants near their towns.
