‣ Fast thermophilic decomposition: piles are placed over an
aerated floor where pipes connected to a blower supply the air
needed for composting. Piles are turned <strong>and</strong> mixed every 3–4 days,
for one month, to homogenize the compost <strong>and</strong> promote rapid
oxygen transfer.
‣ Curing in outdoor windrows: to guarantee the necessary oxygen,
windrows are turned every 8–10 days. The area is paved <strong>and</strong>
leachate is collected.
‣ Screening: two sizes of screen are in use, the finer for compost to
be used for pot cultivation (< 10 mm), the other for agricultural
users. Coarse rejects are sent to l<strong>and</strong>fill.
Storage of the final product under a roofed area. In order to reduce the visual
impact, the border of the composting site has been provided with a vegetation
curtain. (Success stories on composting <strong>and</strong> separate collection., 2000)
