 Once the CO2 level had stabilized, the

foam samples were added to the bioreactors and mixed with the activated compost

 Green compost was placed in a closed glass

bioreactors for 4 to 5 days at 58°C and 70–80% RH for biological activity renewal (CO2)

 The

cumulated CO2 released by microorganism was detected by an infrared gas analyzer
