Aerated Static Pile Composting for Industrial Biowastes: From Engineering to Microbiology

Characterization of Odorant Compounds from Mechanical Aerated Pile Composting and Static Aerated Pile Composting.

We studied airborne contaminants (airborne particulates and odorous compounds) emitted from compost facilities in South Korea. There are primarily two different types of composting systems operating in Korean farms, namely mechanical aerated pile composting (MAPC) and aerated static pile composting (SAPC). In this study, we analyzed various particulate matters (PM10, PM7, PM2.5, PM1, and total ...

2 Microbiology of Composting

Heavy metals fractionation during the thermophilic phase of sewage sludge composting in aerated static piles.

An aerated static pile system with temperature feedback control was used for the composting of sewage sludge amended with olive tree leaves in a 1:1 (SS1) and 1:2 (SS2) v/v ratio, on two different occasions. The two piles were approximate 20 m3 each of similar dimensions; 2.0 wide at the base, 1.3 m height and 11 m long. Samples were taken from the core of the piles on four occasions: day 0 (es...

Pile settlement and volume reduction measurement during forced-aeration static composting.

In this study, a settlement measurement device was used to track the settlement of different layers in composting piles, and time courses of settlement velocity, bulk density distribution, and effective bulk density were investigated. Settlement is divided into two stages: the physical compressive settlement and the mass loss settlement. At the end of the former stage, bulk density (rho') and p...

Air Emissions from In-Vessel Rotating Drum and Open Static Pile Composting of Swine Carcasses, Whole and Ground

Swine carcasses (292 ± 7.3 kg per batch), whole or ground, were composted using rotating drum in-vessel (IV) or open static pile (OSP) composting systems, in the 2 × 2 factorial designed experiment. Dairy manure compost, horse stall bedding, and dry wood shavings were mixed together (analyzed % H2O, % N, and C:N of 48.7 ± 0.32%, 0.76 ± 0.075%, and 31.8 ± 2.51, respectively) and added amendment ...
