Nitrogen-retaining property of compost in an aerobic thermophilic composting reactor for the sanitary

Fan BAI, Xiaochang WANG,

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 2,   Pages 228-234 doi: 10.1007/s11783-010-0022-7

Abstract: Aerobic composting is a method for the sanitary disposal of human feces as is used in bio-toilet systemsAs the products of composting can be utilized as a fertilizer, it would be beneficial if the compostingIn this study, batch experiments were conducted using a closed aerobic thermophilic composting reactorof NH–N was accompanied by the accumulation of NH gas in the ammonia absorber connected to the reactorThermophilic composting could be considered as a way to keep a high organic nitrogen content in the compost

Effect of lime on speciation of heavy metals during composting of water hyacinth

Jiwan SINGH,Ajay S. KALAMDHAD

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 1,   Pages 93-102 doi: 10.1007/s11783-014-0704-7

Abstract: Composting is attractive and inexpensive method for treatment and biomass disposal of water hyacinth.However, the major disadvantage of water hyacinth composting is the high content of heavy metals in theStudies were carried on composting of water hyacinth ( ) with cattle manure and sawdust (6:3:1 ratio)Results showed that, the total metal content was increased during the composting process.Addition of lime was very effective for reduction of bioavailability of heavy metals during composting

Greenhouse gas emissions during co-composting of cattle feedlot manure with construction and demolition

Xiying Hao, Francis J. Larney

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 3, doi: 10.1007/s11783-017-0955-1

Abstract: This research investigated greenhouse gas (GHG) emissions during cattle manure stockpiling or compostingDG manure) had no effect on GHG emissions over the 99 day manure composting or stockpiling.Composting with C&D waste produced similar CO emissions, about double that from manure stockpiling (Additionally, only 0.48% of C was emitted in CH form with C&D waste, compared to 1.68% when compostingThe lower CH emissions with C&D waste are beneficial in reducing overall GHG emissions from manure composting
