  • effects of woody peat and superphosphate on Compost Maturity and gaseous emissions during pig manure Composting
    Waste Management, 2017
    Co-Authors: Difang Zhang, Jing Yuan, Guoxue Li
    Abstract:

    This study investigated the effect of calcium superphosphate on Compost Maturity and gaseous emissions during pig manure Composting with woody peat as the bulking agent. Two treatments were conducted with or without the addition of calcium superphosphate (10% dry weight of the Composting mass), which were denoted as the control and superphosphate-amended treatment, respectively. Results show that the Composting temperature of both treatments was higher than 50°C for more than 5days, which is typically required for pathogen destruction during manure Composting. Compared to the control treatment, the superphosphate-amended treatment increased the emission of nitrogen oxide, but reduced the emission of methane, ammonia and hydrogen sulfide by approximately 35.5%, 37.9% and 65.5%, respectively. As a result, the total greenhouse gas (GHG) emission during manure Composting was reduced by nearly 34.7% with the addition of calcium superphosphate. The addition of calcium superphosphate increased the content of humic acid (indicated by E4/E6 ratio). Nevertheless, the superphosphate-amended treatment postponed the biological degradation of organic matter and produced the mature Compost with a higher electrical conductivity in comparison with the control treatment.

  • effects of phosphogypsum and superphosphate on Compost Maturity and gaseous emissions during kitchen waste Composting

    Abstract:

    Highlights: • Effect of phosphogypsum and superphosphate on Composting gas emissions was studied. • The reduction mechanisms of Composting gas were clarified in this study. • No negative effect was caused on Maturity with phosphogypsum and superphosphate. • CH{sub 4} and NH{sub 3} emission was decreased with phosphogypsum and superphosphate addition. • GHG decreased by 17.4% and 7.3% with phosphogypsum and superphosphate addition. - Abstract: This study investigated the effects of phosphogypsum and superphosphate on the Maturity and gaseous emissions of Composting kitchen waste. Two amended Compost treatments were conducted using phosphogypsum and superphosphate as additives with the addition of 10% of initial raw materials (dry weight). A control treatment was also studied. The treatments were conducted under aerobic conditions in 60-L reactors for 35 days. Maturity indexes were determined, and continuous measurements of CH{sub 4}, N{sub 2}O, and NH{sub 3} were taken. Phosphogypsum and superphosphate had no negative effects on Compost Maturity, although superphosphate inhibited the temperature rise in the first few days. The addition of phosphogypsum and superphosphate drastically reduced CH{sub 4} emissions (by 85.8% and 80.5%, respectively) and decreased NH{sub 3} emissions (by 23.5% and 18.9%, respectively). However, a slight increase in N{sub 2}O emissions (by 3.2%more » and 14.8%, respectively) was observed. Composting with phosphogypsum and superphosphate reduced total greenhouse gas emissions by 17.4% and 7.3% respectively.« less
