“…After the compost mass and moisture content were obtained, specified amounts of TW and TL were supplied to create a suitable moisture condition (50%e55%) for compost decomposition. Thirdly, to be consistent with pilot-scale composting (as shown in Wu et al 2011), the composting period and surrounding temperature of the fermentation cylinder were tightly controlled. A fermentation period of 15 d, in accordance with the retention time of the compost in pilot-scale composting channel, was chosen for this study.…”

“…Typical values of the Q 4/6 ratio for humified material are usually lower than five (Gieguzynska et al 1998). Therefore, these values suggested that: (1) humification was not completed in both treatments and may need the second step of fermentation as described by Wu et al (2011); (2) typical values of the Q 4/6 ratio for humified material were evaluated by using humic acids from eroded soils. However, compost organic matter in stable and matured compost might differ from natural organic matter in soils (Gieguzynska et al 1998;Zbytniewski, Kosobucki, Kowalkowski, & Buszewski, 2002).…”

“…There are some ways which can be used in reducing NH 3 emission such as using biofilter (Wu et al, 2010;Utomo et al, 2010). Biofilter has been successfully conducted by Nanda, et al (2012) implemented the biofilter in the composting process to remove ammonia and volatile organic compound (VOC).…”

The process of aerobic composting the slaughterhouse (SH) solid waste generate ammonia emissions. Aim: The objective of this research to study the ability of the adsorbent to use zeolite to reduce ammonia gas emissions during the composting process of SH solid waste. Methodology and Results: Reduction of ammonia emission is conducted during the aerobic composting process which is 50 days. The raw material composition of the composting process used was 100% rumen contents, 60% rumen contents: 40% straw, 50% rumen contents: 50% straw, and 40% rumen contents: 60% straw. Zeolite used in the form of granular size 100 mesh. The result of the research showed that the level of release of ammonia gas emissions during the composting process could be reduced by zeolite. Conclusion, significance, and impact study: The efficiency of reducing ammonia gas emissions using zeolite adsorbents in the composting process of SH solid waste ranges from 98.09 - 99.40% on average. Zeolite is an adsorbent that has high adsorption power because it has many pores and has a high ion exchange high capacity and serves as an absorbent cation that can cause environmental pollution.

“…During composting, 9.6-46% of the initial TN loss of raw materials is in the form of NH 3 emissions (Jiang et al, 2011). Most previous studies have reported that NH 3 emission increases with increasing aeration rates (Jiang et al, 2011;Shen et al, 2011;Wu et al, 2011). This suggests that the aeration rate has a significant influence on the production and emission of NH 3 (Ahn et al, 2011;Shen et al, 2011).…”

Composting is a controlled biological process used to stabilize and transform waste into a soil treatment. Aeration rate is one factor that controls the process of composting, as it ensures the growth of adequate aerobic microbe populations. To investigate the effect of aeration rates on the physicochemical indexes of compost and the loss of nitrogen content during composting, aerobic composting processes with different aeration rates (A: 0.2 L/min/kg TS, B: 0.05 L/min/kg TS and C: 0 L/min/kg TS) were studied. Ammonium-nitrogen, nitrate nitrogen, total nitrogen and other factors in compost samples from different periods were measured. The results showed that aeration rate significantly affected O2 content under different conditions. The aeration rate also significantly affected water content, nitrate nitrogen, and nitrogen loss. NH3 emissions increased as aeration rates increased at high temperatures owing to nitrogen loss. These results showed that aeration rate had a significant effect on total nitrogen and ammonia emissions (p<0.05). Thus, optimization of the ventilation method could significantly increase seed germination rate.
