“…The final pH of A and B was 8.20 and 7.90, respectively. Similar pH profiles after natural zeolite addition were also reported by Turan and Ergun (2008) and Villaseñor et al (2011), and they both found that pH decreased due to the natural zeolite addition to the municipal solid waste composting. As for reactor C (DMPP addition), the pH profile was similar to reactor A.…”

“…The dewatered sewage sludge and the spent mushroom were mixed manually at a ratio of approximate 1:3 (v/v), and then, the mixture was divided equally to the three reactors at about 45 kg each (wet weight). After that, natural zeolites were added at a ratio of 1 % wet weight as previously suggested (Venglovsky et al 2005;Villaseñor et al 2011) to reactor B, and DMPP was added in the form of stock solution (25 %, w/v) to reactor C at a final concentration of 1 % according to the total nitrogen (TN) content as usually used in land application (Yang et al 2013;Maienza et al 2014;Yu et al 2014). Reactor A was treated as the control.…”

“…In this process, organic matter is transformed into mature compost (stable and pathogen-free product) which is then used as a soil additive (Villaseñor et al 2011). This may be the least energy consuming and the most cost-effective means of sludge disposal or utilization.…”

“…Natural zeolite is a kind of mineral with an open reticular structure which allows the entrapment or release of various cations as a consequence of cation exchange reactions and adsorption (Venglovsky et al 2005). The ability of natural zeolite to the retention of NH 3 during sludge composting has been widely investigated (Bernal et al 1993;Venglovsky et al 2005;Villaseñor et al 2011;Zuokaite and Zigmontiene 2013), and several influences of natural zeolite including increasing sludge porosity (Stylianou et al 2008), affecting both its temperature and moisture (Venglovsky et al 2005) and reducing heavy metals concentrations (Villaseñor et al 2011), have been demonstrated. However, there is still little information on organics degradation during sludge composting after natural zeolite addition.…”

Sludge composting is one of the most widely used treatments for sewage sludge resource utilization. Natural zeolite and nitrification inhibitor (NI) are widely used during composting and land application for nitrogen conservation, respectively. Three composting reactors (A-the control, B-natural zeolite addition, and C-3,4-dimethylpyrazole phosphate (DMPP) addition) were established to investigate the influence of NI and natural zeolite addition on organics degradation and nitrogen transformation during sludge composting conducted at the lab scale. The results showed that, in comparison with the control, natural zeolite addition accelerated organics degradation and the maturity of sludge compost was higher, while the DMPP addition slowed down the degradation of organic matters. Meanwhile, the nitrogen transformation functional genes including those responses for nitrification (amoA and nxrA) and denitrification (narG, nirS, nirK, and nosZ) were quantified through quantitative PCR (qPCR) to investigate the effects of natural zeolites and DMPP addition on nitrogen transformation. Although no significant difference in the abundance of nitrogen transformation functional genes was observed between treatments, addition of both natural zeolite and DMPP increases the final total nitrogen content by 48.6 % and 23.1 %, respectively. The ability of natural zeolite for nitrogen conservation was due to the absorption of NH 3 by compost, and nitrogen conservation by DMPP was achieved by the source reduction of denitrification. Besides, it was assumed that the addition of natural zeolite and DMPP may affect the activity of these genes instead of the abundance.

BACKGROUND The growth of poultry farming has increased the amount of chicken manure (CM) being produced. In this study, CM was digested in a two‐stage anaerobic digestion (AD) system consisting of three leach bed reactors (LBRs) and a continuous stirred tank reactor (CSTR) coupled with sedimentation tanks (anaerobic contact process). The accumulated biomass and supernatant from the sedimentation tank were returned to the CSTR and the LBRs, respectively, resulting in an almost closed (water) circuit process. In addition, zeolite was used as bulking agent and adsorbent for ammonia in the LBRs. RESULTS This study revealed that the methane yield remained on average at 0.17 NL g−1 of Volatile Solids (VS), corresponding to the 43% of the CM biochemical methane potential as determined in separate batch tests (0.40 NL g−1 VS). Electrical conductivity gradually increased from 22 to 26 mS cm−1; however, the ammonia nitrogen concentration was stable at 2.28 g L−1, which was attributed to zeolite used as LBRs' bulking agent. A preliminary design of a full‐scale LBR‐CSTR facility was conducted for a poultry farm growing one million broilers per year. Its CO2 footprint was evaluated based on literature indices. CONCLUSION The proposed facility has a capacity of 130 kW Combined Heat and Power (CHP) and a payback period of 8.6 years. In terms of GHG emissions, implementing the LBR‐CSTR system for biogas production could potentially reduce the CO2 footprint of the farm from 1.38 to 0.49 kg CO2 eq/head. © 2022 Society of Chemical Industry (SCI).
