composting as a climate change mitigation strategy, novel composting techniques are needed that can minimize the emission of greenhouse gases (GHGs) and NH 3 from solid manure while transforming this polluting waste into a valu-able organic resource. Biochar-composting is one strategy that has been re - cently proposed for reducing the

compost reactor, as a platform to study the potential impact of temperature, O2 concentration, airflow rate, and moisture content on the gaseous emissions from

2023/6/1/ · Section snippets SS composting plant. The industrial-scale BTF-FBF was applied in SS composting facility of a WWPT in Beijing, China. The SS composting facility has a total area of 12,000 m 2 and 150 tons SS (with moisture and organic content of 80% and 59%, respectively.) per day. The optimal porosity was achieved by combining SS

2009/4/6/ · Aims: To monitor emissions of NH 3 and N 2 O during composting and link these to ammonia oxidation rates and the community structure of ammonia oxidizing bacteria (AOB). and Results: A laboratory-scale compost reactor treating organic household waste was run for 2 months. NH 3 emissions peaked when pH started to

Gaseous emissions and the biological turnover of organic household wastes were studied under controlled conditions in a compost reactor (55°C, moisture content 65% w/w, O 2 concentration 16% in compost off-gas). During the first experiments, the temperature was increased to 55°C within 6 h using external heating. These experiments resulted in low

2012/1/1/ · The pilot-scale reactor was able to control the temperature and O2 concentration inside the compost using an automated control algorithm. FTIR spectroscopy was used to continually measure the

2018/1/9/ · The main variables (aeration, turning, and additive) on greenhouse gas (GHG) emission rates and spatial GHG concentrations in the pores of composting piles during the large-scale composting were

2015/12/1/ · Emissions of methane (CH₄) and nitrous oxide (N₂O) from composting of source-sorted food waste were studied at set temperatures of 40, 55 and 67 °C in 10 trials performed in a controlled environment 200 L compost reactor.CH₄ and N₂O concentrations were generally low.

2019/3/19/ · The final GI of the cylindrical reactor with an airflow rate of 0.3 L min −1 kg −1 DM was 82.3%, whereas the GIs of the other compost reactors were below 80%. In this study, compost of a cylindrical reactor with a low aeration rate (0.3 L min −1 kg −1 DM) was more stable and mature than the other reactors.

Mismanagement of the composting process can result in emissions of CH 4, N 2 O, and NH 3, which have caused severe environmental problems.This study was aimed at determining whether CH 4, N 2 O, and NH 3 emissions from composting are affected by bulking agents during rapid composting of pig manure from the Chinese Ganqinfen

2014/9/1/ · The emissions were even lower in the reactor studies, highlighting both the uncertainty when evaluating the possible direct emissions from composting and the possibility of emissions reduction
