“…The carbon mineralization of organic wastes follows a combined two-step kinetic: initial rapid phase1st-order followed by 0-order, slow phase [74], thus, the rationale to use of these two models to find kinetic parameters of composting. Results from this study confirmed that zero and 1st-order kinetic suits both for the production CO 2 and O 2 consumption (first stage of composting), which is confirmed with high R 2 and low AIC results (Tables S2.1 and S2.2, Supplementary Materials). CO 2 production and O 2 consumption rate during biotic conditions were typical for the first stage of composting, as were observed by other researchers [46,70,75].…”

“…Composting and aerobic biostabilization processes of biowaste are sources of CO production, besides major ones such as natural forest fires and incomplete fuel combustion and also through biochar production [2]. Production of CO is a result of the biological decomposition of organic matter, which also generates CO 2 , CH 4 , H 2 , nitrogen compounds, VOC, and H 2 S [3].…”

“…Production of CO is a result of the biological decomposition of organic matter, which also generates CO 2 , CH 4 , H 2 , nitrogen compounds, VOC, and H 2 S [3]. CO emissions have been observed during the composting of green waste [4], green waste with manure [5], organic waste [2], and aerobic biostabilization of the municipal waste [6]. The detection of CO during the pioneering experiments was a surprise due to the widespread belief in its primary production by incomplete combustion [7].…”

Knowledge of kinetic parameters of CO production during biowaste composting is significantly important for the prediction of its course and estimation of total gas quantity. This allows increasing the control of the process, to minimize its negative impact on the environment and to protect the occupational safety of employees exposed to CO in the biowaste composting plant. For the first time, a full study of the influence of temperature and biowaste sterilization on the kinetics of CO production is presented. The lab-scale experiments used a mixture of green waste, dairy cattle manure, and sawdust in two variants: sterilized and non-sterilized samples. The process was carried out in controlled temperature reactors with measuring the concentrations of CO, O2, and CO2 every 12 h.CO production and k value increased with temperature. However, higher CO production was observed in biotic conditions between 10~50 °C, suggesting the biotic CO formation and 1st-order kinetics. The abiotic (thermochemical) process was more efficiently generating CO above 50 °C, described with a 0-order kinetic model. Additionally, the rate constant (k) value of CO production under biotic conditions was increasing up to a temperature of 60 °C, above which a slight decrease in CO production rate was observed at 70 °C. The presented results are the basis for further studies focused on the feasibility of (1) the mitigation and (2) valorization of CO production during the biowaste biostabilization are warranted.

“…It has been demonstrated that fossil fuel combustion is the major source of nitrogen oxide (NOx) and black smoke (suspended particulate matter less than 15 µm) emissions [9]. Another pollutant produced through combustion is CO [10], one of the main contributors to air pollution due to its high toxicity [11]. Furthermore, sulfur-containing fossil fuel combustion is responsible for most of the sulfur dioxide (SO 2 ) content in the atmosphere [12].…”

Specific and Cumulative Exhaust Gas Emissions in Micro-Scale Generators Fueled by Syngas from Biomass Gasification

et al. 2021

Climate change, environmental degradation, and biodiversity loss are prompting production systems to shift from a fossil-based economy to a circular bio-based one. In this context, biomass gasification is a promising alternative to fossil fuels that can contribute to power generation in rural communities and remote areas as well as provide a sustainable source of energy for developed countries. In this work, exhaust gas emissions (CO, NOx, and SO2) of two syngas-fueled micro-scale generators were measured. The first system is a commercial biomass gasifier genset, whereas the second is composed of a laboratory-scale gasifier prototype and a portable petrol generator. For this second facility, emissions were measured both running on gasoline and on syngas. The comparison was performed both on the pollutant concentration and on their cumulative amount. This comparison was made possible by calculating the exhaust gas flow by knowing the combustion stoichiometry and fuel consumption. The results showed a much lower pollutant concentration running on syngas compared to gasoline. In particular, considering the best configurations, every cubic meter of exhaust gas released running on syngas contains about 20 times less CO and almost one-third less NOx compared to gasoline. Moreover, the cumulative amount of emissions released was also considerably lower due to the lower exhaust gas flow (about 25%) released running on syngas.
