“…Increase in temperature during the early phase of composting is an indicator of intensive decomposition. Similar results were observed by Liu et al () and Chen et al (). Zhang and Sun () attributed similar observations to an ideal initial C/N ratio of the substrate and good ventilation that fostered the composting process.…”

“…This reduced turnover was likely a consequence of the high biochemical stability of biochar-C (Awasthi et al, 2017), leading to lower cumulative emissions even with higher initial ones. These results were similar to those of Liu et al (2017) who observed a decrease in CO 2 emissions when bamboo biochar was added to compost. They attributed this reduction to sequestration of exogenous carbon by biochar.…”

Adding biochar to nutrient rich organic matter during composting reportedly reduces nitrogen (N) volatilization and carbonization of feedstock stabilized organic carbon (C). We studied the effects of biochar, produced from agricultural residue as compost additives, on CO2, N2O, and NH3 fluxes in northern Ghana. Three biochar types [from corn cobs (cCC), rice husks (cRH), and wood (cWO)] and their uncharred feedstocks (CC, RH, and WO), were co‐composted with poultry manure (15 vol.‐%) and rice straw (60 vol.‐%) in randomly allocated 1 m3 compost bins. Emissions were measured using a closed chamber system composed of a photo‐acoustic infrared gas analyser (INNOVA 1312‐5). Biochar amended composts showed higher CO2‐C emission rates during the initial composting phase. Maximum CO2‐C flux rates during the first week reached 15 g CO2‐C m−2 h−1 in cRH and 12 g CO2‐C m−2 h−1 for RH, while those from cCC were 19 g CO2‐C m−2 h−1 and from CC 14 g CO2‐C m−2 h−1. Respiration significantly dropped during the last week of composting and lower rates recorded with carbonized compared with the un‐carbonized feedstocks. Total CO2‐C losses were 12 kg m−2 34 d−1 for RH and 9 kg m−2 34 d−1 for cRH, resulting in a 29% reduction of CO2‐C. Emissions were 9 and 10 kg CO2‐C m−2 34 d−1 for cCC and CC, while cWO and WO emitted 7 and 8 kg CO2‐C m−2 34 d−1, respectively. Volatilization of NH3‐N was significantly lower in compost containing cWO (89 g N m−2 34 d−1) compared to WO (166 g N m−2 34 d−1), while N2O‐N emissions were lower in compost mixtures containing cRH (27%), cCC (7%), and cWO (16%) compared with their un‐carbonized feedstock.

“…The use of biochar in organic waste composting had attracted special interest in the last decade because it improved the compost value and enhanced the environmental and agronomical benefits. During 2016-2018, numerous studies have systemically evaluated the advantages of biochar on organic waste composting including accelerating organic matter degradation and humification (Jindo et al 2016;Zhang et al 2016b), enhancing microbial diversity (Liu et al 2017a;Sun et al 2016), reducing N losses (Agyarko-Mintah et al 2017b;Lopez-Cano et al 2016;Wang et al 2017e), reducing greenhouse gas emissions (Agyarko-Mintah et al 2017a;Awasthi et al 2016a;Chen et al 2017b), and reducing the bioavailability of heavy metals (Awasthi et al 2016a;Liu et al 2017b) and organic pollutants (Stefaniuk and Oleszczuk 2016). The most commonly used organic waste for composting was manure (see Fig.…”

Biochar is the carbon-rich product obtained from the thermochemical conversion of biomass under oxygen-limited conditions. Biochar has attained extensive attention due to its agronomical and environmental benefits in agro-ecosystems. This work adopts the scientometric analysis method to assess the development trends of biochar research based on the literature data retrieved from the Web of Science over the period of 1998-2018. By analysing the basic characteristics of 6934 publications, we found that the number of publications grew rapidly since 2010. Based on a keyword analysis, it is concluded that scholars have had a fundamental recognition of biochar and preliminarily found that biochar application had agronomic and environmental benefits during the period of 1998-2010. The clustering results of keywords in documents published during 2011-2015 showed that the main research hotspots were "biochar production", "biochar and global climate change", "soil quality and plant growth", "organic pollutants removal", and "heavy metals immobilization". While in 2016-2018, beside these five main research hotspots, "biochar and composting" topic had also received greater attention, indicating that biochar utilization in organic solid waste composting is the current research hotspot. Moreover, updated reactors (e.g., microwave reactor, fixed-bed reactor, screw-feeding reactor, bubbling fluidized bed reactor, etc.) or technologies (e.g., solar pyrolysis, Thermo-Catalytic Reforming process, liquefaction technology, etc.) applied for efficient energy production and modified biochar for environmental remediation have been extensively studied recently. The findings may help the new researchers to seize the research frontier in the biochar field.

“…The decomposition process can be accelerated by conditioning the composting process to be aerobic [4]. This is due to the presence of sufficient oxygen condition, so that aerobic bacteria can stay alive [5]. One way is to do stirring on the garbage pile [6].…”

Currently, Diponegoro University has been composting dry leaves with conventional methods through a facility called TPST. Even so, the processing which have been carried out has not been able to process all the organic waste in the location. Seeing these conditions, it is necessary to look for alternatives that are better and more economical to apply. Bioactivators are used from the leaves of Pterocarpus indicus which serve to accelerate the composting process. The bioactivators was made by making a solution of the leaves of Pterocarpus indicus which has been mashed, then mixed with molasses and rice flour and then left for 15 days. By using experimental method, the composting process is observed. This study aims to analyze the quality of compost with applicable standards. The quality of compost is assessed by looking at the pH, temperature, and macro nutrient percentage such as C-organic, N-total, and C / N ratio. During the composting process, variations in the stirring frequency are carried out, which is once every 2 days, 4 days and 7 days. After doing laboratory test, not all reactors meet the standards for pH, temperature, C-organic, N-total, and C / N ratio according to SNI 19-7030-2004.
