“…Similarly, high activities of methanogens (Ermolaev et al, 2014) and subsequent CH4 emissions (Vu et al, 2015) have been reported during the thermophilic stage. Controlling pH through the use of additives (Awasthi et al, 2016), lowering mineralisable C and/or increasing the substrate C : N ratio by the addition of a bulking agent (Santos et al, 2016;Wang et al, 2014) reduce N losses and GHG emissions. However, these practices are difficult to scale up to largescale systems, particularly in non-mechanised agricultural systems.…”

“…They also affect N transformations such as mineralisation, volatilisation, nitrification and denitrification through their interaction with associated microbes (Velasco-Velasco et al, 2011;Wang et al, 2014). Hence, earthworms could influence N losses and GHG emissions during composting.…”

“…Little is known about N losses and GHG emissions during vermicomposting (Lim et al, 2016), and the literature is contradictory. For instance, Wang et al (2014) found that earthworms reduce GHG emissions during vermicomposting. Other studies have shown that earthworms induce N2O emissions (Hobson et al, 2005) because their gut contains denitrifying bacteria.…”

Greenhouse Gas Emission During Composting and Vermicomposting of Organic Wastes – A Review

Human‐induced climate change, mainly through greenhouse gases emission (GGE), is attracting attention worldwide and has become one of the major threats to the environmental sustainability. Utmost is the need to understand the impact of waste management practices on GGE, or countries could incorporate alternative waste management strategies for various organic wastes. Strict regulatory controls limiting waste disposal in landfills and the consequent diversion of biodegradables have resulted in the adoption of sustainable waste management techniques like composting and vermicomposting. However, composting and vermicomposting systems for waste management, especially at large scale have the capacity to emit high levels of greenhouse gases (GHGs). This paper reviews the current available literature pertaining to GGE during composting and vermicomposting of various organic wastes, linking with the fate of carbon (C) and nitrogen (N) during stabilization. Further, the current study provides a comprehensive summary of the emissions and plausible mechanisms and factors responsible for the GGE during both processes. The article also highlights likely mitigation actions relating to process parameters effective in minimizing GGE during composting and vermicomposting of organic wastes.

The growing demand for environmental protection and sustainable food production requires the efficient use of organic and slow‐release fertilizers in agriculture. In this study, co‐composting of municipal solid waste (MSW) + three different ratios of natural and Mg‐modified zeolites (5, 10, and 15% on a wet weight basis) is conducted to improve the MSW compost quality. The effects of soil amendment with MSW compost containing natural zeolite (CNZ) and Mg‐modified zeolite (CMZ) on the corn yield, moisture content, leaching volumes, and NO3‐N concentrations are investigated. Compared to the control (zeolite‐free compost), the CNZ15 and CMZ15 treatments show 39.9 and 49.3% reduction in electrical conductivity and an increase of 64.5 and 110% in NH4‐N retention, respectively. By using the composts containing zeolite, the moisture content in the surface layer of soil is increased up to 12.6%. Nitrogen uptake and water use efficiency in the CNZ treatment are enhanced by 34.6 and 40.0%, respectively. The increase of the nitrogen uptake and water use efficiency of the CMZ treatment is 54.5 and 55.6%, respectively. Compared to the control, the amount of total NO3‐N leached from CNZ and CMZ treatments is decreased by 21.0 and 28.9%, respectively. The use of the MSW compost modified with Mg‐zeolite is, therefore, an environmentally friendly solution to prevent surface and groundwater pollution. The modified compost could be also used for the improvement of the physicochemical properties of sandy loam soils.
