“…These values are consistent with Adhikari et al (2013) which reveal specific emission factors, according to the home composting system adopted such as: unmixed ground pile (115 kg CO 2 -eq), mixed ground pile (129 kg CO 2 -eq); plastic bin (83 kg CO 2 -eq), wood bin (126 kg CO 2 -eq).…”

“…The paper examines the role of plastic bins in the home composting process as a reliable alternative compared to open piles technique in 2012. Adhikari et al (2013) stipulated an emission factor of 83 kg CO 2 -eq t -1 ww based on the plastic bin. The net flux of GHG's is 18.5 kg CO 2 -eq t -1 taking into consideration the indirect downstream (-64.5).…”

Abstract. The paper examines the biowaste management issues across rural areas of Romania in the context of poor waste management infrastructure in the last decade (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012). Biowaste is the main fraction of municipal waste, thus a proper management is a key challenge in order to sustain a bioeconomy in the near future. The amount of biowaste generated and uncollected by waste operators is generally uncontrolled disposed if not recovered through home composting. The paper points out the role of home composting in diverting the biowaste from wild dumps and landfills for the regions covered or not by waste collection services. Home composting and the biowaste losses are further assessed based on several scenarios (worse-case, pessimistic, realistic, optimistic) where the net loads of greenhouse gasses (GHG) are calculated at national and regional levels. The transition of home composting techniques, from open piles to plastic bins with respect to standard guidelines will improve the home composting performance in terms of compost quality and net GHG's savings, supporting a bio-based economy which will lead towards a sustainable rural development. Regional disparities are revealed across Romanian counties and the paper opens new research perspectives regarding which options should be adopted by counties and rural municipalities in the biowaste management process.

“…Further, the major fractions of the municipal and industrial wastes ultimately end up untreated and/or partially treated into the landfills; which are the greatest sources of GGE in waste management and have now become exclusive. It has been accounted that about 12% (i.e., 734 kg CO 2 ‐eq/ton wet waste treated) of annual CH 4 emissions are contributed by landfill sites globally . Moreover, unseemly waste decomposition results in the release of about 61 Tg CH 4 /year that constitute nearly 17% of total global CH 4 emissions .…”

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.

“…One of the particular characteristics of the organic material fraction-considering the wet fraction of the waste, as in cooked food scraps and leftovers of fruits and vegetables-is its degradation on a short period of time, that is, if it is not controlled it can intensify environmental problems (Colón et al 2010). On the other hand, when composting is applied as a specific destination for organic matter, from a well-conducted degradation process, great advantages are obtained because there is no generation of slurry and greenhouse gases that are issued in lower concentrations than in dumping grounds, except for the organic fertilizer production at the end of the process (Adhikari et al 2013). According to Radwan et al (2010), composting represents a suitable option for recovering organic waste in a hotel, so it is necessary that local authorities support companies to make composting in their own backyard with sufficient tools and information.…”

The large influx of tourists worldwide as well as the expansion of tourism events increase the environmental impact caused by hotel services. The aims of this work were to characterize the solid waste generated by hotel sectors, and to compare that waste generation between different events organized in the enterprise. The data collection was performed using qualitative and quantitative characterizations, where the waste generation in each sector and the type of event organized, were registered. The results showed that most residues were found in the kitchen, bathrooms, rooms, and at the event hall, with higher values being generated in the festive events. The waste generation by these events corresponded to 48 % of the total generated in the lodging, while 8 % corresponded to the business events. The difference between the characterization of waste generated in festive events and that of business events, along with no occurrence of event at all, showed that it could be attributed to the increase in the per capita generation of categories of waste, primarily glass. The results obtained in this study are essential to the creation and/or improvement of a management plan of solid waste in lodging facilities.Palabras clave: industria del turismo, gestión ambiental, residuos sólidos municipales, composición gravimétrica RESUMEN El gran flujo de turistas en el mundo, así como el incremento de los eventos turís-ticos aumentan los impactos ambientales causados por los servicios hoteleros. Los objetivos de este estudio fueron la caracterización de los residuos sólidos generados por los sectores de un hotel y su comparación con la genereación de residuos en los diferentes eventos organizados en la empresa. La recopilación de datos se hizo a través de caracterizaciones cualitativas y cuantitativas, en las que se registraron la generación de residuos en cada sector y los tipos de eventos ocurridos. Los resultados mostraron que la mayoría de los residuos se generan en la cocina, baños, habitaciones y en la sala de recepción del evento, con valores más altos en los eventos festivos. La generación de residuos por el servicio de eventos correspondió al 48% del total Rev. Int.
