Management of Urban Organic Solid Waste Applied in Romanian Metropolitan City

This paper explains the interest in urban organic solid wastes, the relevance of these wastes to municipal solid waste management, the main ways in which organics are reused, and the problem that arise from the wish to ensure safe and effec�tive reuse as part of sustainable development in cities in Romania. Wastes are substances resulting from biological or technological processes that can no longer be used as such, some of which are reusable. Dangerous substances are any substance or product which, when used in apparently non-hazardous quantities, concentrations or conditions, presents a significant risk to humans, the environment or material goods (eg explosives, oxidizing, flammable, toxic, harmful, corrosive, irritant, mutagenic. Urban administrations nowadays are seeking ways to divert organic wastes from municipal solid waste streams for a variety of reasons, as noted below. Recommenda�tions are made for separation at source so that safe composting can be carried out. Private companies are being encouraged to undertake composting, often via forms of public-private partnerships. More attention is being paid to the role of non-govern�mental organizations in promoting citizen awareness of organic waste issues, and co-operation with separation at source. This paper draws attention to the many informal ways that organic wastes are currently reused, which are rarely taken into account in official plans for managing organic wastes.

Organic Fraction

With the implementation of new policies supporting renewable natural gas production from organic wastes, Canada began replacing traditional disposal methods with highly integrated biogas production strategies. Herein, data from published papers, Canadian Biogas Association, Canada’s national statistical agency, and energy companies’ websites were gathered to gain insight into the current status of anaerobic digestion plants in recovering energy and resource from organic wastes. The availability of materials prepared for recycling by companies and local waste management organizations and existing infrastructures for municipal solid waste management were examined. Governmental incentives and discouragements in Canada and world anaerobic digestion leaders regarding organic fraction municipal solid waste management were comprehensively reviewed to identify the opportunities for developing large-scale anaerobic digestion in Canada. A range of anaerobic digestion facilities, including water resource recovery facilities, standalone digesters, and on-farm digesters throughout Ontario, were compared in terms of digestion type, digester volume, feedstock (s), and electricity capacity to better understand the current role of biogas plants in this province. Finally, technology perspectives, solutions, and roadmaps were discussed to shape the future in terms of organic fraction municipal solid waste management. The findings suggested that the biogas industry growth in Canada relies on provincial energy and waste management policies, advanced technologies for diverting organic waste from landfills, improving biogas yield using existing pretreatment methods, and educating farmers regarding digester operations.

The City

This study assessed the current status of solid waste management (SWM) in the City of Kigali (CoK), the capital city of Rwanda. This assessment was done using systems analysis methodology of “wasteaware” benchmark indicators for integrated sustainable waste management in cities. This method of assessing helps to assess the Municipal Solid Waste Management (MSWM) in a city according to its physical components and governance features. Data were collected during a 6-month period from May to October 2017, but verification took other four months (Up to February 2018). Data were obtained from official reports, legal documents, and interviews with key personnel and operators and also from official and unofficial dumpsites visits. In CoK, approximately 232,870 tons of MSW is generated per year, MSW collection and transportation is done by private companies but the only dumpsite present in Kigali is fully controlled by the City of Kigali. Residents pay waste collectors according to their social classes and their locations. There is no official recycling system; recycling activities are informally performed by private companies and some wastes, like plastic bottles, are taken to Uganda and Tanzania to be recycled. This study found that the recycling rate was 10% contrarily to the 2% which is recorded by official sources. This study has contributed by filling the gap in literature on waste management for the city of Kigali and it recommends that the Government represented by the CoK should do more in terms of investing in SWM and creating a relationship between private waste collectors and local communities, and the private sector should be mobilized to invest in SWM activities.

Emission Of Greenhouse Gases

The technology of anaerobic digestion of organic solid wastes is, in many aspects, mature. Topics such as fundamentals (kinetics, modeling, etc...) Process aspects performance, two and single phase systems, wet technologies, digestion enhancement of several treatments. Digestion with other substrates and its relation to composting technology are examined in this review. Special attention is paid to the advantages of anaerobic digestion in limiting the emission of greenhouse gases. An overview of industrial achievements and future developments. Municipal solid waste management (MSWM) is one of the major environmental problems of Indian cities. Improper management of municipal solid waste (MSW) causes hazards to inhabitants. Various studies reveal that about 90% of MSW is disposed of unscientifically in open dumps and landfills, creating problems to public health and the environment. In the present study, an attempt has been made to provide a comprehensive review of the characteristics, generation, collection and transportation, disposal and treatment technologies of MSW practiced in India Special attention is paid to the advantages of anaerobic digestion in limiting the emission of greenhouse gases. On overview domestic and organic waste achievement and future development.

The Many

The disposal of municipal solid waste can be costly and environmentally destructive. This article asks why, given many alternatives, most waste material is still disposed of in landfills or incinerators. Building upon the ‘modes of governing’ framework proposed by Bulkeley, Watson, and Hudson as a means of identifying and interpreting the relationships among the many actors and artefacts that constitute a municipal solid waste management system, this article explores the barriers to transitioning between modes. The case of solid waste management in Boston, Massachusetts illustrates how key factors – limited enforcement of existing policy, institutional and physical fragmentation, financial incentives, and the vested interests of the private sector – protect the disposal mode of governing. Meanwhile, the actors most interested in moving towards more sustainable waste management techniques lack access to decision-making processes and daily operations, limiting their ability to influence policy and practice. The analysis of barriers suggests an alternative way of classifying modes – dominant, incremental, visionary, and aspirational – that explicitly captures the relative entrenchment of each mode, while also opening up the framework for application in other geographies, and for other systems that may or may not share similar governmental rationalities, technologies, or capacities.
