“…When the fossil fuel offset is also taken into account, the positive impact on GHG reduction can be even greater (e.g., Pipatti and Savolainen 1996, Lohiniva et al 2002, Consonni et al 2005. Because of the high capital costs, thermal processes are expected to be primarily deployed in developed countries.…”

Greenhouse gas (GHG) emissions from post-consumer waste and wastewater are a small contributor (about 3%) to total global anthropogenic GHG emissions. Emissions for 2004-2005 totalled 1.4 Gt CO2-eq year(-1) relative to total emissions from all sectors of 49 Gt CO2-eq year(-1) [including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and F-gases normalized according to their 100-year global warming potentials (GWP)]. The CH4 from landfills and wastewater collectively accounted for about 90% of waste sector emissions, or about 18% of global anthropogenic methane emissions (which were about 14% of the global total in 2004). Wastewater N2O and CO2 from the incineration of waste containing fossil carbon (plastics; synthetic textiles) are minor sources. Due to the wide range of mature technologies that can mitigate GHG emissions from waste and provide public health, environmental protection, and sustainable development co-benefits, existing waste management practices can provide effective mitigation of GHG emissions from this sector. Current mitigation technologies include landfill gas recovery, improved landfill practices, and engineered wastewater management. In addition, significant GHG generation is avoided through controlled composting, state-of-the-art incineration, and expanded sanitation coverage. Reduced waste generation and the exploitation of energy from waste (landfill gas, incineration, anaerobic digester biogas) produce an indirect reduction of GHG emissions through the conservation of raw materials, improved energy and resource efficiency, and fossil fuel avoidance. Flexible strategies and financial incentives can expand waste management options to achieve GHG mitigation goals; local technology decisions are influenced by a variety of factors such as waste quantity and characteristics, cost and financing issues, infrastructure requirements including available land area, collection and transport considerations, and regulatory constraints. Existing studies on mitigation potentials and costs for the waste sector tend to focus on landfill CH4 as the baseline. The commercial recovery of landfill CH4 as a source of renewable energy has been practised at full scale since 1975 and currently exceeds 105 Mt CO2-eq year(-1). Although landfill CH4 emissions from developed countries have been largely stabilized, emissions from developing countries are increasing as more controlled (anaerobic) landfilling practices are implemented; these emissions could be reduced by accelerating the introduction of engineered gas recovery, increasing rates of waste minimization and recycling, and implementing alternative waste management strategies provided they are affordable, effective, and sustainable. Aided by Kyoto mechanisms such as the Clean Development Mechanism (CDM) and Joint Implementation (JI), the total global economic mitigation potential for reducing waste sector emissions in 2030 is estimated to be > 1000 Mt CO2-eq (or 70% of estimated emissions) at costs below 100 US$ t(-1) CO2-eq year(-1). An estimated 20...

Municipal solid waste (MSW) management has an impact on climate generating greenhouse gases (GHG). To quantify GHG emission from MSW management activities (transportation, composting, recycling and landfill), this study was conducted in the Chittagong City Corporation (CCC). Data were collected about detail MSW management activities of the CCC through conducting a structured questionnaire survey on related personnel with MSW management. To collect data about recycling, another questionnaire survey was conducted on all junkshops near to both dumping sites (Anandabazar and Arefin Nogor) of the CCC. The study found that, composting and recycling of MSW have a positive contribution in reducing GHG emission. Transportation and land-filling of MSW have a contribution in GHG emission. The amount of GHG emission from the existing MSW management system of the CCC is 31,904.68 tons of CO2-eq per month. The life cycle assessment (LCA) study on composting shows that, the reduction of GHG emission is 3.66 tons of CO2-eq per ton of produced compost. The study finding is expected to contribute to the field of climate change mitigation in Bangladesh. The Chittagong Univ. J. Sci. 40(1) : 21-46, 2018

“…The amount of water injected and the size of the water droplets were adjusted so that the water droplets had time to evaporate before exiting the reactor. The reactor installation simulates the SO 2 removal process where limestone is injected into the furnace and the calcination product, CaO, is activated in the humidification reactor [CaO ϩ H 2 O 3 Ca(OH) 2 ] to enhance the sulfur capture according to the reaction SO 2 ϩ Ca(OH) 2 …”

“…In addition, decomposition of biodegradable wastes produces gaseous emissions of compounds to the atmosphere, such as CO 2 , CH 4 , and N 2 O, that are known to have an impact on global warming because of the greenhouse effect. 1,2 Within the European Union (EU), the Directive on the Landfill of Waste aims to minimize the amount of landfilled and, especially, biodegradable wastes by effective recycling, source separation, and reprocessing of wastes to refuse-derived fuels (RDFs) and, therefore, the mitigation of greenhouse gas emissions from landfills as well as other negative effects on the environment. 3 The global objectives of the Kyoto Protocol and the EU-wide efforts to reduce CO 2 emissions by promoting the use of CO 2 -neutral fuels, such as wood and other biomass, in electricity production 4 have increased the interest of energy producers in the use of power processes where biomass and other usually lowgrade or alternative fuels can be utilized.…”
