Reduce Emissions

Emission of methane from landfills due to anaerobic decomposition of organic material is oneof the most important environmental concerns with regards to solid waste management. Thisis due to the amount of methane released from landfills globally and the relatively high globalwarming potential of methane. An approach to reduce emissions is to improve conditions forbiological oxidation of methane in the top cover using engineered biocovers.A demonstration project was initiated at the Technical University of Denmark under the EULife Environment program, where this technology is applied in full scale at section I on Fakselandfill in Denmark. Construction of the full scale biocover at the test site was completed attime of writing.The main project objective was to document the construction and efficiency of the system.The project actions consist of a logical order of tasks performed in able to meet the objectivesof the project. At first the landfill was characterized. Expected landfill gas production wasestimated based upon the collected data using models. Then, a baseline study was performed,consisting of an evaluation of the spatial variability in methane emission at the site. The totalmethane emission from the landfill was measured by use of a tracer technique.Mixtures of locally available soils and organic waste residuals were tested by laboratory batchand column experiments. A cover improvement plan included details on material additions toselected areas of the landfill, maintenance plans of the total landfill cover. A plan formonitoring performance was setup. The emissions after the cover improvement will becompared to the emissions obtained during the baseline study. Scenarios for other landfillswill be calculated based on the experiences obtained from the studied landfill.

System Characteristics

HDR partnered with the Lancaster County Solid Waste Management Authority (Authority) to use the Carbon Assessment Planning Tool (CAPT) to evaluate GHG emissions in their solid waste system. The Authority owns three primary facilities, which comprise the Authority’s solid waste processing and disposal system (the System). The primary facilities in the System are the Transfer Station (TS), the Frey Farm Landfill (FFLF) and the Lancaster County Resource Recovery Facility (RRF). The Authority has recently added wind turbines to its energy portfolio and is considering other changes within its system. The model will be used to evaluate the net effect of the changing system characteristics on the Green House Gas emissions from the system. Reduction in the waste landfilled, changes in Landfill Gas production and increases in energy production will all be evaluated. The paper will review the model assumptions and parameters and will discuss system characteristics. The paper will also discuss a methodology for monetization of additional “green benefits” associated with the GHG emissions reductions through the sale of emission offsets.

Makkah City

In many countries, open dumping is considered the simplest, cheapest, and most cost-effective way of managing solid wastes. Thus, in underdeveloped economies, Municipal Solid Wastes (MSW) are openly dumped. Improper waste disposal causes air, water, and soil pollution, impairing soil permeability and blockage of the drainage system. Solid Waste Management (SWM) can be enhanced by operating a well-engineered site with the capacity to reduce, reuse, and recover MSW. Makkah city is one of the holiest cities in the world. It harbors a dozen of holy places. Millions of people across the globe visit the place every year to perform Hajj, Umrah, and tourism. In the present study, MSW characterization and energy recovery from MSW of Makkah was determined. The average composition of solid waste in Makkah city is organic matter (48%), plastics (25%), paper and cardboard (20%), metals (4%), glass (2%), textiles (1%), and wood (1%). In order to evaluate energy recovery potential from solid waste in Kakia open dumpsite landfill, the Gas Generation Model (LandGEM) was used. According to LandGEM results, landfill gas (methane and carbon dioxide) generation potential and capacity were determined. Kakia open dump has a methane potential of 83.52 m3 per ton of waste.

Based on a case study comparing different approaches for management of organic waste generated in the city of Rio de Janeiro, Brazil, this study proposes the combination of consequential lifecycle assessment (CLCA) and multicriteria decision analysis (MCDA). Compared approaches were landfilling with energy recovery from landfill gas, source segregation of organics for anaerobic digestion and use of digestate as fertilizer, and finally, post-sorting of organics and landfilling of residual bio-solids. Seven different impact categories were assessed in the CLCA. In addition, recovery of electricity and macro nutrients were included as additional impact categories. The use of VIP analysis facilitates the interpretation of results aggregating them under different conditions. Furthermore, approaches for ranking of considered impact categories could be carried out both for a local or a global perspective. This, and the possibility of easily including additional context derived evaluation parameters, clearly highlights the combination of CLCA and VIP analysis for decision support.

Summary Marine-gas-hydrate-drilling exploration at the Eastern Nankai Trough of Japan revealed the variable distribution of hydrate accumulations, which are composed of alternating beds of sand, silt, and clay in sediments, with vertically varying porosity, permeability, and hydrate saturation. The main purposes of this work are to evaluate gas productivity and identify the multiphase-flow behavior from the sedimentary-complex hydrate reservoir by depressurization through a conventional vertical well. We first established a history-matching model by incorporating the available geological data at the offshore-production test site in the Eastern Nankai Trough. The reservoir model was validated by matching the fluid-flow rates at a production well and temperature changes at a monitoring well during a field test. The modeling results indicate that the hydrate-dissociation zone is strongly affected by the reservoir heterogeneity and shows a unique dissociation front. The gas-production rate is expected to increase with time and reach the considerable value of 3.6 × 104 std m3/d as a result of the significant expansion of the dissociation zone. The numerical model, using a simplified description of porosity, permeability, and hydrate saturation, leads to significant underestimation of gas productivity from the sedimentary-complex hydrate reservoir. The results also suggest that the interbedded-hydrate-occurrence systems might be a better candidate for methane (CH4) gas extraction than the massive hydrate reservoirs.
