Pekanbaru City is the capital of Riau Province which center government and economy with a large population growth rate. Urban activities will produce solid waste liquid which, if not managed, cause adverse environmental impacts, one effect Greenhouse Gases (GHG). The purpose this study was to determine value emissions from in City. calculation GHG two sectors based on IPCC 2006 refinement 2019....

The conventional landfilling does not promote sustainable waste management due to uncontrolled emissions which potentially degrade the environment. In this regard, pre-treatment of municipal solid waste prior to landfilling significantly enhance waste stabilization and provides various advantages. So in this regard pre-treatment methods of municipal solid waste were investigated. The major obje...

Background and Objective:  one of the major challenges in urban management in human societies is related to the collection, recycling and disposal of solid waste and sewage. Poor waste management causes pollution of water, soil and air. It will have a major impact on public health. The aim of present study was to investigate the current status and select the best options of management of munici...

Selected heavy metals (HMs) including Cd, Cr, Cu, Ni, Pb and Zn initially released from a full-scale bioreactor landfill were monitored over the first 20 months of operation. At the initial landfill stage, the leachate exhibited high HMs release, high organic matter content (27000-43000gl(-1) of TOC) and low pH (5-6). By the fifth month of landfilling, the methanogenic stage had been establishe...

The Gaza Strip faces a chronic solid waste (SW) management and electricity shortage problem as a result of fifty years of political instability in the area coupled with a high population growth rate, an unhealthy economic condition, and limited land and energy resources. The option to develop a waste to energy (WTE) facility to manage SW and to alleviate the electricity shortage has not been pr...

We model a municipal solid waste (MSW)-to-ethanol facility that employs dilute acid hydrolysis and gravity pressure vessel technology and estimate life cycle energy use and air emissions. We compare our results, assuming the ethanol is utilized as E85 (blended with 15% gasoline) in a light-duty vehicle, with extant life cycle assessments of gasoline, corn-ethanol, and energy crop-cellulosic-eth...

Post-consumer waste is a small contributor to global greenhouse gas (GHG) emissions (<5%) with total emissions of approximately 1300 MtCO 2-eq in 2005. The largest source is landfill methane (CH 4), followed by wastewater CH 4 and nitrous oxide (N 2 O); in addition, minor emissions of carbon dioxide (CO 2) result from incineration of waste containing fossil carbon (C) (plastics; synthetic texti...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Due to initiatives such as the clean development mechanism (CDM), reducing greenhouse gas emissions for a developing country can offer an important route to attracting investment in a variety of qualifying project areas, including waste management. To date CDM projects have been largely confined to schemes that control emission from landfill, but projects that avoid landfilling are beginning to...
