Life cycle greenhouse gas (GHG) emissions associated with two major recovery and extraction processes currently utilized in Alberta's oil sands, surface mining and in situ, are quantified. Process modules are developed and integrated into a life cycle model-GHOST (GreenHouse gas emissions of current Oil Sands Technologies) developed in prior work....
A life cycle-based model, GHOST (GreenHouse gas emissions of current Oil Sands Technologies), which quantifies emissions associated with production of diluted bitumen and synthetic crude oil (SCO) is developed. GHOST has the potential to analyze a large set of process configurations, is based on confidential oil sands project operating data, and re...
A typical office building in Thailand was analyzed using the life cycle energy analysis (LCEA) method to illustrate the argument. Results indicate that although life cycle energy (LCE) distribution is concentrated at the operating phase, the embodied energy of buildings is a non-negligible fraction of the LCE balance. Energy (electricity) used for...
Three input-output (IO) tables compiled between 1995 and 2000 were used to examine the significance of the construction sector and its relationships with other sectors of the Thai economy. The pull and push effect of the Thai construction sector to the national economy indicated that the former is much larger than the latter. Additionally, the rela...
This study examines construction waste generation and management in Thailand. It is estimated that between 2002 and 2005, an average of 1.1 million tons of construction waste was generated per year in Thailand. This constitutes about 7.7% of the total amount of waste disposed in both landfills and open dumpsites annually during the same period. Alt...
Background, aim, and scopeTo minimize the environmental impacts of construction and simultaneously move closer to sustainable development in the society,
the life cycle assessment of buildings is essential. This article provides an environmental life cycle assessment (LCA) of
a typical commercial office building in Thailand. Almost all commercial o...
The population of Lagos, the largest city in Nigeria, increased seven times from 1950 to 1980 with a current population of over 10 million inhabitants. The majority of the city's residents are poor. The residents make a heavy demand on resources and, at the same time, generate large quantities of solid waste. Approximately 4 million tonnes of munic...
The aim of this study is to estimate the amount of CO2— the most important greenhouse gas emission, for the Thailand economy. An input-output model based on energy and economic data is constructed in order to identify the sources of CO2 emissions and to discuss the share of sectors in total emission. Thus, the empirical application is for Thailand,...
While the Alberta oil sands represent a significant economic opportunity for Canada, their development also poses technical, environmental, and financial challenges. As such, considerable attention has been paid to developing, testing and eventually implementing new technologies to overcome some or all of the challenges. However, any decision to ad...

... In the case of Thailand, the EI and emission intensity for 2000 were analysed using the IO method for the 10 highest consumption industries and then compared with the same results from 1998 by Kofoworola and Gheewala (2008). Other studies have evaluated the nationwide effect of promoting NG vehicles (NGVs) and biofuel utilisation and compared them with the "business-as-usual" scenario results using an energy IO model (Tia et al., 2006;Suanmali and Limmeechokchai, 2015). ...

... The model and learning model is tested from literature review case studies [8,10,22]; the case studies include five [8], Japan [10], Thailand [22], Iraq [23], and the United Kingdom [24]. The inputs, outcome, and percent error are gathered in Table 1. ...
... Argonne National Laboratory of the United States has developed an evaluation model based on excel, and the Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) software has also been developed to assess the impact of alternative fuels and advanced vehicle technologies on carbon emissions in the entire fuel cycle process [17]. This is convenient and efficient because of its rich database. ...

... During this stage, the lifespan and the system boundaries are set, and the functional unit is defined. This research study set the life span of the building for 50 years which has been used by researchers for similar structures in past LCA studies [61][62][63]. To quantify the impacts annually throughout the complete life cycle and ensure comparability of different building systems, this research set a functional unit of one square feet (1 ft 2 ) of gross floor area (GFA) per year. ...
... These values are in good agreement with earlier studies. Charpentier et al. [44] and Bergerson et al. [45] reported life cycle GHG emissions in the range of 9-18 gCO 2 e/MJ. Because the pattern of energy consumption and GHG emissions in both cases is similar, we describe the performance of SAGD using the deep reservoir scenario. ...

... The phrase "construction and demolition (C&D) waste" refers to the solid waste generated during the new construction, refurbishment, and destruction of structures and buildings [1,2]. At most of the dump sites across the world, C&D trash often makes up 10-30% of the solid waste that is received [1]. ...
... Solid waste is regarded as a crucial part of the contemporary infrastructure in any society because of its substantial contribution to ensuring a safe environment and resolving public health issues connected to waste generation (Nabegu, 2016). Designing waste management systems should take into account and promote waste reduction, recycling, and recovery, as well as the use of appropriate waste treatment techniques more environmentally friendly technologies, and proper final disposal (Kofoworola, 2017). In most industrialized countries, Solid waste management has progressed and improved over time to reach its current level; along with these improvements, concomitant statutory requirements have also emerged (Williams, 2015). ...
