“…Different OS types from various worldwide regions give different product yields, as the organic matter and lower heating value (LHV) in OS can vary from 5 to 80% [40] and from 5 to 20 MJ/kg, respectively. OS retorting processes have been studied to improve the quality and increase the yield of usable products [4,19,41]. However, there are still different issues to be resolved from the individual retorting of OS.…”

“…The current accelerating increase in energy consumption, shortage of natural resources, environmental pollution and depletion of conventional fossil fuels around the world have urged the research and implementation of clean, alternative and renewable sources for energy generation and production of fuels [1,2]. The use of conventional fossil fuels as a source of energy and petrochemical products has increased the emissions of CO 2 significantly and altered the carbon balance on Earth [3,4]. A promising economically feasible and cleaner alternative to the production of improved biofuels and chemicals is the co-pyrolysis of carbon-neutral fuels, such as biomass (BM), and alternative fuels, such as oil shale (OS) [5][6][7].…”

The use of biomass (BM) and oil shale (OS) blends for the production of cleaner and improved fuels and chemicals through co-pyrolysis has recently attracted attention. The potential benefits, synergetic effects, interactions and promotion and inhibition effects of co-pyrolysis of BM and OS are reviewed and analyzed in this article based on an overview of various recent studies of co-pyrolysis, including the experimental and operational parameters and the yield and composition of the products. The effects of co-pyrolysis on different feedstock blends are discussed to guide future research on BM and OS copyrolysis. The effects of different pyrolysis parameters that can improve the pyrolysis process and quality of products are also reviewed. These parameters include CO 2 and steam atmospheres, heating rate, reaction temperature and particle size. Overall, in most cases reviewed, co-pyrolysis can enhance the yields of bio-oils, producer gas and chars as well as improve their properties while reducing the environmental effects of fossil fuels.

“…Therefore, its efficiency remains low and it is harmful to the environment. [148,149] On the other hand, the Kiviter retorting technology, [150] which uses lump shale heating using special types of furnaces, can go up to a 125 mm particles size, has a modest arrangement, fast conservation, and a large throughput of $1000 to 3000 t/d. This process, however, suffers from losses in raw material, that is, the oil shale, has high operational expenses, and produces gas with low calorific value and la significant amount of carbon coal solid waste, that is, a value of $480 kg/t.…”

Depleted fossil fuel resources have led to an investigation of other promising alternatives such as renewable and unconventional energy sources. Shale formations have limited permeability. Therefore, several extraction techniques have been applied to improve residual oil recovery and production. In this work, the techniques applied above ground to extract the organic fractions from oil/gas shale are discussed. Studies related to compositional fractionation, ultrasonic-assisted, microwave-assisted, supercritical fluids, and surface retorting techniques have been conducted systematically in approximately 150 scholarly articles over the past 10 years. The impacts of each technique as well as the drawbacks and challenges are highlighted in this paper. The fractionation techniques are sufficient in general; however, they are time consuming as they include several stages and use a considerable amount of solvents. Ultrasonic and microwave techniques are highly reliant on formation transparency linked to the organic fraction heterogeneous distribution. The surface retorting method, which is highly efficient with up to 90% recovery, for example, the Galoter and Paraho methods, is still dependent on shale particulate size, generates a massive amount of spent shale as waste, and is prominently emissive. Therefore, assessments that can be used to overcome existing drawbacks are considered. This can provide practical insight about these techniques to overcome limitations and concerns in terms of efficiency, cost, environmental issues, and reliability features. The work highlights the dominant extraction techniques for further development.

“…There is a need to improve on the conventional LCA method as well as on its use for assessing the LCA of buildings. In life cycle analysis, exergy enables the quantification of the cumulative consumption of resources [6], as well as serving as an indicator of efficient energy and resource use [7,8]. Exergy provides a potential indicator of environmental impact [9] and, thus, can be applied to LCA.…”

The relevance of exergy to the life cycle assessment (LCA) of buildings has been studied regarding its potential to solve certain challenges in LCA, such as the characterization and valuation, accuracy of resource use, and interpretation and comparison of results. However, this potential has not been properly investigated using case studies. This study develops an exergy-based LCA method and applies it to three case-study buildings to explore its benefits. The results provide evidence that the theoretical benefits of exergy-based LCA as against a conventional LCA can be achieved. These include characterization and valuation benefits, accuracy, and enabling the comparison of environmental impacts. With the results of the exergy-based LCA method in standard metrics, there is now a mechanism for the competitive benchmarking of building sustainability assessments. It is concluded that the exergy-based life cycle assessment method has the potential to solve the characterization and valuation problems in the conventional life-cycle assessment of buildings, with local and global significance.
