... Because it offers an effective means to alleviate current ecological problems and a way to coordinate sustainable economic and social development with protection of the environment, eco-compensation has become a subject of interest to scholars and governments all over the world. A great many studies have been carried out and eco-compensation schemes have been put into practice; there have been man ...

Abstract:
... Eco-industrial Parks (EIP) have become a central element in China’s industrial strategy to combine industrial development while minimizing environmental impacts and improving resource efficiency. National standard system has been developed as a main tool for assessing EIPs. This paper provides a review of the development of China's EIP standard system. The focus of the analysis is the new national ...
... Water inflow into deep excavations is a key parameter in the evaluation of environmental impact, and a simplified method is needed to calculate the inflow with adequate accuracy, especially for a deep excavation with a cutoff wall around it. This paper presents a model for calculating inflow based on the method of fragments, assuming two-dimensional sectional flow. The effects of cutoff wall thick ...

Abstract:
... Over the last five decades, the Athabasca River Basin in Alberta, Canada, has been subjected to a wide range of environmental stressors from diverse human developments. This has resulted in an escalation of government, academic, industry and community-based monitoring and research efforts. However, despite all the attention received, a comprehensive synthesis of what has been studied is lacking, i ...

Abstract:
... The increasing demand for clean energy with minimum environmental impact motivates development of geothermal energy. Simulating a geothermal reservoir is complex and time consuming, mainly because of the systems spatial and temporal non-isothermal nature and the enormous size of the domain/reservoir. Simulations become even more complex when representing Enhanced Geothermal Systems (EGS), where we ...

Abstract:
... Living organisms are constantly exposed to wide ranges of environmental cues. They react to these cues by undergoing a battery of phenotypic responses, such as by altering their physiological and behavioral traits, in order to adapt and survive in the changed environments. The adaptive response of a species induced by environmental cues is typically thought to be associated with its genetic divers ...

Abstract:
... Antimony (Sb) is a toxic metalloid, and its pollution has become a global environmental problem as a result of its extensive use and corresponding Sb-mining activities. The toxicity and mobility of Sb strongly depend on its chemical speciation. In this review, we summarize the current knowledge on the biogeochemical processes (including emission, distribution, speciation, redox, metabolism and tox ...

Abstract:
... On November 2015, one of Brazil's most important watersheds was impacted by the mine waste from Fundão dam collapse in Mariana. The mine waste traveled over 600 km along the Doce River before reaching the sea, causing severe devastation along its way. Here we assessed trace element concentrations and cytogenotoxic effects of the released mine waste. Water samples were collected along the Doce Rive ...

This work was aimed at conducting a multi-objective exergoeconomic and exergoenvironmental optimization of continuous synthesis of solketal through glycerol ketalization with acetone in the presence of ethanol as co-solvent and Purolite PD206 as catalyst. Exergoeconomic and exergoenvironmental performance parameters of the reactor were computed and discussed comprehensively after writing and solvi ...

Abstract:
... Sulfate ions (SO42−) are ubiquitous in aqueous environments and are generally considered to be inert due to their chemical stability. For the first time, we found that SO42− can be activated into SO42--type radicals (e.g., SO3-, SO5-, SO4-) in the presence of phenolic compounds under simulated or natural solar irradiation. In turn, the radicals promoted the transformation and mineralization of phe ...

Abstract:
... The current controversies on “sustainable growth”, “green growth” and “degrowth” cover many issues in the relations between human behavior, societal regulation and technology in face of the need to overcome the environmental crisis. The point of departure of this paper is the observation that the roles of technology and of technological progress in realizing an ecologically sound development often ...

Abstract:
... Adaptive reuse of buildings can be an attractive alternative to new construction in terms of sustainability and a circular economy. Achieving net benefits with adaptive reuse partly relies on efficiently planning building disassembly. The aim of this paper is to describe a new efficient single-target selective disassembly sequence planning method developed for adaptive reuse of buildings. Finding ...

Abstract:
... We investigated the role of urbanization in the conventional environmental Kuznets curve (EKC) of the globe. The overall population and rural population were also considered for control purposes. Based on our findings, we suggest that the conventional EKC of the globe is not an inverted U-shape but becomes downward sloping when urban development is added and inverted U-shapes when the overall popu ...

Abstract:
... The conceptual design phase is the first step in the design process of an engineering system. Most engineering systems, including cogeneration plants, may and likely will experience some malfunctions during its life cycle. The metrics typically considered in the conceptual design phase (and for analysis and optimization) of energy systems are cost, efficiency and environmental impacts. Quite rarel ...

Abstract:
... Human activity leads to environmental transformations, frequently on a large scale. There are places where anthropogenic consequences are unprecedented and disadvantageous to the extent that can be perceived in terms of an ecocatastrophe that goes beyond the local range. The article presents three anthropogenically degraded areas that pose danger for ecosystems in various parts of the world. ...

Abstract:
... The Horn of Africa region stands out amongst the planet's territories that are most volatile and vulnerable to armed violence. Conflicts have greatly affected the region over the past 50 years. The conflicts have disrupted the lives of people as well as the environment in ways that are not fully understood. Although armed conflict has generally had a negative impact on the environment, the environ ...
... Tourists must behave in a more environmentally friendly way to reduce the negative environmental impact of the global tourism industry. Only a few approaches have been developed to promote this. This may be because it is generally assumed that all kinds of environmentally sustainable behaviour have the same drivers. This study challenges this assumption. Results of this research indicate that spec ...

Abstract:
... Stream sites are abundantly available for small, ultra low head, hydropower applications with minimal environmental and ecological impacts compared to large-scale hydropower projects. However, little attention has been paid to these resources because of the relatively high weight and deployment costs of small turbines compared to the amount of power generated, which results from the use of stainle ...

Abstract:
... Life cycle impact assessment uses so-called characterization factors to address different types of environmental impact (e.g. climate change, particulate matter, land use…). For the topic of resource depletion, a series of proposals was based on heuristic and formal arguments, but without the use of expert-based models from relevant research areas. A recent study in using fish population models ha ...
