AbstractEcological economics is an emerging field that offers significant room for creativity and innovation at the conceptual level on how to operationalize sustainability. It integrates economics with ecology and many elements from both the natural and social sciences to provide an integrated perspective on environment-economy interactions. A major policy dilemma that ecological economics addresses is how policy-makers can influence markets, so that they receive the 'right' signals from the na...

A thermally stratified reservoir water body is divided in vertical layers and horizontal zones according to water temperature and depth. The layers show different compositions of limiting nutrient because of the density of flow and due to inhabitants on the bottom of the reservoir exposed to sunlight. The bioassay for algal growth potential test (AGPT) is the most direct and effective way to determine a limitin...

Ground water is an important source of clean water supply throughout the world. A growing literature on the management of groundwater which takes into account the interaction of groundwater with surface water resupply sources (e.g., streams or lakes) is driven by concerns of intensified global fresh-water use coupled with increasing industrial and agricultural pollution levels. Our joint laboratory and numerical experiments simulate water withdrawals via two pumping wells from an unconfined aqui...

The goal of this paper is to contribute to environmental improvement. This goal has been achieved by the development of an algorithm that allows the optimization of fuel consumption and transport of combustion products. The paper considers the outlier – robust recursive algorithm. This algorithm is used for identification of multivariable ARMAX (Autoregressive Moving Average with Exogenous Variables) models. In this paper, we introduce pseudo-Huber loss function which is a continuous nonli...

A Computational Fluid Dynamics (ANSYS Fluent CFD) software was applied for the examination of a critical combined sewer section of Budapest (Hungary) sewer network. The critical part of the main branch is located at a combined sewer overflow (CSO) which is implying environmental risk for the receiving water body. The CFD simulations proved the anticipated disadvantageous hydrodynamic effects of the lateral inflow. A discrete phase model (DPM) was also applied to analyse the sediment transport...

In this study, we discuss a risk assessment method for spatial point source accumulation that is suitable for regional comprehensive prevention and control of environmental risks. The distribution types of spatial risk sources and other related data are collected and analyzed by adopting Fengtai District, Beijing as an example. On the basis of the spatial analysis algorithm, the environmental risk of region is comprehensively assessed from the perspective of risk-inducing factors, risk substa...

The films and the developing solutions used with radiological films contain a number of harmful substances that are very toxic to the environment, as well as to the living organisms, particularly aquatic organisms. Therefore, this type of toxic waste requires simple, but adequate collection and treatment measures, in order to be transformed into environmentally friendly products. This paper reviews the existent knowledge and the methods for the management of this special waste in dentistry-rela...

The paper highlights the problem of assessing the level of environmentally acceptable green transport in modern supply chains. Cargo owners put the elements of time and price of service into the forefront, where the degree of pollution (CO2, NOx, SO2, PMs) and the need for energy efficiency is too often ignored. Various studies highlight the lack of methodological approaches to the standardized evaluation of the environmental impacts of intermodal transport, thus the aim is to formulate a modul...

An experimental inquest was performed to quantify the turbulent flow characteristics near the eroded region of an artificial sidewall bank at three different flow depths, and a comparison study is made between before and after erosion for two Reynolds numbers. Instantaneous flow velocities were taken with an acoustic Doppler velocimeter (ADV) at near bank of the vertical side wall. The mean flows and other turbulence quantities such as Reynolds shear stress, turbulent intensities, and turbulent ...

Tourist cities are facing an ecological crisis due to population boom, pollution and environmental damage. To solve the crisis, this paper attempts to make an accurate evaluation of ecological carrying capacity of tourist cities, identify the factors affecting the ecosustainability of such cities, and prepare a feasible solution to these factors. Specifically, the tourism ecological footprint theory was introduced into the evaluation of sustainable tourism development in tourist areas based on S...

In this paper, we propose innovative solutions for reusing an inactive offshore gas platform and its associated infrastructures as a scientific research hub, where an integrated energy system and innovative environmental monitoring methods are envisaged. To this end, the Azalea A platform, located in the northern Adriatic Sea, is considered a good pilot site. This study analyzes the engineering solutions on Azalea A for the combined production of solar and wind energy coupled with hydrogen produ...

Space exploration requires reliable, rapid, significant and safe methods for preventing, monitoring and controlling biocontamination risk in water loops and humid areas in manned Space habitats. Water is one of the most important resources of our everyday life. Its microbiological control in houses, public water dispensers and special conditions (e.g.: epidemics, catastrophes, isolation) is crucial. The presented solution is automated, compact and portable, and above all “integrated&rdquo...

Biomethane is incentivized in Italy and in many other European countries as a substitute fuel for transport, in order to reduce fossil fuel and cut CO2 emissions. In Italy, Certificato di Immissione in Consumo (CIC) is actually sustaining biomethane production, charging petrochemical companies who need to cover their obligation quotes. Actually, biomethane production has to fulfil sustainability requirements in order to be entitled to get CIC. Sustainability principles are, among others, the typ...

Optimal evacuation routes are crucial to protect workers’ safety when accidental leakage of toxic gas occurs in chemical plants. However, the majority of route optimization focuses on the transport field and few on the evacuation routing optimization in chemical plants. This paper proposes a dynamic evacuation routing optimization method for chemical plants under toxic gas release scenarios. From the complete accident scenario set (CASS) built with wind fields and leakage sources, the leak...
