Purpose – The purpose of this paper is to define suitable tracers that are particularly significant in assessing the impact on the surrounding environment caused by a steel making plant. Design/methodology/approach – The authors focussed on the detection and quantification of inorganic pollutants such as heavy metals in the soil and in the air in the surrounding area of the steel making plant. The presented data, concerning a plant in the North part of Italy, come from an approach that took into account the advantages of different devices and sampling criteria: apart from conventional devices, two kinds of deposimeters have been used (for characterizing either total or wet/dry depositions). Their locations have been chosen taking into account the distance from the plant. Findings – The paper demonstrates that the presence of diffused emissions plays an important (negative) role still today; thus a modern plant should reduce this kind of emission in order to be accepted from the population living in the surroundings. In the analyzed case study, the benefits of adopting the best available technologies can be seen from the temporal variability of the incidence of the plant. Originality/value – The value of the paper is in the support that it can give to decision makers that must manage a steel making plant in an area.

Purpose – The purpose of this paper is to contribute to the qualitative and quantitative knowledge on ultrafine particles in air near a steel making plant located in an Italian site. Design/methodology/approach – A combination of experimental methodologies was used for the online and offline monitoring and chemical characterization of particulate matter (PM) in the air near the plant. Two unfiltered twin-sampling systems were adopted, working when the plant was on/off. All condensed air samples were submitted to Ion Chromatography analysis. The same samples were submitted to acid digestion before Graphite Furnace Atomic Absorption Spectroscopy Analysis. Continuous daily PM10 samples were collected to characterize ambient air. PM10 samples were also analysed to estimate metals content. The PM size distribution was achieved by continuous online monitoring. The adopted ultrafine particulate monitor classifies particles in the range 20-200 nm. The overall size distribution was inferred from an Optical Particulate Counter able to classify particles in the range 0.3-10 µm. Findings – The obtained results show that no causal relationship can be found between the measurements of anions and metal in the air near the plant under investigation and the presence of the steel making plant. The trend in emissions of micro-particles was found quite characteristic of similar semi-urban areas. Originality/value – The paper demonstrates that a steel making plant adopting best available techniques could have a local impact compatible with the surrounding environment.

Purpose – In the EU, over the past three decades, poultry production has been growing around the 5 percent per year. This increase determined a higher volume of livestock and poultry farming waste, which represents a potential renewable fuel suitable for waste to energy conversion. One way is through biological process such as the dry anaerobic digestion (AD). Tests normally applied for the measurement of the anaerobic biogas potential (ABP) are reliable, but not feasible as a routine analysis. This kind of test is expensive and time consuming (21-100 days). The purpose of this paper is to propose a rapid method for assessing the potential of biogas in anaerobic poultry manure, with the goal of helping the choices of operators of AD. Design/methodology/approach – The Dynamic Respiration Index was calculated as “key parameter” in order to estimate the ABP, which provides important information about the biogas generation for the poultry manure. Furthermore, two dynamic respirometric approaches were considered developed in two Italian universities. The main difference between them is the control of temperature. Findings – Calculate ABP through IRD is a useful method to determine the value of the potential production of biogas of different biomasses in a short time and assess which one is more productive. Originality/value – The methodology presented in this study is fast (one-five days) and alternative method to determinate the ABP, above all for the operators of AD plant.

Since 1984, the Galapagos Islands have been included in the program UNESCO—MAB (Man and Biosphere Programme) due to the increasing need to safeguard their outstanding natural ecosystems and promote economic progress based on principles of sustainable development and environmentally friendly technologies. The Ecuadorian government, also by special laws, has legislated in favor of the environmental protection of the archipelago, with the intention to control the flow of migrants from the continent to the islands. Today, with the further problems created by the massive influx of tourists, is it necessary to establish planned areas of urban expansion that are already equipped with a suitable system of collection and treatment of wastewater. This paper focuses on the city of Puerto Ayora, the main town of the island of Santa Cruz, where increasing human pressure has led to, among various other consequences, an increase in water demand, which has highlighted the inadequacy of the current wastewater treatment system, based primarily on single-family septic tanks without additional depuration. Among the various actions proposed to solve the increasing health and environmental hazards, caused by the partially treated wastewater, a centralized sewer system for the drainage and the depuration of the wastewater produced by the users connected to the network has been proposed in order to serve the community of Puerto Ayora. This project is currently experiencing a slow implementation process due to technical difficulties. Our intention is to propose a different wastewater management system, which is modular, easily replicable and which requires low maintenance. A flexible and easily manageable system, such as that proposed, could be implemented in other contexts such as, for example, in developing countries. In this specific case, the main purpose of this study is to investigate how to ensure a healthy environment for tourists and residents, without neglecting our duty to respect the ecosystems of this extraordinary island, by defining a model of wastewater management which should be economically and technologically sustainable in this particular context. In fact, the soil, formed by lava rock does not allow for very deep excavations and being so far away from the mainland means that technologies that are easily maintainable on site must be deployed. The study was carried out according to the Millennium Development Goals, Ecuadorian legislation, the suggestions of the Pan American Health Organization, relevant scientific literature and some data collected from site surveys.
