The technology of cold ironing (or shore-to-ship power) can meaningfully reduce greenhouse gases and air pollutant emissions from ships at the berth by powering vessels electrical shore grid. While constitutes an effective affordable solution in northern Europe America, economic, legal, environmental factors still render this less attractive southern Europe. This paper aims to unpack analyze regulatory, that foster as a standard installation Mediterranean Sea. Based on model design for port...

Recovery of fine non‐ferrous metals from waste streams is a notoriously difficult problem in eddy current separation technology. Existing processes either have low capacity or an incomplete recovery for particle sizes below 5 mm. In new process, the particles are fed slightly wet to make them stick surface conveyor belt. The action magnet rotor makes tumble, so that they break loose belt and end up front rotor. process combines relatively high with almost complete recovery, even heavy poorly...

Steel production wastes (steel slags) are used more often in asphalt concrete pavements as a valuable replacement for natural aggregates, which becoming increasingly rare. In this paper authors investigate the polishing characteristics of and particular steel slags, bituminous road surfacing, major factor determining resistance to skidding. The main purpose study is identification suitable degradation model, based on friction indicators, laboratory, well comparison in-situ pavement skid with...

The paper illustrates the phases and results of an evaluation model applied to abandoned industrial areas affected by critical environmental pollution. main aim is provide economic impacts pollution on market value areas, in anticipation their future requalification refunctionalization. Firstly, two mass appraisal models are applied: a regressive order isolate effects real estate valorization generated interventions steel mill Bagnoli Naples (Italy); autoregressive relation chronology...

To reduce thermal susceptibility and improve rutting fatigue cracking resistance, increasingly more non-conventional additives materials have been used in road pavement asphalt mixes recent years. Non-conventional mainly include recycled materials, which production costs lead to environmental benefits related their reuse. The aim of this research was evaluate the influence tyre rubber concrete for pavements built with aggregates consisting steel slag relation possible improvements structural...

Expanded glass with thermal and acoustic insulation properties are obtained from a foaming blend composed of 97% waste 3% expanding agent. This latter is carbon manganese oxides, recovered exhausted alkaline batteries. The samples produced after heating the mixture in ventilated furnace at temperatures between 850 950 °C, for times 15 60 min. Mechanical, characterized as function process parameters. foam have densities range 290–350 kg/m3, porosity 86–90%, conductivity values 107–120 mW m−1...

This contribution aims to provide an in-depth outlook of the phase-out coal-fired energy generation in Italy. In particular, this article analyzes state-of-the-art with regard both current role coal and performance main legal regulatory tools as implemented Italy thus far ensure closure all power plants by 2025 announced Italian National Climate Energy Plan. Based on existing data scenarios electricity production demand trends, unfolds marginal played mix. addition, paper highlight...

Coal water fuels (CWF) are aqueous suspensions of fine coal and used as fluid fuel. Their solid content must be high possible. Unfortunately, when the particles coarse, there is a fast settling inside pipelines tanks; on other hand, with CWF viscosity increases it difficult to pump slurry through pipelines. A solution mixture coarse bimodal particle size distribution appropriate surfactant improve surface wettability. The fine/coarse ratio, total amount solid, additives, presence entrapped...

Sustainability and integration are becoming keywords in many European Union policies, including ones that directly or indirectly related to mineral resources waste management.Moreover, life cycle thinking (LCT) is core of these policies.The Commission has issued the Communications "A resource efficient Europe" "Roadmap a Resource Efficient Europe", stated goal which reconsider whole use so as make "circular economy", one based on recycling resource.Construction Demolition Waste (C&DW)...

The tuberculin skin test (TST) can be used to identify HIV-infected people who would benefit the most from long-term isoniazid preventive therapy (IPT). However, in resource-constrained settings, implementation of TST challenging. objectives this study were assess feasibility implementing for IPT initiation and estimate proportion TST-positive incidence among HIV-positive patients 2 high tuberculosis HIV burden settings.Two prospective observational cohort studies conducted under...

Empirical treatment of tuberculosis (TB) may be necessary in patients with negative or no Xpert MTB/RIF results. In a context access to Xpert, we assessed mortality the 6 months after initial TB consultation among HIV-positive and HIV-negative who received empirical based on bacteriological confirmation compared it those did not receive treatment. This prospective cohort study included consecutively adult signs symptoms attending an outpatient clinic Western Kenya. At first consultation,...

The investigation discussed in this article concerned the removal of wires and cables fraction contained automotive shredder residue (ASR) through a newly invented device, called ‘nail roll’. Series tests were carried out with three ASR samples different origin influence setting parameters machine was analyzed. Other separation techniques their combination nail roll also investigated, pursuing objective increasing profit entire processing chain. results indicate that recovery index...

Abstract Static and dynamic stability in dense medium separation processes are defined, a model for DMS systems provides the density differential (a measure of stability) as function static parameters related to geometry separatory vessels operating conditions. A pilot test rig was installed to: (a) study behaviour conical cylindrical separators particularly concerning sink float densities under different conditions; (b) check correlation between stability.
