Waste recycling and the circular economy are among the most important issues in the European Union strategies. Because Romania has yet to meet many requirements of the European Commission?s policies, there have been opened several infringement proceedings against our country for pollution, wood management, and waste management. In May 2018, the European Commission sent a letter urging Romania to take major actions, such as: to close, seal, and ecologically restore 48 illegal landfills, and to comply with the judgm...

Hydrogeological hazards are very common when dealing with underground excavations, and they can bring about a damage both for the tunnel (e.g., tunnel inflow) and for the environment (e.g., water resource depletion). The paper proposes an example of the contribution of hydrogeology to risk management in tunnelling. In particular, the two following issues are addressed: how tunnel inflow can be assessed, and how its impact on water resources can be quantified. These issues are discussed based on the state of the ar...

Renewable resources? share in meeting the power balance in Romania grew constantly during the past decade. Therefore, the contribution of polluting energy sources (such as coal or oil) has progressively reduced. Moreover, to enable environmental impact mitigation for the still operating classical plants, proper desulphurization equipment were installed. It is remarked that the shares corresponding to hydro-energy and nuclear energy show an almost constant trend. Sensible investments were made in the energy sector,...

The structural design of concrete structures needs to result in qualities ensuring structural safety and serviceability, together with durability, robustness, sustainability and resilience. Due to this, the effects of mechanical load, environmental load and even social coherence need to be reflected and included in the formulation of limit states. This is a complex matter involving the time factor, service life, degradation effects, modelling, probability analyses, limit states, costs and other phenomena, and it i...

The paper deals with the monetization assessment of the environmental impacts of current systems of flat roofs. Monetization techniques are commonly used for evaluation of the negative environmental impact. Environmental impact can be defined as a change in the environment, whether favourable or unfavourable, which is wholly or partly due to human activity. Very often, environmental impacts are characterized by climate change such as global warming, acidification, eutrophication, ozone depletion, etc. With regard ...
