The Kyoto target for Romania was to reduce its carbon dioxide emissions by 8 % from the 1989 levels. The 1989 emissions were around 260 million tones. In 2000 the net CO2 emission - some 125 million tones - were 54% of the net CO2 emission in the reference year -1989, leaving some 115 million tones as a reserve or as a tradable resource to other countries that can not met their Kyoto targets.

Abstract:An efficient conversion of kinetic energy of river waters into mechanical or electrical energy without building barrages isprovided by micro-hydropower stations. Increased efficiency is achieved by an optimum position of the blades withhydrodynamic profile. The formulation used to compute the hydrodynamic forces is an inviscid - boundary layer model. Microhydropowerstation provides kinetic energy conversion of river water into mechanical or electrical energy without buildingbarrages. In...

Methane (CH4) is one of the greenhouse gases, with an ability to trap heat in Earth's atmosphere 21 times greater than carbon dioxide (CO2) per unit mass and in the same period of time. Because the lifetime of methane in the atmosphere is relatively short, it could be kept under control. Wastewater treatment plants (WWTPs) are anthropogenic sources of CH4 emissions.

Abstract The European Commission has introduced a whole range of policies and initiatives to promote the product eco-innovation and the environmental impacts reductions. One of the key topic for the reduction of the environmental impacts is the waste recycling and reuse (turning waste into useful resources). A teamwork of Politecnico di Milano has developed a research work, still ongoing and continuously updated, called “The usefulness of the useless. Cross-sectorial evaluation of wast...

Abstract The recycling and later use of construction and demolition waste (C&D waste) as construction materials present a strategic inconvenience for many stakeholders involved in the sustainable construction. In some countries, the recycling percentage of C&D waste is around 80% of the C&D generated. However, in other countries this percentage is much lower. This complexity requires a better understanding of the recycling dynamic. In the specific case of Spain, the National Inte...

Abstract It has been shown that the scale of damage in buildings with steel reinforcement, due to direct lightning strikes, is insignificantly small compared to lightning effects on buildings with no such steel reinforcement. Observed small-scale damages are also confined to points of strike; hence the only risk for occupants and properties is injury or damage caused by falling materials. A large number of such cases have been observed in Sri Lanka and Malaysia. All damaged structures, obser...

Environmental issues have received ascending attention in recent years due to the increase of their negative effects. Greenhouse gas emission levels have experienced an exponential increase in the last decades mainly on account of the development of the building sector. Life cycle assessment (LCA) of buildings is a proper tool to analyse the full environmental impact during their designed lifespan. Inventory databases have a shortage of local parameters in some countries and need to be developed...

This study applied a novel receptor design to the development of an indoor air quality diagnosis (IAQD) system. Indoor air pollutants were converted into simple air quality and health damage indices to evaluate the health risks associated with renovated and unrenovated offices. The outcomes of the IAQD methodology presented R2 values of 0.705 and 0.700 for renovated and unrenovated offices, respectively. These values indicate moderate level of prediction accuracy. IAQD results related to typical...

This paper focus on how prefabricated building systems can allow the implementation of deconstruction strategies. Prefabricated mechanically fixed components, in comparison with conventional concrete and brick in situ construction, can be more easily separated during demolition, allowing its reuse, and even if this is not possible, at least allowing the recycling or the energetic recovery. It is very important that construction practitioners understand the benefits of the prefabrication. As a wa...

Molybdate anions are used in a lot of fields and represent an essential trace element for plant and animal life; however, excessive amounts can cause adverse effect on various organism and environment. Therefore, in the present paper the adsorption performance of MgnFe- layered double hydroxides in the removal process of molybdate from aqueous solutions was studied. The layered double hydroxide (LDH) was synthesized by co-precipitation at low oversaturation method. Different ratio between Mg and...

The recovery of nutrients from sewage sludge ash, especial phosphorus, is one of the most important alternative in sewage sludge management. Phosphorus is an essential element for all living organisms and very important for agriculture and industry, as well as. Because the phosphorus is a non-regenerative resource, its recovery plays an important role for society. Phosphorus capitalization as struvite (NH4MgPO4.6H2O) from sewage sludge has attracted considerable attention due to its potential to...

The valorization of a metallurgical waste (i.e., an iron-rich slag) as raw material for the fabrication of high hardness glass-ceramics using differential thermal analysis, X-ray diffraction, X-ray fluorescence and scanning electron microscopy was investigated. The melting of the slag was aided by the addition of waste glass cullet (WGC) and the vitrification field of this system was investigated. The non-isothermal crystallization kinetics of the parent glass with the highest slag content was s...

This study aims to evaluate the properties of different wastes obtained from four red ceramic brick industries in the northern region of Santa Catarina, Brazil. The characterization of the clay brick waste (CBW) was performed using the XRD techniques, XRF, FTIR, DTA and SEM. Techniques to determine the pozzolanic activity, particle size, B.E.T. surface area and specific mass were used. The consumption of calcium hydroxide (CH) in the cementitious pastes with the CBWs was also measured. An app...

Since the era of the Industrial Revolution, energy consumption has considerably increased. As a consequence, a significant rise in greenhouse gas emissions has become a serious threat to environmental sustainability through climatic changes, global warming, natural disasters and pollution. In this context, increasing energy efficiency as well as the use of renewable energy can serve as important instruments for reduction of greenhouse gas emissions. The related literature has thus far generally ...
