AbstractDuring the transition to a market economy, many countries with a planned economy in Central and Eastern Europe face similar challenges when the established socio-economic systems and infrastructures deemed inefficient in a market economy. Also new issues are being raised by the trends of globalization and the vision of sustainable development. In the energy sector the challenges raised by the Kyoto Protocol and its implementation mechanisms are especially interesting, because they are in...

AbstractAcademics have had numerous responsibilities during the centuries. However, now with global climate changes and the attendant, looming crises, it is increasingly crucial that administrators, faculty members, graduate, undergraduate students, staff members and alumni work together with governmental, non-governmental and industrial members in envisioning societies that are truly sustainable. The visions must then be effectively and efficiently implemented in numerous locations throughout t...

Abstract To become "flexible" is the equivalent of becoming successfully for almost any firm - the activities based on old and traditional product "recipes" are, obviously, excluded. But, in the framework of a global economy crisis, the statistics seems to prove that flexibility is no longer enough in order to avoid troubles. At the same time, another statistics prove that almost 80% of the products are failing at their first release on market. The paper presents a genuine marketing aggregate...

When ignited, they can burnrapidly and with a considerable explosion force, when mixed with air in proper proportions. This is the reason why adequateprecautions have to be adopted, to ensure all equipment is appropriately protected so that the ignition likelihood of the explosiveatmosphere is diminished.Explosion preventing and protection precautions aim to stop explosion occurrence, by el...

Abstract An experimental study of mixing in autoclave vessel equipped with an anchor impeller was performed on the sludge proceeding from the treatment of mixed municipal and industrial wastewater. This unit operation is part of a process for the recovery of sludge. The mathematical modelling of the mixing was done having in view the scaling-up of this process. The mathematical model allows the calculation of the mixing power N as a function of the impeller diameter d, the vessel diameter D,...

The aim of this study was the diversification of fodder yeast assortments with viable economic effects while reducing the pollution to the environment by capitalisation of wastewaters with high monosaccharides content from pulp and paper industry. As inoculum, in the bioreactor, a mixture of two species of yeasts Candida utilis and Candida arboreea (1:1 ratio) was used at 38°C, pH 5.5 and an air flow of 0.02 L/h was insured. Wastewaters from technological process of pulping of softwood wi...

Urbanization and industrialization have led to the increase in impervious surfaces, the reduction of water seepage into soil and the increase of runoff discharges in urban areas. The overland flow may be carried over long distances along the streets and sidewalks depending on the land slope and morphology, while in lowland, water tends to accumulate in ponds. In this research, we aim to identify these ponds in the floodplain, slope and urbanized interfluves in Cluj-Napoca. The ponds outline t...

The management of urban solid waste is a growing priority both in large cities and in rural settings, and in developed and developing countries. Many factors can influence the type and amount of waste generated, including population density, level of industrialisation, quality of life of households, type of area (urban/rural) and local climate. In this paper, we introduce an index of solid waste recycling over a ten-year period and examine the influence of several such factors on this index. ...

With population growth and increasing industrialization, enormous amounts of agro-industrial wastes are being produced. Without proper use, these keep piling up leading to tremendous pressure on environmental safety. There is also considerable economic interest not only in the proper utilization of these wastes, but also in developing appropriate processes for this purpose. Sludge generated in pulp and paper mills is one of such solid wastes. Although several studies have investigated its reuse,...

The paper aims to present the sorption properties of two sorbent substrates (composts) prepared by aerobic fermentation from vegetables waste composted with beech sawdust (BR2) and beech ash (BC1) to be used for Cu2+ removal from wastewaters. The composts structures and surface properties were characterised in terms of active groups (FTIR), crystallinity (XRD), morphology (SEM), topography (AFM) and specific surface and pores analysis (BET), and the changes in properties after Cu2+ sorption were...

Chlorophenols, commonly found in industrial effluents, are considered as priority pollutants because they may cause severe environmental impacts and human health related problems. Nanofiltration (NF) represents an important option for the removal of chlorophenols present in aqueous effluents. This study presents some results on the performance of nanofiltration for the removal of 4-chlorophenol and 2,4-dichlorophenol from synthetic wastewaters considering the selection of adequate operating and ...

In the current context of industrialization, chemical and radioactive pollution is a concern for environmental protection and interference with human health. Care for environmental protection also includes vegetation that grows spontaneously in potentially contaminated places, thus avoiding illness among the population if consumed. The study area is located at 4.5km SSE from downtown Bacău City, Romania and is the result of the manufacture of H3PO4 through the wet method. In this study, t...

The objective of this study was to develop a naturally dyeing process of 70% wool /30% Angora mohair blended yarns by using bio-mordants as an environmentally friendly alternative for the conventional metallic salts. Bio-mordanting operation was achieved by using of condensed tannin extract from quebracho bark trees. Conventional mordanting has been performed using the conventional mordants like copper sulphate and tin chloride. Another specific objective of this study was to investigate the pos...

Acetone-Butanol-Ethanol (ABE) industrial production by fermentation is strongly affected by the low concentration of solvent (<25 g/L) that affects the cost of the recovery process. To decrease the overall cost of the butanol production, alternative routes for the recovery have proposed in literature. This paper presents a techno-economic analysis of an innovative butanol recovery process from ABE fermentation broth based on gas stripping technique. The comparison with a recovery process bas...

Deforestation is a vital problem at global level, being one of the main causes of climate change. Volume of wood used in construction, furniture and pulp and paper industries increases year by year. Stopping the decrease of forests surface is of imperative importance from the point of view of sustainability. Pulp and paper industry faces with severe lack of pulpwood and for this reason other raw materials are taken into consideration. Chemical pulp can be partially replaced with recovered paper ...

Analysis of main environmental components must be appropriate and useful for establishing decision-making elements regarding environment quality, the need for intervention and remediation in major cases, or improvements and development forecasting for local specific situations or subsequent climatic behaviour and composition transformation processes. In this respect, the usefulness of the information gathered from environmental analysis largely depends on how monitoring actions and environmental...

In the economic activities related to combustible substances, it may occur possible emissions and explosive atmospheres. Some typical examples include industrial activities in general, firedamp mines and power generation in particular. The aim of this paper is to accentuate hidden aspects regarding ignition sensitivity of moisturized air methane mixtures. Therefore, the first objective of the paper is to emphasize the air humidity as an extra factor needed to be considered in relation to igniti...

Discomfort caused by noise is ever-present, having numerous physiological, psychological and social implications. One of the most important discomfort factors for personnel working in the processes of surface coal extraction is represented by noise. This paper examines how noise generated by the process of lignite extraction influences the working capacity of employees. The covering effect of voice or different sound and verbal signals, during work, leads to tiring efforts of attention, thus de...
