AbstractA comprehensive characterization of fly ash from Iasi, Romania has been carried out in order to set up the utilization potential of fly ash resulting in appreciable amounts from thermal power plants as a waste, which leads to soil and groundwater contamination, as well as atmospheric pollution. This fly ash can be classified on the base chemical and technological properties in F class. Having in mind the assignment of the processing conditions, the fly ash can be used as sorbent for poll...

Abstract One of most important concern for the food specialists is to solve the sociologically impact problems in parallel with the decrease of the pollution degree through the advanced capitalization of byproducts from the food industry. The paper debates the capitalization of beer industry byproducts known as malt radicles, and their use in the bakery industry, for the obtaining of dietetical bread. Along the malt radicles, KCl and Prima Pan improver were added to the bread’s dough, and...

Abstract At present, dangerous industrial wastes are a main source of environmental pollution because they are stored and deposited improperly. Besides, dangerous industrial wastes could also be a source of secondary raw materials which are not well capitalized. This fact causes substantial losses of secondary raw materials and energy and it is explained by the lack of certain technologies of treatment, capitalization and final removal that are technically and economically sustainable. To ide...

AbstractIncreasing the labor force employment and participation rates is sustained by capitalization of human opportunities existent inrural areas. This entails a flexible and inclusive labour market and a decreasing rate of exclusion for some rural groups.This paper highlights the need of facilitating the access to the labour market by achievement of professional skills needed in nonagriculturalsectors from rural areas for the vulnerable groups as well as the entrepreneurial groups. The analysi...

AbstractConsidering the decrease water resources in the past decade, research for rational solutions on water use has become a worldwideconcern. Agriculture is the largest consumer of water, and when the soil moisture level is not assured of precipitation, it issupplemented by irrigation. In the current context of climate change, and consequently the arid territories growth, the researchersare looking for solutions to rational water consumption, and equally to cover the deficit of water in agric...

This paper examined some physical and mechanical properties of wood from thin trees of sessile oak collected from thinning operations, in order to recommend this secondary wood resource for potential superior applications (as solid wood panels and furniture components). Swelling, shrinkage, modulus of rupture (MOR) and modulus of elasticity (MOE) and compression strength parallel to the grain were examined and compared with data from literature reported for mature trees. The variation of the abo...

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...
