The aim of the present research work is to investigate the possibility of adding a mixture of non-granulated blast furnace slag (NGBFS) and steel slag, two wastes resulting from metallurgical industry which underwent calcinations previously, in the raw meal for the production of Portland eco-cement clinker. For this purpose, the NGBFS and steel slag from ArcelorMitall Steel Galati were analyzed for chemical, mineralogical and heavy metals contents. Two samples of raw mixes were prepared, one with typically raw mat...

In process of pig iron production besides main product, pig iron, also secondary products are formed, that have character of secondary raw materials and industrial wastes. The most abundant secondary product originating in the process of pig iron production, is blast furnace slag, its occurrence is about 300 to 500 kg for one ton of pig iron. Blast furnace slag originates from melting of gangue parts of metal bearing materials, slag forming additions and coke ash. Its chemical, mineralogical and physical – chemica...

Significant efforts should be devoted to reducing waste outputs from aquaculture operations in order to lower the environmental impacts of aquaculture in many parts of the world. Since most aquaculture wastes are ultimately from dietary origin, reduction of waste outputs should first be through improvements of diet formulation and feeding strategies. The first step in the production of feeds producing less solid waste is to eliminate poorly digestible ingredients (such as whole grain or grain byproducts used as bi...

In this study our object is management of obsolete pharmaceutical products, vaccines and other medical waste as: syringes, needles and vials after vaccination. A right way of waste management in generally is very important for one health environment and health life. It is responsibility of everyone to take care of environment. Our focus must be on reducing the hazardous nature and the volume of our waste, and separate more of their waste, and increasing our participation in work on waste management according EU le...
