MANAGEMENT OF WASTES FROM ENERGY INDUSTRY IN THE FRAME OF CIRCULAR ECONOMY ON THE EXAMPLE OF MICROSPHERES (Papers SGEM2018)

A. Wajda
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT Microspheres, in other words aluminosilicate grains, are spherical particles of a small size classified as volatile ash fraction, so-called by-products of combustion, produced in the energy sector. In their construction, two phases can be distinguished - gas and solid. They are (...)


POLYMER COMPOSITIONS FROM LEATHER FIBERS (LEATHER SHAVINGS) FOR MORTAR IN CONSTRUCTIONS (Papers SGEM2018)

G. Zainescu, V. Deselnicu, R. Constantinescu
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT In tanneries, only approx. one-third of the total mass of raw hides and skins is converted to finished leather, while two-thirds become either dissolved or solid waste. As part of the natural materials category, usually considered waste, leather fibers introduced into cement mortar (...)

ABSTRACT The paper aim was to analyze the awareness of eco-labelling on the market, the need for information on the subject and also the type of date which may be considered to be included in the contented. In order to analyze the promotion degree of sustainable development through (...)


PYROLYSIS OF POLYETHYLENE IN THE LABORATORY CONDITIONS (Papers SGEM2018)

M. Ticha, V. Dirner, R. Kucerova, K. Ossova, M. Szturcova
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT One of the possible innovative ways how to process and utilize waste is its pyrolysis in the pyrolysis unit Pyromatic 250. The tests were conducted by Ostravská LTS, a.s. in laboratory conditions in the ENET Center of VŠB-TU Ostrava. The input material was provided by MEVAPACK, s.r.o. (...)


RECYCLING OF NATURAL STONE WASTES OF WORKSHOPS IN KAHRAMANMARAŞ/TURKEY AS MINERAL PLASTER (Papers SGEM2018)

T. Rizaoglu, C. Coskun, D. Palka
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT Widespread use of natural stones has been a habit that has been going on for centuries. In addition to this widespread use, this material causes a significant amount of waste materials to be exposed during the processing of these materials. This is an economic problem in terms of both (...)


REUSE OF CERAMICS FOR HEAVY METALS REMOVAL FROM WASTEWATERS: SORPTION AND STABILIZATION (Papers SGEM2018)

M. Keppert, B. Dousova
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT Heavy metals ions can be removed from industrial wastewaters by numerous methods, such are precipitation, electrolysis, electrodyalisis etc. Sorption, i.e. adherence of a dissolved specie on solid sorbent, may be a cost-effective alternative to these conventional methods, in case a (...)


SUSTAINABLE RECOVERY OF PHOSPHORUS COMPOUNDS FROM SEWAGE SLUDGE IN THE CIRCULAR ECONOMY APPROACH (Papers SGEM2018)

A. Wajda, T. J. Jaworski
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT Phosphorus, as one of the biogenic elements, is a compound conditioning the life of organisms, as well as plays an important role in the industry. The processes related to the recycling of phosphorus compounds and closing the loop of it, result primarily from the financial situation (...)


THE ACTION OF NITRIC ACID ON LIGNIN IN A WATER–DIMETHYL SULFOXIDE MIXTURE (Papers SGEM2018)

V. Veshnyakov, M. Yokubjanov, Y. Khabaro
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT Lignin as a by-product of chemical or biochemical processing of wood is usually burned to generate energy. However, its use as a source of chemicals and materials is considered more promising. Treatment of lignin with nitric acid is used in practice for its depolymerization. In our (...)


THE IMPORTANCE OF TESTING WASTE MATERIALS FOR APPLICATION IN MODERN BUILDING COMPONENTS (Papers SGEM2018)

E. Terpakova
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT The utilization of different waste materials in concrete as partial replacement of cement or filler is having importance today, mainly on account of the improvements in the long-term durability of cement composites combined with ecological benefits. Fly ash (FA), Granulated Blast (...)


VALORIZATION OF MARINE ALGAE WASTE BIOMASS LOADED WITH ESSENTIAL METAL IONS IN REMEDIATION OF ANTHROPICALLY DEGRADED SOILS (Papers SGEM2018)

I. S. Badescu, D. Bulgariu, A. R. Lucaci, L. Bulgariu
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT In practice, the utilization of biosorption in the wastewater treatment systems at large scale is relatively difficult, mainly because the biosorbents have a short duration of use, and their regeneration is not always easy to achieve. Under these conditions, it is necessary to find (...)
