The civil engineering is one of the significant holders of permanent value to society. On the other hand, construction and demolition waste (CDW) generated during this activity presents 22% of the total waste stream in European Union [1]. However, this waste can be recycling through the existing technological methods and processes. Considering this fact, is necessary to begin to understand the waste as a source of secondary material, which allows the sawing of natural raw materials. The ways of treatment and subsequent use of construction and demolition waste (CDW) depends strongly of the demolition waste realization, because the construction and demolition waste arises mainly at this works. This paper deals with the possibilities of realization of demolition works and the consequent ways of recycled material use.

Construction and demolition waste (CDW) presents a quarter of total originated waste amount in the EU. It follows that the treatment and another reusing of CDW is a current subject within waste management not only in Slovakia, but also in other states of EU. The significant role belongs to a location of waste origin and location of waste treatment place at recycling of construction waste. The basic systems of CDW recycling and their environmental impact at surroundings area of recycling place are analyzed in the submitted paper. There is proposed a suitable way of CDW treatment and interest area estimate method of existed recycling plants following this analysis, location of sources, markets and economic parameters of recycling costs. The expression of attribute is based on the knowledge of distribution logistic, which is able to describe whole distribution system of CDW recycling, elements and their interaction, which are necessary for calculation of interest area. This expression of interest area provide an effective utilization of existed power, estimate of requires on increasing power, eventually modernization of recycling plants and building of recycling centre in uncovered areas.

Odpady budowlane i pochodzące z rozbiórki (CDW)stanowią jedną czwartą wszystkich odpadów w UE. Zatem utylizacja i ponowne zastosowanie takich odpadów jest aktualnym tematem w ramach zarządzania odpadami nie tylko na Słowacji, ale także w innych państwach UE. Istotną rolę w utylizacji odpadów budowlanych odgrywa lokalizacja źródła pochodzenia odpadów i lokalizacja miejsca utylizacji. Artykuł analizuje podstawowe systemy utylizacji odpadów budowlanych i pochodzących z rozbiórki oraz ich środowiskowy wpływ na obszar otaczający miejsce utylizacji. Proponuje się właściwy sposób uzdatniania odpadów budowlanych i pochodzących z rozbiórki oraz metodę szacowania obszaru zainteresowania istniejących zakładów utylizacji w oparciu o tę analizę, lokalizacje źródeł, rynki oraz parametry ekonomiczne kosztów utylizacji. Określenie atrybutu opiera się na znajomości logistyki dystrybucji, która pozwala opisać cały system utylizacji odpadów budowlanych i pochodzących z rozbiórki, a także elementy konieczne do oszacowania obszaru zainteresowania wraz z ich wzajemnym oddziaływaniem.

Preservation historical form of theatre building was the condition for its reconstruction. But there was made take reconstruction of the interior. The historical building was divided into 20. separated units with projects of reconstruction. Impossibility to do necessary technical exploration before re-construction has asked for division the building to individual technological units. Very pretentious chosen approach has asked for high level of a management activity and perfect technological job engineering. There was necessary to respect very strict requirements for protection of the environment during each stage of reconstruction. Situation of the site in centre zone of the city with eliminated traffic has asked for special measures. The basic condition was to preserve original interior decorative elements. Therefore was necessary to manage their remove and deposit. The elements which was not suitable to remove were covered by fire resistant means, to protect it against mechanical damage and dust. Peculiarity all technologies for reconstruction works was restriction for using of mechanisms. The most expressive it was manifested by demolition and ground works. The main processes of vertical and horizontal transport of material were made handle or by belt conveyer. After the basement of the building had been recovered, it has been founded absence of protection against soil moisture. The technology GFTK has been chosen for protection against water. That technology inters in press injecting of emulsion through injection jets with back-flow valve to prepared holes in basement. Beside solution of technological problems it was necessary to solve also ecological conditions of building processes. There was accepted primary and secondary measures were aimed to minimise influences to the environment by choice suitable technologies. The secondary measures are represented by usage of modern technologies and technical solutions. The goal is permanent improvement of the environment also after end of construction processes.
