Dynamic processes at the occurrence and development of a forest fire

Luben Elenkov

South-West University "Neofit Risky" Blagoevgrad

Abstract:

The dynamics of occurrence anddevelopment of aforest fire can be explained by the experiments that has taken place on the spot (range) and by similar laboratory tests. The key role is played by the convective upwardstream since the very occurrence, the intensive accelerating development until the loading on fire is overcome at an above-the-materials-on-fire height. The analysis of this convective stream reveals the objective laws that rule the spot fire development.

Katinka Mihova, Tsvetelina Simeonova

University of Forestry Sofia

Abstract:

Environmental management includes all activities aiming at improving the environmental performance of the companies. Main reasons for the organizations to include environmental principles in their corporate strategies are: to comply withthe local and international legal requirements as well as to meet the customer requirements, to improve their image, cost savings and greater market possibilities.

The environmental tools and approaches are growing in number and variety. One of the first andmost complex ones are the environmental management systems. After the international standard ISO 14001 and the ISO 14000 series was introduced as well the EU Eco-Management and Audit Scheme (EMAS). For the last 1215 years there is a significant interest in Europe and the standards have been developed and updated.

The environmental management is already playing an essential role in the companies. The effective waste management, energy and resource utilization can lead to cost savings in addition to the environmental benefits. Generally the improvement of the environmental performance of the companies is resulting in improved economic outcomes and competitiveness.

Green infrastructure is a concept originating in the mid-1990s of XXth century which emphasizes on interconnectivity of all natural components in the process of land use planning both in urban and rural environment. With this concept are connected many and diverse suggestions in the various professional activities like land use planning, landscape planning, landscape management, space planning, regional planning, urban planning, green systems planning etc. In particular there is an emphasis on the connection with the types of land and landscape. On the other hand with the idea for green infrastructure is emphasized on the insurance of life supporting functions and multifunctionality in the progress of planning, management and existence of space which associates it with the concept for sustainable development. The significance of this idea is confirmed and by the fact that the 46th World congress of the International Federation of Landscape Architects IFLA, held from 2123 October, 2009 in Rio de Janeiro, Brazil with theme Green Infrastructure: High Performance Landscapes.

CHARACTERIZATION OF THE INDUSTRIAL WASTES A COMPULSORY STAGE BEFORE THEIR UTILIZATION AND TREATMENT

Petar Petrov, Vania Kyoseva, Ivan Dombalov

University of Chemical Technology and Metallurgy Sofia

Abstract:

The utilization and treatment of the industrial wastes requires their characterization regarding their structural-mechanical, physical-chemical and toxicological properties.

The complete characterization enables the choice of the most appropriate methods for thermal or hydro-technological utilization of the wastes and the further landfilling of the utilization process residues.
