The objective of this paper is to present a new binder system that can be applied in composite rocket pro-pellants to improve the properties of these propellants, not only for better performance but also to reduce waste and pollution. This novel system is based on the oxygenated thermoplastic elastomer (TPE) binder, which consists of a multi-block segmented polyether-b-block amide (PEBA) copolymer (alternating hard and soft segments) with the addition of a plasticizer, wetting agent, and an anti-oxidant. A series of tests were conducted to determine the properties of solid rocket propellants based on this binder system. The effect of the novel TPE binder system on the burning rate and mechanical properties of ammonium perchlorate (AP)-based propellants is demonstrated. Also, the thermal behavior of these propellant compositions was studied. The results show that propellants based on the novel TPE binder have a better energy performance than today's workhorse hydroxyl-terminated polybutadine/AP propellant, possess appropriate mechanical properties, and exhibit good processing and aging characteristics at low cost. © 2010 by Begell House, Inc.

This study seeks to identify the key trends and important knowledge towards biomass and biofuels sustainability using a global assessment. The biomass is considered as the fourth largest energy source in the world after coal, oil and natural gas. It is very important to select the most promising option for using biomass under environmental, economic and resource perspective. While the electricity and heat can be provided by variety of renewable resources such as wind, sun, water, biomass, etc., the biomass showed to be the only alternative for production of transportation fuels. But biomass potential for energy production is promising nowadays. It became the most important renewable energy resource with about 10% of the annual global primary energy demand. The biomass energy has potential to be 'modernised' worldwide due to the easiest way of conversion into the most convenient forms such as gases, liquids, or electricity. This paper reviews the latest literature on biomass resources and biofuel production potential with a spatial focus on global sustainability challenge. A number of scenarios world-wide, estimating the current and future development of biomass and biofuel sustainability challenge including the case of Croatia and Kosova are given. Great amount of research is focused on the challenges of growing and harvesting the biomass use for the energy and biofuel production, sustainability of production operations and various trade possibilities. The overview shows that biomass and biofuel sustainability is influenced by several factors that affect the food security as well as socio-economic impacts. The harmonisation of well working sustainability framework and strong policy measures are essential with consideration on the impact assessment that examines the economic and environmental effects of biomass and biofuel use.

In Albania has already grown a big ambition for mushroom production and it is reasonable to study the effect of residues coming from this activity and finding the proper way to profit useful components. For every kilogram (kg) of mushroom produced, about 5 kg of SMS is generated and, traditionally, has been discarded as waste. The fast increase in mushroom production worldwide has resulted in large quantities of SMS. These great amounts of waste can cause environmental problems, which has led to increased research to develop technologies for treating wasted spent mushroom. Spent mushroom substrate (SMS) is the substrate left over after mushroom harvesting.

The paper will address the strategic management of local governance policy and waste management practices in the municipality of Prishtina. Rapid urbanization has made waste management a serious problem today. The perception of the people has always been that it is a responsibility of the local government bodies. This paper will include the evaluation of available and practical alternatives and techniques, initiating a practical waste recycling methodology, and promoting 3R, Reduce, Reuse and Recycle waste and improve the management in the waste sector for the local municipality level.

Large amount of organic domestic waste, gardens, stables, and fast decomposition time, inadequate treatment (except in the landfill), makes their harmful impact on environment. Research on the generation of organic waste is made in summer, in three areas of the city, which differ by socio-economic structure. The methodology of data collection and data processing was carried out with measurements of kitchen organic waste in these areas for 21 days in a row, 7 families were engaged from each area, organic waste was collected separately from other wastes and then they were weighted. The research was focused on data collection of organic domestic waste and established methods of their treatment. From the measurements and calculations made, the amount of organic domestic waste produced in this season is approximately 252 g/inh/day or 77% of the total quantity of municipality waste, this amount varies depending on the seasons when measurements was made but it does not fall below 35%. In general, the amount of organic waste in Kosovo includes organic stables and gardens waste, but they are not included in this paper.

This paper addresses the issue of emergency response and risk management- in the countries of South-Eastern Europe (SEE). A number of multilateral environmental agreements have been adopted by countries of SEE in order to better prevent disasters and reduce their consequences. However, those texts aim at strengthening international cooperation for emergency relief after environmental disasters (industrial or natural). In the light of considering the implementation of international obligations at the national level, the state of legislative and institutional framework in SEE is analysed and some specific actions are proposed. © Springer Science+Business Media B.V. 2011.

Coal, as an important source of energy, is very often the subject of study for scientists from the areas of chemistry, physics, technology, and biology, etc. In Kosovo, large deposits of coal, in the form of lignite, can be found. Lignite is mostly used to produce electrical energy; however, the interest of the country of Kosovo is to study many of the aspects of lignite. In this paper an analysis of the microflora of lignite from the mine in the locality of Mirash, near Kastriot, is presented. With modern microbiological methods, the density, assortment, and some of the morphological and physiological characteristics of bacteria (heterotrophic, proteolytic, amilolytics, lypolytic and celulolytic) were determined and aerobic bacteria and fungi (yeasts and moulds) were investigated also. The samples of lignite were analyzed for physic-chemical attributes, for example, a determination of ash, and of C, O, H, N, S, carbonates, silicates, etc. The biomass of the isolated microflora from lignite was submitted for a chemical analysis and an astounding number of bacterial microflora and fungal was found. A composition chemical link between the coal and the microbial biomass was observed: the values of C, O, N, and H were found to be approximately similar in the coal and the bacterial mass.
