Thermal insulation systems of ETICS are now mostly solved in the building industry, whether in terms of insulating the structures, choices of materials and subsequent recycling after the end of their life period. From the environmental point of view and also in the perspective of sustainable development, it is essential to look for other suitable material bases which relate only to easily renewable sources of raw materials or to industrial wastes which have long been available in sufficient quantity and quality. It is important that production of the insulation systems is energetically efficient modest in terms of manufacturing facilities. The aim of this paper is to verify the possibility of using natural insulation materials for thermal insulation systems ETICS. This paper describes the results of studies of key properties of insulations based on industrial hemp and flax and the results of computational simulations of the behavior of these insulations incorporated in the real systems ETICS.

A biorefinery integrated process based on lignocellulosic feedstock is especially interesting in rural areas with a high density of agricultural and agro-industrial wastes, which is the case for olive crop areas and their associated industries. In the region of Andalusia, in the south of Spain, the provinces of Jaén, Córdoba and Seville accumulate more than 70% of the olive wastes generated in Spain. Therefore, the valorisation of these wastes is a matter of interest from both an environmental and a social point of view. The olive biorefinery involves a multi-product process from different raw materials: olive leaves, exhausted olive pomace, olive stones and olive tree pruning residues. Biorefinery processes associated with these wastes would allow their valorisation to produce bioenergy and high value-added renewable products. In this work, using geographic information system tools, the biomass from olive crop fields, mills and olive pomace-extracting industries, where these wastes are generated, was determined and quantified in the study area. In addition, the vulnerability of the territory was evaluated through an environmental and territorial analysis that allowed for the determination of the reception capacity of the study area. Then, information layers corresponding to the availability of the four biomass wastes, and layers corresponding to the environmental fragility of the study area were overlapped and they resulted in an overall map. This made it possible to identify the best areas for the implementation of the biorefineries based on olive-derived biomass. Finally, as an example, three zones were selected for this purpose. These locations corresponded to low fragility areas with a high availability of biomass (more than 300,000 tons/year) in a 30 km radius, which would ensure the biomass supply.

The objective meaning of the sustainable development process in relation to the neo-industrialization of the economy is to create conditions for the restoration of the ecological identity of the national economy as a multi-industry production complex. We consider the neo-industrial development of the economy as the re-establishment of a competitive manufacturing complex in it, capable of saturating the domestic market avoiding increasing the burden on the environment with the innovative development of raw materials production, creating the material basis of national competitiveness in the environmental plan. From sustainable development point of view, neo-industrialization means conducting a comprehensive structural policy, the object of which should be national reproduction, and the subject is deep transformations of the processes that form the complex of human impact on nature, its institutional and technological structure, increasing the reproductive role of the green economy based on the potential of the internal market. At the same time, the history of greening industry, which dates back to the 1990s, testifies to the positive experience of replacing global production chains of raw materials, in particular, energy carriers, with the benefits of a fundamentally new type – alternative energy sources, biomaterials. Therefore, the development of technologically advanced manufacturing industry based on technologies of the green economy is possible as a result of the formation of production of goods and services that are maximally focused on meeting the environmental needs of society.

The Development Strategy

The concept of sustainable development in comparison with other paradigms was the most acceptable, from the point of view of determining the development strategy of society, in the medium and long term. Due to that, such important trends in science and practice as the restructuring and modernization of the economy, energy efficiency, environmental security, "green economy", etc. have been developed. One of the most important areas of research, important both for science and practice, is the measurement sustainability of development using the system of indicators. The quantitative measurement of sustainability makes it possible to shape strategies for the development of countries and regions, taking into account the ecological, social factors that previously could not even compete with economic factors. For Russia, this is important from different perspectives. Among the main reasons there is a significant differentiation of regions in terms of development level and the predominance of "raw materials" in the structure of the economy of many regions. Rational use of natural resources is a necessary condition for the sustainable development of any state or region.

Abstract Efforts were made to demonstrate that in biorefineries it is possible to manufacture all the commodities required for maintaining human civilisation on the current level. Biorefineries are based on processing biomass resulting from photosynthesis. From sugars, oils and proteins, a variety of food, feed, nutrients, pharmaceuticals, polymers, chemicals and fuels can further be produced. Production in biorefineries must be based on a few rules to fulfil sustainable development: all raw materials are derived from biomass, all products are biodegradable and production methods are in accordance with the principles of Green Chemistry and Clean Technology. The paper presents a summary of state-of-the-art concerning biorefineries, production methods and product range of leading companies in the world that are already implemented. Potential risks caused by the development of biorefineries, such as: insecurities of food and feed production, uncontrolled changes in global production profiles, monocultures, eutrophication, etc., were also highlighted in this paper. It was stressed that the sustainable development is not only an alternative point of view but is our condition to survive.

Building Industry

Recent studies have identified that buildings all over the world are great contributors to energy consumption and greenhouse gas emissions. The relationship between the building industry and environmental pollution is continuously discussed. The building industry includes many phases: extraction of raw materials, manufacturing, construction, use, and demolition. Each phase consumes a large amount of energy, and subsequent emissions are released. The life cycle energy assessment (LCEA) is a simplified version of the life cycle assessment (LCA) that focuses only on the evaluation of energy inputs for different phases of the life cycle. Operational energy is the energy required for day-to-day operation processes of buildings, such as heating, cooling and ventilation systems, lighting, as well as appliances. This use phase accounts for the largest portion of energy consumption of the life cycle of conventional buildings. In addition, energy performance certification of buildings is an obligation under current European legislation, which promotes efficient energy use, so it is necessary to ensure that the energy performance of the building is upgraded to meet minimum requirements. For this purpose, this work proposes the consideration of the energy impacts and material resources used in the operation phase of a building to calculate the contribution of these energy impacts as new variables for the energy performance certification. The application of this new approach to the evaluation of university buildings has been selected as a case study. From a methodological point of view, the approach relied on the energy consumption records obtained from energy and materials audit exercises with the aid of LCA databases. Taking into practice the proposed methodology, the primary energy impact and the related emissions were assessed to simplify the decision-making process for the energy certification of buildings. From the results obtained, it was concluded that the consumption of water and other consumable items (paper) are important from energy and environmental perspectives.

Since last decades both processes for the production of glass and ceramic materials (known by the generic name of "vitrification") and the processing of the usual ceramic materials ("sintering") are being investigated as a possible way to isolate, inmobilize and even recycling of industrial wastes as a source of "secondary raw materials". Starting from this point of view, the basis for the processing of some of wastes investigated by the author in the last decades are exposed, namely: metallurgy (muds or sludges...), residues from the production of energy (generation power plants, incinerators, nuclear power plants ...) wastes coming from the treatment of minerals and rocks (dumps, mine tailings, muds and machining of natural stone ...), as well as electrical wastes, demolition wastes and finally biomass residues which have been investigated in the recent years. This type of waste and mixtures give rise to synthetic materials with wide uses in construction and public works. Indeed, these are the only industries able to management of high volumes which may be suitable for absorbing a new range of glass, ceramic and glass-ceramic materials from all type of wastes. Experimental results obtained in last decades allow to conclude that both sintering processes as well as vitrification can be considered as an actual and useful, at least partially, for solving the environmental problems generated by all type of wastes.

In preparation for the World Summit on Sustainable Development (Johannesburg), almost all EU member-states and some accession countries presented their national strategies for sustainable development (NSSD) during the summer of 2002. Along with other countries, Hungary is only now setting up this important document. Everywhere during the last decade, as in the EU countries, the intention was to involve the environmental problems into other political questions (agricultural, energy and transport policy, etc.). Today the strategy-builders have given up the sectoral view because of difficulties and setbacks, and use a view aiming the problem.Agri-environmental issues appear as the elements of sustainability in the national strategies. For example, in accordance with the danger of global warming, the emission of green-house gasses of agriculture; in line with eco-efficiency, the production of renewable raw materials and energy sources originating from agriculture, and, in relation to changing lifestyle, food-safety and the future of biological agriculture will be disputed. With this study, I investigate the main characteristics of sustainable development strategies at both the EU level and at the level of the different member states from an agri-environmental point of view.

The urbanized population is increasing year by year, leaving fewer and fewer inhabitants in the province. This inevitably leads to increased energy and resource consumption, leading to environmental problems. All this, combined with climate change, calls for a more holistic approach to the provision of raw materials and resources in future cities, both in the main aspects of sustainable development, social, environmental and economic. From this point of view, vertical farms can be an instrument that addresses these aspects.
