Production of building materials is mostly energy consuming. In the sphere of insulation materials we mostly see rock wool based materials or foam-plastic materials whose production process is demanding from material aspect and raw materials aspect as well. At present the demand for thermal insulation materials has been growing globally. The thermal insulation materials form integral part of all constructions in civil engineering. The materials mainly fulfill the thermal insulating functions and also the sound-insulating one. The majority of thermal insulation materials are able to fulfill both of the functions simultaneously. The paper describes questions of thermal insulation materials development with good sound properties based on natural fibres that represent a quickly renewable source of raw materials coming from agriculture. The main advantage of the materials are mainly the local availability and simple renewability of the raw materials. In addition an easy recycling of the materials after their service life end in the building construction and last but not least also the connection of human friendly properties of organic materials with advanced product manufacture qualities of modern insulation materials.

Horticultural Research

The National Horticultural Research Institute coordinates many projects designed to boost and improve the use of various fruits and vegetables around Nigeria. To achieve the set goals for fruit processing, projects are undertaken in cooperation with selected laboratories. Based on the depth of work required for transforming research results into patented products, university and industry were involved in a collaborative assignment in sweet orange concentrate research and development. The work covered engineering and product testing, packaging, and sensory experiments in which materials and resources were shared at the participating center. This presentation focuses on guidelines for overcoming the problems associated with collaborative studies in developing countries and suggestions on funding components.

Abstract Non-cellulosic polysaccharides (NCP) from bark offer large potential as a class of natural raw materials for functional materials development and production of biochemicals. We have elaborated a process for sequential extraction of NCP from industrial Norway spruce bark using an accelerated solvent extraction (ASE) with water at 100 to 160°C. Carbohydrates, Klason lignin and ash content as well as size-exclusion chromatography (SEC) analyses were performed for all hot-water extracts. NCP were mainly composed of glucose, arabinose and galacturonic acid units which revealed the presence of starch, arabinose-rich hemicelluloses and pectins. In total, the industrial bark of Norway spruce contained up to 20% of NCP which were extracted with pressurized hot water. NCP were mainly extractable at 140°C and started to undergo degradation at higher temperature.

The purpose of the research is to substantiate the methodology for a comprehensive evaluation of the efficiency of investment projects in the format of concession agreements implemented in Russia’s regions specializing in mineral and raw materials development by considering the direct economic results of investment and indirect ones aimed at assessing the social and environmental indicators of industry production. Author’s results. The current state of the methodology for a comprehensive assessment of the efficiency of investment projects based on PPP principles in the Russian Federation and abroad was analyzed reflecting the economic aspects of the liberal concept of development, the provisions of the theory of stakeholders and based on the principles of public-private partnership. Methodological approaches were developed for evaluating comprehensively the efficiency of investment projects in the format of concession agreements implemented in the Russian regions of mineral and raw materials specialization, which considers both direct investment results and indirect, environmental and social ones.
