The Cost

The possibility of using technical glasswork with liquid glass to produce aerated concrete using low-energy technology was considered in the paper. The unsorted technical glass cullet use as a part of aerated concrete will allow the non-decomposing industrial wastes disposal, which makes it possible to speak about the environmental technology development, while reducing the cost of producing effective heat-insulating materials considers its economic efficiency. The optimum liquid glass density was established upon aerated concrete mix receipt, which should be at least 1.23 and not more than 1.35 g / cm3. The technical characteristics of aerated concrete based on cullet and liquid glass obtained in this work are determined. Thermal conductivity of aerated concrete with its density of 150-400 kg / m3 is 0.06 W/m°C. The resulting aerated concrete is recommended for thermal insulation of pipelines both during construction and during their repair.

Ecological challenges encourage thinking about the quality of education, the need to develop a person who is responsible and able to live in harmony with the environment and is distinguished by ecological competences. The purpose of the research is to identify the ecological consciousness of pupils and values of pupils, which are developed based on the ‘Concept of the development of ecology and environmental technologies’. For the purpose of the research, a case study was applied, a quantitative research was carried out—the first school in Lithuania was analysed, where the concept of ecology and environmental technology development has been implemented since 2015. The research involved 11thand 12th grade pupils (N = 80). The results of the research were analysed using descriptive statistics, factor analysis, correlation analysis and comparison method.Keywords: Ecologic education, pupils, values, ecologic consciousness

Current State

River water quality degradation is one of the most significant environmental challenges. Over the years, many models have been used to investigate the current state of Malaysian rivers and its effects to the environment. River discharge is an important factor in water quality investigation. An integrative computational model, GIS coupled with SWAT model was being used to predict river discharge of this research. The simulation results in the period 1999 to 2010 represented fluctuation of discharge relatively well with both R2and NSI values were above 0.6. The results proved that the development of integrative GIS technology coupled with SWAT model is a good tool for environmental technology development in terms of investigating the current state of Langat river water quality as well as the capability of simulating the river discharge in the river basin. This shows that GIS-SWAT interface can be a reliable tool for water quality modeling in Malaysia in the future and further development on the software technology is a benefit for the water resources and environmental studies.

SummaryThis paper analyzes the justifications for governmental involvement in the development and commercialization of environmental technologies. To do so, a list of ‘generic’ rationales for government R&D involvement is extracted from various literature sources. Each rationale is discussed theoretically, and then analyzed in terms of its possible application to the environmental field. The intended contribution of the paper is to provide a theoretical background concerning the proper role of government in the development of environmental technologies. By determining the circumstances under which government involvement is justified, the groundwork is laid for the development of appropriate governmental policies.The paper argues that there are several salient features of the environmental field which may justify governmental involvement. The increasingly high degree of environmental regulation has already caused indirect market failures that hinder private R&D efforts. Potential technologies to counter environmental externalities represent public goods which have social benefits for which there are no incentives in the private market. Uncertainty due both to our lack of understanding of the complexities of the natural environment and to shifting environmental regulations and policies may cause a risk aversion in the private sector against developing technologies. Imperfect public knowledge concerning environmental issues leads to less than optimal demand for new environmental technologies. All of these features generate market distortions which cause private R&D to deviate from what is socially optimal. As a result, governmental involvement in environmental technology development may well be warranted.
