This paper focuses on introducing new, environmentally friendly types of drivetrains in the field of bus transport. Main goal is to present approximate costs of purchase and cost of operating (especially fuels or electricity) and connected them with real emissions of carbon dioxide for each different technology of drivetrain, including Well-to-Tank and Tank-to-Wheel emissions. The authors are using the Weighted Sum Approach method to determine currently the most suitable drivetrain for urban busses.

The article presents the results of experiments on the use of the aquaponics method. Aquatic animals release products toxic to them themselves: nitrogenous, phosphorus, potassium compounds, carbon dioxide. The accumulation of these substances in water is the main problem as in closed industrial aquaculture. The same substances are absolutely necessary in hydroponics and they are added to water to obtain nutrient solutions for plants. Given that environmentally friendly products are increasingly popular and demand for them is constantly growing, there are prospects for introducing this innovation in the southern regions of Russia. Due to an increase in parsley yields in the aquaponic plant by 7.3%, an additional profit was received 4.8 rubles from 1 square meters.

Biogas Purification

<p>Purifying biogas from CO2 (carbon dioxide) and H2S (hydrogen sulfide) needs to be done to improve the quality of the biogas in the fuel. The presence of H2S in biogas can cause corrosive to the equipment, in addition to this, H2S is also dangerous for human and animal health. CO2 contained in Biogas is also an impurity that can cause corrosive beside H2S so the contained in biogas is also an impurity that can cause corrosive, so the purification process needs to be done in order to qualify biogas as natural gas which environmentally friendly and safe for health. The basic ingredient of biogas purification using water scrubbers base ingredients are water, which flowed pressurized biogas purification column from the bottom, of the column in order to reduce CO2 and H2S gases. The result of purification by using this method was that the levels of H2S in biogas reduced by 32.8 % while the CO2 content decreased by 21.2 %. It can be concluded that the H2S gas more soluble in the water compared with CO2, as H2S gas has higher efficiency removal from CO2. </p><p><strong>Keywords</strong>: biogas; carbon dioxide; hydrogen sulfide, waters scrubber</p>

Medium Voltage Switchgear

In today’s medium voltage switchgear SF6 is commonly used as insulating and arc quenching medium. Because of its high potential impact on the environment a substitution with an environmentally friendly alternative is pursued. In this paper the influence of the mixing ratio of carbon dioxide nitrogen mixtures as filling gas on the interruption capability in medium voltage load break switches is investigated. The interruption capability is regarded by means of the thermal interruption performance as well as the dielectric recovery of a model load break switch. The model load break switch allows an axial arc blowing with variable pressure and uses an exchangeable nozzle system.

The solution to the problem of large industrial cities with a developed metallurgical industry is the creation of environmentally friendly conditions for the life of the population through the disposal of industrial waste. The studies carried out have shown that the developed technology makes it possible to widely use steel-making slags and carbon dioxide emitted into the atmosphere in the production of small-piece wall stones with high operational properties. It is shown that only slag is required to obtain wall material without the use of a hydraulic binder.

Sustainable Planning

Diminishing natural resources have increased the prominence and implementation of approaches to sustainable planning, design, and application. Green schools minimize environmental impact by promoting environmentally friendly attitudes, reducing the need for infrastructure facilities, and using recycling as a strategy both during and after their construction. As with other green buildings, green schools reduce dependency on fossil fuels and thus limit the emission of carbon dioxide and other pollutants. Concerning global warming, green schools have the capacity to “turn back time,” creating learning circles that elicit solutions from their student bodies. In this chapter, the authors explore the economic, ecological, and social dimensions of green schools by means of a case study of an education campus in Adana, Turkey. The authors aim to elucidate how green schools may be effective in the conservation of future resources in architectural sustainability.
