One of the important features of urbanization is the replacement of the original natural soil and vegetation by impermeable pavements, resulting in the changes of the permeability of natural soil and vegetation and bringing a series of ecological future trouble. Since the hard urban pavement occupies a considerably percentage of the whole area, its ecological environmental effect plays a very important role in the overall ecological environment of the city. As a result, the application of permeable pavements is an effective way to solve the problem of urban pavement ecological environment. This paper analyzed the environmental benefits of the permeable pavement and proposed the principles and technical measures about ecology regression of pavement. The measures contain maintaining the permeability of the water penetrate paths, establishing the criterion of the design and construction for penetrative pavements, improving the maintain technologies and so on.

AbstractRenewable energy sources (RES) become more and more popular. In Poland, biomass has the highest energy potential among all RES. Methane fermentation is one of possible ways to use it. The aim of the study was to perform energy and economic calculations for the biogas plant installation project in an existing farm situated in the Wielkopolska voivodeship. Because of the small area of the farm and the type of production, the calculations were carried out for micro-installation biogas plants. During the preparation of the project the production potential of the substrates was determined, allowing for further analyses. It was calculated that the electrical power of the designed biogas plant was 8.10 kW, with a total annual production of biogas at 29 471 m3. The obtained amount allows to generate in the cogeneration system 66 450 kWh of electricity and 71 190 kWh of heat energy. Some of the energy produced can be used on the farm and its surplus sold to the grid, which will allow for financial and environmental benefits.

Greenhouse Gas Inventories

This research aimed to evaluate the management of a Sewage Treatment Plant (STP) and the existing biogas plant. A mathematical model was used to analyze the behavior of methane, biogas production and energy generation potential for a period of three years at the Jacuípe II Treatment Plant, located in northeastern Brazil. If the biogas plant were in operation, it would be possible to obtain autonomy for energy generation in the years 2016 and 2018. Greenhouse Gas Inventories - GHG, situational diagnosis of the biogas plant and scenario of financial losses with the deactivation of the plant were prepared. The results revealed that the emission of 1,958.38 tCH4 could have been avoided with the use of an energy generator (85% less than that emitted) or 1,151.99 tCH4 (50% less than emitted), if combustion by burner/flare. In addition, the financial loss due to the inactivity of the biogas plant resulted in US$ 154,162.38, about 67% of the actual energy expenditure of the plant in the period from 2016 to 2018. The reactivation of the biogas plant present in this station will bring environmental benefits, since the emission of GHG will be mitigated, in addition to financial benefits, since the energy use of biogas in the plant will provide a reduction in the expenses with electricity from STP Jacuípe II, in line with the aspects of sustainability.

Taking into consideration the complexity of the new, heterogeneous, and different training needs currently present in the classrooms, the school is called to respond them in an effective and concrete way through inclusive educational approaches centered on the students, none excluded. On this basis, the authors, supporting the importance of technology in innovative teaching, propose the design and construction of an intelligent white stick through an inclusive cooperative methodology. The presented device, presented in this paper, is inspired by an open and collaborative teaching, enhancing a responsible digital education, accepting the training needs of all the students present in the classroom, specifically the blind student, and the recognition of the diversity in view of the reduction of disability.

The purpose of this study is to analyse the environmental benefits of precision agriculture technology adoption obtained from the mitigation of negative environmental impacts of agricultural inputs in modern farming. Our literature review of the environmental benefits related to the adoption of precision agriculture solutions is aimed at raising farmers' and other stakeholders' awareness of the actual environmental impacts from this set of new technologies. Existing studies were categorised according to the environmental impacts of different agricultural activities: nitrogen application, lime application, pesticide application, manure application and herbicide application. Our findings highlighted the effects of the reduction of input application rates and the consequent impacts on climate, soil, water and biodiversity. Policy makers can benefit from the outcomes of this study developing an understanding of the environmental impact of precision agriculture in order to promote and support initiatives aimed at fostering sustainable agriculture.
