Opis:
The civilization progress entails an increasing demand for water. There are many different technologies for collecting water from alternative sources. An efficient and cost-effective solution is to use small tanks for rainwater runoff from rooftops. In this way, the harvested water can be successfully used to flush toilets, which stands for 30 percent of water consumption in households. The capacity of water tanks depends on the technical and economic possibilities. Using a dual flush system in toilets that allows for both rainwater and mains water usage can lead to a significant reduction in the tank size. In Bielsko-Biała, given its environment, one-family dwellings, a rainwater tank with a capacity of only 0.25 m3 per person and a roof area of 30 m2 per person, it is possible to save almost 80 percent of treated mains water used in toilet flushing. It constitutes over 10 m3 of water per person per year. A nomogram made for choosing the right tank according to the roof area and tank capacity allows assessing the possibilities in terms of drinking water savings in any building in the environment of Bielsko-Biała.

Opis:
Water is essential to the proper functioning of kindergartens and schools. Nevertheless, water consumption in public facilities is usually high, often exceeding the average household water consumption. Recently, increasing pressure on this valuable and depletable natural resource has been noticed and, therefore, it is interesting to study the water consumption in kindergartens and the possibilities of water saving. The present work examined 6 kindergarten facilities in Kyjov, Czech Republic, where the equipment has been enhanced with the faucet water saving technology. The work analyzed the impact of the equipment on the reduction of water consumption as a raw material and on the financial and economic profitability. The results were estimated based on the variation of two parameters such as average daily water consumption and demand per person. The experiment showed that installing the savers resulted in water savings ranging from 8% to 18.7% for average daily consumption and from 10.02% to 23.2% for per capita demand.

Opis:
The issue of electric energy saving in public transport is currently becoming a key area of interest, a fact connected with both an increase in society’s environmental awareness and a rise in the prices of fuel and electricity. Electricity can be saved by reducing transmission losses in the supply system. The article presents a method of measurement and analysis of transmission losses in the supply system of electrified public transport on the example of trolleybus transport in Gdynia and Lublin in Poland.

Opis:
Development of new and modification of existing chemicals, which act not only as binders, but also provide increased retention of fiber and other pulp components on the paper machine grid, accelerate pulp dehydration, and provide special properties (moisture resistance, heat resistance, improvement of other technical characteristics of paper and cardboard) of paper and cardboard, is an important and urgent task of chemical technology and ecology. This paper presents results of the corn starch modification with epoxypropyltriethanolammonium chloride, hexamethylolmelamine and hexamethylenetetramine. Modified starches provide the necessary strength indicators of cardboard from waste paper and low turbidity of wastewater. The obtained starches can be used in mills that use low-quality waste paper for the production of cardboard and paper products with the aim of saving fiber, reducing wastewater pollution and as a result reducing the negative impact on the environment.
