Abstract

The article discusses issues related to the impact of incineration on human health and the environment. The aim of the work is to make a broad overview of the existing literature in this area. The problem was described in the literature based on a number of waste incineration plants studies in both Europe and all around the world. Subjects analyzed in the literature were risks at workplace, both administrative ones and directly related to the process of thermal treatment of waste. These risks result among others from the atmospheric emissions of many pollutants, including most of all polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans, heavy metals and some volatile organic compounds. The results of these studies will be an important argument in the discussion on the possible risks to humans and the environment posed by waste incineration plants and the expediency of building waste incinerators in Poland.

Abstract

Analysis of the distribution of CO2 concentrations was performed for a water-and-steam boiler plant located in a detached building supplying thermal energy to a hospital. The boiler plant was equipped with two low-temperature boilers and one high-temperature steam boiler. The maximum thermal energy demand of the hospital was 4280, 3500 kW of which came from the hot-water boilers and the remaining 780 kW from the steam boiler. Due to the operating system there were no permanent job positions in the boiler plant. Servicing consisted only in the supervision, periodic adjustment and maintenance of the equipment. These kinds of working conditions release the employer from the necessity to perform tests and measurements of working conditions in such a building. On the other hand, continuous measurements are made because of the installation safety and emissions of pollutants into the environment. The article presents results of the measurements and analysis of the distribution of CO2 concentrations inside and outside a small boiler plant, due to which it was found that the level of carbon dioxide concentration did not depend on the ambient air temperature. The resulting values are similar regardless of whether the measurements were taken in December 2012 or April 2013. However, there is an evident impact of seasons on the concentrations in the indoor air associated primarily with the demand for heat during the given period, the stay of people in the workplace and the number of working devices.

Abstract

Life Cycle Assessment (LCA) is one of the new, little more popular in Poland of elements of environmental management. In the world literature one can find many examples of the use of LCA but mainly for comparison purposes. The paper presents results of LCA analysis made on the basis of data from a running incineration of sewage sludge. Performing a thorough analysis of this process enables improved operational system, including through a better use of the resulting products of combustion, as well as determining the impact of the thermal treatment of sludge on the environment and compared the results with data from the literature. To date, in Poland has not been carried out environmental impact assessments and the process of thermal treatment of both sludge and waste, based on the assumptions of LCA.
