Application of the mathematical statistics for the evaluation of the waste incineration process

Abstract

The article deals with the research on the impacts of waste incineration processes on the environment within a particular region by the means of mathematical statistics. The area of interest for this case study considers the aspects of practical application of using the above methods and principles in order to reduce the environmental impacts of waste incineration process in the concrete region. The Pearson correlation coefficient r(xy) = 0.54 indicates that there is a moderate linear relationship, presented by a direct proportion between the values of incinerated waste quantity and the quantity values of produced heat. The statistics results show that the incineration during a one-year period produces about 15,266 tons of plastic and electrical components, and will release about 590,000 GJ of energy and about 199,000 tons of steam and 287 tons of other emissions with only 3 milligrams of dioxins. The mathematical statistics is used to analyse, and subsequently adjust and improve the waste incineration process in order to achieve the desired parameter values, specifically the calorific values, the amount of heat produced, and the amount of generated steam and air pollutants.

The results of mathematical statistics show that there is a direct relationship between the amount of incinerated waste (negative aspect) and the production of electricity (positive), but also the amount of heat produced (positive) and the amount of produced flue gas and ash (negative aspect).

The environmental assessments are an important step in building and implementing Environmental Management System (EMS), which consists of the development and evaluation of the analysis followed by the adoption of measures to remedy the deficiencies. The aim of the analysis of the environmental situation within the region of the case study company is a fact-finding in the field of protection of environment that affects the production and non-production operations, and should be monitored the manufacturing practice compliance of the company with the current legislation, the status of operational documentation, the status of internal and external communications in the area of the environmental protection, the responsibilities and liabilities between departments and employees.
