Abstract

Emisije ugljik (IV)-oksida, CO2, nastale iz antropogenih izvora,predstavljaju sve veći problem u smislu onečišćenja atmosfere te direktno utječu na klimatske promjene koje mogu ostaviti katastrofalne posljedice za planet i čovječanstvo. S ciljem smanjenja emisija štetnih plinova na globalnoj razini te razini članica EU donesena je zakonska regulativa kojom se nastoji ograničiti emisije stakleničkih plinva na razinu koja neće štetno djelovati na okoliš.Kyoto protokol, ratificiran od 55 država, definira smanjenje stakleničkih plinova: ugljik (IV)-oksida (CO2), metana (CH4), dušik (I)-oksida (N2O), klorofluorougljikovodika (HFC-i i PFC-i) i sumporovog heksafluorida (SF6).Direktivom 2003/87/EZ Europskog parlamenta i vijeća od 13.10.2003. definirano je trgovanje emisijskim jedinicama stakleničkih plinova unutar članica EU zajednice. Zakonski se obvezuje svako postrojenje koje proizvodnim procesom emitira stakleničke plinove, na izradu godišnjeg izvješća o emisijama nastalim tijekom proizvodnje.
U ovom radu dan je detaljan prikaz polugodišnjeg izračuna emisija CO2 za 2019. godinu koje nastaju tijekom proizvodnje čelika u čeličani ABS SISAK d.o.o.Nadalje,definirane su zakonske obveze čeličana, dan je opis procesa, definirani sutokovi izvora emisija te jedan iznos emisije otpadnog CO2 u elektrolučnoj peći, dobiven metodom proračuna.

Abstract (english)

Emissions of carbon dioxide, CO2, from anthropogenic sources are a growing problem in terms of air pollution and directly affect climate change, which can have catastrophic consequences for the planet. Therefore, many legal acts and international agreements have been signed in global to implement cleaner technology production and reduce greenhouse gas emissions.The Kyoto Protocol, ratified by 55 countries, defines the reduction of greenhouse gases: carbon (IV)-oxide (CO2), methane (CH), nitrogen (I) -oxide (N2O), chlorofluorocarbons (HFCs and PFCs) and sulfur hexafluoride (SF6). Directive 2003/87/EC of the European Parliament and of the Council of 13.10.2003.establishing a scheme for greenhouse gas emission allowance trading within the Member States.Every plant that emits greenhouse gases during the production process is legally obliged to prepare an annual report on emissions from production.

In this paper, a detailed overview of the semi-annual calculation of CO2 emissions for 2019. that occur during steel production in the steel plant ABS SISAK d.o.o. is presented. Furthermore, the legal obligations of steels, description of the process, the flows of emission sources and the amount of waste CO2 emissions in the electric arc furnace determined by the calculation method, are defined.
