Abstract

Termoelektrane na ugljen proizvode velike količine energije, ali i mnogo otpadnog pepela ugljena koji onečišćuje okoliš. Cilj ovog seminara je prikazati utjecaj čestica otpadnog pepela ugljena s odlagališta otpada na okoliš. U seminaru se također opisuju i procesi kroz koje odloženi otpadni pepeo prolazi u međudjelovanju s okolišem, kao i načini recikliranja i ponovne uporabe otpadnog pepela ugljena i njihov posljedični utjecaj na okoliš.
Proizvodnja otpada diljem svijeta je u porastu, a industrijske zemlje se sve više okreću spaljivanju kao jednom od načina upravljanja komunalnim otpadom. Glavna prednost spaljivanja takvog otpada je smanjenje njegovog volumena i potencijalna proizvodnja energije, no otpadni pepeo koji preostaje nakon termičke obrade sadrži onečišćujuće čestice pepela koje su nepogodne za okoliš i ljude.
Tijekom posljednjih desetljeća postignut je važan napredak u integriranim sustavima gospodarenja otpadom. Postoje mjere ublažavanja utjecaja otpada na okoliš koje se posebno usredotočuju na smanjivanje prijetnji našem zdravlju i okolišu. Većinu prijetnji okolišu i zdravlju uzrokuju metali i soli uslijed procjeđivanja vode, zračnog prijenosa čestica i stvaranja potencijalno opasnih plinova. Krajnji cilj savladavanja gospodarenja otpadom bi trebalo biti umanjeno i kontrolirano ispuštanje onečišćujućih tvari u okoliš u neopasnim količinama za njega i zdravlje ljudi bez ikakve naknadne intervencije i recikliranje otpada u nove proizvode koji ne predstavljaju daljnju opasnost onečišćenja.

Abstract (english)

Coal-fired power plants produce large amounts of energy, as well as a lot of coal ash waste that pollutes the environment. The aim of this seminar is to show the impact of coal ash waste particles from landfills on the environment. It also describes interaction processes between waste ash and the environment, as well as ways of recycling and reusing coal ash and the subsequential impact of these processes and recycled products on the environment.
Waste production around the world is increasing and industrialized countries are turning to incineration as a way of managing municipal waste. The main advantage of incinerating such waste is the reduction of its volume and possible energy production, but the remaining waste after incineration contains coal fly ash particles that are harmful to the environment and people.
During the last decades, important progress has been made in integrated waste management systems. There are environmental mitigation measures that specifically focus on reducing hazards to our health and the environment. Metals and salts cause most threats to the environment and our health due to water seepage, airborne particle emissions and production of potentially toxic gases by which they are spread outside of landfills. The ultimate goal of managing waste is to reduce and control the release of polluting particles into the environment in non-hazardous quantities without any subsequent intervention and recycling waste into new non-hazardous products.
