Abstract

Energija biomase smatra se obnovljivim izvorom energije, no postavlja se pitanje spada li tu stvarno, uz sve negativne utjecaje koje ima na okoliš. Glavni nedostatci biomase su: promjena načina korištenja zemljišta i indirektne emisije $ CO_2 $, uništavanje ekosustava, nestabilnost prinosa sirovine, skupoća i niska učinkovitost tehnologija prerade sirovina u goriva, niska ogrjevna vrijednost dobivenih goriva te emisije stakleničkih plinova prilikom transporta sirovina zbog kojih nije $ CO_2 $ neutralna. Biomasa ima i svoje pozitivne strane: uzgojem energetskih usjeva kupi se iz zraka $ CO_2 $ i sprječava se propadanje napuštenih poljoprivrednih zemljišta, a korištenjem otpada smanjuju se emisije stakleničkih plinova u atmosferu. Ulaganjem u razvoj elektrana na biomasu i odgovornim ponašanjem prema okolišu većina njenih negativnih utjecaja bi se trebala eliminirati.

Abstract (english)

Biomass energy is considered a renewable energy source, but the question is asked weather it really belongs there, with all its negative impacts on the environment. Main disadvantages of biomass are: land use change and indirect $ CO_2 $ emissions, ecosystems destruction, instability of feedstuff yield, expensiveness and low efficiency of fuel conversion technologies, low heating values of resulting fuels and greenhouse gas emissions during transport of fuel which makes it not $ CO_2 $ neutral. Biomass also has its positive sides: biosequestration of $ CO_2 $ during growth of energy crops, prevention of degradation of deserted agricultural lands and using waste as fuel lowers greenhouse emissions. Investing in development of biomass power plants and responsible environmental management should eliminate most of the negative impacts of biomass.
