Abstract Gospodarenje otpadom predstavlja jedan od najvećih izazova suvremenog društva. Cilj
je ovog rada prikazati različite alternativne metode zbrinjavanja biootpada te analizirati
njihov utjecaj na sustav gospodarenja otpadom.
U radu su dane ključne informacije o biootpadu, od njegovog sastava, mogućih načina
obrade te potencijala kao resursa. Opisano je trenutno stanje u Republici Hrvatskoj, s
fokusom na obradi biootpada te aktualnim mjerama za poboljšanje stanja po tom pitanju.
U nastavku su objašnjene metode za smanjenje biootpada koje su usko vezane uz
prehrambene navike stanovništva, kao što je pravilno skladištenje hrane i ispravno
tumačenje deklaracija na proizvodima. U radu se, također, opisuju metode obrade
biootpada kao što je konvencionalno kompostiranje, bokashi kompostiranje,
vermikompostiranje, te je pobliže analizirana mogućnost ugradnje drobilica za hranu kao
načina obrade otpada od hrane u zgradama.
Analizirani su tehnički i ekonomski faktori ugradnje kuhinjskih drobilica za hranu te su
uz pomoć MS Excela izrađena 3 modela, u ovisnosti o postotku korisnika zainteresiranih
za ugradnju drobilica. Rezultat modela 1 pri 30% zainteresiranih korisnika pokazuje da
se količina biootpada prikupljena kamionima godišnje smanji za 534 t, što rezultira
godišnjem smanjenju troškova njegovog prikupljanja i zbrinjavanja od 56.358 €. Rezultat
modela 2 pri zainteresiranosti za ugradnju drobilica od 40% pokazuje smanjenje količina
biootpada od 720 t, rezultirajući uštedom na račun prikupljanja i zbrinjavanja biootpada
od 75.144 €. Rezultat modela 3 koji pretpostavlja najveći interes za ugradnju drobilica od
60% pokazuje da će se količina biootpada smanjiti za 1068 t, čime Čistoća štedi 75.144
€ na račun troškova sakupljanja i zbrinjavanja. Uz sufinanciranje projekta od strane Fonda
od 40% očekuje se povrat investicije za 7 godina. Rezultati su prikazani grafički te je
izveden zaključak s prijedlogom najoptimalnijeg smjera djelovanja.
Abstract (english) Nowadays, waste management represents one of the biggest challenges we face. The aim
of this paper is to present various alternative methods of biowaste disposal and to analyze
their impact on the waste management system.
Key information about biowaste is provided, including its composition, processing
methods and potential as a resource. Current situation in the Republic of Croatia is further
described, with emphasis on biowaste disposal strategies and current measures to improve
the situation. The following sections describe methods for reducing biowaste that are
closely related to the dietary habits of population, from proper food storage to correct
interpretation of product labels. The processing methods are then described, including
conventional composting, bokashi composting, vermicomposting, with the possibility of
installing food waste grinders in apartment buildings being further analysed.
Technical and economic factors for the implementation of food waste grinders is further
analysed, from which three models are created using MS Excel, each for different
percentages of interested users. The result of Model 1, with 30% of users interested in
food waste grinders installation, shows that the amount of bio-waste collected by trucks
annually would be reduced by 534 tons, resulting in annual cost savings of €56.358 for
its collection and disposal. The result of Model 2, with 40% interest in the installation of
grinders, shows a reduction in bio-waste of 720 tons, resulting in savings of €75.144 for
the collection and disposal of bio-waste. The result of Model 3, assuming the highest
interest in the installation of grinders at 60%, shows that the amount of bio-waste would
be reduced by 1.068 tons, saving €112.760 in collection and disposal costs. With 40% cofinancing
from the Fund, the investment payback period is expected to be 7 years. The
results are presented graphically, and a conclusion is drawn with a proposal for the most
optimal course of action.
