Potrebno se je zavedati, da je:
- azbest zdravju škodljv,

izogniti le z doslednim upoštevanjem varnostnih

agregata
• Reciklirani agregati so heterogeni po sestavi,
kakovost zelo variira.
• Visokokakovostni, po meri narejeni kompoziti

• Tehnike, ki bi lahko izboljšale kakovost (npr.
pranje, magneti, zračni curek,) se praktično
ne uporabljajo.

Velik sinergističen efekt je možno doseči zlasti na
področju gradbeništva - vezanih kompozitov!
•Možno je porabiti velike količine odpadkov.
• Novi kompoziti so lahko boljši/ cenejši od
tradicionalnih.
• Toksične snovi v odpadkih se dolgoročno fiksirajo.
• Nižje CO2 emisije.
• Prihranek energije.
• Ohranjanje naravnih virov.

Gradbeni odpadki
EU Direktiva o odpadkih 2008/98/EC zahteva
bolj učinkovito recikliranje.
Eksplicitno za gradbene odpadke: 70 % do 2020.
Stopnja recikliranja v Sloveniji: 20 % ?

Situacija v Sloveniji
Stopnja recikliranja je nizka.
• Naravne surovine: v obilju, cenene.
• Deponije (nelegalno odlaganje).
• Pomanjkanje znanja in volje uporabljati odpadke.
• Komplicirane administrativne procedure.
• Ljudje še niso pripoznali: odpadek je surovina.
• Ljudje ne sprejemajo strokovnih dejstev / raje imajo
polresnice in domneve.
• Mediji poročajo katastrofično, senzacionalistično,
manipulistično.

Tehnični razlogi
Manjka holističen pristop v celotni verigi, od
rušenja do končne uporabe!
•Predrušitvena ocena je slaba (detekcija nevarnih,
kontaminiranih materialov, tudi predmetov, ki
imajo “re-use” vrednost ).
•Rušenje je takšno, da ne daje kakovostnih
materialov .
•Aplikacijo odpadkov v gradbenih kompozitih je
potrebno validirati → začetni stroški so višji →
stališče “to se ne izplača“.

Kako intenzivirati uporabo?
1. Izobraževanje odločevalcev in projektantov.
2. Pospeševanje v okviru zelenih javnih naročil.
3. Sankcioniranje ilegalnega odlaganja in plenjenja
naravnih virov.
4. Dvig motivacije in zavedanja laične javnosti:
- uporaba odpadkov je priložnost in potreba,
- odpadki so odlična surovina,
- ob korektni uporabi ne obremenjujejo okolja,
- zmanjša se potreba po energiji in naravnih
surovinah.
