By mixing the sewage biodegradable sludge and biomass ash a stable composite is formed. A study showed that, in this way, a building material with a compressive strength of about 2 MPa is produced, which can be used mainly for landfill covers, road-shoulder management, road-base stabilization and rehabilitation of degraded areas. An analysis of the chemical composition of the water eluate from the composite showed that the new composite material is inert and, as such, does not pose a threat and does not burden the environment. From the sustainable-development point of view this kind of waste-residue management presents an optimum - a zero waste solution. Z mešanjem komunalnega biomulja in pepela biomase se tvori stabilen kompozit. Raziskave so pokazale, da tako pridobljen gradbeni material s tlačno trdnostjo okoli 2 MPa lahko uporabimo na območju deponij komunalnih odpadkov za dnevne in končne prekrivke, za ureditev brežin in bankin, pa tudi kot podlago za gradnjo transportnih poti in sanacijo degradiranih območij. Tudi analiza kemične sestave izlužka iz kompozita je pokazala, da je novi kompozit inerten in kot takšen ne obremenjuje okolja. Z vidika trajnostnega razvoja je takšna rešitev optimalna, saj je rezultat predelave uporaben produkt (predelava "zero waste"). |
