ROI model for mobile crushing under the 2025 Serbian Waste Management Law and rising landfill gate fees.
Landfill fee €25/t, fuel consumption 0.27 l/t, and wear factor 0.85 are locked into the shift model.

tensile fracturetensile fractureTensile fracture: a material failure mode where the shredder shafts pull and tear the feed material apart, dominant at high RPM and low specific loads., cutting regimecutting regimeCutting regime: the operating mode where the shaft blades slice through feed material with a shearing action, preferred for clean fraction output., TCOTCOTotal Cost of Ownership: the comprehensive lifetime cost including purchase price, fuel, wear parts, maintenance, and residual value depreciation., OPEXOPEXOperational Expenditure: recurring costs of running the shredder — fuel or electricity, wear part replacement, scheduled servicing, and operator wages. — wear cassettewear cassetteWear cassette: a modular, replaceable cutting insert set mounted on the shredder shaft.

The Official Gazette of the RS No. 109/2025 formalized the current enforcement framework and made material recovery a mandatory operating condition. Serbia's alignment with EU Chapter 27 has accelerated the move away from linear disposal, and landfill gate fees now routinely reach €25/t, creating acute financial pressure on demolition contractors.
Lifecycle adjustment: $W_{lifecycle}=0.85$. The high-silicate content of the New Belgrade demolition sector (Socialist-era reinforced concrete) acts as a high-abrasion constant $k_{abr}$, increasing tool wear by 15% compared to standard EU aggregate. Deploying the Impaktor 250 EVO on-site transforms a liability into an asset. Processing 5,000 tons of CDW eliminates €125,000 in gate fees, effectively making the produced aggregate a 100% net-profit commodity. The machine bypasses heavy-haul logistics and converts the demolition stream into a monetized recovery cycle.
At an operational burn rate of just 0.27 liters of diesel per ton of concrete, the cost of processing is mathematically negligible compared to state-mandated dumping penalties. The ROI breakeven point is aggressively short.
