THE 0.27 L/T FUEL FLOOR
The 0.27 litres-per-tonne figure published for the ARJES Impaktor 250 EVO II is the lowest published diesel fuel consumption benchmark for a mobile slow-speed shredder processing standard construction and demolition waste. The figure is measured under the ARJES in-house test protocol (vol. 4, 2026) on a mixed C&D stream: 40% concrete, 25% brick, 20% asphalt, 10% wood, 5% metals and miscellaneous, at a throughput of 35 t/h and a feed particle size of 0–400 mm. The benchmark reflects the platform's two fuel-saving architectural choices: (1) the Volvo Penta TAD581VE Stage V engine's high-efficiency common-rail injection, which holds specific fuel consumption at 198 g/kWh across the 60–85% load band where the shredder operates; (2) the asynchronous dual-shaft kinematic that maintains cutting torque at low engine RPM, allowing the engine to operate at its BSFC (brake specific fuel consumption) sweet spot rather than high-RPM torque reserves. The 0.27 l/t figure is not a marketing peak — it is the sustained operating-point consumption under standard C&D load.
COMPETITOR FUEL LANDSCAPE
The 2026 competitor dataset places single-shaft and kinetic-drum mobile shredders at 2.9–3.9x the ARJES fuel benchmark. The Haas Tyron 1500 — a single-shaft diesel shredder with a 220 kW Cummins QSB6.7 Stage V — publishes 0.78 l/t on the same mixed C&D stream. The fuel premium reflects the single-shaft kinematic's higher reversibility frequency: every rebar-wrap or hard-object incident triggers a reverse-and-clear cycle that burns fuel without producing throughput. The Pronar MRW 2.85 — a dual-shaft diesel competitor architecturally closer to ARJES — publishes 0.92 l/t, the higher figure reflecting the smaller-diameter shafts (lower torque per shaft revolution) and the 248 kW engine operating further from its BSFC sweet spot under C&D load. The Komptech Terminator 6000 — a single-shaft 355 kW electric with a diesel auxiliary pack for sites without grid access — publishes 1.05 l/t when running on diesel auxiliary, reflecting both the single-shaft reversibility penalty and the auxiliary pack's lower efficiency compared to a direct-drive main engine. Across the four competitors, no diesel mobile shredder in the 2026 dataset beats 0.78 l/t.
ANNUALISED FUEL ECONOMICS — 58,500 EUR/YR DELTA
For a CEE demolition contractor processing 50,000 tonnes of C&D waste per year (the typical throughput for a single-shredder fleet on a 5-site annual profile), the fuel cost delta is decisive. At the Q3 2026 EU industrial diesel price of 1.50 EUR/l (including excise, excluding VAT): ARJES Impaktor 250 EVO II annual fuel cost = 50,000 t × 0.27 l/t × 1.50 EUR/l = 20,250 EUR. Komptech Terminator 6000 annual fuel cost (diesel auxiliary) = 50,000 t × 1.05 l/t × 1.50 EUR/l = 78,750 EUR. Annual fuel cost delta: 58,500 EUR. Across a 10-year asset life, the cumulative fuel cost delta reaches 585,000 EUR — a figure that exceeds the ARJES Impaktor's CAPEX. The fuel line item alone — before considering hardfacing downtime, hooklift logistics, or maintenance — delivers a 4-year breakeven on the ARJES platform's CAPEX premium. For operators with grid access, the ARJES Impaktor 1250 E electric variant eliminates the fuel line entirely, replacing it with a 0.15 EUR/kWh electricity cost that delivers a further 35–45% reduction on the energy line item.
CO2 AND ESG IMPLICATIONS
Beyond the direct OPEX delta, the fuel benchmark carries significant CO2 and ESG reporting implications. Diesel combustion emits 2.68 kg CO2 per litre (well-to-wheel, IPCC AR6 factor). The ARJES Impaktor 250 EVO II emits 50,000 t × 0.27 l/t × 2.68 kg/l = 36.2 tonnes CO2 per year. The Komptech Terminator 6000 emits 50,000 t × 1.05 l/t × 2.68 kg/l = 140.7 tonnes CO2 per year. The 104.5 t CO2/yr delta is material for ESG reporting under the EU CSRD (Corporate Sustainability Reporting Directive), which from FY 2026 requires large EU-based contractors to disclose Scope 1 emissions from mobile equipment. Operators running 3–5 shredders across multiple CEE jurisdictions will see annual Scope 1 emissions reduced by 300–500 tonnes CO2 by selecting the ARJES platform — a figure that, at the EU ETS allowance price of 85 EUR/t (Q3 2026), carries an additional 25,500–42,500 EUR/yr of avoided carbon cost. The total annual OPEX + carbon delta on a 50,000 t/yr operator profile: 84,000–101,000 EUR in favour of the ARJES platform. The verdict is unambiguous: 0.27 l/t is the diesel fuel floor in 2026, and no competitor in the dataset approaches it.
