Start with measured waste, not a brochure capacity
Measure normal and high-load days separately. For restaurants, hotels and institutional kitchens, large events can cause short peaks. A 200 kg/day option may improve headroom when peak loading exceeds the practical operating plan for 100 kg/day, but a larger machine also has acquisition, space and utility implications.
- Weigh seven representative operating days, including the busiest day.
- Exclude packaging, plastics, glass and non-accepted streams before sizing.
- Ask the OEM whether daily nameplate rating assumes a single batch, multiple batches or a specific feed.
Compare only equivalent 100 and 200 kg specifications
Do not mix figures from different series or manufacturers as if every 100 kg model is identical.
| Criterion | 100 kg/day model | 200 kg/day model |
|---|---|---|
| Rated daily incoming feed | Up to 100 kg/day per specified conditions | Up to 200 kg/day per specified conditions |
| Best decision cue | Measured peaks sustainably fit the rating | Measured peak plus reserve exceeds practical 100 kg plan |
| Connected load | Ask for exact published kW and duty cycle | Ask for exact published kW and duty cycle |
| Space & access | Check body footprint, doorway and service clearance | Recheck larger body, forklift/route and service clearance |
| Post-processing | Segregation, output storage and curing still needed | Same process requirements at higher material volume |
| Buying risk | Frequent overload / little reserve | Oversizing / idle asset and higher capex |
A simple 100 versus 200 selection scenario
Example only: if normal waste is 85 kg/day but busy-day waste reaches 135 kg/day, choosing solely from the normal number is risky. The 100 kg unit cannot cover a 135 kg incoming day at nameplate rate; evaluate 200 kg or scheduling/storage options with the manufacturer. By contrast, a true peak of 70 kg/day may not warrant 200 kg.
This is a selection example, not a recommendation for a particular customer site.
Electrical supply and installation are not an afterthought
Ask for model-specific phase requirement, MCB/protection, connected load, cable run, earthing, ventilation and discharge access. Connected kW is not the same as actual kWh per day. An expanded capacity can also increase sorting, staff and curing-space requirements.
- Compare total installation cost and warranties, not only machine base price.
- Verify service availability and operator handover commitments.
- Request GA drawings and written utilities before the order.
Final PO checklist
Before confirming, document measured waste records, acceptable feedstock, exact machine model, construction material, shredding arrangement, controls, power, curing, included training, testing protocol, dispatch and unloading responsibility.
