SmartTrap + GREX-1000 — Preliminary Cost Basis
Concept Revision C · November 7, 2026
Planning allowances in USD for scope review, pending supplier quotations. Equipment throughput and utilities remain unselected.
Revision C: facility and reuse budget status
The design now assumes a permanent facility in AmeriPro's available building, with an existing separator and screw press evaluated for reuse. The prior compact-package allowances below are retained only as a historical comparison; they are not the revised facility budget. No revised capital total is established.
| Revised scope | Budget treatment |
|---|---|
| Existing custom screen separator and PJDL-302 press | Owner-supplied candidates for screening / sludge dewatering; trials, condition assessment, controls and installation still to be quoted |
| Additional oil / water recovery stage | Separate unselected duty; existing solid-liquid machines do not establish that this purchase is avoided |
| Available building | No building purchase assumed; survey and any fit-out remain unpriced |
| Receiving, process and storage tanks | Resize after feed schedule, trials and holding requirements |
| Piping, supports, access and installation | Replace single-skid integration assumption with site-specific scope |
| Electrical, heat, ventilation and containment | Survey existing capacity; price necessary upgrades |
| Laboratory work and commissioning | Include equipment trials, full phase balance and acceptance testing |
Do not subtract the previous $75,000 separator allowance as guaranteed savings. The equipment guide identifies the existing separator as a screen / screw solid-liquid machine, not the previously envisaged oil-recovery package. The earlier scope did not separately price the PJDL-302 press. See the equipment guide and open questions. Compare a reuse / refurbishment case with a new-equipment case on equivalent capacity and product requirements.
Historical Revision A prototype and process allowances
| Scope | Placeholder allowance |
|---|---|
| One SmartTrap development prototype: body, mechanism, sensors, collector and initial integration | $12,000 |
| Prototype contingency, 20% | $2,400 |
| SmartTrap prototype study total | $14,400 |
This is not a retail price or a certified installation cost. Kitchen plumbing changes, formal performance / certification programs, repeated prototype iterations and fleet manufacture require separate scope.
| Historical compact GREX-1000 package | Placeholder allowance |
|---|---|
| Receiving / feed handling | $25,000 |
| Controlled heating / conditioning provision | $25,000 |
| Screening | $15,000 |
| Mechanical separation package | $75,000 |
| Filtration / polishing | $18,000 |
| Controls / electrical | $25,000 |
| Skid / integration hardware | $20,000 |
| Product and residual holding allowance | $20,000 |
| Process development / integration / initial acceptance allowance | $35,000 |
| GREX base allowance | $258,000 |
| Contingency, 20% | $51,600 |
| GREX concept study total | $309,600 |
| Historical combined prototype + plant budget | $324,000 |
These allowances do not establish that the pictured arrangement can be built at the stated price. Trials can change or eliminate packages.
Batch contribution model
The interactive page uses a hypothetical $0.45/kg price for buyer-accepted oil-rich product, $100/batch collection cost not already covered by pumping charges, $120/batch processing allocation and $0.08/kg handling for aqueous residual plus wet cake. All are editable placeholders. No local market, buyer quote, tipping fee or disposal quote is represented.
The model books zero sales revenue while qualification is pending. If buyer acceptance is assumed, revenue equals modeled oil-rich product mass times entered price. Contribution subtracts acquisition / collection, processing and residual handling. The default scenario produces a negative contribution even with assumed sales.
Avoided disposal credit. Most GREX feed would come from AmeriPro's own grease-trap pumping, which customers already pay for. Trap waste processed at GREX no longer goes to an outside receiving facility, so the tipping fee AmeriPro pays today becomes a credit to each batch. The calculator has an input for this credit (default $0, since the fee is AmeriPro-specific) and reports the credit needed to break even. At the defaults, that is about $289.54 per 1,000 kg batch on hold, or $230.69 with assumed product sales.
Fixed overhead, capital recovery, financing, taxes, storage, product rejection / disposal, depreciation, residual classification changes, buyer testing and any downstream fuel conversion are excluded. Holding product can still incur additional costs not calculated. No “free disposal,” avoided pumping or environmental credit is booked automatically.
Required commercial evidence
Obtain source-separated feed analyses, actual collection and handling costs, representative separator / conditioning trials, prospective buyer specifications and written pricing, and receiving costs for each residual. Include storage / logistics and rejected batches. Verify all equipment and utility scopes before selecting a site or assigning a project budget.
