ENStarting point
A business tender should allow participants to price the same scope, present their conditions and demonstrate execution capacity. Selection combines mandatory requirements and comparative criteria. This article's guide is intended for private contracting; public procurement and asset disposals follow their own procedures.
Choose the contracting model before approaching the market
Selling scrap, contracting treatment or disposal, and managing a set of flows are not the same transaction. In a sale, the buyer pays for the material under defined conditions. In a service, the generator pays for activities and evidence. In an integrated contract, revenue and expenses may coexist, with responsibilities distributed among the parties.
Define the main subject and interfaces. If the company wants to sell metals and contract treatment for a fraction with no value, state whether it will accept separate proposals or only a complete solution. ISO 20400 provides guidance on integrating sustainability into procurement decisions. Its scope offers a management reference; the criteria and weights presented here are organisational suggestions, not requirements taken from the standard. [1]
Build a usable information package
Include inventory, location, known composition, condition, representative images, measured or estimated quantities and a schedule. Distinguish available stock from future forecasts. A history of generation is not a supply commitment, and that distinction must appear in the enquiry. Where there is material uncertainty, describe how interested parties may inspect or sample the material.
State access, hours, loading resources, containers, weighing and collection restrictions. For electronics, add asset ownership status, data media, locks and reuse limits. The package should have a version, date and owner. If information changes, distribute the update to affected participants before comparing proposals; an old spreadsheet may produce an apparently better price because it omits part of the service.
Divide batches according to market capacity
Overly broad batches may exclude specialists who could serve one fraction well. Excessively small batches may multiply collections, contracts and reconciliations. Compare these alternatives by total cost and internal management capacity. The division should also preserve the material's identification and technical condition, avoiding mixtures that destroy recovery opportunities.
One possible structure separates reusable assets, homogeneous materials with a market and waste requiring treatment. Another organises the tender by region or facility. The choice depends on volumes, interfaces and risk. Where an integrator may subcontract stages, ask it to identify each service provider's role and how it will maintain the link between origin and downstream destinations.
Separate qualification from scoring
Essential requirements should act as a condition for participation or contracting. A high commercial score does not compensate for the inability to perform a necessary activity. Check the scope of relevant authorisations, the facility's capacity, data controls and flow requirements with the technical leads. Then compare the alternatives that meet those conditions.
Model for organising criteria

Comparison on the same basis
Write down what the scores mean. “Good service” is subjective; a response procedure with an owner and contractual deadline can be examined.
Make the scoring explain the decision
A hypothetical example: among eligible bidders, the company assigns weights of 40% to operations, 25% to records and 35% to economic terms, using scores from zero to ten. Proposal A receives 8, 9 and 7: its weighted score is 7.90. Proposal B receives 9, 7 and 8: it achieves 8.15. The weights illustrate the method and do not represent a universal preference.
A small difference requires examination of the evidence behind each score. Perform a sensitivity analysis of the weights and identify whether the ranking depends on a poorly supported assessment. If the economic criterion uses contribution per batch, compare costs and revenue within the same scope. Scoring helps document the reasoning; it does not remove the need to resolve material uncertainties before deciding.
Use clarifications and a pilot to reduce uncertainty
Consolidate recurring questions into a clarification round. Answers on composition, responsibility for rejected loads and the weighing basis should reach participants on equivalent terms. If there is a technical visit, document what was presented and which access limitations affected inspection. Avoid allowing a verbal promise to become an essential condition in just one proposal.
When uncertainty concerns execution, a clearly bounded pilot may be more useful than another commercial presentation. Define batches, quantities, evidence, success criteria and responsibility for expenses. The pilot needs to test what could reverse the decision: receipt, output quality, close-out time or yield. A demonstration using selected material should be identified as such and should not replace validation of the recurring flow.
Turn the winning proposal into an operational arrangement
After selection, consolidate scope, price, validity, revision, service levels and exception handling in the appropriate contract. Those responsible for procurement, operations, environmental matters, tax and data need to know the points assigned to them. Commercial approval does not automatically resolve asset release or qualification to receive a particular material.
Hold a mobilisation meeting with a collection simulated on paper: who requests it, what identification accompanies the batch, who issues each record, how the destination confirms receipt and who accepts close-out. This exercise reveals gaps before the first truck. Link the final proposal to the annexes used in the tender so commitments can be located later.
Learn from the contract before the next tender
Compare contracted and actual results by flow: cost, revenue, deviations, timing and documentation quality. Record composition and volume changes that explain legitimate differences. Do not assess the provider against an assumption that the operation itself no longer meets, or accept revisions without evidence. Historical data should distinguish a change in scenario from an execution failure.
The result informs the next market enquiry and helps identify what needs revision in the scope. The economic comparison of pathways explores the calculation in more depth, while materials brokerage can connect supply, receiving conditions and a counterparty. A tender becomes more useful when it produces an agreement the operation can fulfil and verify.
