ENStarting point
A reverse logistics network should combine generation forecasts, storage capacity, material requirements and collection options. Consolidation may reduce trips, but adds waiting and handling. The decision needs to consider total cost, asset integrity, documentation and each facility's limits.
Options for connecting the network
Compare alternatives; the choice depends on the material and operation.
Map the network by stream, not just distance
For each site, record material type, quantity, physical volume, frequency, hours, access and loading conditions. An address map does not show how long a vehicle will stand idle, whether loading equipment is available or whether collection depends on asset authorisation. These factors may alter the feasibility of a short route.
Separate streams that can share a trip from those requiring specific conditions. Equipment intended for reuse, bulk materials and items presenting particular risks may have incompatible requirements. The EPA's SmartWay programme provides guidance on load utilisation and network optimisation. This supports logistics planning but does not replace analysis of the materials and rules governing the Brazilian operation. [1]
Check whether weight, volume or time is the constraint
A load can fill the vehicle before reaching its mass capacity. Hypothetical example: a usable space of 40 m³ filled with packaged material at a bulk density of 60 kg/m³ would hold 2,400 kg under those conditions. If the payload capacity were eight tonnes, the volume limit would be reached first. The calculation is illustrative and depends on the arrangement actually permitted.
Density should include the actual packaging arrangement and required spaces. Increasing it through compaction is not a universal solution: it may damage reusable assets, change the fraction or be incompatible with components present. Before changing preparation or packaging, assess integrity, safety, unloading method and the recipient's criteria. Improved load utilisation must preserve what creates value.
Compare dedicated collection, multi-stop routes and consolidation
In dedicated collection, one trip serves a defined origin and destination. On a multi-stop route, the vehicle collects scheduled batches from different sites. Consolidation at an intermediate point may allow a different transport configuration, but creates an additional facility and transfer that must be planned and suitable for the stream.
| Arrangement | When it can help | What needs to be resolved |
|---|---|---|
| Dedicated trip | Sufficient volume or time and handling constraints | Load utilisation, scheduling and return-trip cost |
| Multi-stop route | Smaller batches in compatible regions | Time windows, sequence, segregation and loading time |
| Intermediate consolidation | Dispersed generation and distant destination | Storage, handling, records and onward dispatch |
| Trigger-based collection | Variable stream with capacity to wait | Stock limits and mobilisation lead time |
No arrangement is best in every situation. The choice should be revisited when generation, destination or access conditions change.
Include added costs in the calculation
Consider four sites each making 500 kg available in the same hypothetical cycle. Four dedicated trips at R$ 900 would cost R$ 3,600 for two tonnes, or R$ 1,800 per tonne. A combined route quoted at R$ 2,200, plus R$ 400 for additional preparation, would cost R$ 2,600, or R$ 1,300 per tonne. The difference would be R$ 1,000 per cycle.
The reduction of approximately 27.8% exists only under the example's assumptions; it is neither a promise nor a market rate. Include waiting, containers, loading, unloading, relevant insurance and intermediate handling. If consolidation causes damage, lost revenue or additional storage, those effects belong in the comparison. Lower freight costs can coexist with a worse overall result.
Set collection timing using operating limits
A trigger can combine available quantity, space utilisation and the maximum time allowed by the operation. Define which condition takes priority and the lead time needed to mobilise the provider. Forecasts should account for seasonality, campaigns and exceptional collections. Collecting on the same day every time may work for a stable stream, but can cause empty trips or accumulation when generation varies.
Storage capacity must be confirmed against the facility's technical and legal conditions. Do not extend waiting solely to reduce cost per tonne where safety, quality or time restrictions apply. Planning needs an exception process: who authorises an additional trip and how the cause is documented. This information improves contract reviews.
Preserve identification at every transfer
When several batches share a vehicle, segregation and records must make their origins and destinations distinguishable. Relevant movement documents, the package list and proof of receipt must maintain this link. Partial unloading must not create administrative mixing in which only the total for the trip remains known.
During consolidation, record the receipt, any preparation, stock and dispatch of each batch or combined group. MTR/SINIR is an instrument for tracking waste movements, subject to the applicable system and classification. Confirm the requirements for each stage; an internal logistics spreadsheet does not replace relevant environmental or tax records. [2]
Control delays without losing sight of their causes
Define the timeline events: complete request, acceptance, collection, receipt and documentary closure. A request without an inventory or authorisation is not in the same state as a ready load. Record when the operation became available and the reason for every rescheduling. This prevents the indicator from attributing to the carrier a wait caused by an unresolved internal issue.
Track waiting hours, unsuccessful trips, package discrepancies and damage. Alongside the average, examine extreme cases and open issues. A network may show an acceptable average lead time while one site remains unserved for a long period. Use these data to review frequency, time windows and responsibility for scheduling information.
Reassess the network based on actual results
Compare forecasts with the mass actually collected, load utilisation and cost per stream. Separate the effect of a change in distance from that of a change in material profile. Do not rely solely on cost per tonne for assets whose value depends on each unit's integrity. In those cases, damage and the proportion of equipment accepted for reuse help interpret the result.
Reductions in kilometres or trips should not automatically be converted into avoided emissions without an appropriate methodology and operational data. The reverse logistics service can connect planning, operators and monitoring across sites. A properly designed network delivers the stream under the agreed conditions and makes visible the cost of maintaining that consistency.
