THE STUDENT WASTE BANK
FROM DEPOSIT TO RECORD
A QR code connects a deposit to a student account. An operator records the material type with its weight and condition during collection.
Digital records help schools follow participation and manage points. Staff still inspect the material and confirm that rewards reach students.
SCHOOL SYSTEMS RESEARCH
Lumiere research compares 231 capacity configurations across 10,000 weekly scenarios. The leading hybrid combines 20% shared capacity with 25% reserve and a 2.25% simulated failure rate. The dashboard shows the reported results with the calculations below.
WHAT THE WASTE BANK RECORDS
Identify a student account through its personal QR code.
Record each material weight with its condition and collection date.
Connect accepted deposits with the student’s points record.
Track reward requests through handover at school.
Give school staff and operators access to the tools they need.
THE MATHEMATICS OF CAPACITY
Weekly processable collection depends on participation and sorting quality. The material balance assigns every kilogram to treatment or untreated collection. Capacity limits change with facility availability. Reserve and the shared capacity fraction are separate design choices.
FROM RECORDS TO DECISIONS
Measure collection by material and date. Keep rejected mass separate from accepted mass.
Use comparable school weeks when estimating mean collection and variation.
Account for shared fluctuations when several schools have high collection at once.
Keep the organic-waste research boundary separate from recyclable deposits and product counts.
OPTIMIZATION UNDER UNCERTAINTY
Choose capacity before weekly collection is known. Then allocate each week’s material within the available capacity. The model compares weekly expenditure with a penalty for untreated mass and requires the probability of any untreated collection to stay below 10%.
