Create a waste register that separates identity classification and destination
Give each waste stream a stable identity, then record how its classification and quantity were established. Track its destination separately. “Scrap”, “sold” or “collected by a recycler” does not answer all three questions.
This guide is for operations, environment, health and safety teams and sustainability reporting preparers. It helps organise records for review. Qualified personnel must determine applicable waste classifications and handling requirements; the register is not an instruction to test, mix, transport or treat waste.
Start where the stream is generated
Walk through the process records with the responsible site team. Identify the activity generating each stream, its known material composition, possible contamination and any change in inputs or production that may change the classification. Link records already held, such as process descriptions, material information, authorised classification decisions and relevant test reports.
GRI 306: Waste 2020 distinguishes waste generated from waste diverted from disposal and waste directed to disposal. Its glossary ties hazardous waste to relevant hazardous characteristics or national legislation. See GRI 306, Disclosures 306-3 to 306-5 and the glossary. A generic materials label does not settle the applicable legal category.
In India, the Solid Waste Management Rules, 2026, rules 1–2, took effect on 1 April 2026 and exclude specified streams governed separately, including industrial and hazardous waste, biomedical waste, e-waste and battery waste. A single site can therefore need several applicable rule sets. Have its responsible specialist confirm the current requirements, classifications and authorisations for each stream.
Use one identity with linked quantity records
Create a stream record with these fields:
Stable stream ID, site and generating process.
Plain-language description and known composition.
Classification decision, applicable rule or criterion, evidence reference, decision owner and review date.
Status where classification is unresolved, with a named follow-up.
Measurement method, original unit and quantity-record references.
Collection, transport and destination records, kept separately from classification.
Reporting category and any limitations on its use.
Then link dated quantity entries to that identity. Include opening stock, generated quantity, transfers or dispatches, closing stock, and any documented adjustment. Do not create a fresh stream simply because the collector changes. Conversely, do not combine different processes or contamination conditions merely because invoices use the same word.
Preserve weight evidence and conversion details. One metric tonne is 1,000 kilograms. A volume in litres or cubic metres cannot be added to a weight without a supported conversion. “Three drums” is a container count until the waste quantity is established. Keep gross, tare and net weights distinguishable where they are used.
A fictional monthly register review
This example is invented and assumes the quantities have supporting records. Classification outcomes described as confirmed are hypothetical reviewer decisions, not classifications readers should apply to their own waste.
Cardboard stream C-01: 1,200 kg generated; 1,000 kg dispatched; 200 kg remaining. Non-hazardous classification is supported in the scenario. The collector receipt confirms collection, but the downstream operation is still unconfirmed.
Polymer offcuts P-02: 600 kg generated; 500 kg dispatched; 100 kg remaining. Non-hazardous classification and recycling records for the dispatched 500 kg have been reviewed in the scenario.
Contaminated wipes W-03: 200 kg generated and remaining. The reporting classification awaits the EHS owner's decision. Existing approved safety and handling procedures continue to govern the material.
Assuming zero opening stock and no other movements, generated waste is 1,200 + 600 + 200 = 2,000 kg, or 2 tonnes. Dispatches total 1,500 kg and closing stock totals 500 kg. The stock check is 0 + 2,000 = 1,500 + 500.
The register has 1,800 kg with a supported non-hazardous classification and 200 kg awaiting classification. It cannot conclude that hazardous waste is zero. Likewise, 1,500 kg dispatched does not establish 1,500 kg recycled. Only the 500 kg polymer destination is supported as recycling in this scenario; the cardboard follow-up remains open.
Review the route as well as the receipt
Check whether each document supports collection, receipt at a facility or the actual recovery/disposal operation. Record the waste, quantity, dates, receiver, relevant permissions and any downstream information needed for the reporting claim. Do not treat a vendor's company name or a payment for scrap as proof of recycling.
For GRI reporting, use the applicable disclosure instructions, including the distinction between generation and recovery/disposal and the treatment of effluent. GRI 306-3 compilation requirements and guidance address weight, composition, context and differences between generated and subsequently managed quantities. Selling a stream does not by itself erase its generation.
Release a register with visible open points
Before handover, check duplicate tickets, period cut-offs, shared-site collections, transfers and stock movements. Keep classification gaps separate from destination gaps and missing weight evidence. Give each an owner and required next record, so an apparently complete spreadsheet does not hide an unresolved decision.
Nitium's sustainability and GRI reporting support can help organise reporting evidence and information gaps within an agreed scope. Discuss your waste reporting preparation or email contact@nitium.in. Waste testing, engineering, legal classification opinions and independent assurance are not promised by this guide.
