Waste Stream Register

This register is the master list of what a site produces; it is not where a single collection gets recorded. Using it to document one shipment, or skipping it because the transfer record already names the waste, both produce gaps a reconciliation will catch.

RCRA and its provincial equivalents require waste to be identified and classified at the point of generation, but neither prescribes a register format. The register earns its defensibility from consistent classification and a documented review trigger, not from its layout.

The duty to classify waste correctly is close to universal; what differs is which classification scheme applies and how record-keeping is enforced.

Most registers list what is easy to see. The parts that make the register useful are the ones nobody prompts for.

The register almost always exists. The findings concern whether every stream the site actually produces is on it, and whether the ones that are on it are classified against what the process actually produces.

A manufacturing site added a new coating line eighteen months after the waste stream register was last built. The waste from the old line had been solvent-based and classified hazardous; the new line used a water-based formulation and someone updated the stream's description but left the classification and disposal route unchanged, because the line looked similar enough to not warrant a fresh determination.

A waste audit six months later found the opposite problem: the register still listed the stream as hazardous when the new process, correctly assessed, was not, and the site had been paying for hazardous disposal and documentation it did not need for a year. The register had never lied, but nobody had re-run the classification when the process changed, and the stated review date had not yet come around to catch it.

The register is a list. What fails is keeping it aligned with what the site actually produces, and connecting a changed process to a review before an audit finds the gap.

KnowEnviro

Holds the waste stream register against the site's processes and contractors, flags streams whose classification has not been revisited since a related change, and routes the review to the environmental lead.

KnowComply

Checks the register against contractor audits and reconciliation reports, and surfaces streams whose disposal route or contractor no longer matches what was last verified.

KnowTrain

Connects a stream's classification to the segregation training the people handling it depend on, so a category change produces a training update rather than an assumption.

Ella

Watches process, material and contractor changes for events that should invalidate a stream's classification, and raises the review rather than waiting for the stated review date.

Waste stream

A distinct category of waste arising from a specific process or source, with its own classification, quantity and disposal route.

Waste code

The classification code from the applicable waste catalogue that determines handling, transport and disposal requirements.

Waste hierarchy

The ranked priority order for managing waste: prevention, reuse, recycling, recovery, then disposal, with disposal as the least preferred outcome.

Animal by-product category

The category, 1, 2 or 3, assigned to animal by-product material under the applicable regulation, which fixes whether it must be incinerated, may be rendered, or may go to feed or digestion.

Diversion from landfill

The proportion of waste sent to a route other than landfill, used as a headline indicator of how far up the hierarchy a site's disposal routes actually sit.
