Matching materials by specification, not just category.

Connecting supply and demand looks simple: someone has material and someone needs it. In practice, most connections fail on details a category does not capture: a specification that does not match, an insufficient volume, an unviable location, a process requirement.

A bale of green PET, a PCB and an aluminum offcut should not go to the same type of market, even if all three are “waste”.

The usual alternative is a directory: a list of buyers by category. It solves the problem of knowing who exists, but not of knowing who fits, and it forces whoever uses it to rule options out by hand. “Here are three phone numbers” moves the work to the person who suffers it most.

An open marketplace does not solve it either: publishing a material does not say who it is useful for. Trace Match is not a directory or an open marketplace; it is a compatibility assessment.

If the material is described with a specification and the demand is described with its requirements, compatibility can be evaluated dimension by dimension and explained. Each dimension can rule an option out or make it more attractive: material, specification, volume, location, logistics, buyer requirements, demand, commercial conditions and possible netback.

The assessment depends on the information available. Where a data point is missing, it is not invented: it is marked as to be confirmed.

A material described as “plastic” could match dozens of buyers. The same material described by its resin, form, contamination level and monthly volume matches very few, and those few are the ones that matter. The matrix above shows the idea: one demand can fit on material and volume and fail on specification; another can fit on everything that is known and have two things to be confirmed.

Illustrative example. There are no real buyers or company names on this page.

There is no good compatibility without a good specification. If the material is described with a label, any assessment will be as imprecise as the label. That is why Material Specification is the input to Trace Match, and not the other way around.

Trace Match does not promise a buyer or a commercial result. Compatibility by specification, location and conditions is an assessment under development, and each match should be explainable with the dimensions above and show what information was missing.

The most useful matches are not the highest-scoring ones, but the ones that can be explained. Ruling out well is as important as finding: location and volume tend to eliminate more options than it seems, and ruling them out early saves time for the parties involved.

Better input specifications, more market context and more outcomes that teach which matches work, which is the subject of Outcome Learning.
