The pilot — GreCoM

Read by people, not only by software

Companies in the Netherlands, in four sectors to start with. Every entry and every candidate pairing is read by a named reviewer before anything is shown to anyone.

It also means there is nothing to show you in the way of participant numbers, tonnages or case studies: there are none yet, and GreCoM publishes no figure it cannot stand behind. Being early in a reviewed system means your entry gets more attention, not less.

Who can join: Companies in the Dutch trade register. Elsewhere: a waiting list, with no obligation.
Cost: The pilot is free of charge. A fee model for after the pilot will be published before it applies.
Entry review: Target 3 working days; a second named reviewer for the first fifty entries.
Match review: Target 5 working days.
Disclosure review: Target 2 working days; an unanswered request expires after 14 days.
Availability: Confirmed quarterly; paused after one missed cycle, archived after two.
Language: English and Dutch.

The first four sectors

Where the pilot starts.

Four sectors, chosen because each has streams that recur, a receiving side that already exists, and enough companies within a short drive of one another for geography to count. If your material sits outside them, you can still register — say so, and it tells us where to look next.

Port logistics and warehousing

Pallets, stretch and shrink film, strapping, big bags, drums and crates — the packaging a terminal or a distribution centre removes before the goods move on. High volume, highly repetitive, and usually clean enough to have a second use rather than a disposal cost.

Construction and demolition

Rubble, concrete, sorted aggregate, soil, timber, insulation and mixed fractions from a site with a known end date. Here the distance between two companies often decides whether a stream has any value at all, so proximity carries real weight in the assessment.

Agriculture and greenhouse horticulture

Agricultural and greenhouse film, substrate, crop residue, trays and twine — seasonal, predictable to the week, and most often a collection cost rather than a sale. Where the money runs that way, an introduction is worth the disposal bill it removes.

Small and medium manufacturing

Steel, stainless and aluminium offcuts, turnings and swarf, polymer purgings, sprues and regrind, textile and composite trim. Small quantities one at a time, and a stream worth describing properly precisely because nobody is collecting it in bulk.

Questions

The ones worth asking before you join.

Who is already on the platform?

The first companies are joining now. We do not publish participant numbers we do not have, and a platform that shows you a figure before it has one is telling you something about how it will treat your data later.

Do you test the material?

No. GreCoM reads what a producer declares — the measured properties, the method and date of each measurement, and any supporting documents — checks it for completeness and plausibility, and marks the entry Data reviewed. It does not sample, analyse, certify or warrant anything. Your own acceptance testing remains yours, as with any new source.

What does it cost?

The pilot is free of charge. A fee model for after the pilot will be published before it applies.

The platform asks for no payment and holds no payment details. Taking part is governed by the Terms of use, which you can read before you register.

Who inside GreCoM sees my data, and what stops them misusing it?

GreCoM’s reviewers and administrators see your identity and your entry, because checking a company and reading a submission are human tasks. Every reveal of an identity and every opened document is written to a log with the staff member’s name and their stated reason, and that log cannot be altered afterwards. Internal notes live in a separate database role that the participant-facing application cannot read. The detail is here.

Is this legal, and what about my own permits?

GreCoM takes no ownership or possession of any material, arranges no transport, and is not a party to any transaction: it operates as an information-society service that introduces two companies.

Your own obligations are unchanged by using GreCoM: permits, classification, end-of-waste status where it applies, and transport documentation stay between you and your counterparty.

We are registered outside the Netherlands. Can we join?

Not yet. Registration is limited to companies in the Dutch trade register and anyone else is placed on a waiting list. You will be told when that changes.

What if nothing matches, and how long does everything take?

Then you will be told exactly that, and your entry stays live and is compared against every new one. Review of an entry has a target of three working days, a pairing five, and a disclosure request two; an unanswered disclosure request expires after fourteen days. GreCoM will not show you a weak pairing to avoid showing you nothing.

A value I need is not in the lists. What then?

Tell us. The reference lists follow the companies taking part, and a missing category, property or band is exactly the kind of thing the pilot is for. The interface is in English and Dutch; if a term reads wrong in either, telling us helps too.

Joining the pilot.

Register, and GreCoM will check the company and come back to you. If your material category is not among the first four sectors, say so — it tells us where to look next.
