Oldenburger Fleischmehlfabrik (Friesoythe-Kampe)
Oldenburger Fleischmehlfabrik GmbH (OFK), HRB 150523, Amtsgericht Oldenburg
Says it sells
The plant's product page says its Category 1 fat goes on to biodiesel and its Category 2 fat to oleochemistry and biodiesel, and asks anyone interested in buying to get in touch. It runs no biodiesel plant of its own. Source: OFK product page, read .
Ask on the first call: 3 questions
- How much Category 1 and Category 2 fat do you produce a year, and is any volume free for a new buyer?
- Is any of the fat fired in your own boiler house, and what share?
- Can a lot be loaded at Friesoythe-Kampe, and under which Incoterm?

Where the sellers are
A source is one company's supply of one feedstock in one country: who sells it, from which site, and the dated public evidence behind it.

Counts are our own reviewed sources, not certificate register counts. A dot is a market we have not opened yet, not a country without sellers. thin marks a market shipped with 4 sources under our thin-market rule: the usual minimum is 5, and at least 2 of the 4 must state a sale on their own site.
Need a country we have not opened yet? Tell us which.
Selling used cooking oil, animal fat or glycerine? Tell us where it loads and how much: the seller form is on the used cooking oil, animal fats and glycerine pages.
How we verify
Every market is checked before it opens, and its certificates every week after
A gate set before the research
Each market opens only if it passes thresholds we wrote down before the research began, so the result cannot be bent to fit.
An independent second pass
An independent second pass, separate from the research, rereads every quote behind a sale statement, site and certificate before a market goes live, and its notes are kept with the market.
Certificates every week
For the 527 sources whose ISCC, REDcert or KZR INiG certificate ID we hold, we recheck the issuer's public list every week. The ISCC, REDcert and KZR INiG lists were last read on 2026-10-26. Where a source holds several, the recheck follows the one that lapses first. A lapsed certificate is flagged on its record.
Thin markets say so
1 of 36 markets shipped with 4 sources under our thin-market rule, one below the usual minimum. It carries a thin label, here and in the app.
Failed markets stay on file
When a country fails its gate, we keep the finding as a negative result instead of filling the gap with weak leads.
Eligibility by destination
Check how the material counts where you sell
Name the market you sell into, and your Sourcing Brief shows how that market counts the material toward its biofuel targets. We hold reviewed rules for EU Annex IX, Germany and the UK RTFO (all four feedstocks), and the Netherlands (Category 3 fat only so far). Each rule shows the official text it comes from and the day we read it.
Germany · Category 3 animal fat
Biofuels from Category 3 animal fat count toward the GHG quota up to a 0.3% energy share per obligation year; above that, the fossil base value applies.
Inside OxyLens
From the map to the evidence behind a source
Find sellers
Narrow by country and feedstock. Each source card names the operator, its role and its sites, with the public records behind each claim.
Qualify the evidence
Read what a source states, what we infer and what nobody has established yet, each marked separately and dated.
Compare to your requirement
A Sourcing Brief holds your material and commercial need. Route Fit shows which sources match it and which questions are still open, without ranking suppliers.
Prepare the call
Call Sheets carry the open grade, volume, site and loading questions into your first conversation with the seller.
Keep your answers private
Your marks and the seller's answers stay in your own workspace, apart from the public evidence and from other customers.
Limits
What a record does not tell you, and what else you will ask
A record shows who the seller is, where the site is, what its certificate covers and what the company says in public about selling. It cannot tell you today's stock, the price, the quality of a given lot or whether the seller will take on a new buyer. Those answers come from your first call, and each record lists the questions to ask. Coverage differs by country and is never a full census.
Contacts are the company's published business contact routes or the address in an official record. Sole traders and private persons are shown by role and town only, and their records open only in Full. Any company can ask us to correct or remove its record: the form is on the used cooking oil, animal fats and glycerine pages.
Every sale statement and certificate check carries the date we read it. Certificates with an ID on record are rechecked every week; other facts are re-read when their market is reviewed, so the date on the record is the one to trust.
