Dutch Glycerin Factory Saved €1 Million a Year by Illegally Dumping Toxic Waste Salt Near the Belgian Border
Groningen, Saturday, 6 June 2026.
A Groningen glycerin factory disguised toxic waste salt as a soil improver, avoiding disposal costs while contaminating farmland near the Belgian-Dutch border. Criminal investigations are now underway.
A Factory, a Fraudster, and a Toxic Scheme
At the heart of this scandal is Dutch Glycerin Refinery (DGR), a glycerin factory located in Farmsum, on the Chemie Park Delfzijl in the province of Groningen, the Netherlands [1][3]. DGR is a subsidiary of the Musim Mas Group, a palm oil production and processing conglomerate that employs some 37,000 people worldwide, making it one of the largest players in the field of palm oil production and the processing of palm oil derivatives [3]. Despite that corporate scale and international reach, it is alleged that DGR pursued a strikingly low-tech and damaging scheme to avoid the costs of properly disposing of a troublesome by-product of its industrial process: waste salt [1][3].
What the Regulators Found — and When
A damning investigation report compiled by the Omgevingsdienst Groningen (Groningen Environmental Agency) reportedly left little of DGR’s own account of events intact [3]. According to FTM’s reporting on the document, the agency concluded that ‘the company is in fact disposing of a waste substance but presents it as a by-product, possibly to escape the waste materials regime and to save costs’ [3]. The agency further noted that DGR had acknowledged that demand for road salt had dried up and that it had no visibility into what intermediary traders were doing with the material — a critical admission that, combined with the fact that DGR was paying for the removal of the substance, reinforced the regulator’s conclusion that the material should be classified as waste [3].
Criminal Investigations Multiply Across Borders
As of the time of reporting on 6 June 2026, multiple criminal and administrative investigations are underway across at least three countries. In the Netherlands, the Functioneel Parket of the Openbaar Ministerie (Public Prosecution Service’s Functional Department, which specialises in financial and environmental crime) has launched a criminal investigation into the illegal export of waste [1][2]. The ILT, which had previously held back from exercising its administrative enforcement and supervisory powers while awaiting clearance to proceed alongside the criminal investigation, has since received that green light and has now resumed its administrative duties [2]. The municipality of Eemsdelta, within whose jurisdiction DGR’s Farmsum facility falls, has confirmed it is investigating what follow-up steps and measures are appropriate and proportionate following the Omgevingsdienst’s report, and stated it cannot yet pre-empt any decision-making [2].
The Broader Stakes for Dutch Industry and Environmental Oversight
The DGR case is a stark illustration of the enforcement gaps that can emerge when industrial waste regulation relies heavily on self-classification by producers. The core of DGR’s alleged scheme — labelling a waste product as a useful by-product to escape regulatory scrutiny and disposal costs — is not unique to the glycerin sector [GPT]. It reflects a structural vulnerability in waste regulation where the burden of accurate classification falls on the generating company, and where monitoring capacity may be insufficient to catch misclassification before harm occurs [GPT]. The Omgevingsdienst Groningen’s investigation report, which FTM states it has obtained, provides a detailed rebuttal of DGR’s characterisation of the salt as a legitimate soil improver [3].
