Why become a VETSTRIJDER?

The problem

Amsterdam is increasingly at risk due to the sheer volume of FOG that is entering the sewer system. Blockages are affecting daily life within the city center and the surrounding environment.

To provide a long-term solution to the growing threat of fatbergs, we must significantly reduce the amount of fat, oil, and grease that escapes down the sink.

The costs for maintaining the sewer network continue to increase every year. The more we need to show up for interventions, the more nuisance for the Amsterdamer. Preventing FOG to enter the sewers means you’re tackling the problem at source. That’s why we endorse Vetstrijder

The cost

 In 2016, the maintenance costs of the sewerage system in 2016 amounted to no less than 42.6 million euros. The annual costs for the management of the sewerage system are estimated to increase by € 1.2 million to € 43.8 million in 2021.

What’s the answer?

Employing some simple rules and keeping a well maintained grease trap will prevent fatbergs bubbling up through outlets around your business or into rivers and causing environmental damage.

Grease interceptor are regulated by law to ensure that each food service entrepreneur does their part to protect their business and Amsterdam.

Maintaining or emptying your grease interceptor on time will ensure that you avoid unnecessary costs due to sewer disruptions and blockages.

Other preventive measures include always dry wiping meal residue from the plates not using many detergents. Overdose can cause the grease to solidify further down the sewer.

The trend to eat more sustainably continues unabated. Consumers, but also hospitality entrepreneurs, have understood this very well. We support Vetstrijder as sustainability must also continue behind the scenes. KHN is committed to sustainable entrepreneurship and advises hospitality entrepreneurs on how to prevent FOG in wastewater. Vetstrijder is a nice addition to that with a hospitality-friendly approach

What is a grease interceptor

A grease interceptor is a container between the drain and the public sewer where the wastewater flow is being slowed down. It allows solid particles to sink, and FOG to rise to the surface. The remaining water flows through to the sewer system.

The two most important aspects for a properly working grease interceptor: a suitable size and frequent maintenance. The standard rule says the grease interceptor must be inspected, emptied and cleaned at least once a month.

In the case of an inspection by the enforcement department, inspectors pays attention to the maintenance cycle in particular as wastewater samples can’t be taken during inspection because fat concentration can fluctuate considerably.

What happens to collected FOG?

The removal of the (solidified) fat from the grease interceptor must be carried out by a recognized service provider. When cleaning the interceptor, a mix of fat, water and sludge is being pumped out and removed.

Service providers sustainable treat the fat and convert it into various useful products including environmentally friendly biodiesel.

The difference between yellow or white fat, and brown fat

Fat in wastewater mainly comes from pan fat, or cooking fat. We try to recover this so-called brown fat with the fat separator as a raw material for biodiesel.

Yellow or white fat from the frying machine is collected in a barrel. It is relatively pure and requires fewer processes to be used as a raw material for biodiesel. Nowadays, fat collectors pay for used frying fat. Sometimes it is possible to have the same service provider carry out the inspection and fat removal at the same time. 

How you can do your part for Amsterdam

Recent reports have found that many restaurants inadvertently let FOG from their kitchen enter the sewer system. To help our sewers get back on top, you can join fellow hospitality entrepreneurs in the fight against underground fat.
