Is your blue grease drum with used cooking oil full? Rotie will come and collect in an instant and arrange for the sustainable processing thereof. Rotie has been specialised in the collection of used cooking oils at hotel and catering establishments, industries, clubs and pubs for over 60 years. Today, Rotie collects used cooking oils in the Netherlands, Belgium and parts of Germany at more than 35,000 addresses. Thanks to our nationwide coverage and local service, we can come and collect instantly, at any time.

The used cooking oils are processed into second-generation biodiesel, in cooperation with our sister company Biodiesel Amsterdam. The upcycling of our customers’ used cooking oils into biofuel means that the use of fossil fuels is reduced. Together with our customers, we offer a unique solution for the reduction of greenhouse gas emissions.

THE PROCESS

Rotie works for a wide variety of companies. Our customers vary from large companies in the food industry to small hotel and catering establishments. Used cooking oils are collected at more than 35,000 addresses. Rotie collects the used cooking oils and fats in accordance with current legislation.

 

Rotie ensures that your used cooking oils and organic industrial waste are collected and recycled into second-generation energy, in accordance with a sustainable and environmentally friendly process. When collecting the organic residual waste, Rotie minimises the number of trips it makes.

 

Recycling natural raw materials reduces the use of fossil fuels. The use of green energy offers a unique and effective solution for the reduction of greenhouse gas emissions.

Used cooking oils and fats that have been collected arrive in the modern processing plant. The drums with used cooking oils are then put on a conveyor belt. After the drums with used cooking oils have been sorted, they are emptied into the melting pit. The used cooking oils and fats are heated, creating a homogeneous mass.

 

After the drums with used cooking oils have been emptied, they are cleaned industrially. Rotie collects rain water on the roof of its processing plant. This rain water is used for the hygienic cleaning. The cooking oil drums are dried immediately after having been cleaned. This enables the drivers of Rotie to be on their way in their trucks with clean packaging, practically without any delay.

A treatment process involving filtration and sedimentation is used to transfer the used cooking oils to the biodiesel plant of sister company Biodiesel Amsterdam. At the biodiesel plant, the used cooking oils are converted into second-generation biodiesel, in accordance with the European EN14214 standard of the highest quality.

 

The produced biodiesel is subsequently stored in a tank, after which it is ready for shipping. Each year, 125 million litres of biodiesel are produced from used cooking oils collected by Rotie.

 

Biodiesel is not a burden on the environment and has a favourable effect on the performance of the engine. Compared to fossil fuels, biodiesel reduces greenhouse gas emissions by more than 85%.

 

The biodiesel that has been produced is mixed into the diesel you put in your car every day. Recycling natural raw materials reduces the use of fossil fuels. The use of green energy offers a unique and effective solution for the reduction of greenhouse gas emissions.

Unfortunately, used cooking oils are often still flushed into the sewer system. This is bad for the environment, causes blockages and costs a lot of taxpayer’s money each year.

 

Because not everyone is aware yet of the fact that domestic, used cooking oils should not be flushed or deposited in the grey bin, Rotie has started the “VET GOED – wat je ermee doet” campaign.

 

You can now easily deposit used cooking oils at one of the 1250 collection points. This way you make a contribution to a better environment and the used cooking oils are given a new lease of life.

“I’ve come to know Rotie as a highly professional company with reliable staff. In addition, it’s extremely important for Loetje Group that our waste stream is processed in a responsible way and as environmentally friendly as possible. All in all, Rotie and Loetje Group are partners that enhance and complement each other.”
