The OckoBOX – environmentally friendly disposal of household frying oil

Frying oil can be reused up to eight times in the private kitchen before it should be replaced. But it is still not waste. It is full of energy. When properly processed, it can be used as an environmentally friendly raw material for the production of biodiesel. You can support this process:

As a consumer, you can dispose of your old frying fat and cooking oil free of charge in our OckoBOX, and we can extract green energy from it. From the pot to the tank - here you will learn how to properly dispose of old cooking fat and oil and what can be created from it in the green material cycle.

         

Old fat should not be flushed down the toilet or poured into the sink! 

How frying oil and cooking fats should be properly disposed of

Until now, households had no choice but to dispose of their old fat via the residual waste bin. However, its dormant energy potential remains completely untapped - disposal instead of recycling. But if you want your old cooking fat from your kitchen to be reused in a meaningful way and thereby do something good for the environment, then disposing it in the OckoBox is the right solution for you. Where can you find it? Right around the corner - at your local supermarket and at your recycling center.

You want to protect the environment and support the green material cycle, where old cooking fat is turned into environmentally friendly biodiesel? Here you can see where you can find the nearest OckoBox, where you can dispose of your old household frying oil sustainably. By clicking on the respective OckoBox head, you will find the address. 

How old fat should not be disposed of

You must never pour old fat from the household into the toilet or sink. Because in doing so, fat residue remains in the pipes, hardens, and clogs them. Some fats are even particularly treacherous for drainage pipes. For example, coconut oil: It solidifies again when it cools down and therefore becomes stubbornly stuck.

If hair, food residues, or other foreign substances also adhere to it, it can lead to serious blockages and foul odors. In the same way, dumped fat causes damage in the public sewer system. Furthermore, there is a risk of contaminating groundwater. Finally, in the wastewater treatment plant, fat generally hinders the cleaning of the wastewater.

In short, fats and oils in the drain harm the entire water cycle.
However, old cooking fat should not be disposed of in the bio bin or compost either. Unlike vegetables and fruits, fats and oils do not decompose. Instead, they leave behind a greasy film, cause unpleasant odors, and can even attract pests.

How old fat is recycled in an environmentally friendly way

Through our clean recycling of old fat and cooking oil, there is no burden on the sewer system and groundwater, but rather the environment is sustainably protected. With our specialized process, we prepare the frying oil from your kitchen in such a way that it can be used to produce biodiesel. This fuel is CO2-neutral and helps protect the climate. It also reduces dependence on oil imports. Biodiesel from cooking fats is a standardized biofuel that is blended with regular diesel at a legally prescribed ratio. In this case, recycling is a form of upcycling, where something used gets a great new purpose!

And even the organic waste generated in the recycling process is energetically utilized in our own biogas plant, producing bio-methane for your home. From the kitchen to the tank, not a drop is wasted.

How to dispose of frying oil in the OckoBox

Dispose of old fat from your household in an environmentally conscious way - the OckoBox allows you to do that. You can easily get rid of frying oil here, as well as old or expired olive oil,
sunflower oil, rapeseed oil, and used fondue oil, for example. Simply pour the completely cooled oil into a plastic container, such as an old cooking oil bottle, an empty Tetra Pak, or a can that is no longer
needed in your household, preferably using a funnel. Please do not use glass bottles for the oil. Then you can place the filled container free of charge in the OckoBox, which you can find at your supermarket
or your local recycling center. Please note: Only edible oils and fats may be disposed of in the OckoBox, under no circumstances should motor oil or other liquids be thrown in. This would disrupt the green material
cycle and endanger the recycling of frying oil and edible fats from your kitchen as a raw material for environmentally friendly biodiesel. Additionally, loose fat should not be thrown into the OckoBox.

How it works:

How fat recycling works From pot to tank

The recycling or upcycling of old cooking fat, cooking oil, and frying fat into a secondary raw material for fuel production is done by us according to the following process:

  • The collected fat from the OckoBox is brought to our production facility, where it is initially heated to approximately 60°C for about 12 hours. Then the liquid fat is emptied into a filter tank, where impurities and solids such as breadcrumbs or leftover pieces of French fries are removed.
     
  • From the filter tank, the used fat is pumped into temperature-controlled special tanks and further heated. At high temperatures, water and fat separate, with the heavier water collecting at the bottom of the tank and the lighter fat being skimmed off and centrifuged. This way, the used fat is prepared and stored in a heat-insulated tank for collection.
     
  • The separated water and organic residues from the fat are then directed to our biogas plant for further utilization. Thus, this recycling process of used fat is sustainable in treating the remaining residues produced during the process
     
  • The processed used fat can eventually be used either directly as fuel in a combined heat and power plant (CHP) for energy generation or processed as a secondary raw material in a biodiesel refinery to produce biodiesel. The glycerin residue generated during the esterification process can, in turn, be used in a biogas plant for the production of electricity and gas.

From pot to tank – that is our green material cycle

Give your used cooking oil to the OckoBOX and do something good for the environment!

Our clean recycling process eliminates wastewater pollution and prevents sewer blockages.
You can find the OckoBOX right around the corner at your local supermarket. This means short distances for environmentally friendly disposal of your used cooking oil 

Here's how the modern processing of used cooking oil works:
At our specialized facility, we heat and clean the used oil so that it can be reused as a new biofuel for transportation.
This fuel is carbon-neutral and better for the climate. It also reduces dependence on oil imports. 

How does the OckoBOX work?

1. Pour your used cooking oil into a plastic bottle.
2. Throw the filled bottles into the OckoBOX.
3. We turn it into biofuel, electricity, and gas for heating. 


You can put the following in the OckoBOX:
- Completely cooled used cooking oil
- Filled in a bottle or container
 

You CANNOT put the following in the OckoBOX:
- Oil/fat without packaging (container)
- No motor oils 
- No other liquids
