New Prilej Olej website
A new, more user-friendly Prilej Olej website
The website for Prilej Olej, a project that has helped Slovaks dispose of used cooking oil in an environmentally responsible way for years, has undergone a complete overhaul. The new version brings a more modern, user-friendly design along with several key changes, among them an overview of upcoming collection dates, now added to the list of mobile collection points.
The new Prilej Olej website makes responsible disposal of used cooking oil even easier — for everyone who wants to help protect the environment and give used cooking oil a second chance.

Don’t pour used cooking oil down the drain. Hand it in for a reward.
The Association of Towns and Municipalities (ZMOS) wants to encourage people not to pour used cooking oil down the drain, but to collect it and hand it in for recycling instead. Municipalities that do not yet collect used oil are also being encouraged to introduce collection. How can you prevent sewer pipe blockages? Do not pour used oil into the sink — pour it into a plastic bottle and take it to your favourite collection point.
We’ve introduced Prilej Olej
We’ve introduced Prilej Olej to the mayors of the Partizánske and Prievidza districts
On June 23, 2026, a meeting of the statutory representatives of the Partizánske and Prievidza districts took place in Partizánske, where we introduced the Prilej Olej project along with its benefits for towns, municipalities, and their residents. A properly set up used cooking oil (UCO) collection system can help local governments — and therefore individual households — reduce costs, and also helps prevent environmental pollution. Also, biodiesel produced from used cooking oil helps curbing emissions.
Cooperation with ZMOS
Cooperation with ZMOS will Promote UCO Collection in Municipalities
The Prilej Olej project has established a partnership with the Association of Towns and Communities of Slovakia (ZMOS), enabling us to more effectively support Slovak municipalities in collection and environmentally responsible processing of used cooking oil. Through this initiative, we help protect sewage systems and the environment, reduce infrastructure maintenance costs for municipalities, and promote responsible behaviour among households.

Pupils in Dunajská Streda competed in collecting used cooking oil
At Dunajská Streda’s Smetanov háj Primary School, a competition in the collection of used cooking oil was held among its pupils in early 2026. Taking place in close cooperation with the Prilej Olej project, its aim was to motivate children to actively protect the environment and to emphasize the importance of proper handling of used oils. These often end up in the sewage system or municipal waste, where they cause serious damage.

Are you separating cooking oil correctly? Some municipalities motivate citizens
Household cooking oil takes more effort to sort than paper or glass. Laziness is a typical human trait, one that also shows up in waste sorting. This is doubly true for burnt oil from households, which burdens the environment, and which takes somewhat more effort to sort than paper or glass. Municipalities have now understood that more needs to be done to motivate people.

Our First Mobile Oil Collection
Do you have used cooking oil at home? Hand it in by January 16 at selected locations according to the schedule, and exchange it for vinegar or new oil. Your used cooking oil will be ecologically converted into biodiesel. We will exchange the used cooking oil you hand in for vinegar or oil. For every liter of used cooking oil, you will receive a liter of vinegar at a 1:1 ratio — 1 liter of oil for 1 liter of vinegar. For every 6 liters of used cooking oil, you will receive 1 liter of new sunflower oil.

Collection of used cooking oil and household fats
As part of its sorted waste collection system, the Municipality of Beluša collects used cooking oil and fats from households. We have prepared a short overview for you on how and where you can hand in this type of waste. Where to bring used cooking oil? The correct answer is: pour it into a PET bottle and bring it to the collection yard during its opening hours.

Collection of used cooking oil
We are aware that waste management, both in households and in the municipality, is a pressing issue. We have gradually begun addressing it, even though conditions in for sorting waste are not yet fully optimal in Beluša. Over the summer, we will be working on the registration of communal waste bins and will endeavour to change attitudes toward sorted waste through education.

Enviral: Looking to Expand Production While Minimizing Impact on the Environment
Among the activities the company has showcased are two community projects, "Every Drop of Oil Counts" and "Prilej Olej" (Pour In Oil), both centered on collecting used cooking oil for further processing. Used cooking oil is now collected at 212 filling stations across 118 towns and villages. The pilot project was launched by Slovnaft, with the Leopoldov-based company Meroco on board as a partner since 2015. Once processed, the used cooking oil can be reused as part of the biofuel component in motor fuels.

Households get a reward for collecting used cooking oil and fats
In cooperation with Meroco, the Municipality of Beluša has prepared a new offer for its citizens: a reward for collecting used cooking oil. How does it work? After using the oil in the kitchen, let it cool, strain it through a sieve to remove coarse impurities, and pour it into a clear, resealable bottle. Oil used as a preservative liquid for foods such as sardines or olives is also suitable for collection. Mineral, motor, and other waste oils must never be placed in the container!
