Frequently Asked Questions about handing in used cooking oil
01 What types of used oil can I hand in?
You can hand in used cooking oils from frying and deep-frying, vegetable oils such as rapeseed, sunflower or soybean oil, as well as oils used in food preserves, for example from sun-dried tomatoes, olives, canned fish or marinated cheeses.
02 Which kinds of oils are not collected?
Motor oils, mineral oils and other industrial or waste oils are not collected. We collect only used cooking oils from food preparation.
03 How should I prepare used cooking oil for handing it in?
Let the oil cool down, then strain it through a sieve to remove food scraps and other coarse impurities. Pour it into a plastic bottle that can be tightly sealed.
04 What kind of container should I bring the oil in?
Please bring the oil in a plastic bottle, container or canister. We strongly prefer transparent plastic bottles that can be tightly closed. We cannot accept glass bottles.
05 Where can I hand in used cooking oil?
You can bring your oil to collection points or to mobile collection events organized in cooperation with towns and municipalities. You can also hand it in at the Enviral, a.s. main gate on Leopoldov’s Trnavská cesta.
06 When can I bring oil to Enviral’s main gate?
You can hand in used cooking oil and fats at the Enviral main gate in Leopoldov on working days between 8:00 a.m. and 4:30 p.m. If you would like to deliver more than 100 litres, please contact us in advance.
07 Will I receive a reward for handing in used oil?
Yes. For the used cooking oil you hand in, you can choose a reward: one litre of fermented vinegar for every litre of used oil or fat, or one litre of new cooking oil for every 3 litres of used oil.
08 Do I get a reward if I leave the used oil in a public collection container?
No. Public collection containers are designed for convenient drop-off of used oil in well-sealed plastic bottles at any time, but in this case, no reward is provided.
09 How will I know when the next mobile collection is scheduled in my municipality?
Information about mobile collection dates, locations and times is published by participating towns and municipalities through leaflets, local newspapers, websites or social media. You can also find up-to-date information on the Prilej olej Facebook page or directly on this website.
10 Why shouldn’t I pour used oil down the sink or toilet?
Pouring oil down the drain can clog your pipes as well as sewage systems, make wastewater treatment more difficult, pollute water and soil and complicate the composting of kitchen bio-waste. When you hand it in for recycling, we process it and give it a second life while protecting the infrastructure and environment.
