Understanding the Food Safety Act of 1990
The Food Safety Act of 1990 was introduced to maintain the safety of customers dining in restaurants, cafes, and other establishments offering food and drink for consumption. By law, businesses in these categories must follow strict rules and regulations, which also extend to managing restaurant waste and the cafe sector properly to ensure hygiene and safety standards are upheld.
key piece of legislation also evaluates how businesses dispose of food to avoid cross-contamination. This is why storing food, including cooking oil, is vital for disposal.
The Act must be followed if your business prepares, sells, or distributes food. Guidelines as per the Act include advice on how to label food items correctly and the rules for transportation and disposal.
Regarding cooking oil, the Act states that businesses must use authorized containers to store oil for disposal. Regarding waste in different sectors, including cooking oil, the Act states that businesses must use authorized containers to store oil for disposal, ensuring compliance across various industries.
Under the Food Safety Act of 1990, your business should:
- Correctly store leftover oil in authorized containers;
- Use a verified waste removal company or carrier to pick up waste oil and dispose of it;
- Refrain from throwing away food oil with their regular waste.
It is also critical to remember that local authorities can inspect food businesses anytime to ensure compliance with these regulations.
If your company is found to be in violation, the consequences can be severe. In many cases, companies will face hefty fines, but in more serious instances, non-compliance can lead to the closure of your establishment altogether.
Environmental Consequences of Improper Oil Disposal
Improper cooking oil disposal is a significant issue in, leading to various problems affecting individual households and the wider community. One of the most common and costly issues is clogged drains. When cooking oil is poured down the drain, it doesn’t disappear with water. Oil solidifies as it cools, sticking to pipes and causing mass blockages.
According to Thames Water, 6.7 million drains become clogged each year in the UK, and a large percentage of these blockages are due to improper cooking oil disposal.
The costs of clearing these blockages are enormous; approximately £88 million is spent yearly on unclogging sewers and drains across the country.
In addition to the above, there is also the ‘fatbergs’ forming issue. Fatbergs are the name given to big masses of solidified fat, oil, and grease that build up in the sewage system. They can be very complex to remove and pose substantial environmental risks.
Improper oil disposal can also lead to flooding. Drain blockages are responsible for 80% of all sewer flooding incidents in the UK, and as history has proven, flooding can cause extensive damage to homes and businesses. It can take years for the economy to recover after a severe flooding event.
How Businesses Should Dispose of Cooking Oil
Safe cooking oil disposal is not just a best practice; it’s a legal requirement for food businesses. The Food Safety Act of 1990 mandates that all food businesses in the UK dispose of used cooking oil safely and responsibly.
This involves partnering with a specialist food waste disposal company licensed to handle cooking oil removal, transportation, and disposal.
Here are the specific steps that businesses should take to dispose of cooking oil as per the laws in the U.K:
1. Store your oil properly before disposal

This includes cooking oil disposal activities such as how much oil has been disposed of, related dates, and the waste carrier’s details. Local authorities may request to review these records anytime, so it is essential to keep them up-to-date!
4. Train and educate staff

How Households Should Dispose of Cooking Oil
As you can see, businesses must follow strict obligations by law. On the other hand, households do not have to follow such rules, but you should still be mindful of disposing of cooking oil safely and adequately.
Here’s how you can safely dispose of cooking oil at home:
1. Cool the oil
After cooking, allow the oil to cool completely. Hot oil can be dangerous to handle and can cause burns or spills.
2. Reuse oil if you can
If the oil is still usable, consider using it again for cooking. This can not only help to protect the environment but also reduce oil expenses. Use a fine sieve to remove any food scraps from the oil.
3. Store your oil for safe disposal
If you do not wish to reuse the oil or cannot be used again, pour it into a sealable container, like a big plastic bottle.
4. Dispose of oil with household waste
You can dispose of your oil using your regular household waste bin. DO NOT pour cooking or other oil types down the sink or toilet. As mentioned, this can lead to severe blockages in the long term.
5. Recycle your oil if you can
Check with your council if they offer a recycling option for used cooking oil. Some areas have facilities that you can use free of charge.
