New research study concerns the environmental impact of increasing imports of utilized cooking oil (UCO) into the UK and Europe.
Chip fat and other oils are thought about waste, so when they are utilized to make biodiesel it conserves carbon emissions by displacing fossil oil.
But such is the need across Europe that imports now represent over half of the UCO that's made into fuel.
According to the study, external, there's no other way to prove these imports are sustainable.
With no testing of what's being available in, experts believe it is likewise ripe for fraud.

Reducing emissions from transport is proving to be one of the most difficult obstacles for governments all over the world.
They have actually encouraged the use of biofuels as an important methods of suppressing carbon from cars and lorries.
Biofuels are usually a blend of fossil fuel and oil made from plants or vegetables.
The fact that these crops can be re-grown and soak up more CO2 implies they cancel out the carbon emitted when used in engines.
Soy and palm oil were as soon as extensively utilized as parts of biodiesel however this practice has actually been extensively discredited because it encourages logging.
So for the last years or so, making use of utilized cooking oil has actually expanded enormously as an alternative feedstock for fuel.
Chip fat and other waste oils have actually become a key part of biodiesel with an efficient market springing up across Europe to gather and the product.
But with the amount of biodiesel made from UCO increasing by around 40% every year given that 2014, there just isn't adequate chip fat to walk around.
According to a report from the project group Transport & Environment, external, more than half of the UCO utilized in Europe is imported.
Their study suggests this is highly problematic when it comes to influence on the environment.
While UCO is thought about a waste product in the UK, in China, Indonesia and Malaysia it has actually long been utilized to feed animals. The report raises the concern of what individuals in these countries are replacing the UCO with, when it is exported.
In 2019, Malaysia exported 90 million litres of UCO to the UK and Ireland. Figures for their exports to other European nations aren't available however the flow of UCO is likely to be comparable.
With a population of around 33 million, that's close to 3 litres per head of utilized oil that's collected and exported to the UK and Ireland alone.
By contrast, Thailand, which has a population of 70 million people, managed to gather around five million litres of UCO in 2019.
"Because we are purchasing it, they have less used cooking oil to utilize on the things that they were formerly using it for," said Greg Archer with Transport & Environment.
"And they're simply buying more virgin oil and that virgin oil is largely palm oil, because that's the least expensive oil readily available.
"So indirectly, we're just encouraging more logging in Southeast Asia."
Another significant problem with UCO is the suspicion of scams.
Because of demand from Europe, the cost of UCO is often greater than palm oil. The worry is that some unethical traders are simply diluting deliveries of UCO with palm.
As oils of various types are blended in bulk for transport, and no testing of the materials is carried out, some specialists think fraud is rife.
The recommendation of fraud anywhere along the chain of supply is declined by the European Waste-to-Advanced Biofuels Association (EWABA), who say there are robust accreditation schemes in location.
"It is commonly understood that the European Commission has taken relevant actions to completely suppress unsound market practices in biofuel markets," stated Angel Alberdi, EWABA's secretary general.
He states a new database being established by the EU will guarantee that trading, accreditation and sustainability information on all bio-liquids will have to be registered.
"The mix of modified certification plans and the pan-EU track and trace database will guarantee that no sustainability concerns arise in the entire biofuels and bio-liquids supply chain," he told BBC News.
Others in the field are worried that the database concept, which was first mooted in 2018, might not be efficient in stemming suspected scams.
The report from Transport & Environment mentions that with shipping and aviation seeking to decarbonise by utilizing biofuels, demand for UCO could double over the next years.
"Rising the demand beyond sustainable supply levels would increase these concerns, and dangers of utilizing 'fake' UCO, possibly causing indirect effects such as logging."
