New research study questions the ecological effect of increasing imports of utilized cooking oil (UCO) into the UK and Europe.
Chip fat and other oils are considered waste, so when they are used to make biodiesel it saves carbon emissions by displacing fossil oil.
But such is the demand across Europe that imports now account for more than half of the UCO that's made into fuel.
According to the research study, external, there's no other way to prove these imports are sustainable.
With no testing of what's can be found in, professionals believe it is likewise ripe for fraud.

Reducing emissions from transportation is showing to be among the toughest difficulties for federal governments all over the world.
They've motivated using biofuels as an important ways of suppressing carbon from automobiles and trucks.
Biofuels are a blend of fossil fuel and oil made from plants or vegetables.
The reality that these crops can be re-grown and take in more CO2 suggests they counteract the carbon released when used in engines.
Soy and palm oil were as soon as widely utilized as elements of biodiesel but this practice has actually been commonly rejected because it encourages logging.
So for the last years or two, the use of used cooking oil has actually expanded enormously as an alternative feedstock for fuel.
Chip fat and other waste oils have become an essential component of biodiesel with an efficient industry springing up throughout Europe to collect and process the item.
But with the amount of biodiesel made from UCO increasing by around 40% every year because 2014, there simply isn't adequate chip fat to go around.
According to a report from the project group Transport & Environment, external, majority of the UCO used in Europe is imported.
Their research study recommends this is extremely bothersome when it pertains to influence on the environment.
While UCO is considered a waste material in the UK, in China, Indonesia and Malaysia it has actually long been used to feed animals. The report raises the question of what people 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 but the circulation of UCO is likely to be similar.
With a population of around 33 million, that's close to 3 litres per head of utilized oil that's gathered and exported to the UK and Ireland alone.
By contrast, Thailand, which has a population of 70 million people, handled to collect around 5 million litres of UCO in 2019.
"Because we are buying it, they have actually less utilized cooking oil to use on the things that they were formerly utilizing it for," stated Greg Archer with Transport & Environment.
"And they're simply purchasing more virgin oil and that virgin oil is mainly palm oil, since that's the cheapest oil readily available.
"So indirectly, we're just motivating more logging in Southeast Asia."
Another major problem with UCO is the suspicion of fraud.
Because of need from Europe, the rate of UCO is often higher than palm oil. The worry is that some unscrupulous traders are just diluting shipments of UCO with palm.
As oils of various types are mixed in bulk for transport, and no testing of the materials is brought out, some professionals believe fraud is swarming.
The recommendation of scams anywhere along the chain of supply is rejected by the European Waste-to-Advanced Biofuels Association (EWABA), who say there are robust accreditation plans in location.
"It is commonly understood that the European Commission has taken pertinent actions to completely suppress unsound market practices in biofuel markets," stated Angel Alberdi, EWABA's secretary general.
He states a brand-new database being established by the EU will ensure that trading, certification and sustainability data on all bio-liquids will need to be signed up.
"The mix of modified certification plans and the pan-EU track and trace database will ensure that no sustainability problems emerge in the entire biofuels and bio-liquids supply chain," he told BBC News.
Others in the field are worried that the database idea, which was very first mooted in 2018, might not work in stemming presumed scams.
The report from Transport & Environment points out that with shipping and air travel wanting to decarbonise by utilizing biofuels, need for UCO might double over the next years.
"Rising the demand beyond sustainable supply levels would increase these issues, and threats of using 'fake' UCO, potentially causing indirect effects such as logging."
