New research study concerns 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 it conserves carbon emissions by displacing fossil oil.
But such is the demand across Europe that imports now represent over half of the UCO that's made into fuel.
According to the study, external, there's no chance to prove these imports are sustainable.
Without any screening of what's can be found in, experts believe it is likewise ripe for fraud.

Reducing emissions from transport is proving to be among the toughest obstacles for governments all over the world.
They've motivated making use of biofuels as an essential methods of suppressing carbon from cars and lorries.
Biofuels are normally a mix of nonrenewable fuel source and oil made from plants or vegetables.
The truth that these crops can be re-grown and absorb more CO2 suggests they cancel out the carbon emitted when utilized in engines.
Soy and palm oil were when commonly used as elements of biodiesel but this practice has been commonly rejected because it encourages deforestation.
So for the last years approximately, the use of used cooking oil has expanded massively as an alternative feedstock for fuel.
Chip fat and other waste oils have ended up being a crucial component of biodiesel with an efficient industry emerging throughout Europe to gather and process the item.
But with the amount of biodiesel made from UCO increasing by around 40% every year given that 2014, there simply isn't sufficient chip fat to walk around.
According to a report from the project group Transport & Environment, external, majority of the UCO utilized in Europe is imported.
Their research study suggests this is highly troublesome when it pertains to impacts on the environment.
While UCO is thought about a waste product in the UK, in China, Indonesia and Malaysia it has long been utilized to feed animals. The report raises the concern 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 countries aren't available however the circulation of UCO is most likely to be similar.
With a population of around 33 million, that's close to three litres per head of used 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 collect around 5 million litres of UCO in 2019.
"Because we are purchasing it, they have actually less used cooking oil to use on the important things that they were formerly using it for," said Greg Archer with Transport & Environment.
"And they're just purchasing more virgin oil and that virgin oil is largely palm oil, because that's the most inexpensive oil available.
"So indirectly, we're just encouraging more deforestation in Southeast Asia."
Another major problem with UCO is the suspicion of fraud.
Because of demand from Europe, the price of UCO is frequently higher than palm oil. The worry is that some deceitful traders are simply watering down deliveries of UCO with palm.
As oils of various types are blended in bulk for transport, and no testing of the materials is performed, some experts believe fraud is swarming.
The recommendation of fraud anywhere along the chain of supply is rejected by the European Waste-to-Advanced Biofuels Association (EWABA), who say there are robust certification plans in location.
"It is commonly understood that the European Commission has actually taken appropriate steps to entirely curb unsound market practices in biofuel markets," stated Angel Alberdi, EWABA's secretary general.
He states a new database being developed by the EU will guarantee that trading, certification and sustainability information on all bio-liquids will need to be signed up.
"The mix of modified accreditation schemes and the pan-EU track and trace database will guarantee that no sustainability concerns develop in the whole 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, may not be efficient in stemming presumed scams.
The report from Transport & Environment explains that with shipping and air travel wanting to decarbonise by utilizing biofuels, demand for UCO could double over the next decade.
"Rising the demand beyond sustainable supply levels would increase these concerns, and risks of using 'fake' UCO, potentially resulting in indirect effects such as logging."
