New research 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 utilized to make biodiesel it conserves carbon emissions by displacing fossil oil.
But such is the need across Europe that imports now represent more than half of the UCO that's made into fuel.
According to the study, external, there's no chance to show these imports are sustainable.
Without any screening of what's coming in, professionals believe it is also ripe for fraud.

Reducing emissions from transportation is showing to be among the toughest challenges for federal governments all over the world.
They've encouraged using biofuels as a crucial methods of suppressing carbon from automobiles and lorries.
Biofuels are generally a blend of fossil fuel and oil made from plants or vegetables.
The fact that these crops can be re-grown and absorb more CO2 means they cancel out the carbon given off when utilized in engines.
Soy and palm oil were when commonly utilized as elements of biodiesel but this practice has been commonly discredited because it motivates logging.
So for the last years or two, the use of utilized cooking oil has actually broadened enormously as an alternative feedstock for fuel.
Chip fat and other waste oils have become an essential element of biodiesel with a reliable market emerging throughout Europe to collect and process the product.
But with the quantity of biodiesel made from UCO increasing by around 40% every year considering that 2014, there merely isn't enough chip fat to go around.
According to a report from the campaign group Transport & Environment, external, majority of the UCO used in Europe is imported.
Their research study suggests this is extremely 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 actually long been utilized to feed animals. The report raises the concern of what individuals in these countries are changing 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 readily available however the flow of UCO is likely to be comparable.
With a population of around 33 million, that's close to three litres per head of utilized oil that's collected and exported to the UK and Ireland alone.
By comparison, Thailand, which has a population of 70 million individuals, handled to gather around 5 million litres of UCO in 2019.
"Because we are buying it, they have less utilized cooking oil to utilize on the important things that they were previously utilizing it for," stated Greg Archer with Transport & Environment.
"And they're simply purchasing more virgin oil and that virgin oil is mostly palm oil, since that's the most inexpensive oil available.
"So indirectly, we're just motivating more logging in Southeast Asia."
Another major problem with UCO is the suspicion of scams.
Because of demand from Europe, the cost of UCO is typically higher than palm oil. The concern is that some unscrupulous traders are just diluting shipments of UCO with palm.
As oils of various types are mixed in bulk for transportation, and no screening of the products is brought out, some professionals believe scams is rife.
The idea of scams anywhere along the chain of supply is turned down by the European Waste-to-Advanced Biofuels Association (EWABA), who state there are robust certification plans in place.
"It is widely understood that the European Commission has taken relevant actions to entirely curb unsound market practices in biofuel markets," said Angel Alberdi, EWABA's secretary general.
He says a new database being developed by the EU will make sure that trading, certification and sustainability data on all bio-liquids will need to be registered.
"The combination of modified certification plans and the pan-EU track and will make sure that no sustainability problems arise in the whole biofuels and bio-liquids supply chain," he informed BBC News.
Others in the field are concerned that the database idea, which was first mooted in 2018, might not be reliable in stemming believed scams.
The report from Transport & Environment explains that with shipping and aviation looking to decarbonise by using biofuels, need for UCO might double over the next years.
"Rising the demand beyond sustainable supply levels would increase these concerns, and risks of using 'phony' UCO, possibly leading to indirect effects such as logging."
