New research study concerns the ecological effect of increasing imports of used 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 prove these imports are sustainable.
Without any screening of what's can be found in, professionals think it is also ripe for fraud.

Consumers posture 'growing danger' to tropical forests
Reducing emissions from is showing to be among the toughest challenges for governments all over the world.
They have actually motivated the use of biofuels as an essential methods of curbing carbon from automobiles and lorries.
Biofuels are typically a mix of nonrenewable fuel source and oil made from plants or vegetables.
The truth that these crops can be re-grown and soak up more CO2 indicates they cancel out the carbon emitted when used in engines.
Soy and palm oil were as soon as commonly used as components of biodiesel but this practice has actually been commonly discredited because it motivates deforestation.
So for the last decade or two, making use of utilized cooking oil has actually expanded massively as an alternative feedstock for fuel.
Chip fat and other waste oils have ended up being an essential part of biodiesel with an efficient industry springing up across 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 just isn't sufficient chip fat to walk around.
According to a report from the campaign group Transport & Environment, external, over half of the UCO used in Europe is imported.
Their research study suggests this is extremely troublesome when it comes to effects on the environment.
While UCO is considered a waste material in the UK, in China, Indonesia and Malaysia it has long been used to feed animals. The report raises the question of what people in these nations 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 readily available but the flow 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 gathered and exported to the UK and Ireland alone.
By contrast, Thailand, which has a population of 70 million individuals, handled to collect around five million litres of UCO in 2019.
"Because we are buying it, they have less utilized cooking oil to utilize on the things that they were previously utilizing it for," said Greg Archer with Transport & Environment.
"And they're simply buying more virgin oil which virgin oil is mostly palm oil, since that's the cheapest oil available.
"So indirectly, we're simply motivating more logging in Southeast Asia."
Another major issue with UCO is the suspicion of scams.
Because of demand from Europe, the price of UCO is frequently higher than palm oil. The concern is that some unethical traders are merely diluting deliveries of UCO with palm.
As oils of different types are blended in bulk for transport, and no screening of the products is carried out, some specialists believe scams is rife.
The idea 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 schemes in place.
"It is widely understood that the European Commission has actually taken pertinent steps to completely suppress 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, accreditation and sustainability data on all bio-liquids will have to be registered.
"The combination of modified accreditation schemes and the pan-EU track and trace database will guarantee that no sustainability problems emerge in the entire biofuels and bio-liquids supply chain," he told BBC News.
Others in the field are concerned that the database concept, which was very first mooted in 2018, may not be efficient in stemming thought fraud.
The report from Transport & Environment points out that with shipping and air travel looking to decarbonise by utilizing biofuels, need for UCO could double over the next years.
"Rising the demand beyond sustainable supply levels would increase these issues, and risks of using 'phony' UCO, possibly causing indirect impacts such as logging."
