New research study questions the environmental effect of increasing imports of used 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 throughout 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.
With no testing of what's coming in, professionals think it is also ripe for fraud.

Reducing emissions from transport is proving to be among the most difficult challenges for federal governments all over the world.
They've motivated the use of biofuels as an essential means of suppressing carbon from automobiles and trucks.
Biofuels are usually 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 implies they counteract the carbon given off when utilized in engines.
Soy and palm oil were when widely utilized as elements of biodiesel however this practice has been widely challenged because it encourages logging.
So for the last years or so, the usage of utilized cooking oil has actually broadened enormously as an alternative feedstock for fuel.
Chip fat and other waste oils have ended up being a crucial part of biodiesel with a reliable market springing up throughout Europe to collect and process the product.
But with the quantity of biodiesel made from UCO increasing by around 40% every year because 2014, there simply isn't adequate chip fat to walk around.
According to a report from the campaign group Transport & Environment, external, majority of the UCO utilized in Europe is imported.
Their study recommends this is extremely bothersome when it pertains to effects on the environment.
While UCO is considered a waste material in the UK, in China, Indonesia and Malaysia it has long been utilized to feed animals. The report raises the question of what people in these nations are 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 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 comparison, Thailand, which has a population of 70 million people, managed to collect around five million litres of UCO in 2019.
"Because we are purchasing it, they have actually less utilized cooking oil to utilize on the things that they were formerly utilizing it for," stated Greg Archer with Transport & Environment.
"And they're simply purchasing more virgin oil which virgin oil is largely palm oil, because that's the cheapest oil readily available.
"So indirectly, we're just motivating more logging in Southeast Asia."
Another significant issue with UCO is the suspicion of fraud.
Because of demand from Europe, the price of UCO is typically higher than palm oil. The worry is that some dishonest traders are just diluting deliveries of UCO with palm.
As oils of various types are mixed in bulk for transportation, and no testing of the materials is performed, some professionals believe fraud is swarming.
The suggestion of scams anywhere along the chain of supply is rejected by the European Waste-to-Advanced Biofuels Association (EWABA), who state there are robust certification plans in place.
"It is commonly known that the European Commission has taken appropriate actions to totally suppress unsound market practices in biofuel markets," stated 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 have to be registered.
"The mix of revised certification plans and the pan-EU track and trace database will guarantee that no sustainability concerns occur 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 work in stemming believed fraud.
The report from Transport & Environment points out that with shipping and aviation aiming to decarbonise by utilizing biofuels, need for UCO could double over the next decade.
"Rising the demand beyond sustainable supply levels would increase these concerns, and threats of utilizing 'phony' UCO, possibly leading to indirect impacts such as logging."
