New research study concerns the ecological impact 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 used to make biodiesel it conserves carbon emissions by displacing fossil oil.
But such is the demand throughout Europe that imports now account for majority of the UCO that's made into fuel.
According to the study, external, there's no way to show these imports are sustainable.
With no testing of what's can be found in, think it is likewise ripe for fraud.

Reducing emissions from transportation is proving to be one of the most difficult difficulties for federal governments all over the world.
They have actually encouraged using biofuels as an important means of suppressing carbon from vehicles and lorries.
Biofuels are normally 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 suggests they counteract the carbon given off when used in engines.
Soy and palm oil were once commonly used as elements of biodiesel however this practice has been commonly discredited due to the fact that it encourages deforestation.
So for the last years or two, using utilized cooking oil has actually expanded enormously as an alternative feedstock for fuel.
Chip fat and other waste oils have become a crucial component 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 given that 2014, there simply isn't sufficient chip fat to walk around.
According to a report from the campaign group Transport & Environment, external, over half of the UCO utilized in Europe is imported.
Their study recommends this is extremely troublesome when it concerns influence on the environment.
While UCO is thought about a waste material in the UK, in China, Indonesia and Malaysia it has actually long been utilized to feed animals. The report raises the concern of what people 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 available however the flow 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 individuals, managed to gather around five million litres of UCO in 2019.
"Because we are buying it, they have actually less utilized cooking oil to utilize on the important things that they were previously utilizing it for," said Greg Archer with Transport & Environment.
"And they're just purchasing more virgin oil and that virgin oil is mostly palm oil, since that's the most affordable 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 need from Europe, the price of UCO is frequently higher than palm oil. The concern is that some unethical traders are just diluting deliveries of UCO with palm.
As oils of various types are blended in bulk for transportation, and no testing of the materials is brought out, some specialists think scams is swarming.
The suggestion of fraud anywhere along the chain of supply is declined by the European Waste-to-Advanced Biofuels Association (EWABA), who state there are robust certification schemes in place.
"It is widely understood that the European Commission has actually taken pertinent steps to totally curb unsound market practices in biofuel markets," said Angel Alberdi, EWABA's secretary general.
He says a brand-new database being developed by the EU will ensure that trading, certification and sustainability data on all bio-liquids will need to be registered.
"The mix of modified certification schemes and the pan-EU track and trace database will guarantee that no sustainability issues emerge in the entire 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 presumed fraud.
The report from Transport & Environment mentions that with shipping and air travel wanting to decarbonise by using 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 'fake' UCO, potentially leading to indirect impacts such as deforestation."
