New research study questions the environmental effect of rising 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 biodiesel it conserves carbon emissions by displacing fossil oil.
But such is the demand across Europe that imports now account for 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.
With no screening of what's being available in, specialists think it is likewise ripe for scams.

Reducing emissions from transportation is showing to be one of the toughest difficulties for governments all over the world.
They have actually motivated the usage of biofuels as an important methods of suppressing carbon from cars and trucks.
Biofuels are usually a mix of nonrenewable fuel source and oil made from plants or veggies.
The reality that these crops can be re-grown and take in more CO2 suggests they counteract the carbon emitted when used in engines.
Soy and palm oil were as soon as commonly used as parts of biodiesel but this practice has been widely challenged because it motivates deforestation.
So for the last years approximately, using utilized cooking oil has broadened massively as an alternative feedstock for fuel.
Chip fat and other waste oils have ended up being a crucial part of biodiesel with an efficient industry springing up across Europe to collect and process the item.
But with the quantity of biodiesel made from UCO increasing by around 40% every year given that 2014, there just isn't enough chip fat to walk around.
According to a report from the campaign group Transport & Environment, external, more than half of the UCO used in Europe is imported.
Their research study suggests this is highly bothersome when it pertains to effect 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 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 nations aren't available however the circulation of UCO is most likely to be comparable.
With a of around 33 million, that's close to 3 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 people, managed to collect around five million litres of UCO in 2019.
"Because we are purchasing it, they have less used cooking oil to utilize on the things that they were formerly utilizing it for," said Greg Archer with Transport & Environment.
"And they're simply purchasing more virgin oil which virgin oil is largely palm oil, since that's the cheapest oil readily available.
"So indirectly, we're simply motivating more logging in Southeast Asia."
Another significant issue with UCO is the suspicion of scams.
Because of demand from Europe, the rate of UCO is often greater than palm oil. The concern is that some unethical traders are merely diluting shipments of UCO with palm.
As oils of various types are mixed in bulk for transportation, and no testing of the materials is brought out, some experts think fraud is swarming.
The suggestion of fraud 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 commonly known that the European Commission has actually taken appropriate steps 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 guarantee that trading, accreditation and sustainability data on all bio-liquids will need to be signed up.
"The mix of modified certification schemes and the pan-EU track and trace database will ensure that no sustainability concerns arise in the entire biofuels and bio-liquids supply chain," he told BBC News.
Others in the field are worried that the database idea, which was first mooted in 2018, might not be effective in stemming thought fraud.
The report from Transport & Environment points out that with shipping and air travel 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 issues, and risks of utilizing 'fake' UCO, possibly leading to indirect impacts such as logging."
