New research questions the ecological impact 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 saves carbon emissions by displacing fossil oil.
But such is the demand throughout Europe that imports now represent 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.
Without any screening of what's coming in, professionals think it is also ripe for scams.

Consumers posture 'growing risk' to tropical forests
Reducing emissions from transportation is showing to be among the toughest challenges for governments all over the world.
They've encouraged using biofuels as an essential methods of curbing carbon from automobiles and trucks.
Biofuels are generally a blend of fossil fuel and oil made from plants or veggies.
The reality that these crops can be re-grown and soak up more CO2 suggests they cancel out the carbon released when in engines.
Soy and palm oil were as soon as commonly utilized as elements of biodiesel however this practice has been extensively challenged due to the fact that it encourages deforestation.
So for the last years or so, using utilized cooking oil has broadened enormously as an alternative feedstock for fuel.
Chip fat and other waste oils have ended up being a key element of biodiesel with a reliable industry emerging throughout Europe to gather and process the product.
But with the quantity of biodiesel made from UCO increasing by around 40% every year considering that 2014, there just 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 study recommends this is extremely bothersome when it comes to influence on the environment.
While UCO is considered a waste product in the UK, in China, Indonesia and Malaysia it has actually long been used to feed animals. The report raises the concern of what individuals in these nations 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 offered however the flow of UCO is likely to be similar.
With a population of around 33 million, that's close to three litres per head of used oil that's collected and exported to the UK and Ireland alone.
By comparison, Thailand, which has a population of 70 million individuals, managed to collect around five million litres of UCO in 2019.
"Because we are purchasing it, they have less utilized cooking oil to utilize on the important things that they were formerly using it for," said Greg Archer with Transport & Environment.
"And they're simply buying more virgin oil which virgin oil is mostly palm oil, because that's the cheapest oil readily available.
"So indirectly, we're simply encouraging more logging in Southeast Asia."
Another major issue with UCO is the suspicion of scams.
Because of need from Europe, the cost of UCO is frequently greater than palm oil. The worry is that some unethical traders are merely watering down shipments of UCO with palm.
As oils of various types are mixed in bulk for transport, and no screening of the materials is performed, some experts believe scams is rife.
The suggestion of fraud anywhere along the chain of supply is declined by the European Waste-to-Advanced Biofuels Association (EWABA), who say there are robust certification plans in place.
"It is widely known that the European Commission has actually taken pertinent actions to entirely curb unsound market practices in biofuel markets," said Angel Alberdi, EWABA's secretary general.
He states a brand-new database being established by the EU will ensure that trading, accreditation and sustainability information on all bio-liquids will need to be registered.
"The mix of modified certification schemes and the pan-EU track and trace database will ensure that no sustainability problems 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, might not be efficient in stemming thought fraud.
The report from Transport & Environment explains that with shipping and aviation seeking to decarbonise by utilizing biofuels, need for UCO might double over the next decade.
"Rising the need beyond sustainable supply levels would increase these concerns, and threats of utilizing 'phony' UCO, potentially resulting in indirect effects such as logging."
