New research questions the environmental impact of rising 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 saves carbon emissions by displacing fossil oil.
But such is the need throughout Europe that imports now represent over half of the UCO that's made into fuel.
According to the study, external, there's no other way to prove these imports are sustainable.
With no testing of what's can be found in, specialists think it is likewise ripe for scams.

Reducing emissions from transportation is showing to be among the most difficult challenges for governments all over the world.
They have actually motivated using biofuels as an essential methods of curbing carbon from automobiles and trucks.
Biofuels are typically a blend of nonrenewable fuel source and oil made from plants or vegetables.
The reality that these crops can be re-grown and soak up more CO2 implies they counteract the carbon emitted when utilized in engines.
Soy and palm oil were as soon as widely utilized as components of biodiesel but this practice has been widely rejected since it encourages deforestation.
So for the last years approximately, making use of utilized cooking oil has expanded massively as an alternative feedstock for fuel.
Chip fat and other waste oils have actually ended up being a crucial element of biodiesel with a reliable market emerging across Europe to gather and process the item.
But with the quantity of biodiesel made from UCO increasing by around 40% every year since 2014, there simply isn't sufficient chip fat to go around.
According to a report from the project group Transport & Environment, external, more than half of the UCO used in Europe is imported.
Their study suggests this is highly problematic when it comes to influence on the environment.
While UCO is thought about 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 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 however the circulation of UCO is most likely to be similar.
With a population of around 33 million, that's close to 3 litres per head of utilized oil that's collected and exported to the UK and Ireland alone.
By contrast, Thailand, which has a population of 70 million people, handled to gather around 5 million litres of UCO in 2019.
"Because we are purchasing it, they have less utilized cooking oil to use on the things that they were previously utilizing it for," stated Greg Archer with Transport & Environment.
"And they're just buying more virgin oil which virgin oil is mainly palm oil, since that's the most inexpensive oil readily available.
"So indirectly, we're simply encouraging more deforestation in Southeast Asia."
Another major issue with UCO is the suspicion of fraud.
Because of need from Europe, the rate of UCO is typically higher than palm oil. The worry is that some dishonest traders are merely diluting shipments of UCO with palm.
As oils of different types are mixed in bulk for transport, and no screening of the materials is brought out, some experts believe scams is rife.
The idea of fraud anywhere along the chain of supply is declined by the European Waste-to-Advanced Biofuels Association (EWABA), who say there are robust accreditation schemes in location.
"It is extensively understood that the European Commission has taken pertinent actions 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 information on all bio-liquids will have to be registered.
"The mix of modified certification schemes and the pan-EU track and trace database will guarantee that no sustainability problems occur in the entire biofuels and bio-liquids supply chain," he told BBC News.
Others in the field are worried that the database concept, which was very first mooted in 2018, might not be efficient in stemming suspected scams.
The report from Transport & Environment mentions that with shipping and air travel seeking to decarbonise by utilizing biofuels, demand for UCO might double over the next years.
"Rising the need beyond sustainable supply levels would increase these concerns, and dangers of utilizing 'phony' UCO, possibly resulting in indirect effects such as deforestation."
