New research study questions the environmental 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 utilized to make biodiesel it conserves carbon emissions by displacing fossil oil.
But such is the demand across 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 being available in, specialists believe it is likewise ripe for scams.

Consumers posture 'growing hazard' to tropical forests
Reducing emissions from transportation is showing to be among the most difficult obstacles for all over the world.
They've encouraged using biofuels as an important ways of suppressing carbon from cars and trucks and trucks.
Biofuels are typically a mix of fossil fuel and oil made from plants or vegetables.
The reality that these crops can be re-grown and absorb more CO2 means they counteract the carbon released when used in engines.
Soy and palm oil were as soon as widely utilized as components of biodiesel but this practice has been extensively rejected because it encourages logging.
So for the last decade or so, making use of used cooking oil has expanded massively as an alternative feedstock for fuel.
Chip fat and other waste oils have actually ended up being a crucial part of biodiesel with an efficient market emerging throughout Europe to collect and process the item.
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, over half of the UCO used in Europe is imported.
Their study suggests this is highly problematic when it pertains to effect on the environment.
While UCO is considered a waste product in the UK, in China, Indonesia and Malaysia it has actually long been utilized to feed animals. The report raises the question of what people in these countries 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 countries aren't offered but the flow of UCO is likely to be comparable.
With a population of around 33 million, that's close to 3 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 actually less utilized cooking oil to utilize on the important things that they were previously using it for," said Greg Archer with Transport & Environment.
"And they're simply purchasing more virgin oil and that virgin oil is mostly palm oil, because that's the most affordable oil offered.
"So indirectly, we're just motivating more logging in Southeast Asia."
Another significant problem with UCO is the suspicion of fraud.
Because of need from Europe, the price of UCO is often greater than palm oil. The concern is that some dishonest traders are merely diluting deliveries of UCO with palm.
As oils of different types are mixed in bulk for transport, and no testing of the products is brought out, some experts believe scams is swarming.
The tip of fraud anywhere along the chain of supply is rejected by the European Waste-to-Advanced Biofuels Association (EWABA), who say there are robust certification schemes in place.
"It is extensively known that the European Commission has taken appropriate actions to entirely curb unsound market practices in biofuel markets," stated Angel Alberdi, EWABA's secretary general.
He says a brand-new database being established by the EU will guarantee that trading, accreditation and sustainability information on all bio-liquids will have to be registered.
"The combination of modified accreditation plans and the pan-EU track and trace database will guarantee that no sustainability issues arise in the whole biofuels and bio-liquids supply chain," he informed BBC News.
Others in the field are worried that the database concept, which was very first mooted in 2018, may not be reliable in stemming suspected scams.
The report from Transport & Environment mentions that with shipping and aviation looking to decarbonise by using biofuels, demand for UCO could double over the next decade.
"Rising the demand beyond sustainable supply levels would increase these issues, and risks of using 'fake' UCO, possibly causing indirect effects such as deforestation."
