New research study concerns the ecological 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 emissions by displacing fossil oil.
But such is the demand throughout Europe that imports now represent majority of the UCO that's made into fuel.
According to the research study, external, there's no way to show these imports are sustainable.
With no screening of what's being available in, experts believe it is likewise ripe for fraud.

Reducing emissions from transportation is proving to be among the toughest challenges for federal governments all over the world.
They have actually motivated using biofuels as an important methods of curbing carbon from cars and trucks and trucks.
Biofuels are generally a blend of fossil fuel and oil made from plants or vegetables.
The fact that these crops can be re-grown and soak up more CO2 implies they counteract the carbon given off when used in engines.
Soy and palm oil were when commonly used as parts of biodiesel but this practice has actually been commonly rejected since it encourages deforestation.
So for the last decade or so, the usage of used cooking oil has broadened enormously as an alternative feedstock for fuel.
Chip fat and other waste oils have become a crucial part of biodiesel with an effective industry springing up across Europe to gather and process the item.
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 go around.
According to a report from the campaign group Transport & Environment, external, over half of the UCO utilized in Europe is imported.
Their research study suggests this is extremely problematic when it concerns effects on the environment.
While UCO is considered a waste product in the UK, in China, Indonesia and Malaysia it has long been used to feed animals. The report raises the concern of what individuals 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 offered but the flow of UCO is most likely to be comparable.
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 5 million litres of UCO in 2019.
"Because we are buying it, they have actually less utilized cooking oil to use on the things that they were previously using it for," stated Greg Archer with Transport & Environment.
"And they're just buying more virgin oil which virgin oil is mostly palm oil, because that's the most inexpensive oil offered.
"So indirectly, we're simply encouraging more logging in Southeast Asia."
Another significant problem with UCO is the suspicion of fraud.
Because of demand from Europe, the cost of UCO is typically greater than palm oil. The worry is that some unscrupulous traders are merely diluting shipments of UCO with palm.
As oils of different types are blended in bulk for transportation, and no testing of the products is performed, some experts think scams is rife.
The recommendation of scams 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 understood that the European Commission has actually taken relevant steps to entirely suppress unsound market practices in biofuel markets," said Angel Alberdi, EWABA's secretary general.
He states a brand-new database being developed by the EU will guarantee that trading, accreditation and sustainability information on all bio-liquids will have to be signed up.
"The combination of revised accreditation schemes and the pan-EU track and trace database will guarantee that no sustainability issues occur 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 very first mooted in 2018, might not be effective in stemming thought fraud.
The report from Transport & Environment mentions that with shipping and air travel aiming to decarbonise by utilizing biofuels, need for UCO might double over the next years.
"Rising the demand beyond sustainable supply levels would increase these issues, and threats of using 'phony' UCO, potentially causing indirect effects such as deforestation."
