New research concerns the environmental effect of rising imports of used cooking oil (UCO) into the UK and Europe.
Chip fat and other oils are thought about waste, so when they are used to make biodiesel it saves carbon emissions by displacing fossil oil.
But such is the demand across Europe that imports now represent majority of the UCO that's made into fuel.
According to the research study, external, there's no other way to show these imports are sustainable.
With no screening of what's coming in, professionals believe it is likewise ripe for fraud.

Reducing emissions from transport is proving to be among the toughest difficulties for federal governments all over the world.
They have actually motivated using biofuels as an essential methods of curbing carbon from cars and lorries.
Biofuels are normally a blend 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 implies they cancel out the carbon emitted when utilized in engines.
Soy and palm oil were once extensively used as elements of biodiesel but this practice has actually been widely challenged since it encourages deforestation.
So for the last decade or two, using used cooking oil has expanded enormously as an alternative feedstock for fuel.
Chip fat and other waste oils have ended up being a key component of biodiesel with a reliable industry springing up across 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 walk around.
According to a report from the campaign group Transport & Environment, external, more than half of the UCO utilized in Europe is imported.
Their research study recommends this is highly bothersome when it comes to effects on the environment.
While UCO is thought about a waste product in the UK, in China, Indonesia and Malaysia it has long been utilized 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 likely to be comparable.
With a population of around 33 million, that's close to three litres per head of utilized oil that's collected and exported to the UK and Ireland alone.
By comparison, Thailand, which has a population of 70 million people, handled to collect around 5 million litres of UCO in 2019.
"Because we are purchasing it, they have actually less used cooking oil to utilize on the things that they were previously utilizing it for," said Greg Archer with Transport & Environment.
"And they're just buying more virgin oil and that virgin oil is mostly palm oil, because that's the most inexpensive oil available.
"So indirectly, we're simply encouraging more deforestation in Southeast Asia."
Another major problem with UCO is the suspicion of fraud.
Because of demand from Europe, the cost of UCO is typically higher than palm oil. The worry is that some unethical traders are merely diluting shipments of UCO with palm.
As oils of various types are blended in bulk for transportation, and no testing of the materials is brought out, some specialists believe scams is rife.
The tip of scams 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 location.
"It is commonly known that the European Commission has actually taken pertinent steps to totally curb unsound market practices in biofuel markets," stated Angel Alberdi, EWABA's secretary general.
He states a brand-new database being developed by the EU will ensure that trading, accreditation and sustainability information on all bio-liquids will have to be signed up.
"The combination of modified certification and the pan-EU track and trace database will guarantee that no sustainability concerns develop in the entire biofuels and bio-liquids supply chain," he informed BBC News.
Others in the field are concerned that the database concept, which was very first mooted in 2018, might not work in stemming thought scams.
The report from Transport & Environment points out that with shipping and aviation seeking to decarbonise by utilizing biofuels, demand for UCO might double over the next years.
"Rising the demand beyond sustainable supply levels would increase these issues, and risks of using 'phony' UCO, potentially resulting in indirect effects such as deforestation."
