New research study questions the environmental effect of rising imports of utilized cooking oil (UCO) into the UK and Europe.
Chip fat and other oils are thought about 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 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 screening of what's coming in, specialists believe it is likewise ripe for fraud.

Reducing emissions from transportation is proving to be one of the hardest difficulties for governments all over the world.
They have actually motivated using biofuels as an essential means of suppressing carbon from cars and lorries.
Biofuels are usually a mix of fossil fuel and oil made from plants or vegetables.
The fact that these crops can be re-grown and absorb more CO2 indicates they counteract the carbon released when used in engines.
Soy and palm oil were as soon as commonly utilized as parts of biodiesel but this practice has actually been extensively challenged since it motivates deforestation.
So for the last decade or two, using used cooking oil has actually expanded massively as an alternative feedstock for fuel.
Chip fat and other waste oils have become a key part of biodiesel with a reliable market springing up across Europe to collect 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 in Europe is imported.
Their study recommends this is highly problematic when it pertains to impacts on the environment.
While UCO is thought about a waste material 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 but 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 contrast, Thailand, which has a population of 70 million people, managed to gather around five million litres of UCO in 2019.
"Because we are buying it, they have 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 simply purchasing more virgin oil and that virgin oil is mostly palm oil, since that's the most affordable oil available.
"So indirectly, we're just encouraging more logging in Southeast Asia."
Another major issue with UCO is the suspicion of fraud.
Because of need from Europe, the rate of UCO is typically greater than palm oil. The concern is that some unethical traders are merely diluting deliveries of UCO with palm.
As oils of various types are mixed in bulk for transport, and no testing of the products is carried out, some professionals believe fraud is swarming.
The tip 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 schemes in place.
"It is commonly understood that the European Commission has actually taken pertinent actions to entirely curb unsound market practices in biofuel markets," stated Angel Alberdi, EWABA's secretary general.
He says a new database being established by the EU will make sure that trading, certification and sustainability information on all bio-liquids will need to be signed up.
"The mix of revised accreditation plans and the pan-EU track and trace database will make sure that no sustainability problems occur 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 first mooted in 2018, might not be effective in stemming suspected fraud.
The report from Transport & Environment mentions that with shipping and air travel seeking to decarbonise by utilizing biofuels, need for UCO could double over the next decade.
"Rising the demand beyond sustainable supply levels would increase these issues, and threats of utilizing 'phony' UCO, potentially resulting in indirect impacts such as logging."
