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 considered waste, so when they are utilized to make biodiesel it conserves carbon emissions by displacing fossil oil.
But such is the need across Europe that imports now represent more than half 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.
Without any screening of what's can be found in, professionals think it is likewise ripe for scams.

Consumers posture 'growing threat' to tropical forests
Reducing emissions from transportation is proving to be among the most difficult challenges for governments all over the world.
They've motivated making use of biofuels as an important methods of curbing carbon from vehicles and lorries.
Biofuels are generally a mix of nonrenewable fuel source and oil made from plants or veggies.
The truth that these crops can be re-grown and soak up more CO2 means they cancel out the carbon produced when utilized in engines.
Soy and palm oil were when extensively used as parts of biodiesel but this practice has been widely rejected since it motivates logging.
So for the last years approximately, the use of utilized cooking oil has actually expanded enormously as an alternative feedstock for fuel.
Chip fat and other waste oils have become an essential component 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 because 2014, there simply isn't adequate chip fat to walk around.
According to a report from the project group Transport & Environment, external, majority of the UCO used in Europe is imported.
Their study suggests this is highly troublesome when it concerns effects 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 individuals in these nations 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 countries aren't offered but the circulation 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 people, handled to collect around five 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 utilizing it for," stated Greg Archer with Transport & Environment.
"And they're simply buying more virgin oil which virgin oil is mainly palm oil, because that's the least expensive oil readily available.
"So indirectly, we're just encouraging more logging in ."
Another major issue with UCO is the suspicion of fraud.
Because of need from Europe, the price of UCO is often higher than palm oil. The worry is that some deceitful traders are just diluting shipments of UCO with palm.
As oils of different types are blended in bulk for transport, and no screening of the materials is brought out, some specialists believe fraud is swarming.
The recommendation of fraud anywhere along the chain of supply is turned down by the European Waste-to-Advanced Biofuels Association (EWABA), who say there are robust certification schemes in place.
"It is widely known that the European Commission has actually taken pertinent actions to completely curb unsound market practices in biofuel markets," said Angel Alberdi, EWABA's secretary general.
He states a new database being developed by the EU will guarantee that trading, certification and sustainability data on all bio-liquids will have to be registered.
"The combination of revised accreditation schemes and the pan-EU track and trace database will ensure that no sustainability issues emerge 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 thought scams.
The report from Transport & Environment points out that with shipping and aviation aiming to decarbonise by using biofuels, need for UCO could double over the next decade.
"Rising the demand beyond sustainable supply levels would increase these issues, and dangers of utilizing 'fake' UCO, possibly leading to indirect effects such as deforestation."
