New research study concerns the environmental effect of rising imports of used 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 conserves carbon emissions by displacing fossil oil.
But such is the demand throughout Europe that imports now account for more than half of the UCO that's made into fuel.
According to the research study, external, there's no method to prove these imports are sustainable.
With no testing of what's coming in, professionals think it is also ripe for scams.

Reducing emissions from transportation is proving to be among the toughest obstacles for governments all over the world.
They've encouraged the usage of biofuels as an important methods of curbing carbon from vehicles and trucks.
Biofuels are normally a blend of fossil fuel and oil made from plants or vegetables.
The reality that these crops can be re-grown and soak up more CO2 means they counteract the carbon given off when used in engines.
Soy and palm oil were once extensively used as elements of biodiesel but this practice has been widely rejected due to the fact that it motivates deforestation.
So for the last decade or so, making use of utilized cooking oil has broadened massively as an alternative feedstock for fuel.
Chip fat and other waste oils have actually ended up being an essential component of biodiesel with a reliable industry emerging throughout Europe to collect and process the product.
But with the amount 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, more than half of the UCO used in Europe is imported.
Their study recommends this is extremely bothersome when it pertains to impacts on the environment.
While UCO is considered a waste product in the UK, in China, Indonesia and Malaysia it has actually 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 countries aren't available however 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 individuals, handled to collect around 5 million litres of UCO in 2019.
"Because we are buying it, they have less utilized cooking oil to utilize on the things that they were formerly utilizing it for," said Greg Archer with Transport & Environment.
"And they're simply purchasing more virgin oil which virgin oil is mainly palm oil, since that's the most affordable oil readily available.
"So indirectly, we're simply encouraging more logging in Southeast Asia."
Another significant issue with UCO is the suspicion of scams.
Because of need from Europe, the price of UCO is often greater than palm oil. The worry is that some deceitful traders are just watering down shipments of UCO with palm.
As oils of various types are blended in bulk for transport, and no testing of the products is performed, some professionals think scams is swarming.
The tip of scams anywhere along the chain of supply is rejected by the European Waste-to-Advanced Biofuels Association (EWABA), who state there are robust accreditation plans in place.
"It is extensively known that the European Commission has actually taken pertinent actions to entirely curb unsound market practices in biofuel markets," said Angel Alberdi, EWABA's secretary general.
He says a new database being established by the EU will ensure that trading, certification and sustainability information on all bio-liquids will need to be signed up.
"The mix of revised certification schemes and the pan-EU track and trace database will ensure that no sustainability problems arise in the whole biofuels and bio-liquids supply chain," he informed BBC News.
Others in the field are worried that the database idea, which was very first mooted in 2018, might not be efficient in stemming believed fraud.
The report from Transport & Environment points out that with shipping and aviation wanting to decarbonise by utilizing biofuels, need for UCO could double over the next years.
"Rising the demand beyond sustainable supply levels would increase these concerns, and dangers of utilizing 'phony' UCO, potentially leading to indirect effects such as deforestation."
