New research study concerns the ecological impact of increasing imports of utilized 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 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 show these imports are sustainable.
With no testing of what's coming in, professionals think it is also ripe for scams.

Consumers present 'growing hazard' to tropical forests
Reducing emissions from transport is showing to be one of the most difficult obstacles for federal governments all over the world.
They have actually motivated the use of biofuels as a crucial methods of suppressing carbon from vehicles 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 given off when used in engines.
Soy and palm oil were once commonly utilized as components of biodiesel but this practice has been extensively discredited because it encourages logging.
So for the last years or two, making use of used cooking oil has actually expanded massively as an alternative feedstock for fuel.
Chip fat and other waste oils have actually ended up being an essential component of biodiesel with an efficient industry springing up throughout Europe to collect and process the item.
But with the quantity of biodiesel made from UCO increasing by around 40% every year since 2014, there just isn't enough chip fat to go around.
According to a report from the project group Transport & Environment, external, over half of the UCO utilized in Europe is imported.
Their research study suggests this is highly troublesome when it pertains to influence on the environment.
While UCO is thought about 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 people 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 likely to be comparable.
With a population of around 33 million, that's close to 3 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 individuals, managed to gather around five million litres of UCO in 2019.
"Because we are purchasing it, they have actually less used cooking oil to use on the important things that they were previously utilizing it for," stated Greg Archer with Transport & Environment.
"And they're simply purchasing more virgin oil and that virgin oil is mainly palm oil, since that's the most inexpensive oil offered.
"So indirectly, we're just encouraging more logging in Southeast Asia."
Another significant problem with UCO is the suspicion of fraud.
Because of need from Europe, the cost of UCO is often greater than palm oil. The worry is that some deceitful traders are simply watering down deliveries of UCO with palm.
As oils of various types are blended in bulk for transport, and no testing of the materials is brought out, some professionals believe fraud is rife.
The tip of scams anywhere along the chain of supply is declined by the European Waste-to-Advanced Biofuels Association (EWABA), who say there are robust accreditation schemes in place.
"It is commonly understood that the European Commission has actually taken pertinent steps to entirely curb unsound market practices in biofuel markets," said Angel Alberdi, EWABA's secretary general.
He says a brand-new database being developed by the EU will ensure that trading, accreditation and sustainability information on all bio-liquids will need to be signed up.
"The combination of modified accreditation plans and the pan-EU track and trace database will guarantee that no sustainability concerns occur in the entire biofuels and bio-liquids supply chain," he informed BBC News.
Others in the field are concerned that the database idea, which was first mooted in 2018, may not work in stemming believed scams.
The report from Transport & Environment mentions that with shipping and aviation looking to decarbonise by utilizing biofuels, need for UCO could double over the next years.
"Rising the demand beyond sustainable supply levels would increase these issues, and risks of utilizing 'fake' UCO, potentially causing indirect effects such as logging."
