New research questions the ecological effect of increasing imports of used 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 across Europe that imports now account for over half of the UCO that's made into fuel.
According to the research study, external, there's no chance to prove these imports are sustainable.
With no screening of what's coming in, professionals believe it is also ripe for fraud.

Reducing emissions from transport is proving to be one of the hardest difficulties for governments all over the world.
They've motivated the usage of biofuels as an important means of suppressing carbon from cars and trucks.
Biofuels are generally a blend 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 suggests they cancel out the carbon given off when used in engines.
Soy and palm oil were once commonly utilized as elements of biodiesel but this practice has actually been commonly challenged due to the fact that it encourages deforestation.
So for the last years or two, the use of used cooking oil has broadened enormously as an alternative feedstock for fuel.
Chip fat and other waste oils have become a key component of biodiesel with an emerging throughout 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, majority of the UCO utilized in Europe is imported.
Their study suggests this is extremely problematic when it pertains to effect 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 readily available but the flow 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 contrast, Thailand, which has a population of 70 million people, handled to gather around five million litres of UCO in 2019.
"Because we are buying it, they have 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 just purchasing more virgin oil which virgin oil is mostly palm oil, since that's the most inexpensive oil available.
"So indirectly, we're simply motivating more logging in Southeast Asia."
Another significant problem with UCO is the suspicion of fraud.
Because of demand from Europe, the rate of UCO is frequently higher than palm oil. The concern is that some unscrupulous traders are just watering down deliveries of UCO with palm.
As oils of various types are blended in bulk for transport, and no testing of the products is brought out, some specialists believe scams is swarming.
The idea of scams anywhere along the chain of supply is declined by the European Waste-to-Advanced Biofuels Association (EWABA), who state there are robust accreditation plans in location.
"It is extensively known that the European Commission has taken appropriate actions to entirely suppress unsound market practices in biofuel markets," stated Angel Alberdi, EWABA's secretary general.
He says a brand-new database being developed by the EU will make sure that trading, certification and sustainability data on all bio-liquids will have to be registered.
"The combination of modified accreditation schemes and the pan-EU track and trace database will guarantee that no sustainability concerns arise in the entire biofuels and bio-liquids supply chain," he told BBC News.
Others in the field are worried that the database concept, which was first mooted in 2018, may not work in stemming thought scams.
The report from Transport & Environment points out that with shipping and air travel aiming to decarbonise by utilizing biofuels, demand for UCO might double over the next decade.
"Rising the demand beyond sustainable supply levels would increase these concerns, and threats of utilizing 'phony' UCO, possibly causing indirect effects such as deforestation."
