New research study questions the environmental impact of rising imports of used (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 need throughout Europe that imports now represent majority of the UCO that's made into fuel.
According to the study, external, there's no other way to prove these imports are sustainable.
Without any testing of what's can be found in, specialists believe it is likewise ripe for scams.

Reducing emissions from transport is proving to be one of the most difficult obstacles for governments all over the world.
They've motivated the usage of biofuels as a crucial methods of curbing carbon from cars and trucks.
Biofuels are typically a mix of nonrenewable fuel source and oil made from plants or veggies.
The reality that these crops can be re-grown and take in more CO2 means they cancel out the carbon given off when used in engines.
Soy and palm oil were as soon as widely utilized as elements of biodiesel but this practice has been commonly discredited because it motivates deforestation.
So for the last years approximately, making use of used cooking oil has actually broadened enormously as an alternative feedstock for fuel.
Chip fat and other waste oils have become a key part of biodiesel with an efficient industry emerging across Europe to collect and process the product.
But with the amount of biodiesel made from UCO increasing by around 40% every year since 2014, there simply isn't adequate 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 highly problematic when it comes to impacts on the environment.
While UCO is considered a waste material in the UK, in China, Indonesia and Malaysia it has long been used to feed animals. The report raises the question of what people in these countries 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 countries aren't offered but the flow of UCO is likely to be comparable.
With a population of around 33 million, that's close to 3 litres per head of used oil that's collected and exported to the UK and Ireland alone.
By comparison, Thailand, which has a population of 70 million people, handled 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 things that they were previously utilizing it for," stated Greg Archer with Transport & Environment.
"And they're just buying more virgin oil which virgin oil is mainly palm oil, since that's the cheapest oil readily available.
"So indirectly, we're simply encouraging more deforestation in Southeast Asia."
Another significant issue with UCO is the suspicion of fraud.
Because of demand from Europe, the price of UCO is frequently greater than palm oil. The concern is that some unscrupulous traders are simply diluting shipments of UCO with palm.
As oils of various types are blended in bulk for transportation, and no testing of the products is brought out, some experts think scams is swarming.
The idea of fraud anywhere along the chain of supply is rejected by the European Waste-to-Advanced Biofuels Association (EWABA), who state there are robust certification plans in location.
"It is widely understood that the European Commission has taken appropriate steps to completely curb unsound market practices in biofuel markets," stated Angel Alberdi, EWABA's secretary general.
He says a brand-new database being established by the EU will make sure that trading, certification and sustainability data on all bio-liquids will need to be registered.
"The combination of revised certification plans 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 very first mooted in 2018, might not be efficient in stemming believed scams.
The report from Transport & Environment points out that with shipping and aviation aiming to decarbonise by utilizing biofuels, demand for UCO might double over the next years.
"Rising the need beyond sustainable supply levels would increase these concerns, and threats of utilizing 'phony' UCO, possibly resulting in indirect impacts such as logging."
