While laws regarding the depollution of scrapped cars came in November 2003, these latest laws fully implement the European directive, although this was supposed to happen last November.
The latest regulations were supposed to make vehicle manufacturers responsible for the costs of disposing of waste cars.
However, British Metals Recycling Association director-general Neil Marshall said: "Unfortunately it still looks like the recyclers will be bearing the majority of costs. It's just appalling."
Marshall was referring to the fact that the regulations have adopted an "own brand" system of recycling for manufacturers to meet their obligations.
This means the car companies will set up collection networks of Approved Treatment Facilities (ATFs).
While all ATFs have been licensed by the Environment Agency and have the facilities for legal depollution, the manufacturers will be able to pick and choose who they want based on factors such as cost and reputation.
Those ATFs that are not in a manufacturer's network will not be able to offer free disposal to members of the public, as they will not have been subsidised by the car companies.
Marshall added: "I have no idea why we have to have this stupid system. If we had the right system any ATF could get paid. As it is, the public will be confused because some places will take their car for nothing while others will, quite rightly, charge."
British Vehicle Salvage Federation chairman Alan Greenouff said he was worried the regulations had not prescribed a maximum distance that last owners should have to travel to dispose of their vehicles.
He added: "Manufacturers must have their network collection points dotted around the country to assure vehicles can be disposed of easily, but we are yet to learn how many each manufacturer would appoint."
