The Department for Trade and Industry (DTI) has published its guidance on the End-of-Life Vehicles (ELV) Producer Responsibility Regulations 2005.
When the regulations take effect on March 3, vehicle manufacturers will be responsible for their own-brand cars that have come to the end of the road.
To help the likes of Vauxhall and Fiat understand their responsibilities and meet their obligations, the DTI has published a 76-point manual.
Vehicle recyclers had been concerned by how exactly the networks would operate.
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.
However, the guidance document states: "A producer must ensure that no individual last owner is more than 30 miles from an ATF or collection point within the network established by that producer."
Manufacturers must have their arrangements for the take-back of ELVs in place by the end of August.
