Defra has confirmed that it will soon issue a consultation on the packaging waste regulations before making "technical changes" to the legislation.
The consultation should consider a number of loopholes that have allowed some packaging producers to avoid producer responsibility for packaging waste.
A spokesman from Defra confirmed that the consultation document was likely to be issued "mid-August".
The loopholes involve companies based abroad, outside the jurisdiction of UK regulations. It is believed some changes are also needed in franchise packaging and leased packaging regulations.
One of the larger companies that is currently not paying for packaging to be recycled in the UK is PepsiCo - which owns Pepsi Cola, Walkers Crisps and Quaker Cereals.
A spokeswoman for the Environment Agency confirmed: "PepsiCo is not registered. It is part of a gap in the regulations which should be sorted in a forthcoming consultation from Defra. The regulation needs to be amended, but this will be part of the consultation."
PepsiCo is based in Switzerland and as a result the Environment Agency has no jurisdiction to enforce compliance with the UK's producer responsibility regulations.
Although legally PepsiCo is doing nothing wrong, by failing to take part in the packaging system the company could be significantly holding back the amount of investment going into UK recycling.
This is because recycling target were set assuming these companies would take part.
The company's Walkers brand alone is responsible for putting over 5.2 billion bags of crisps on the UK market each year.
Commenting on its non-registration within the packaging producer responsibility system, a spokesperson for PepsiCo said: "We are of course concerned about pack recycling and the biggest issue we face as a business is the practicality of getting consumers to recycle their empty packs."
