Schulze made this known in an interview with the Sunday edition of the Bild newspaper.
“My ministry is currently working on the legal regulations for a plastic bag ban,” Schulze said.
She added that a voluntary agreement with businesses since 2016 to reduce the number of plastic bags had been a success.
“We can now secure that (success) with a ban,” she stated.
The report did not say when the draft laws would be completed.
In July, Markus Soeder, the state premier of Bavaria and head of Germany’s conservative Christian Social Union (CSU), said he was launching a Germany-wide push for a plastic bag ban.
Schulze had previously expressed skepticism towards laws banning plastic bags, arguing that they would require more time to initiate than voluntary steps.
Under a voluntary agreement, supermarkets charge customers for plastic bags.
