Plans to ban single-use plastic items including straws, cotton buds and polystyrene food and drinks containers is being considered by the Welsh Government.
It wants a zero waste Wales by 2050.
Deputy Minister for Housing and Local Government Hannah Blythyn will launch a public consultation on the proposals at a beach clean on Anglesey on Thursday.
The Welsh Government said as coronavirus lockdown restrictions ease, littering has become more prominent.
Ms Blythyn said: “Plastic pollution and the impact it has on our environment is regularly highlighted in the media, online and in conversations I have every day with people across Wales.
“It blights our communities and has a devastating impact on our wildlife.”
Lesley Jones, CEO of Keep Wales Tidy, welcomed the launch of the consultation, saying: “The damage caused by plastics is far reaching and we are eager to see a drive towards reusable alternatives across society.”
She said she hoped the consultation would “lead to a series of bold policy actions by government to reduce plastic at source”.
