Fines for littering and dog fouling will be increased by €100 from the beginning of September.
Minister of State for the Circular Economy Alan Dillon will announce that these on-the-spot fines will rise from €150 to €250.
The move is aimed at deterring littering and illegal dumping, and the minister will encourage local authorities to improve enforcement.
Mr Dillon will also announce a €3 million investment in anti-dumping initiatives across all councils.
More than 200 projects will receive funding this year.
This will fund local authorities to use CCTV monitoring along with supporting clean up operations and raising public awareness.
Since 2017, this work has led to the removal of more than 26,000 tonnes of waste nationwide.
