Trinity College says its campus is to become a disposable plastic free zone in the next two years.
It's set to phase out disposable plastic containers and utensils.
It's asked students to decide which items to start with by voting in an online poll.
Among the options are to replace disposable glasses with reusable ones, abolish all plastic cutlery and replace all straws with biodegradable ones.
The college says: "All of single-use plastic cups from the Buttery (dining hall) will end up in the rubbish, and from there into a landfill or incinerator.
"Plastic takes over 200 years to decompose, and it leaks pollutants into the soil and water.
"As part of the Plastic Free Campus campaign - let's do what we can... to stop adding to landfills."
