Chelsea are working with the Premier League and Sky Ocean Rescue to reduce the use of plastic at their club.
The Blues are looking to limit plastic waste at games, where many fans are given drinks in plastic cups and food on plastic plates.
There will be an offer of reusable cups to fans for beers or other beverages, while the stadium will have drop off points to put those cups away when fans are about to leave the stadium.
These cups will be washed and then used again for future matchdays.
The goal is a joint initiative from the Premier League and Sky Ocean Rescue, aiming to teach the fans about the dangers of excessive plastic waste.
Some other clubs in the league, including Arsenal and Fulham, have also trialled the initiative recently.
