Gary Barlow has issued an apology after firing confetti cannons in one of the world's greenest venues.
The Take That singer's performance at the Eden Project in Cornwall was criticised by fans and environmental campaigners, following the move which saw fans showered with the small pieces of plastic.
Twitter account CornwallAgainstSUplastic [SU = single use] wrote: "I was appalled to see plastic confetti littering the Eden project after your last gig there.
"What on earth [sic] was a plastic confetti cannon doing there? In a place such as the Eden who are working so hard at getting rid of SU plastics."
Another critic said: "Wonder how long it will be before it's made its way to the sea and we're picking it up @GaryBarlow. Come on it's not really rocket science."
However, some fans defended him, and pointed out that many had collected the confetti at the end of the show to keep as souvenirs.
Barlow, who performed on 6 June to a sell-out crowd as part of his UK tour, has since tweeted an apology and cancelled all ticker tape at outdoor shows because "beyond the effect it just turns into litter".
"Apologies to @edenproject for firing our confetti cannons," he wrote. "I hope this doesn't mean we won't be asked back? We've cancelled all ticker tape at outdoor shows because the reality is, beyond the effect it just turns into litter."
The Eden Project opened to the public in March 2001 and launched its "Eden Sessions" the following year, which have hosted artists including Oasis, Amy Winehouse, Paulo Nutini and Muse.
