Britain's biggest nightclub operator Luminar says 87% of its venues now serve all drinks in polycarbonate containers.
The move to plastics has halved insurance premiums as fewer claims are made, Luminar chief executive Steve Thomas told the MA.
Thomas also revealed 15% of bottled drinks sold at its bars are in plastic PET containers - and he is "shouting" at producers to provide more plastic bottles.
Last spring Luminar, which operates more than 200 premises, announced moves to go completely glass-free in 12 months.
Thomas said this week: "Across the estate we are 87% compliant. That includes glasses in VIP areas that we said we would maintain. As we replace glasses we will replace them with polycarbonates.
"We think it's done fantastic things for us. We have fewer insurance claims. Premiums are down as there's no broken glass.
"Where there is an incident - and these are rare - there's not been major damage to the individual."
Thomas said a small number of drinks brands, including Stella Artois and VK Vodka Kick, are available in PET bottles.
When asked if he is asking more producers to release brands in plastic containers, Thomas said: "We are shouting at them more like.
"They are going to have to at some stage if they want them to be stocked with us."
