In four Asda stores in Leeds, neck collars and jar tags were attached to bottles of Asda wine, spirits and beers as well as jars of food including pickles and cranberry sauce.
The collars featured the national Recycle Now artwork and told shoppers that "Recycling this bottle or jar saves enough energy to power a TV for 20 minutes."
A research team then asked shoppers how the campaign had affected their views on recycling.
About 38% of people thought that recycling was very important. And from those who did not already recycle bottles and jars, 39% said the tags had made them act or think about recycling.
British Glass director of strategy and communications Andrew Hartley said: "The campaign was designed to take the national Recycle Now and the Big Recycle campaigns down to an individual level. Getting consumers to think about recycling glass while they are shopping is a powerful addition to our efforts to change consumer attitudes to recycling.
"The initial research results indicate that it was effective in helping improve attitudes to recycling."
