O-I has invested approximately $6 million (USD) in glass recycling around the world in the last three years.

Speaking on Global Recycling Day earlier this month, it said in Brazil it supports a campaign which collects glass from bars and restaurants and delivers it to O-I for reprocessing and manufacture into new packaging.

In France, it links how much glass it recycles to charity – in 2018, O-I donated €90,000 to fight cancer.

The company is working on technology to increase levels of recycled glass in all products, particularly amber and clear glass which historically have used less cullet than green bottles.
