Warrnambool City Council introduced a fourth glass-only bin with a purple lid to 3300 households in a trial in February.

The bins were collected each fortnight, as were the household's 240-litre waste bins.

On Monday night the council unanimously voted to give all households four bins after declaring the trial a success.

Warrnambool City Council chief executive officer Peter Schneider said between 20 and 25 tonnes of glass was being collected a month during the trial. He said more than 1200 households were regularly placing their glass-only bins out for collection.

The council also voted to keep the 600-litre bottle banks at supermarkets in Dennington, central Warrnambool and Bunnings.

Mr Schneider said the results of a survey sent to households involved in the trial showed the majority of residents supported the addition of the glass-only bin.

He said the council would commence the rollout from July, with all homes to have four bins within nine months.

Mr Schneider said more than half of the people who responded to the survey said the size of the glass-only bin was satisfactory.

However, 68 residents said they needed a bigger bin for general waste if it was going to be collected fortnightly.

Mayor Tony Herbert said he was pleased the council's FOGO food and garden waste bins and now the glass-only bins had been well received.

He said the initiatives would help the council achieve its goal of diverting 80 per cent of waste from landfill by 2026.

The glass collected will be crushed for use in concreting by local contractors and in local roads.

Councillor David Owen said he had nothing but good things to say about the fourth bin.

"How good is this council? How good is this?" he said.

Cr Owen said he knew the community would embrace an environmentally-friendly initiative.

"I had 100 per cent faith in the community that they want to do the right thing," he said.

Cr Owen said other councils across the state were considering following Warrnambool's lead by introducing glass-only bins.

"This really shows how aspirational we are," he said.

Other feedback received included a few people who believed four bins was too many, a few others commented about the noise on bin night due to glass-only bins, while others also called for the introduction of a container deposit scheme.

Cr Neoh said he supported that idea, saying people should be able to get a refund for glass and cans.
