Caravan parks, manufactured housing units, retirement villages and aged care facilities make up the majority of expressions of interest in response to a new green bin collection program for multi-unit dwellings.

Port Macquarie-Hastings Council attributes this to the example of Garden Village's success in recycling its food waste.

The council is calling on owners, body corporates and residents to participate in the new green bin collection program for multi-unit dwellings.

Caravan parks and manufactured housing units make up 41 per cent of the responses and contacts to date, council figures show.

A council spokesperson said more than a quarter of interest received had come from owners and owners' corporations.

The council has received 62 registrations from residents living in a variety of multi-unit dwellings.

"Individuals can be confident that if they sign up and are eligible, we can talk to their body corporates to discuss the program," the council spokesperson said.

Registration is open until August 31.

The program provides an opportunity to receive one-on-one education for each multi-unit dwelling household on recycling their food waste correctly.

"It is also an opportunity as a community to increase the amount of waste we recycle into premium compost and keep food waste out of landfill, reducing the amount of methane released into our environment," the spokesperson said.

The response to the multi-unit dwelling green bin program has been positive but the council would still like to hear from more eligible residents.

Those eligible include residential apartment complexes with a strata plan, retirement villages, caravan parks with permanent residents and manufactured housing estates.

People can register their interest on the council's website.

Port Macquarie Hastings Sustainability Network member Dr Angela Frimberger said less waste to landfill, especially food waste, was always better.

She said there were no downsides to composting and the green bin system.

Food waste in landfill is a major source of methane and carbon dioxide emissions.

The project is supported by the Environmental Trust as part of the NSW Department of Planning, Industry and Environment Waste Less, Recycle More initiative funded from the waste levy.
