The study will find out how much and what types of food are wasted in NSW households each year.
To be part of the study, households can request an EPA food waste bag online.
Once it arrives, participants are asked to clean out their fridge, putting expired food in the bag instead of putting it in the bin. The next step is to record their food waste over the next two days and log the results on the EPA’s website.
Environment Minister Gabrielle Upton said reducing food waste was a priority for the government.
“We're asking households to participate in a study to get a better read on how much food they waste every year, so we can develop programs to reduce food waste,” Ms Upton said.
“The last three years of EPA research shows one in 10 people admit they waste more food than they should.”
An EPA survey from last year estimates the average NSW household is throwing out almost $4000 of food waste each year.
