Consumers are less likely to recycle if they need to separate the packaging materials

Have you ever stood there with empty food packaging and wondered how you're actually supposed to sort it for recycling? You're not alone.

People often sort their waste to contribute to a better environment. The task isn't always easy when the packaging is made from several different materials.

Packaging ensures durable, safe, and appetising food.

What happens if the packaging changes? Will consumers still buy the same product packaged in a more sustainable material – which also requires a bit of effort to separate?

This is what the researchers in the ReFiberPack project wanted to find out.

“We want to learn more about Norwegian consumers’ attitudes and habits regarding source separation, food packaging, and acceptance of new packaging solutions,” says Mads Erling Pedersen, a senior engineer at Nofima.

A nationwide survey showed a positive change in attitudes towards waste sorting over the last 25 years.

People want to consider the environment. We appreciate being able to contribute by making an effort at home.

Positive, but not to everything

Participants said that food safety was the most important aspect of food packaging. Then comes shelf life and environmental friendliness.

Most were positive towards new types of food packaging that may be better for the environment.

Environmental considerations and waste sorting were important to the participants. Nevertheless, they were sceptical of new packaging that required an effort to separate plastic from cardboard before sorting. 

Different packaging solutions

Participants were also asked about various packaging solutions based on combinations of cardboard and plastic materials, with or without recycled content. 

Each solution was rated on a scale from one to seven according to the following criteria:

  • Likelihood that the packaging would be sorted for recycling
  • User-friendliness
  • Environmental friendliness
  • Food safety
  • Shelf life
  • Sensory quality (how the food is perceived with the senses, such as taste, smell, texture, and appearance)

Researcher Valérie Lengard Almli believes that over time, people will gain confidence in the new solutions.

People don't want extra work

The results are clear: If recycling requires extra work, such as separating different materials in the packaging, it's more likely that consumers will choose not to recycle.

“In the project, we're also working on solutions where the industry can manage the necessary separation for material recycling. Consumers were much more positive towards such industrial solutions,” says Valérie Lengard Almli, a senior scientist at Nofima.

Participants said that packaging made of fibre-based material with less plastic is better for the environment. They also perceived such packaging to be be worse for food safety, shelf life, and sensory quality (taste, smell, and appearance).

Counteracting scepticism

“The results are not what we had hoped for, but this is vital information for both packaging and food producers,” says Almli.

Food producers have in any case received new regulations that require changes. They are required to use environmentally friendly and recyclable packaging solutions.

When consumers discover that the new solutions are just as safe and effective as the old ones, trust will follow, Almli believes.

The researchers will now further investigate how best to reduce scepticism and motivate more people to engage in source separation.

About the research

The research is funded by the Research Council of Norway through the ReFiberPack project – Recyclable food packaging based on recycled cellulose and removable barriers.

The aim is to develop new and recyclable food packaging based on recycled cellulose fibres and removable barriers, so that these two components can be sorted separately and recycled. In this way, the food and packaging industries can both meet new environmental requirements and make it easier for consumers to contribute in practice.
