New cod packaging with reduced climate footprint

When the cod is packaged in Vesterålen in new packaging, it saves the climate. New products reduce greenhouse gas emissions by 30 per cent.

“It is already known that wild-caught whitefish have an average environmental impact that is significantly lower than meat,” says Nofima senior scientist Anlaug Ådland Hansen. She has been working on a new concept that reduces the environmental impact of wild fish even more. Now it is approaching the environmental figures from wheat flour and other foods that are based on plants.

Packaging and transport

Initially, the partners behind the SupremeFilet project found packaging that is both smaller and more environmentally friendly. In the past, meat and fish have mostly been packaged in plastic that is composed of several layers of different types of plastic materials. The packaging has now been replaced with recyclable plastic. It essentially consists of only one type of plastic material, so it can be melted down and reused.

The next thing that helps the climate is less transportation. Together, these measures have reduced the climate impact by 30 percent. “The new product concept has contributed to lower greenhouse gas emissions per kilo of product,” says Anlaug Ådland Hansen.

Figures lead to improvement

The researchers have compared the figures both with previous figures from Gunnar Klo, the Vesterål company that has processed and packed the fish in the project, and with other analyses that Norsus, the Norwegian Institute for Sustainability Research, has done previously.

“We need numbers to make improvements. If we can’t measure, we can’t improve,” says Hansen.

Everything in one place

Much of the improvement is about everything being done in one place. “They pack and process once,” says senior researcher Erik Svanes at Norsus.

Then there will be a difference compared to if the fish were to be received in one place and processed somewhere else in Norway or Europe. “This concept saves the environment for both packaging and transport,” explains Svanes.

Moreover, shelf life is better taken care of with the new product concept. “But we haven’t been able to calculate the environmental effect of that, because we don’t have figures on waste in people’s homes before and after. Presumably there’s less wastage, too,” he said. “It is also important that it is not only the climate impact that has been reduced, but also a wide range of other emissions – as well as the consumption of resources such as oil.

It’s not just about getting numbers that confirm common sense, says Svanes. It’s not hard to understand that less packaging and less transport are good:

“But it’s important to find out how much improvement each measure has provided. This can help the rest of the seafood industry to make similar improvements.

Checked cod

“In general, we can say that here they have come down in terms of environmental impact almost as far as it is possible to get with today’s technology,” he says. “We have analysed a product from skrei, found that it has little negative impact on the environment and found out how it has managed to get so far down.

The greenhouse gas emissions from this product are about 30 per cent lower than for the average cod on the market. Compared to the average pork and chicken, they are around 55 percent lower. At the same time, Erik Svanes emphasises that the use of resources and emissions other than greenhouse gases is also considerably lower.

“Improvements have been made in the processing, packaging material, transport and distribution to the consumer. Waste treatment is also improved, because less packaging and recyclable packaging leads to lower environmental impact. The discoveries we have made and the knowledge we have gained in this project show that it is right to invest in local processing of Norwegian fish raw materials,” says Anlaug Ådland Hansen.

Facts about the research and the project SupremeFilet

The SupremeFilet project aims to create more attractive whitefish products with a low environmental footprint.

Gunnar Klo AS owns the project, while Nofima has led the research. In addition, Fresh PL, Südpack, Multivac, Oda and Norsus are participating. The project is funded by the Research Council of Norway.

The packaging material tested in the project consists mainly of polypropylene. Together with a thin barrier layer, it provides both good preservation of quality and can be recycled for use in new packaging materials.
