At the beginning of 2021, we received support from an EU project called “Green Circular Transformation”.
The purpose of the project was to measure the CO2 footprint of our products.
Skilled consultants have helped us analyze our consumption of resources by calculating the CO2 footprint of our stocks. Subsequently, we have had the opportunity to compare the CO2 footprint of our stocks with similar traditionally produced stocks.
It was very interesting!
Through this report, we will explain our choices of the raw materials, as well as interesting information about our packaging.
1. Our stocks have a lower CO2 footprint*
One thing is that we reduce food waste from the industry by using surplus raw materials - but our stocks also have a lower impact on the environment compared to traditionally produced stocks.
Let’s zoom in on our chicken stock.
The chart below illustrates the comparison between our chicken stock and a traditionally produced chicken stock. It is clear that it is in the agricultural phase that the two products differ from each other, where transport, the production itself and the packaging more or less together have the same climate footprints.
The biggest difference is seen in the agricultural phase and the reason for this is that the chicken used for traditionally produced stocks only have one purpose, where we use egg-laying chickens that else were wasted. Therefore our CO2 footprints are much lower.
2. Oarweed are CO2 neutral
We have used oarweed in our vegetable stock because it gives a fantastic taste. The choice is also based on the fact that oarweed is sustainable in several areas including health and food. We buy our oarweed from Nordisk Tang, which gently harvests the oarweed under controlled conditions.
Oarweed is particularly sustainable because it absorbs CO2 during its growth phase. Oarweed absorbs nutrients and sunlight through all the plant’s cells and therefore is the process extremely fast - faster than trees on land absorbs CO2.
These factors together are the reason why our vegetable stock is the product with the lowest CO2 footprint. It emits only 0.18 kg CO2e per stock.
3. Our seafood stock has a positive effect on the fjord's edible fish and a low CO2 footprint*
Our shellfish stock emits 3 times less CO2 than a traditionally produced shellfish stock. This result considers indirect changes in the use of land and the processing of raw materials (ILUC). In 2005, The Technical University of Denmark launched a pilot project with the purpose of investigating beach crabs as raw materials for stock production. The project defined the use of beach crabs to production as a sustainable choice, as the number of crabs can still be maintained at the desired level and still be able to reproduce with the given fishing exploitation.
This product differs from our other stocks as the main ingredients in the other stocks are surplus materials from the industry where beach crabs are seen as problems for fish and the fishing industry. According to Bælternes Fiskeriforening and AqueaMind (2019), beach crabs are serious competition for valuable species such as eels, tongues, plaice and flounder, and they also make problems for ruse fishing as they damage the fish.
These problems together with the decrease in fishing over the last 7 years, could indicate that the beach crabs have a negative impact on the fjord's production of edible fish. Likewise, this is analyzed to be a problem for commercial fishing.
4. We need to optimize our packaging
By analyzing our consumption of resources, we discovered our packaging to be the parameter that has the largest CO2 footprint in production. At the moment we use glass containers and aluminium lids.
Eventually, this is something we need to find a new solution to, as our vision is to make stocks with the lowest CO2 footprint possible.
Explanation & background
Green Circular Transformation: reporting the CO2 footprint of Reduced stocks'
The surplus raw materials such as egg-laying hens, vegetables and veal calf bones are calculated on the basis of an alternative utilization process, in the form of sending the organic waste to a biogas plant. It constitutes the climate footprint of the raw material, since it has avoided processing biogas from raw materials but instead is used as food.
Beach crabs are calculated based on the impact it has on fishing them up, as bycatch of fishing. This climate footprint considers agriculture, indirect change in the use of land (ILUC) and beach crab processing.
Each type of stock has been compared with a traditional stock production, where for example the meat-containing raw materials came from ordinary production. These climate footprints consider agriculture, indirect change in the use of land (ILUC) and processing of raw material.
Pilot project for the development of beach crab fisheries for feed production (2005)
Since 2002, the Technical University of Denmark has carried out a number of research and development projects with the purpose of utilizing beach crabs, partly for human consumption and partly for animal feed.
The conclusions presented in this report are based on DTU’s Pilot Project from 2005. Prepared by Knud Fischer, Ole S. Rasmussen, Niels F. Johansen, Ulrik Cold and Bo M. Jørgensen.
The project was funded by the Ministry of Food, Agriculture and Fisheries and the European Fisheries Fund: "Denmark and Europe invest in sustainable fisheries and aquaculture"
Report about beach crabs: Profitable use of by-products - Beach crabs, (2019).
Beach crabs are a major and growing problem for fishing in inland Danish waters, and Allan Buch, chairman of the Belt Fisheries Association of the University of Copenhagen, has investigated this problem in collaboration with AquaMind. The report examines the possibility of a profitable sorting and handling of beach crabs and other unwanted catches.
Information about seaweed
The information about the seaweeds growth phase and its CO2 footprint comes from Dansk Tang and Nordisk Tang.
