Livestock feed production
(produktion af dyrefoder)


Livestock feed pellets are produced industrially by mixing and pressing a variety of ingredients.

Process description

The present data refer to livestock feed production in DLG Fabrik Aalborg (DLG) in 2001 where the main production processes are following: 1) Ingredient such as corn, soy meal, rape seed are received and stored 2) the ingredients are mixed and crushed 3) the mixture is pressed into pellets while steam is added, 4) the pellets are dried and cooled and stored for distribution. Products are distributed to farmers in trucks and no packaging is applied. No wastewater is generated during the production process.

Data collection and treatment

The factory produces a variety of feed products with different recipe, but since the environmental exchanges are mostly determined by the mass of the product, one general dataset for all products has been established based on the factory's green account (2001).

Technical scope

All production processes from receipt of ingredients to storage of the final product as well as administration are included.


DLG has a large share of the Danish livestock feed market and DLG fabrik Aalborg has a large share of the production in the DLG group.


Exchanges associated with feed production vary in DLG's feed factories, but all are in the same order of magnitude as recorded in DLG Fabrik Aalborg.
