The function of livestock buildings is mainly to give shelter for confined animals and protect against predators. Up to date, most buildings used for organic livestock farming are mainly constructed using concrete, steel or wood elements. Thus, negative environmental impacts have to be considered.
Annual world production of cement as one of the main building raw materials implies 4 % of annual CO2 emissions. Sustainable livestock buildings can be more environmentally friendly and
cost-efficient, if renewable raw materials of local resources and even waste materials are used.
