Biogas digestate obtained from beef slaughter wastes and by-products are upgraded into an organic nitrogen and phosphorus (NP) fertilizer. The project explores conditions of thermal treatment processes. The effect of the new NP fertilizer on soil nutrition status and plant growth is determined in order to utilise it safely and productively in agriculture. The project supports the slaughtering industry in the transition to a fully circular approach regarding the main by-products and organic wastes resulting from its activities.

This project aims at reducing the use of chemical fertilizers in agriculture. The carbon footprint related to beef production is reduced, e.g. by improving the energy recovery rate of the involved buildings and installations, enhancing the acceptance of agro-industrial beef production systems by citizens and authorities. The project improves recycling of agro food waste using a biogas based model that is applicable in different communities and regions. The activity represents an important step in the transition to a fully circular system, increasing the sustainability of the whole beef supply chain.
