This report summarizes the results for the BroilerNet WP 2 “Environmental Sustainability”. The three priority challenges that were identified by the National Level BroilerNet Innovation Network (BIN) groups of each participating country were “Improving water saving and management”, “Improving manure and farm waste management”, and “Assessing and minimizing the environmental footprint of meat from slow growing strains”. The BINs proposed in total 33 Good Practices (GP) as innovative best practice solutions to the identified challenges. Those GPs were evaluated by the Thematic Expert Network (TEN) with the use of the Good Practice Evaluation Tool (GPET). This evaluation resulted in a Top 10 of GPs for each challenge, out of which the TEN selected a Top 5 of Best Practices (BP) based on the technical quality, impact, and probability of success of a GP. For each challenge, one BP was awarded as BroilerNet Champion. The BroilerNet Champions were “EKORAINULTRA: Rainwater collection and treatment for drinking and washing purposes”, “Heat exchanger Earny2“, and “Agroforestry: planting trees, hedges and promoting meadows to capture carbon and enhance biodiversity”. In addition, a literature review was conducted with regard to the three challenges, which is also briefly described in this report.
