• Broiler production has slightly higher protein efficiency than egg production

• Laying hen production achieved higher single score results than broiler production

• The production of feed has by far the largest share of the environmental impact of the entire production

• Decrease of environmental impact due to introduction of larva

Optimization of Hermetia Illucens diet  2. Valorization of agronomic potential of the frass  3. Finding out the optimal level of Hermetia Illucens larvae in chicken diet  4. Larval influence on the bird welfare status  5. The impact of larvae bioactive compounds on chicken gut  6. Larval influence on poultry meat quality  7. The environmental impact of the chicken meat  3 6/24/2022 Dusan Ristic - Food Data Group, DIL POULTRYNSECT – PROJECT OVERVIEW • Protein of animal origin – high environmental costs  • Higher efficiency:   1) less resources used and/or  2)   more protein   • Can we use insects to minimize the use of resources?  • How can we get the most protein from chicken production? 4 SOY OR INSECTS? CHICKEN OR EGGS? 6/24/2022 Dusan Ristic - Food Data Group, DIL Picture source: https://ecochain.com/knowledge/life-cycle-assessment-lca-guide/ 5 LCA STAGES 6/24/2022 Dusan Ristic - Food Data Group, DIL • Environmental impact and efficiency of 2 types of chicken protein production  • Estimate the amount of protein produced from feed providing 20t of protein  • Further, it was hypothesized that environmental footprint of protein production can be lowered by inclusion of insects into the commercial feed  • Insects were considered to be fed on 2 different diets 6 GOAL AND SCOPE 6/24/2022 Dusan Ristic - Food Data Group, DIL 7 6/24/2022 • The data were collected from the literature, mostly:  1. Dekker et al. (2011) (Netherlands) for laying hen production and 2. González-García et al. (2014) (Portugal) for broiler production)  • Calculations were done in SimaPro 8.5.2.0 (PRé Consultants, Netherlands)  • Background data were taken from the ecoinvent 3 (ecoinvent, Switzerland) and Agri-footprint (Agri-footprint, Netherlands) database.  • Adapted to the DIN EN ISO 14044:2006   8 INVENTORY ANALYSIS 6/24/2022 Dusan Ristic - Food Data Group, DIL • Methodology - IMPACT 2002+  • Two functional units:  1. Protein conversion ratio, FU1 – amount of chicken protein that can be produced with 20t of feed protein.  2. Functional unit, FU2 – estimation of production of 1 kg of chicken protein.  9 INVENTORY ANALYSIS 6/24/2022 Dusan Ristic - Food Data Group, DIL Scenarios Commercial feed protein (t) BSFL protein, fed with Gainesville diet (t) BSFL protein, fed with fruit and vegetable waste (t) Protein produced (kg) A Egg production 20     8,335.75 B Egg production 18 2   C Egg production 18   2 D Broiler production 20     9,135.456 E Broiler production 18 2   F Broiler production 18   2 10 PROTEIN PRODUCED  Protein conversion efficiency: 0.417 for laying hens and 0.446 for broilers. 6/24/2022 Dusan Ristic - Food Data Group, DIL 11 LCA RESULTS  6/24/2022 12 LCA RESULTS 6/24/2022 • Broiler production has slightly higher protein efficiency than egg production  • Laying hen production achieved higher single score results than broiler production  • The production of feed has by far the largest share of the environmental impact of the entire production  • Decrease of environmental impact due to introduction of larvae:  13 CONCLUSIONS 6/24/2022 Dusan Ristic - Food Data Group, DIL Decrease in environmental impact achieved by introduction of HI larvae into the diet of:Larvae fed on Gainesville dietLarvae fed on fruit and vegetable wasteLaying hens 5% 5.50%Broilers 3.30% 3.80%The project is supported by funds of the Federal Ministry of Food and Agriculture (BMEL) based on a decision of the parliament of the Federal Republic of Germany via the Federal Office for Agriculture and Food (BLE) under the Federal Programme for Ecological Farming and Other Forms of Sustainable Agriculture      14 ACKNOWLEDGEMENTS The authors acknowledge the financial support for this project provided by transnational funding bodies, being partners of the H2020 ERA-net project, CORE Organic Cofund, and the SUSFOOD2 cofund from the European Commission.
