ZALF PhD student at the ACLCA 2023 conference in Burlington (USA)

The American Center for Life Cycle Assessment (ACLCA) held its annual conference from September 25-28 in Burlington, USA. More than 200 speakers presented their research on life-cycle analysis in a variety of sectors. ​

René Méité, PhD student in the BMBF junior research group BioKum, presented the results of his study on the environmental impacts of three innovative emission abatement measures in dairy farming, namely the additional feeding of the seaweed Asparagopsis, the separation of urine and faeces by a cow toilet, and the acidification of slurry during application on forage fields. ​

The results show that the three practices can reduce environmental impacts with a different effectiveness, yet, may involve trade-offs between different environmental impact categories, for example, between global warming potential and abiotic depletion. Trade-offs can be partially compensated if the three measures are implemented together.​

Trade-offs and interactions should therefore be taken into account when promoting abatement measures in regulations and funding programs in order to further improve the overall environmental impact of emission reduction measures.​
