Assessing Environmental and Economic Sustainability: Valorizing Grape Stems for Animal Feed Production.

ABSTRACT: This study evaluated an innovative strategy for valorizing grape stems (GS) from the winery industry as an animal feed ingredient from both environmental life-cycle and economic perspectives. Two processes for GS-based feed ingredient production were compared: one using hydrolyzed GS and the other using nonhydrolyzed GS, alongside the conventional animal feed production process. Using primary pilot-scale data for GS-based feed ingredient production and secondary data for animal feed production, life-cycle assessments, and economic analyses were conducted. Results showed that hydrolyzing GS leads to 3.8 times higher impacts on human health compared to the nonhydrolyzed variant, primarily due to NaOH and electricity usage, although this difference becomes negligible at the animal feed produc
