Summary: This study evaluated the environmental impact and energy consumption associated with the production of protein hydrolysates used as plant biostimulants. The research compared two different production methods: enzymatic hydrolysis of legume-derived proteins (specifically lupine seeds) and chemical hydrolysis of animal-derived proteins (from leather waste). The analysis was conducted using the Life Cycle Assessment (LCA) method with the GEMIS software, focusing on three main parameters: CO2 emissions, fossil energy consumption, and water use per kilogram of protein hydrolysate produced. Enzymatic hydrolysis of legume-derived proteins, such as lupine, is a more environmentally sustainable method for producing protein hydrolysates compared to chemical hydrolysis of animal-derived proteins. This process results in lower CO2 emissions, reduced fossil energy consumption, and decreased water usage, making it a more eco-friendly alternative for producing plant biostimulants.
