Life Cycle Inventory (LCI) Explained | Inputs, Outputs & Technosphere in SimaPro | LCA Tutorial

In this tutorial, we explore the theoretical concept of Life Cycle Inventory (LCI) and its critical role in Life Cycle Assessment (LCA) using SimaPro software. Life Cycle Inventory is one of the most important phases of LCA where all material, energy inputs and environmental outputs associated with a process are collected and quantified. This video explains what Life Cycle Inventory means, why it is important, and how inventory data is structured inside SimaPro. You will learn how inputs from nature, inputs from the technosphere, outputs to the technosphere, and outputs to the environment are defined in an LCA model. We also discuss how LCI connects the real laboratory process with environmental impact calculations, allowing researchers to evaluate sustainability of materials, processes, and systems. In this tutorial you will learn: • What Life Cycle Inventory (LCI) is • The relationship between LCI and Life Cycle Assessment (LCA) • How SimaPro organizes inventory data • Understanding Input from Nature (water, minerals, resources) • Understanding Input from Technosphere (electricity, chemicals, materials) • Understanding Output to Technosphere (products or intermediate materials) • Understanding Output to Nature (emissions to air, water, soil) • How Gate-to-Gate system boundaries are defined in LCA • How real experimental processes such as washing, drying, grinding, and synthesis are translated into LCI data. This video is particularly useful for researchers, PhD students, and engineers working on environmental engineering, water treatment, adsorption materials, biochar, nanomaterials, and sustainable process design. Understanding Life Cycle Inventory allows researchers to accurately quantify environmental impacts and build reliable sustainability models for scientific publications and industrial applications. 🔖 Hashtags #LifeCycleAssessment #LifeCycleInventory #LCI #LCA #SimaPro #EnvironmentalEngineering #Sustainability #GateToGate #CradleToGate #CradleToGrave #CarbonFootprint #EnvironmentalImpact #ResearchTutorial #WaterTreatment #SustainableEngineering
