A Comprehensive Guide to Inventory Analysis in Life Cycle Assessment

Inventory Analysis, an integral part of the Life Cycle Assessment (LCA), can be seen as the foundation that supports all the subsequent stages of an LCA. Let’s deep dive into the intricate process of Inventory Analysis, its constituents, and its significance.

Constructing a Process Flow Chart

A process flow chart is the roadmap that elucidates every process, flow, and pathway that a product or service undergoes during its lifecycle.

• Identifying Scope of Investigation: With a process flow chart, the scope of the investigation becomes lucid. This not only helps in locating the critical processes but also illuminates the often overlooked or “hidden” flows which might hold significant environmental repercussions.

Assigning Project Boundaries

Determining the boundaries is quintessential to ascertain the scope and limitations of the analysis.

• Inclusivity in Analysis: Ideally, the boundaries should encompass every resource extraction and environmental emission pertinent to a product.

• Practical Constraints: In reality, while the goal is comprehensiveness, capturing the entire spectrum is daunting. Thus, setting boundaries ensures the analysis remains focused and manageable.

Collecting and Processing Data

The heart of Inventory Analysis lies in data. Gathering accurate, relevant data is both an art and a science.

• Time and Effort Intensity: Amassing data is an arduous task, often demanding the lion’s share of time and resources in an LCA.

• Allocation Procedures: For systems with manifold product flows, establishing allocation protocols becomes indispensable. This ensures every product flow is accounted for, and there’s no overlap or omission.

• Energy Flow Calculations: Different fuels have different environmental footprints. Therefore, computations of energy flows and resultant extractions and emissions should be fuel-specific.

Data Sources

Access to reliable data sources is the linchpin of a successful Inventory Analysis. Some renowned databases include:

• Eco-invent Database: Predominantly European data, it offers insights on a myriad of building products, energy production, and transportation. The data is often utilized via the SimaPro interface. Its US counterpart, the Franklin database, is in the pipeline.

• Athena CMI: This database, centered around Canadian data, provides substantial information on building products. The Athena Institute also offers an evaluation interface.

• BEES (NIST): While free, this North American database is circumscribed in its scope, focusing on a select few building products.

• EIOLCA (Carnegie Mellon): Another free resource, it provides aggregated North American data. However, it’s limited in its scope and transparency.

Each database has its strengths and should be chosen based on the specific needs and geographical context of the project.
