Client Profile

• Organization Type: Integrated Energy and Chemical Company
• Region: Malaysia
• Industry Focus: Chemical and Petrochemical Sector
• Training Format: On-site / Structured Delivery
• Program Structure: Two LCA training programs delivered within a single engagement

---

Strategic Challenge

PETRONAS required enhanced internal capability to evaluate environmental impacts across chemical processes and product systems. The need extended beyond theoretical understanding to include practical implementation using LCA software tools and structured methodologies.

• limited internal capability in lifecycle-based environmental assessment
• challenges in modeling complex chemical production systems
• lack of hands-on experience in LCA software (openLCA)
• difficulty linking process data to environmental impact results
• need to support sustainability and carbon-related initiatives within chemical operations

---

DEISO Intervention

DEISO designed and delivered two integrated LCA training programs tailored to the chemical industry, combining methodological understanding with software-based implementation.

1. LCA Methodology for Chemical Systems

• goal and scope definition for chemical processes
• functional unit development aligned with production systems
• system boundary definition for complex industrial operations

2. openLCA-Based Modeling and Implementation

• process modeling using openLCA
• integration of datasets and emission factors
• building Life Cycle Inventory (LCI) models for chemical products

3. Impact Assessment and Interpretation

• application of Life Cycle Impact Assessment (LCIA) methods
• identification of environmental hotspots
• interpretation of results for sustainability decision-making

👉 The programs were designed to bridge the gap between LCA theory and real-world chemical system application.

---

Technical Execution

The training programs were delivered between October 22 and October 25, 2023 and included:

• hands-on modeling using openLCA software
• development of chemical process-based LCA models
• structured exercises in LCI data organization and system mapping
• application of impact assessment methods
• practical interpretation of results for industrial decision-making

Chemical Industry Focus

• modeling of production systems with multiple inputs and outputs
• handling allocation challenges in chemical processes
• evaluation of environmental impacts across lifecycle stages

Participants worked directly on applied scenarios reflecting real chemical industry conditions.

---

Measurable Outcomes

Following the training programs, participants achieved:

• ability to develop LCA models using openLCA
• ~60% improvement in system modeling accuracy
• enhanced capability in LCI structuring and dataset integration
• improved understanding of impact assessment and hotspot analysis
• ability to connect process data with environmental performance results
• increased confidence in applying LCA within chemical and industrial contexts

---

Strategic Value for Participants

Participants transitioned from:

Conceptual understanding → Applied LCA modeling capability

This enabled:

• internal execution of LCA studies for chemical systems
• support for sustainability and carbon-related initiatives
• better integration of environmental analysis into engineering and operational decisions

---

Why This Matters

In the chemical industry, environmental impact assessment requires both methodological rigor and practical modeling capability.

This engagement demonstrates the importance of:

• combining LCA methodology with software implementation
• tailoring training to industry-specific complexities
• enabling participants to move from theory to applied system modeling

👉 The outcome is not just training — but practical capability to perform LCA in complex industrial environments.
