Sustainability

Our Approach to Sustainability

OMH remains steadfast in its commitment to driving growth and value creation, benefiting customers, shareholders and employees while responding to the imperative for a sustainable future. As a leading manganese and silicon company in the region, we consistently excel in economic competitiveness and environmental standards, owing to our extensive knowledge accumulation, targeted investments, and ongoing organisational development.

Stakeholder Engagement

We believe our long-term success is fundamentally linked to close collaboration with our stakeholders, including those who influence our decisions and those impacted by our operations. We maintain a proactive engagement approach to remain response to their evolving priorities. This ongoing dialogue allows us to refine our strategies and ensure the creation of shared value.

Materiality Assessment

Our materiality study identifies the environmental, social, governance, and economic factors that are most critical to OMH’s long-term success. By analysing these material aspects, we ensure well-informed decision-making and responsible resource allocation, fostering organisational resilience and aligning our sustainability initiatives with our most significant business and societal impacts.

In FY2025, OMH conducted its third materiality assessment exercise, marking a significant evolution in our reporting approach. Moving beyond our 2023 exercise, we adopted a double materiality framework to gain a holistic view of our actual and potential impacts, risks, and opportunities (IROs). This process was driven by a cross-functional team, comprising representatives from Environment, Health & Safety, Human Resources, Finance, Corporate, and Marketing & Trades. This ensured that diverse internal perspectives informed every stage of the assessment.
