Mr. William TAN

With 18 years of experience across Sustainability Management, Engineering, and Business Development, I have built a strong track record of delivering impactful, future‑focused environmental strategies within the Pharmaceutical, Engineering, and Biotechnology sectors. As Sustainability Manager at GSK, I lead the site’s transformation toward net‑zero carbon operations and net‑positive environmental outcomes, implementing initiatives that significantly elevate energy performance, resource efficiency, and circularity.
In my role, I have driven the transition to 100% renewable electricity, expanded on‑site solar generation, and modernized critical utilities to achieve substantial reductions in carbon emissions. These initiatives have strengthened the site’s long‑term resilience while advancing corporate climate commitments.
My waste and circularity programs have increased overall material recovery, reduced hazardous waste generation, and enabled innovative reuse pathways that support a more regenerative operating model. Complementing this, I have led major water efficiency efforts that significantly improve recycling and recovery rates across operations.
Beyond resource efficiency, I championed biodiversity enhancement projects that delivered a net‑positive ecological impact, positioning the site as a model for integrated nature stewardship within industrial environments.
Throughout my career, I have excelled in project leadership, digital transformation, operations optimization, and stakeholder collaboration—consistently delivering sustainable solutions that are scalable, measurable, and aligned with global climate and nature goals.
