record, track and report scheduled waste generated by TNB operations in the Electronic Scheduled Waste Information System. In 2023, scheduled waste was further categorised as “diverted from disposal” and “directed to disposal”. This categorisation helps us to understand our waste usage patterns to enable informed waste reduction strategies. The Electronic Waste Inventory System was introduced in 2023 as a tool to record, track and report electronic waste generated from TNB offices for a more holistic monitoring of e-waste management. Non-Hazardous Waste Our management of non-hazardous waste is regulated by the Jabatan Pengurusan Sisa Pepejal Negara and governed by the Solid Waste and Public Cleansing Management Act 2007 (Act 672). We are taking a phased approach towards improving our non-hazardous waste management. In 2023, the Tenaga Solid Waste Inventory (TESWI)was established to kick-start our non-hazardous waste data collection. TESWI enables business operations to collect data and monitor solid waste generation to promote waste separation and encourage recycling practices.
