Toxic Emissions & Waste
TNB’S SF6 GAS RECYCLING AND RECONDITIONING
CENTRE AN INITIATIVE FOR SUSTAINABILITY
TNB Grid’s SF6 Gas Recycling and Reconditioning Centre, a trailblazer in Southeast
Asia’s environmental efforts, redefines SF6 gas management. SF6, a potent
greenhouse gas crucial for insulating electrical equipment like Gas Insulated
Switchgear (GIS) and Circuit Breakers (CBs), poses a significant environmental
challenge. With the highest Global Warming Potential (GWP) of approximately 23,500
and an atmospheric lifetime of around 3,200 years, SF6 necessitates a solution to
reduce reliance on virgin gas and minimise its environmental impact.
Our rising SF6 consumption and the high cost of returning waste to its origin
countries for incineration further emphasise the need for a solution. Incineration, the
most common method, raises concerns due to potential greenhouse gas emissions
during the process. Returning waste to origin countries like Germany, South Korea, and
Australia is expensive, costing RM11.6/kg with an additional surcharge of RM232
for every 40kg bottle. Launched in October 2021, the centre tackles this challenge
head-on, minimising environmental impact by embracing a circular economy approach
and paving the way for a more sustainable future.
