USA – GM’s Rayong engine plant in Thailand and its Cheongna proving ground in South Korea are now landfill-free, says the company. This brings the total to 33 sites throughout Asia that recycle, reuse or convert to energy all of their daily waste, says GM.

Waste-reduction best practices range from hi-tech processes to minimise sludge from wastewater treatment, painting or grinding, to locally sourcing and sanitising gloves for reuse. The latter reduced waste at the Talegaon plant 10 tons in one year alone, says GM.

The Cheongna proving ground in Incheon is recycling materials required for vehicle development and research, including batteries, plastic, chassis components, packaging and chemicals.
