WASTE WATER: PRODUCTION
No waste is shipped internationally, and all hazardous waste is collected by a registered
waste disposal company. In FY’06 a total of 2,120 tons of hazardous waste were disposed
of. This decreased to 1,844 tons in FY’07. The hazardous waste is taken to registered
disposal sites.
In 2007, Toyota launched an Internal Recycling Project at its marketing offices in
Sandton, Johannesburg in which staff were encouraged to start sorting waste and
recycling at home, and to bring the resultant recyclable waste to the office. Since the
launch of the ‘Waste from Home’ campaign, employee recyclable waste contributions
average around 200kg per week.

Our waste recovery efforts do not only focus on materials. In the Paint Line, hot gas
from the burners gets captured and sent back to the ovens. This recirculation of hot air
significantly reduces energy consumption in the Paint Line.
We also concentrate on reducing water use through recycling of waste water. From
2006 to 2007, waste water from the TSM Main Waste Water Treatment Plant reduced
by 11% (from 3.21 kl/u to 2.87 kl/u).
In 2006, the waste water treatment plant was upgraded and capacity was increased to
accommodate the increased production arising from Paint Line 3. The upgrade was in
order to achieve the waste water quality requirements set by the municipality, and the
treatment plant was designed to meet 50% better than legal requirements. The waste
water treatment plant has a maximum output capacity of 120m 3 per hour, and currently
runs at an average of 60% of its capacity.
Water
In South Africa, the 30 th driest country in the world, reducing water consumption is key
to Toyota South Africa’s sustainability.We draw water from the eThekwini municipality
that supplies more than three million people. Following the increase in consumption
due to the introduction of Paint Line 3, our water use has started to decline again.
Our water usage and waste water increased in FY’06 because we were running two
paint lines. This impacted on consumption per unit which has stabilised since the close
of Paint Line 2.
