Waste

EN11; STEV73; §6.2 of Decalogue

In 2005, only 8.3% of total waste produced by ST went to landfill, not quite in line with our 5% target. All other waste was reused, recycled, or burned with energy valorization. The chart below shows landfill waste as a percentage of total waste over time.

1994	59.4	79.4	71
1995	45.4	59.4	51

EN2; STEV71, STEV72; §6.1 of Decalogue

In 2005 we recycled or reused 78% of our waste.

EN2; STEV71: Recycled waste					%
	1994	2002	2003	2004	2005
Waste recycled	25	65	73	80	78

We are still some way from our target of 95% waste recycled or reused. In 2004, we reused or recycled 32,000 of the 41,000 tons of waste generated.

Hazardous waste

Hazardous waste, in very general terms, is the waste resulting from the production process, which can include chemical substances, plastics, lightbulbs, etc. The formal definition of hazardous waste varies from country to country. Since 2004, we have been tracking data on hazardous waste, but these data are not yet ready for publication.

All hazardous waste is disposed of safely by specially authorized companies to avoid environmental contamination (e.g. solvents are burned with energy recovery; inorganic substances can be reused inside or outside ST).
