The sustainability glossary helps you understand terms that are specific to sustainability.


A process whereby air pollution— mainly composed of ammonia, sulfur dioxide and nitrogen oxides—is converted into acidic substances that cause damage, e.g., to forests, lakes and buildings. Sulfur dioxide and the nitrogen oxides are mainly emitted by burning fossil fuels.

Greenhouse Gases

The Kyoto Protocol regulates the most important greenhouse gases: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and synthetic gases, such as fluorocarbons (FKW/HFC), perfluorinated hydrocarbon and sulfur hexafluoride. Fossil fuels are the main cause for the emission of CO2 and N2O.


Global Reporting Initiative, a global standard for sustainability reporting.


Giga tons

Hazardous waste

In 2009 Sulzer introduced a Sulzer list that defines 18 types of hazardous wastes. Until 2008 the sites reported hazardous wastes as it has been defined by the diverse local legislations. The treatment of a significant share of these materials could be defined as recycling (e.g., waste oil). At Sulzer, hazardous waste includes liquid and solid waste—most often used paints and solvents, used emulsions from machinery, metallic sludges, waste water from galvanic processes, and filter dusts from, e.g., sand blasting equipment.

Municipal waste

Non-hazardous waste that cannot be given to recycling, such as waste from households (e.g., tetrabriks and composite packaging). It can be treated in a waste incineration plant or disposed off in a landfill.
