The environmental burden in air and water in Germany is surveyed. The terms 'eco-unobjectionable technology' and 'disposal technology' are then considered with the aid of examples. These are fundamental chemical engineering approaches for reducing or eliminating environmental burdens due to industrial production processes. 'Eco-unobjectionable processes' are those in which undesired pollutants are not even formed, i.e. when possible emissions are eliminated at source. If this is only partly possible, or impossible, then disposal measures are adopted. This means removal of unavoidable pollutants from waste gases and waste water, and the disposal of other wastes.
