Classification of the waste at the workplace

Chemical wastes as well as the glass and plastic packagings gathered at the workplace have to be periodically passed on the central chemical storehouse and then transferred from there to a specialized off-site facility for recovery and disposal.

Some fraction of the generated waste belongs to the dangerous wastes therefore all the generated wastes are treated with special care as dangerous wastes or potentially dangerous wastes and are handled in accordance with the instructions drawn up for the dangerous wastes.

As a dangerous substance is regarded each single substance or each mixture of substances that due to its chemical, biological or radioactive properties if unproperly handled may cause a hazard to health or life of humans or may lead to environmental pollution; the dangerous substance may be a raw material, product, intermediate product, waste and a substance that came into existence as a result of breakdown of a particular device or equipment.

Municipal wastes, i.e. waste paper, packagings made from glass and plastics, metal scrap and discarded equipment except the waste mercury being a part of it are not rated among chemical wastes.

According to Art. 10 and Art. 17 of the Act on packagings and packaging waste of 11 May 2001: “A user of the dangerous chemical substances is obliged to return to a seller the remaining multiple-use packagings and packaging waste”.
