Hazardous Waste
Hazardous Materials Facility offers a comprehensive hazardous waste disposal service for all wastes including biohazard waste, chemical waste and lab smalls (LabCup). Each area is charged for the service based on the amount disposed and all hazardous waste is consigned to authorized facilities only for treatment or disposal.
Approximately 50 tonnes of hazardous waste is produced by laboratories in Trinity each year. All of this is tracked by HMF until final destruction in Irish and European facilities.
The disposal of hazardous waste is controlled by a number of regulatory provisions and producers of hazardous waste are legally responsible for complying with these requirements.

Is my waste hazardous?
Waste is considered hazardous when it meets the prescribed characteristics detailed below. The hazard statement codes may be found in Section 2 of the safety data sheet (SDS) for the substance.
HP1 Explosive
Waste which is capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic waste, explosive organic peroxide waste and explosive self-reactive waste is included. When a waste contains one or more substances classified by one of the hazard class and category codes and hazard statement codes shown in Table 1, the waste shall be assessed for HP 1, where appropriate and proportionate, according to test methods. If the presence of a substance, a mixture or an article indicates that the waste is explosive, it shall be classified as hazardous by HP 1.
