Hasanuddin University (UNHAS) has a formal policy, a defined process, and documented practice for disposing of hazardous and toxic (Bahan Berbahaya dan Beracun, B3) waste, from segregation at source to treatment by licensed operators. The commitment is set out in the following policies, all of which remain in force:
19.
Rector’s Decree No. 04061/UN4.1/KEP/2024 on Guidelines for Efficient and Sustainable Wastewater Management, issued on 16 April 2024, whose hazardous waste section sets six principles (legal compliance, prevention at source, inter-unit coordination, transparency and accountability, occupational health and safety, and sustainable use). It assigns clear roles: the Rector sets policy and reports to the authorities; the Vice Rector for Research coordinates and monitors compliance; deans appoint faculty B3 officers; a university B3 coordinator manages records, storage, and reporting; and laboratory staff apply standard operating procedures for segregation, labelling, packaging, and personal protective equipment. External transport must use licensed companies with a manifest, treatment and disposal may only go through licensed partners, faculties report quarterly, an internal audit is held at least once a year, and the guidelines are reviewed at least every two years.
21.
Rector’s Regulation No. 9/UN4.1/2025 on Strategic Policy for Waste Management at Hasanuddin University, enacted on 15 April 2025. It requires waste to be sorted into organic, inorganic, and hazardous waste before disposal (Article 11(2)), classifies waste containing B3 as specific waste requiring special management (Articles 1(9) and 12(1)(c)), requires any use of B3 waste to comply with national regulations (Article 13(3)), and sets up a campus waste management task force to supervise and evaluate implementation, with a published annual report (Article 17).
These policies follow the national rules on hazardous and toxic waste, now set by Government Regulation No. 22/2021 and Minister of Environment and Forestry Regulation No. 6/2021 on procedures and requirements for managing hazardous and toxic waste.
Beyond formal policy, UNHAS implements this framework through a traceable chain of practice:
22. Segregation and pre-treatment: faculty standard operating procedures (Engineering, Nursing, Public Health, and Mathematics and Natural Sciences) guide the identification and segregation of waste at source into labelled containers for liquid, solid, medical, sharps, laboratory, and electronic waste. Infectious waste from the RISE laboratory of the Faculty of Public Health is autoclaved before storage, and each cycle is logged.
23. Storage and records: B3 waste is held in temporary storage facilities at UNHAS Hospital and at the Faculties of Medicine, Nursing, Engineering, Marine Science and Fisheries, Mathematics and Natural Sciences, and Pharmacy. Every movement is recorded in a B3 logbook.
24. Licensed transport and manifests: licensed companies, including PT Maloga Prima Rezeki and PT Celebes Citra Pratama, collect the waste under agreements with the university and faculties, using manifests that trace each load from source to treatment facility.
25. Measured results: in 2025, 10.64 tonnes of B3 waste were handed to licensed operators: 9.54 tonnes of laboratory chemicals, 0.79 tonnes of contaminated solid waste, and 0.31 tonnes of electronic waste.
Through these policies, defined roles, standard operating procedures, licensed partners, and manifests, UNHAS keeps hazardous materials out of soil, water, and general waste streams to protect human health and the environment.
