Liquid waste refers to waste produced from various activities that involve the use of liquids. Such waste can alter aquatic ecosystems due to the presence of environmentally harmful chemical substances. This problem can be mitigated by treating liquid waste before it is released into the environment. To minimize the negative impact of liquid waste on aquatic ecosystems, Sriwijaya University (UNSRI) has implemented a liquid waste treatment process prior to discharge. Part of the treated wastewater is also reused for plant irrigation. Additionally, UNSRI collaborates with PT Biuteknika Bina Prima for the transportation and disposal of hazardous and toxic liquid waste. Through these initiatives, UNSRI aims to reduce ecological disturbances caused by chemical and biological contaminants.
