Design and implementation decisions are then adapted according to these findings.
The Tuzla Tepeören Campus has an open-space ratio of 65.91% and a planted vegetation ratio of 47.34%. These are key indicators supporting the continuity of green spaces in campus planning processes. The natural pond, planted areas, and habitat features are protected. New developments prioritise local species, permeable surfaces, rainwater management, and the maintenance of ecological connectivity.
Biodiversity and Ecosystems Protection Policy
SDG 15.3.4 Policy on Reducing the Impact of Alien Species
Using the IUCN definition of alien species as a reference, Istanbul Okan University aims to reduce the impact of alien and invasive species on local ecosystems across the campus. Native or ecologically appropriate species are prioritised in landscaping and maintenance processes. Newly introduced plant species are assessed for potential risks, and species with the potential to spread are monitored.
When a suspected alien or invasive species is identified, its identification is verified, its distribution area is recorded, and mechanical, biological, or other appropriate control methods are assessed. Ensuring that interventions do not harm native species and monitoring their outcomes are fundamental principles. Members of the University community are involved in the process through reporting and awareness-raising activities.
Biodiversity and Ecosystems Protection Policy
SDG 15.3.5 Collaboration for Shared Land Ecosystems

SDG 15.4 Land-Sensitive Waste Disposal
SDG 15.4.1 Water Discharge Guidelines and Standards
Istanbul Okan University applies water quality and wastewater management standards to prevent the adverse effects of water discharges on surface water, groundwater, terrestrial ecosystems, wildlife, and human health. These efforts are supported by the Sustainable Water Policy dated 5 June 2024, the Policy for the Conservation and Sustainable Use of Biodiversity and Ecosystems, the Water Conservation Programme, the Water Recycling Programme, and campus water pollution control practices.
Domestic wastewater and clean rainwater are collected through separate networks in campus buildings. This prevents rainwater from mixing with contaminated wastewater and enables different water flows to be managed appropriately at source. Domestic wastewater is treated in Arsimak packaged biological wastewater treatment systems located on campus through primary sedimentation, equalisation, biological treatment, final sedimentation, and chlorination. Excess sludge generated during treatment is dewatered in sludge thickening and filter press units and disposed of in accordance with the relevant regulations.
Instead of being discharged directly, treated water is stored in retention ponds and reused for landscape irrigation, green space maintenance, toilet flushing systems in suitable buildings, cleaning, and other non-potable campus applications. Wastewater that cannot be reused is conveyed through the İSKİ sewerage network to the Tuzla Advanced Biological Wastewater Treatment Plant, where it undergoes advanced treatment. In addition, under the Protocol on the Transportation and Disposal of Wastewater dated 10 February 2021, wastewater can be transported by licensed vacuum tankers to authorised treatment facilities and disposed of through documented processes when required.
Laboratory wastewater containing chemical substances is not discharged into the domestic wastewater system. It is collected separately, stored in controlled temporary storage areas, and transferred to licensed hazardous waste management companies. Grease traps and filtration systems are used in cafeterias, kitchens, and maintenance areas to prevent oils, detergents, and suspended solids from entering the wastewater system. Waste cooking oil is collected separately and delivered to authorised recovery companies.
The University regularly inspects and maintains its ponds, drainage channels, rainwater collection systems, and wastewater infrastructure. To protect water quality, pH, conductivity, dissolved oxygen, and general water quality indicators are monitored. Through this integrated system, pollutants are prevented from reaching the soil and natural water bodies, water resources are protected, and environmental risks arising from campus operations are reduced.

SDG 15.4.2 Policy on Plastic Waste Reduction
Istanbul Okan University implements institutional practices to reduce plastic waste at source through its Zero Waste Management System and Programme to Reduce the Use of Paper and Plastic on Campus. The University’s approach is based on restricting single-use plastics, promoting reusable products, preventing unnecessary packaging, separating plastic waste at source, and transferring it to licensed recycling companies.
Water dispensers and refill stations across the campus encourage students and staff to use reusable water bottles, thermoses, and cups instead of single-use plastic bottles. Reusable plates, cups, and cutlery are prioritised in dining halls and cafeterias, while plastic bags and other single-use plastic products are restricted. The University also encourages the reduction of single-use plastics and the use of recyclable or biodegradable packaging during meetings, conferences, and campus events.
Plastic waste generated on campus is separated at source using colour-coded waste bins located in academic and administrative buildings and communal areas. The collected waste is transferred to licensed recycling companies in accordance with national environmental legislation. Plastic bottle cap collection campaigns and training programmes on zero waste and sustainable consumption encourage the campus community to participate in plastic reduction and waste separation activities.
Plastic reduction initiatives are supported by the Zero Waste Consultancy Service Agreement dated 28 February 2020, the Zero Waste Certificate dated 18 January 2021, the Waste Management Directive, separate waste collection infrastructure, and annual waste monitoring records. The University periodically compares the quantities of plastic waste generated and uses the results to improve its waste reduction programmes.

SDG 15.4.3 Policy on Hazardous Waste Disposal
Istanbul Okan University manages hazardous waste generated by laboratories, healthcare units, research facilities, and technical operations in accordance with its Zero Waste Management System, Waste Management Directive, and related implementation procedures. Hazardous waste management includes identifying waste at source, collecting it separately from other waste streams, applying appropriate labels, ensuring safe temporary storage, maintaining records, and transferring the waste to licensed companies.
The main types of hazardous waste generated at the University include residues of solvents, acids, bases, and reactive substances; contaminated laboratory tubes, pipettes, bottles, and other consumables; expired or unused chemicals; waste batteries and accumulators; hazardous components of electronic equipment; and medical and biomedical waste. These waste streams are collected in sealed, clearly labelled containers compatible with their properties and stored in controlled temporary storage areas.
Chemical liquids generated by laboratories are not discharged into the domestic wastewater system. Chemical waste is collected separately and transferred to licensed hazardous waste management companies. Waste batteries generated on campus are deposited in dedicated battery collection boxes. Medical and biomedical waste from healthcare units and laboratories is separated at source and collected, transported, and disposed of by authorised organisations.
The collected hazardous waste is transferred to licensed organisations authorised by the Ministry of Environment, Urbanisation and Climate Change. Medical and biomedical waste is directed to sterilisation or incineration, while chemical waste undergoes recovery, neutralisation, incineration, or safe disposal, depending on its properties. The type and quantity of waste, delivery date, transportation process, and final treatment method are recorded and monitored. The medical waste collection, transportation, and disposal process implemented in cooperation with Tuzla Municipality is one of the operational examples supporting this system.
To prevent hazardous waste from harming human health, animals, soil, and water resources, the University provides relevant personnel with training on waste segregation, laboratory safety, chemical management, and emergency response. Temporary storage areas and waste records are regularly inspected and monitored to ensure regulatory compliance and continual improvement.
