Sustainable Development Goals

Chapter I: Waste Management Principles

1.1 Background

Universities have an essential role as agents of change, not only through education and research but also through campus operations in support of the Sustainable Development Goals (SDGs). One unavoidable challenge is waste management. Every activity within the campus environment, whether academic or non-academic, has the potential to generate waste, which must be managed responsibly. Therefore, effective and efficient waste management is crucial in supporting sustainable development.

ITS is committed to prioritizing efficient waste management as part of its responsibility toward generated waste. With a campus area of 144.5 hectares, ITS faces a significant waste management challenge, with daily waste generation reaching 2,800 kg. Of this, approximately 2,300 kg comes from daily activities, with the largest composition being paper waste (30%), followed by plastic waste (23%) and food waste (22%). Additionally, tree pruning and street cleaning activities produce around 785.2 kg of leaf and branch waste per day, constituting 28.04% of the total daily waste.

Currently, waste at ITS is managed sustainably through innovative approaches that integrate various waste management programs, including source sorting, waste banks, and composting. These efforts not only reduce the amount of waste sent to final disposal sites but also contribute to an environmentally friendly waste management system based on the 3R principles (Reduce, Reuse, Recycle). Active participation from all members of the academic community is essential for successful waste management on campus. With the involvement of students, faculty, and staff, waste management can be carried out more effectively and efficiently. Therefore, a waste management governance system was developed at ITS as a clear procedure for all academic members to participate actively and support the campus’s environmental impact reduction efforts.

1.2 Objectives

The objectives of developing waste management governance at ITS are as follows:

• Support environmental sustainability with governance aligned with sustainable principles.
• Increase awareness and participation among the academic community through clear waste management governance.
• Support sustainable development through the implementation of waste management governance procedures.

1.3 Waste Management Concept

Waste refers to remnants from human daily activities and/or natural processes in solid form. Waste generation refers to the amount of waste produced by sources, expressed in volume (liters/person/day) or weight (kg/person/day). Waste can be categorized by source into three types:

• Household Waste: Derived from daily household activities, excluding sewage and specific waste.
• Household-like Waste: Derived from commercial areas, industrial areas, special areas, social facilities, public facilities, and/or other facilities.
• Specific Waste: Waste that requires special management due to its nature, concentration, and/or volume, including:
  • Hazardous and Toxic Waste (B3)
  • Waste generated from disasters
  • Construction debris
  • Waste that cannot be processed with current technology
  • Irregularly occurring waste

Waste management is a systematic, comprehensive, and sustainable activity that includes waste reduction and handling. Waste reduction activities include:

• Waste minimization
• Waste recycling
• Waste reuse

Waste handling activities involve five stages as per Indonesian Law No. 18 of 2008 on Waste Management:

1. Sorting: Grouping and separating waste by type, amount, and/or properties, into at least five types: hazardous waste, biodegradable waste, reusable waste, recyclable waste, and other waste requiring disposal.
2. Containment: Using separate containers for each waste type to facilitate sorting.
3. Collection: Taking and moving waste from sources to temporary storage or integrated waste processing facilities.
4. Transportation: Transporting waste from sources or temporary storage to final processing sites without mixing sorted waste.
5. Processing: Altering waste characteristics, composition, and quantity.
6. Final Disposal: Safely returning waste or residual processed waste to the environment.

Chapter II: Standard Operating Procedures for Waste Management at ITS

All waste generated at ITS must be handled appropriately from the source to its final processing. This starts with comprehensive sorting and containment at each department, office, canteen, and campus area. Waste is then processed within the campus before being transported to Temporary Storage Sites (TPS) and Final Disposal Sites (TPA). Waste management is a shared responsibility, and all members of the academic community are expected to adhere to the standard operating procedures provided.

2.1 Waste Sorting Procedures on the ITS Campus

Waste is sorted into five categories to facilitate further processing:

• Organic Waste: Food scraps, dry leaves
• Paper Waste: Newspapers, magazines, used books, cardboard
• Plastic Waste: Plastic bottles, plastic bags
• Residual Waste: Cigarette butts, tissue, rubber
• Specific Waste: Hazardous waste (B3), electronic components

2.2 Waste Containment Procedures on the ITS Campus

Each waste category is designated with a specific color container to simplify sorting. Each container is made from fiberglass or aluminum with capacities ranging from 60 to 240 liters:

• Green: Organic waste
• Blue: Paper waste
• Yellow: Plastic waste
• Gray: Residual waste
• Red: Specific waste (B3 and electronics)

2.3 Waste Collection and Transportation Procedures on the ITS Campus

Waste collection involves transferring waste from various campus units to designated collection points using labeled plastic containers or bins. Organic waste suitable for composting is collected daily, and other waste types, including recyclable and specific waste, are collected based on a set schedule. Specific waste, including hazardous and electronic waste, is stored in temporary facilities until further processing or disposal.

2.4 Waste Processing Procedures on the ITS Campus

ITS operates composting facilities on campus to process organic waste, with an average reduction of 25% of total daily waste through composting. Waste suitable for sale is handled by the ITS TaSTe Waste Bank, where it is separated, weighed, and recorded, then sold to partnering companies.

a. Composting
ITS provides composting facilities located on Jalan Arief Rahman Hakim, with compost bins distributed across various campus areas. These facilities process leaf and branch waste from street sweeping, achieving a waste volume reduction of approximately 685.2 kg/day, or about 25% of total waste. The composting procedure at ITS includes:

1. Leaf Collection
   Leaves gathered from street sweeping are transported to the ITS compost facility, where they serve as the base material for composting.
2. Waste Fermentation
   Collected leaves undergo fermentation in conventional composting bins for 7 to 30 days to accelerate decomposition.
3. Waste Shredding
   After fermentation, the waste is shredded to reduce particle size.
4. Screening
   The shredded compost is screened to separate fine particles from coarser materials, which are reprocessed. Fine particles become ready-to-use compost.
5. Ready-to-Use Compost
   Finished compost is packaged and used as organic fertilizer for plant cultivation.

b. Waste Bank (TaSTe ITS)
ITS has established a waste bank named Tabungan Sampah Terpadu (TaSTe ITS), which allows the ITS community to sell recyclable waste. The waste bank operates through its website, taste.its.ac.id. Users can convert recyclables into cash points, which can be withdrawn via the website.

A sample list of recyclable items and prices at TaSTe ITS:

Customer Procedures at TaSTe ITS:

• Registration: Customers register on the TaSTe ITS website (tutorial link), available for ITS students, staff, vendors, and the general public.
• Drop-Off: Customers bring recyclables to the TaSTe ITS office and confirm with an admin.
• Weighing and Recording: Staff sort and weigh items, and points are added to the customer’s account.
• Waste Sales: Collected recyclables are sold to the main waste bank twice monthly.
• Withdrawal: Customers may withdraw funds monthly with a minimum balance of 20,000 points (1 point = Rp 1) by contacting admins through WhatsApp.
• Transaction Services: Available Monday-Friday, 1:00 PM – 3:00 PM.

c. Specific Waste (E-Waste)
Specific waste management at ITS targets electronic waste (e-waste), such as computers, AC units, and printers. Procedures include:

• Identification and Inspection: E-waste stored at the B3 Waste TPS is inspected by technicians to assess repair potential.
• Reuse and Recycling: Repairable items are either reused or recycled, restoring value and reducing waste.
