University-Wide Waste Monitoring

Universitas Islam Sultan Agung (UNISSULA) measures and monitors the amount of waste generated across the university as part of its environmental management and waste-reduction efforts.

The university maintains a dedicated Waste Monitoring Dashboard that records waste generation by period, tracks major waste categories, and identifies the amount of waste that is recycled or otherwise recovered from the waste stream.

The monitoring system provides university-wide data and allows waste performance to be reviewed on both a monthly and annual basis.

Waste Monitoring Dashboard

UNISSULA’s Waste Monitoring Dashboard provides a centralised overview of campus waste generation.

The dashboard includes information on:

• Total waste generated;
• Food waste;
• Garden waste;
• Other waste;
• Recycled waste;
• Monthly waste trends;
• Waste composition;
• Annual monitoring records; and
• Verification status of recorded data.

The dashboard enables university administrators to monitor changes in waste generation throughout the year and assess the effectiveness of waste-management activities.

Measurement of Total Waste Generated

The university records the total amount of waste generated each month.

For example, in December 2025, the dashboard recorded:

• Total waste generated: 7,320 kg
• Food waste: 5,900 kg
• Garden waste: 980 kg
• Other waste: 440 kg

The monthly data allow the university to compare waste generation between different periods and identify changes in waste patterns.

Waste Measurement by Category

Waste is recorded according to major categories to provide a clearer understanding of the composition of campus waste.

The principal categories monitored are:

Food Waste

Food waste represents the largest proportion of the university’s recorded waste stream.

This category includes organic waste arising primarily from food consumption and food-service activities within the university environment.

Garden Waste

Garden waste includes organic material generated through campus landscaping and green-space maintenance.

This may include leaves, grass clippings, plant material, and other biodegradable waste produced through the maintenance of university grounds.

Other Waste

The monitoring system also records waste that does not fall within the principal food or garden waste categories.

This enables the university to maintain a more complete record of the overall campus waste stream.

Measurement of Recycled Waste

In addition to measuring total waste generation, UNISSULA separately records the amount of waste that is successfully recycled or recovered.

The dashboard presents Recycling Waste as a monitored indicator alongside the main waste categories.

For December 2025, the university recorded:

• Garden Waste: 980 kg
• Recycled Waste: 101.9 kg
• Recycling proportion: 10.40% of garden waste

The recycled amount is recorded as a portion of the relevant waste stream and is therefore not added again to the total waste generated.

This approach prevents double counting and allows the university to distinguish between waste generated and the portion subsequently diverted through recycling or recovery activities.

Monthly Recycling Monitoring

Recycling performance is monitored throughout the year rather than being recorded only as an annual figure.

The 2025 dashboard records the following monthly recycled amounts:

The monthly figures demonstrate that recycling is measured continuously and can vary from one period to another.

Annual Waste Measurement

The monitoring system also provides annual totals.

For 2025, UNISSULA recorded:

• Total waste generated: 78,410 kg
• Food waste: 63,050 kg
• Garden waste: 10,800 kg
• Other waste: 4,560 kg
• Recycled waste: 1,082.7 kg

Because recycled waste represents a portion of the relevant waste category, it is tracked separately as a recovery indicator rather than being treated as an additional waste category in the total calculation.

Monthly Trend Analysis

The dashboard presents waste generation in a monthly trend graph.

This enables the university to observe:

• Increases or decreases in total waste;
• Changes in food waste generation;
• Changes in garden waste;
• Fluctuations in recycled waste; and
• Seasonal differences in waste production.

Trend monitoring provides a stronger basis for identifying periods of higher waste generation and determining where waste-reduction initiatives may be needed.

Waste Composition Monitoring

The dashboard also visualises the composition of campus waste.

For December 2025, the dashboard shows the relative proportions of food waste, remaining garden waste, recycled waste, and other waste.

This visual representation helps users understand which waste streams contribute most significantly to overall waste generation.

Avoiding Double Counting

UNISSULA distinguishes carefully between:

• Waste generated; and
• Waste recycled.

Recycled waste is a portion of waste already included within the total waste generated.

For example:

Garden Waste Generated → Portion Recycled → Remaining Garden Waste

This accounting approach ensures that recycling data can be monitored without inflating the total amount of waste generated.

Data Recording and Verification

The waste-monitoring system maintains monthly records for the entire reporting period.

The dashboard includes status indicators showing that recorded data have been entered and verified within the monitoring system.

This supports consistency in university waste records and makes it possible to review historical data when evaluating environmental performance.

University-Wide Coverage

The monitoring framework is designed to represent waste generated across university operations rather than waste from only a single faculty, department, or activity.

This university-wide approach allows UNISSULA to assess its overall waste profile and establish a consistent institutional record of waste generation and recycling.

Data-Based Waste Management

Waste measurement is an important part of UNISSULA’s environmental management approach.

Reliable data allow the university to:

• Identify major waste streams;
• Monitor changes in waste generation;
• Measure recycling performance;
• Evaluate waste-reduction activities;
• Identify opportunities for further recycling;
• Support more efficient use of resources; and
• Improve future waste-management programmes.

Supporting Waste Reduction

Measurement provides the baseline needed for effective waste reduction.

By understanding how much waste is generated and how much is recycled, the university can identify where interventions may have the greatest impact.

This supports a continuous cycle of:

Measurement → Evaluation → Reduction → Recycling → Improvement

Supporting Responsible Consumption and Production

The university’s waste-monitoring system supports SDG 12: Responsible Consumption and Production by providing measurable information on resource use, waste generation, and recycling.

Monitoring enables UNISSULA to move beyond general environmental commitments by maintaining quantitative records of its waste-management performance.
