Waste Measurement Report 2025
An-Najah National University (ANNU), as an institution, measures the amount of waste generated across the University and the amounts recycled and sent to landfill. Measurement is mandated by the University's approved Waste Measurement and Recycling Management Policy, applies to all University campuses, faculties and University-managed facilities, and is coordinated centrally by the Office of Sustainability in cooperation with the Facilities and Maintenance Department.
Waste quantities are recorded in kilograms in a central University Waste Register, consolidated monthly, and reported annually in metric tonnes. The results for calendar year 2025 are published in this report on the University website as part of ANNU's commitment to transparent sustainability reporting.
This report presents the 2025 results of ANNU's institutional waste measurement programme. It sets out what is measured, where, by whom, how, and how often, together with the annual quantities of waste generated, recycled and sent to landfill.

Reconciliation: 46 t generated = 45 t recycled + 1 t sent to landfill. Recycling rate = 45 ÷ 46 × 100 = 97.83%. Landfill share = 1 ÷ 46 × 100 = 2.17%. No other waste destination is unaccounted for within the reporting boundary described in Section 3.
Measurement covers waste generated by University operations across the whole institution, in line with Section 3 of the Waste Measurement and Recycling Management Policy. The 2025 reporting boundary includes:
-
All ANNU campuses and University-managed sites.
-
All faculties, departments, offices, libraries, laboratories, workshops, cafeterias, student facilities and University-managed residences.
-
University farms, agricultural and animal-husbandry facilities, and landscaped grounds.
-
Construction and demolition waste from University-managed projects, where generated in the period.
Waste generated by external organizations and externally sourced material processed in University facilities (for example, organic material received for composting research) is excluded from ANNU-generated totals and recorded separately.

How waste is measured
-
Segregation at source: colour-coded containers separate paper and cardboard, plastics, metals, glass, organic waste, general residual waste and hazardous waste.
-
Weighing: waste is weighed on calibrated scales at collection points, or weights are taken from weighbridge tickets and contractor or municipal documentation.
-
Recording: each collection is entered in the central Waste Register (Section 5.2).
-
Destination tracking: each quantity is linked to its documented management route — recycling, composting, reuse, other treatment, or landfill.
-
Consolidation: data are consolidated monthly by the Office of Sustainability and aggregated annually; kilograms are converted at 1,000 kg = 1 t.
-
Verification and approval: monthly totals are cross-checked against receipts and certificates; annual results are reviewed by the Sustainability Steering Committee before publication.

Definitions applied
-
Waste generated: all solid waste arising from University operations within the boundary in Section 3.
-
Waste recycled: material accepted by a recycling or composting process, evidenced by receipts or internal processing records. Material placed in a recycling bin is not counted as recycled unless collection or processing is documented; rejected loads are assigned to their actual final destination.
-
Waste sent to landfill: residual waste disposed of at a municipal or licensed landfill.
-
Reuse, energy recovery (including bioenergy research), chemical neutralisation, sterilisation and incineration are recorded separately and are not counted as recycling.
Estimation and data quality
Where direct weighing is not possible, a documented estimation method is used (for example, container volume multiplied by a measured density factor). The register identifies the method, assumptions and reason, and estimated quantities are flagged separately from measured ones.
The tables below present the measured 2025 quantities recorded in the University Waste Register for each waste stream, by destination. All quantities are in metric tonnes.

Organic waste recycling consists of composting and other material recycling. Direct agricultural reuse and bioenergy processing are not counted as recycling. Paper categories are mutually exclusive, so no material is counted in both the organic and inorganic tables.

Measured waste by group, 2025.
Measured waste by group and destination, 2025.
Composition of waste generated in 2025: organic 70.65%, inorganic 29.13%, electronic 0.22%. Electronic waste (0.100 t) was sent to specialised material recycling. Hazardous chemical, laboratory and clinical waste is managed under the Hazardous Waste Management Policy and recorded separately by licensed handling route; chemical neutralisation, sterilisation and incineration are not counted as recycling.

Total waste generated, 2024 and 2025.
Total waste generated fell by approximately 12 t (about 21%) between 2024 and 2025. In 2025 the University applied the stricter recycling definition in its Waste Measurement and Recycling Management Policy, under which bioenergy and direct reuse are no longer counted as recycling; year-on-year comparisons should be read with this in mind.
Recycling and composting
-
Colour-coded recycling stations for paper, plastics, glass and metals across campuses.
-
On-campus composting of food, landscaping and agricultural organic waste, with compost used in University farms and grounds.
-
Agreements with local recycling companies for paper, plastics and metals.
-
Collection of electronic waste and batteries for transfer to specialised recyclers.
-
Student-led collection drives for paper and plastics.
Reuse (recorded separately from recycling)
-
Refurbishment and redistribution of furniture and equipment between departments, and donation to schools.
-
Reuse of wood and metal in student workshops; reuse of clean glassware in laboratories.
-
Use of manure and suitable residues as organic fertiliser on University farms.
Waste prevention
-
Electronic workflows and default double-sided printing.
-
Water refill stations and reusable bottles under the Plastic Use Reduction and Sustainable Materials Policy.
-
Microscale laboratory practice and controlle
The annual results inform University operational decisions, waste-reduction targets and sustainability reporting. Priorities for 2026 are:
-
Increase the share of directly weighed tonnage relative to estimates.
-
Report hazardous, electronic and clinical waste quantities alongside general waste in a single integrated inventory.
-
Publish monthly data summaries on the Sustainability webpage.
This report is publicly available on the An-Najah National University website. Supporting records — weighing logs, weighbridge tickets, contractor receipts, recycling certificates and the monthly Waste Register — are held by the Office of Sustainability and are available for verification on request.
