Abstract
Solid waste is a growing concern, driven by population growth, urbanization, and the industrial
revolution. Inadequate management leads to higher costs, environmental damage, and health
risks. Integrating effective waste management systems is crucial for sustainable development.
This research explores solid waste management in higher educational institutions. It aims to
implement waste reduction strategies, assess student awareness, analyze economic aspects, and
ensure financial viability. The findings contribute to the development of sustainable waste
management practices in this context, serving as a reference for other institutions.
This research focuses on the cafeteria of An-Najah National University, where solid waste was
sorted into five main categories: glass, cardboard, plastic, metal, and organic material. Over a
15-day period, the weights of each waste type were measured, along with the mixed waste
generated from the cafeteria. The average daily quantities were determined as 11.0 kg for
separated waste and 152.0 kg for mixed waste, resulting in a separation rate of 6.7%.
To increase student awareness, a campaign was conducted, accompanied by a questionnaire to
assess students' knowledge of solid waste management and related issues. Interviews were also
conducted with key stakeholders, local traders, and the university's services department to
gather data on unit prices for each waste type, university expenses, and project capital.
The collected data underwent analysis using Excel, economic models, and mathematical
equations. This analysis determined the total quantities and calculated the potential revenue
from selling each waste type, taking into account the capital cost, expenses, and savings. The
equal payment series method was then applied, resulting in a projected present worth value of
396,400 NIS in five years, assuming the interest rate is 5%, indicating the project's high
feasibility.
Based on the project results, recommendations are proposed for the university to consider,
aiming to expand the initiative and revise relevant policies. This research contributes valuable
insights to the development of a sustainable waste management strategy at An-Najah National
University, and it serves as a potential model for other institutions seeking effective solutions
to waste management challenges
