Background and Objectives: Integrated solid waste management is one of the biggest environmental challenges facing the public and private institutions. This requires knowledge of the composition and sources of waste production. The aim of this study was to determine the quality and quantity of common waste at the faculty of health and nutrition and medical schools. Material and Methods: This study was a cross sectional and descriptive study on the point of all-waste generated in both schools. A total of 24 samples were taken and weighted from each school. Data were analyzed with SPSS and Excel. T-test was used for comparison of means following normality test of the data. Results: Average of waste produced at faculties of health and nutrition and medicine were 37±7 and 30±3 kg per day, respectively. Paper and metals were the highest and lowest part of solid waste, respectively with daily average of 15 and 2 kg. Paper is accounted about 40 to 45 percent by weight of the total waste. Per capita waste production in the faculty of health and nutrition is nearly twice faculty of medicine. The total waste per capita of university was estimated at about 15 kg per person per year. Conclusion: University solid waste per capita, especially the amount of paper, is high compared with the other researches. The highest amount of waste material examined in this study is recyclable at source. Training programs and changes in attitude and practice must be applied for students and staff to produce less waste to protect environment and natural resource and create a green university.

This study presents 5-hydroxymethylfurfural removal from waste hand paper hydrolysate using activated carbon adsorption. In this context, the effects of adsorbent dosage, initial 5-hydroxymethylfurfural concentration, temperature, and agitation speed on 5-hydroxymethylfurfural adsorption were investigated. Moreover, isotherm and kinetic evaluations were performed using Langmuir, Freundlich, and Temkin models. The experimental data were correlated with zero, first, pseudo-first, and Weber–Morris intraparticle diffusion models. The toxicity of 5-hydroxymethylfurfural was determined using the resazurin reduction assay, and the EC50 of 5-hydroxymethylfurfural in the hydrolysate was found as 192 mg/L. Most convenient 5-hydroxymethylfurfural adsorption was obtained at 5 g/L AC dosage, 40 °C and 150 rpm agitation speed. The highest 5-hydroxymethylfurfural removal efficiency was 92% at 7 g/L AC dosage. The adsorption data fitted best with the Langmuir isotherm model with a maximum uptake capacity of 70.92 mg/g (R2: 0.96). The zero-order reaction kinetic model was the most suitable one among the others inspected. It was determined that intraparticle diffusion was not the rate-limiting step. This study showed that waste hand paper hydrolysate can effectively be detoxified by activated carbon adsorption. [ABSTRACT FROM AUTHOR]
