Contribution to sustainability and the national economy through recycling waste paper from Istanbul’s hotels in Turkey

Abstract

Obtaining cellulose from recyclable waste paper contributes to the sustainability of forest resources, water and energy savings, and the reduction of environmental pollution. However, waste paper collected under inappropriate conditions for recycling can be degraded in a short time, thus becoming economically useless. This study examined the factors affecting source-separated collection processes of waste paper in Istanbul hotels, as well as the correlation among these factors. The economic value of the assumed benefits of source-separated waste paper was also calculated. To achieve these objectives, various inputs and methods were used, including the percent tabulation technique and the chi-square independence test. As a result, it was determined that 70% of managers and employees of Istanbul hotels were sensitive to recycling waste paper, but they were not aware of the entire benefits of waste paper recycling. It was also determined that because of waste paper recycling, 18 thousand trees, 5 million kWh of electricity, 3 thousand tons of water, and 1.3 thousand tons of fuel oil were saved, and the generation of 27 thousand tons of CO2 was prevented annually. Hotels in Istanbul provide the economy with an annual average of 752 tons of waste paper, which corresponds to 78% of the foreign trade deficit of Turkey’s paper and paper products sector in the last five years.

Decomposition dynamics of cooking-oil-soaked waste paper in media with low inorganic nitrogen content

“…Approximately 50% of this amount consists of package and labeling paper, whereas 28% is office printing paper. The increase in paper production will probably continue over the next years (Bekiroğlu et al 2017). Used office paper without impurities can easily be transformed into new paper of good quality, but wet paper, baking paper or packaging cardboard contaminated with cooking oil or other compounds cannot be recycled in this way.…”
