In the 21st century, humanity has reached the highest level of plastic consumption in history. These plastic products are not biodegradable and therefore do not decompose in nature, causing global plastic pollution. Recently, plastic pollution has garnered significant attention, leading the scientific community to focus on plastic pollution and waste management. Studies have shown that effective waste management can be implemented in daily life with appropriate actions. One of the major consumers of plastic is the office environment, where efficient plastic waste management can be realized. This study successfully demonstrates the recycling of plastic waste into granules and fiber for use in mass production systems. The necessary investments for plastic recycling were determined, and the optimal investment was selected using the Net Present Value (NPV) and maximum regret value methods. Subsequently, the processes for obtaining granules and fibers were carried out. This study highlights the environmental and economic benefits of recycling plastic.

21. yüzyıl itibariyle, insanlık tarihinin en yüksek plastik tüketim seviyesine ulaşılmıştır. Kullandığımız plastik ürünler biyolojik olarak parçalanabilir ürünler değildir, dolayısıyla doğada çözünemezler. Bu nedenle plastik atıklar küresel plastik kirliliğine neden olmaktadır. Son yıllarda plastik kirliliği büyük ölçüde gündeme gelmiştir. Bu nedenle bilim çevreleri plastik kirliliği ve atık yönetimi konularına daha fazla ilgi göstermektedir. Son yıllarda yapılan çalışmalar ve araştırmalar, atık yönetiminin günlük hayatta etkili bir şekilde gerçekleştirilebileceğini ortaya koymaktadır. Plastik tüketiminin en fazla gerçekleştiği yerlerden biri olan ofis ortamlarında etkin bir plastik atık yönetimi uygulanabilir. Bu çalışmada, plastik atıkların seri üretim sistemlerinde işlenmek üzere granül ve elyaf olarak geri dönüşümü başarıyla gerçekleştirilmiştir. Plastik geri dönüşümü için öncelikle yatırım gereklilikleri belirlenmiştir. Sonuç olarak, NPV (Net Bugünkü Değer) ve Maksimum Pişmanlık Değeri yöntemlerinin entegre kullanımıyla gerçekleştirilen bir karar verme metoduyla en uygun yatırım seçilmiş ve gerçekleştirilmiştir. Ardından, granül ve lif elde etme işlemi uygulanmıştır. Bu çalışma, plastik geri dönüşümünün çevreye ve ekonomiye nasıl yardımcı olduğunu göstermektedir.
