Atık bebek bezlerinin sürdürülebilir ve döngüsel yönetimi

Öz

Kullanılmış bebek bezlerinin yönetimi, doğal kaynaklar üzerindeki küresel tüketimin hızlı şekilde artması ve bu tüketimin sebep olduğu çevresel etkiler nedeniyle giderek artan kritik bir konudur. Dünya çapında sürekli üretimle birlikte 2023 yılı itibariyle 222 milyar adet (yaklaşık 90 milyon ton) bebek bezinin atık olarak oluşması beklenmekte ve bu miktar her yıl giderek daha da artmaktadır. Kimyasal kompozisyonlarına bağlı olarak, bu materyaller sentetik polimerler (SAP) içeriklerinden dolayı biyolojik olarak parçalanamayan atıklar olarak nitelendirilse de özellikle SAP, plastikler ve selülozik bileşenler depolama sahalarına veya yakma tesislerinde bertaraf edilmek yerine geri kazanılabilir özelliklerdedir. Ancak henüz gelişmekte olan ülkelerde alternatif geri dönüşüm ya da kullanım seçenekleri mevcut olmadığından, uygun maliyetli ve verimli teknolojiler hızlı gelişme gösteren araştırma alanı olarak ortaya çıkmıştır. Bu bağlamda, çalışmanın amacı da, sürdürülebilirlik ve döngüsel ekonomi çerçevesinde SAP, selülozun ve plastiğin değerlendirilmesine ve atık yönetimi ile ilgili sera gazlarının (GHG) ve maliyetlerin azaltılmasına olanak sağlayacak yenilikçi geri dönüşüm teknolojilerinin geliştirilmesi ve uygulanması hakkında bilgi birikimi oluşturmaktır. İleri teknolojilerin hayata geçirilmesi ile hem geri dönüşüm en üst düzeye çıkarılacak hem de kaynak israfı ile atık miktarı da en aza indirilecektir.

Anahtar Kelimeler

• Atık bebek bezleri
• sürdürülebilirlik
• kaynak verimliliği
• geri dönüşüm.

Sustainable and circular management of used baby diapers

Öz

The management of soiled baby diapers is a critical subject aggravated by the exponential increase of global consumption on natural resources and their consequent impact on environment. Due to continuous worldwide production, it is expected that 222 billion diapers (almost 90 million tons) will be generated as a waste by 2023 and this amount is increasing every year. As regards chemical compositions, these materials perceive as a non-biodegradable waste because it is made of synthetic polymers (SAPs); nevertheless, specifically the SAP, plastics and cellulosic components could be recycled instead of going to landfill or incineration plants. However, no alternative recycling or valorization options is available yet, so the cost effective and efficient state of the art technologies have emerged as a research area that is undergoing rapid development. In this context, the objective of this study are to provide insights into develop and implement new recycling technologies for sustainability and circular economy which would allow valorization of the SAPs, cellulose, and plastic and decrease of waste management related greenhouse gas (GHG) and costs. With the implementation of innovative technologies, recycling will be maximized and the waste of resources and the amount of waste will be minimized.
