Salgın öncesi cam bardak, tabldot, tabak, kaşık, çatal gibi yıkanabilir ve tekrar kullanılabilir malzemeler kullanılırken, salgın sonrası tek kullanımlık mutfak gereçleri kullanılmaktadır. Tek kullanımlık mutfak gereçlerinde kullanılan materyallerin her geçen gün kullanımı artmakta ve çevresel sorunlara neden olmaktadır.  Bu çalışmada, tek kullanımlık Expanded Polystyren Foam (EPS) ve Polietilen Tereftalat (PET) malzemelerinden imal edilen bardakların yaşam döngüsü değerlendirmesi yapılarak, çevreye ve insan sağılığına zararı en az olan ürünün belirlenmesi amaçlanmıştır.  Yaşam döngüsü değerlendirmesi, openLCA yazılımı kullanılarak, uluslararası standartlar olan ISO 14040 ve ISO 14044 standartları uygulanmıştır. Çalışma sonunda, EPS bardak ve PET bardak tüm kategorilerde çevreye ve insan sağlığına zararlı olduğu tespit edilmiştir. PET bardak, EPS bardağa göre daha fazla insan sağlığı ve çevreye zararlı olduğu belirlenmiştir.  EPS ve PET bardak üretimlerdeki küresel ısınma potansiyeli, %9,21 farkla PET bardakta daha yüksek tespit edilmiştir.  Yapılan yaşam döngüsü değerlendirmesi sonucunda üretim aşamasından kaynaklanan emisyonların azaltılması için ham madde ve enerji girdileriyle ilgili iyileştirme çalışmalarının gerekliliği ortaya çıkmıştır</p></abstract>

                            <p>After the Covid-19 outbreak, especially restaurants, shopping malls and eateries started to use single sale products more. Before the epidemic, washable and reusable materials such as glass cups, table d&#039;hote, plates, spoons and forks were used, while the only storage kitchen utensils used in the growing age were used. The use of disposable kitchen utensils is increasing day by day and the seasons change. This successful, single-improvement evaluation of the life history of cups made of Expanded Polystyrene Foam (EPS) and Polyethylene Terephthalate (PET) materials, maintenance and discontinuation of the product with the least harm to human health. Evaluation of life outcomes, openLCA software system, international standards ISO 14040 and ISO 14044 have been prepared. At the end of the study, it was determined that EPS cups and PET cups are harmful to human health in all their elements. PET cups have been found to be more harmful to human health and harmful health conditions than EPS cups. The global energy potential in EPS and PET cup production was determined to be higher in PET cups with a difference of 9.21%. The result of the life report evaluation revealed the appropriate adequacy of raw materials and energy inputs to reduce emissions resulting from the production phase.</p></trans-abstract>
