Plastik Atık Pirolizi Araştırmaları: Bilimsel Eğilimler ve Çevresel Etkiler Üzerine Kapsamlı Bir Bibliyometrik Analiz

Öz

Plastik atıkların pirolizi, atıkların yararlı yakıt ve kimyasallara dönüştürülmesi yoluyla plastik kirliliğini yönetmek için umut verici bir yöntemdir. Bu çalışma, 2000-2025 yılları arasında Web of Science veri tabanındaki 2.019 makale üzerinden plastik atık pirolizi üzerine yapılan araştırmaları analiz etmektedir. Bibliyometrik araçlar kullanılarak yayın eğilimleri, öne çıkan yazarlar ve kurumlar, popüler dergiler, ana araştırma konuları ve uluslararası iş birlikleri incelenmiştir. Bulgular, 2017 yılından itibaren çevresel farkındalığın artması ve yeni politikaların etkisiyle araştırmalarda hızlı bir artış olduğunu göstermektedir. En fazla katkı sağlayan ülkeler Çin, Hindistan, ABD ve İspanya, Polonya ve İtalya gibi Avrupa ülkeleridir. Öne çıkan kurumlar arasında Ghent Üniversitesi ve Malezya Teknoloji Üniversitesi yer almaktadır. Temel araştırma alanları arasında katalitik ve eş-piroliz teknikleri, reaktör tasarımı, ürün analizi ve çevresel etkiler bulunmaktadır. Yeni araştırma eğilimleri arasında mikrodalga destekli piroliz, hidrojen üretimi ve döngüsel ekonomi yaklaşımları öne çıkmaktadır. Tüm ilerlemelere rağmen, süreç verimliliğinin artırılması, çevresel etkilerin değerlendirilmesi ve yeterince araştırılmamış plastik türlerine odaklanılması gibi zorluklar sürmektedir. Bu çalışma, mühendislik ve çevre bilimlerini birleştiren iş birliğine dayalı ve disiplinler arası yapısıyla bu alandaki gelişmeleri özetlemekte; araştırmacılar ve karar vericiler için önemli konu başlıkları ve araştırma boşluklarını ortaya koymaktadır. Küresel plastik atık sorununa çözüm sağlamak ve sürdürülebilir kaynak kullanımı hedefini desteklemek için etkili ve büyük ölçekli piroliz teknolojilerinin geliştirilmesi adına sürekli araştırma ve iş birliği gerekmektedir.

Plastic Waste Pyrolysis Research: A Comprehensive Bibliometric Analysis of Scientific Trends and Environmental Implications

Öz

Plastic waste pyrolysis is a promising method to manage plastic pollution by turning waste into useful fuels and chemicals. This study analyzes research on plastic waste pyrolysis from 2000 to 2025 using 2,019 articles from the Web of Science database. Using bibliometric tools, it examines trends in publications, key authors and institutions, popular journals, main research topics, and international cooperation. Findings show a rapid increase in research since 2017, driven by growing environmental awareness and new policies. The top contributing countries are China, India, the United States, and European countries such as Spain, Poland, and Italy. Leading institutions include Ghent University and Universiti Teknologi Malaysia. Main research areas cover catalytic and co-pyrolysis techniques, reactor design, product analysis, and environmental effects. New trends focus on microwave-assisted pyrolysis, hydrogen production, and circular economy approaches. Despite progress, challenges remain such as improving process efficiency, assessing environmental impacts, and addressing under-researched plastics. The study highlights the collaborative and interdisciplinary nature of the field, combining engineering and environmental science. This overview helps researchers and decision-makers understand key topics and gaps. Continued research and cooperation are needed to develop effective, large-scale pyrolysis technologies that can help solve the global plastic waste problem and support sustainable resource use.
