Fiber-reinforced composites, such as carbon and glass fibers, are widely used across various industries. This is mainly a result of their outperforming properties in contrast with traditional materials. As a response to the environmental legal enforcement of the recycling of composite materials, several recycling methods such as mechanical, thermal, and chemical recycling, have been developed. Despite various merits, these recycling methods still face challenges, such as the heterogeneity of material, the quality of the recycled product, the high cost of recycling, and a lack of an established market. Since, in many cases, the financial aspect tends to be the major barrier to recycling composites, the appropriate cost modelling of the recycling process requires urgent consideration. To the knowledge of the authors, there is no prior research efforts on the reviewing of cost modelling techniques on composites recycling. Cost modelling research projects for different recycling technologies, with their findings and limitations, are sought from the literature and reported in this paper. It is found that recycling techniques still cannot compete with traditional landfilling in terms of cost, and are dependent on fiber recovery rates and plant capacities. Following a comprehensive literature review, research gaps are identified to formulate the research directions in this field.

“…The countries within the European Union, comprising a population of around 400 million people, produce a significant amount of waste. Between the years 1995 and 2019 [1], there was a notable rise in the annual growth of municipal solid waste (MSW) generation per individual in the European Union (EU) from 198 million metric tonnes (equivalent to 467 kg per capita) to 224 million metric tonnes (equivalent to 502 kg per capita), representing an increase of over 30% [2]. The escalation in demand for goods across all sectors has resulted in an increase in waste generation.…”

Various waste streams including municipal solid waste (MSW), polymer waste from personal protective equipment (PPE) used in medical fields, and composite waste from wind turbine blades (WTBs) demand modern waste management and recycling approaches. Ultimate and proximate analysis of mentioned samples revealed a higher content of carbon—28.2 ± 8.0, 80.1 ± 2.3, and 50.3 ± 2.3, respectively—exhibiting sufficient potential to be converted into secondary carbon-based compounds. For this purpose, oxidative liquefaction of selected waste materials was carried out following a detailed experimental plan, a centred composite design for WTBs, and a central composite face-centred plan for MSW and PPEs. Temperature, pressure, oxidant concentration, reaction time, and waste-to-liquid ratio were the parameters of key interest, and their values were tested at a range of 200–350 °C, 20–40 bar, 15–60%, 30–90 min, and 3–25%, respectively, depending upon the type of waste. As a result, total polymer degradation (TPD) was recorded for three types of waste and the results were satisfactory, encouraging the decomposition of primary waste in liquid oxygenated chemical compounds (OCCs). Gas Chromatography with Flame Ionisation Detection (GC-FID) helped us quantify the number of OCCs for each waste sample. Energy consumption during the process was also recorded and optimisation of the experimental plan based on maximum TPD and OCCs yields against the minimum energy consumption was performed to make the process tech-economic.

Kebutuhan mendesak akan praktik pengelolaan sampah yang berkelanjutan telah menyebabkan meningkatnya minat terhadap inovasi daur ulang yang menawarkan manfaat lingkungan dan kelayakan ekonomi. Studi literatur ini bertujuan untuk mengeksplorasi kemajuan dalam metodologi daur ulang dan implikasinya untuk mendorong ekonomi yang berkelanjutan dan sirkular. Melalui tinjauan sistematis terhadap literatur yang relevan, termasuk artikel yang diulas oleh rekan sejawat, prosiding konferensi, buku, dan laporan, studi ini mengkaji pendekatan daur ulang, manfaat lingkungan, dan kelayakan ekonomi. Hasil tinjauan literatur mengungkapkan beragam pendekatan daur ulang, termasuk metode mekanis, kimiawi, dan biologis. Daur ulang mekanis, metode yang paling umum digunakan, melibatkan pemilahan dan pengolahan bahan limbah untuk membuat bahan baku sekunder untuk pembuatan produk baru. Teknologi canggih telah meningkatkan efisiensi dan efektivitas daur ulang mekanis. Teknik daur ulang kimiawi, seperti pirolisis dan gasifikasi, mengatasi tantangan yang terkait dengan aliran limbah yang kompleks. Metode daur ulang biologis, termasuk pengomposan dan pencernaan anaerobik, secara efektif mendegradasi bahan limbah organik. Manfaat lingkungan dari inovasi daur ulang sangat signifikan. Daur ulang menghemat energi, mengurangi emisi gas rumah kaca, dan membantu melestarikan sumber daya alam dengan mengurangi kebutuhan ekstraksi. Hal ini juga mengurangi risiko lingkungan yang terkait dengan penimbunan sampah dan berkontribusi pada ekonomi sirkular dengan mengalihkan sampah dari TPA. Secara ekonomi, inovasi daur ulang menunjukkan kelayakan. Daur ulang dapat menghemat biaya dibandingkan dengan metode pembuangan sampah tradisional, terutama jika mempertimbangkan biaya TPA, harga bahan baku, dan peraturan lingkungan. Sektor daur ulang menghasilkan peluang kerja dan berkontribusi pada pertumbuhan ekonomi, mendorong ekonomi hijau dan menciptakan jalan bisnis baru. Namun, kelangsungan ekonomi daur ulang bergantung pada permintaan pasar untuk bahan dan produk daur ulang.
