Plastics are indispensable in daily life, with both production and waste generation increasing annually. As the world strives for net‐zero emissions, advancing plastic recycling technologies has become a global priority. Pyrolytic liquefaction is a promising approach for recovering chemical feedstocks, including fuel fractions, from waste plastics, potentially substituting petroleum resources. Since the 1970s, research on pyrolytic liquefaction has progressed globally, and several industrial‐scale plants are now in operation. However, to accelerate the transition to a circular economy, it is crucial to bridge the knowledge gap between lab‐scale research and industrial‐scale implementation of pyrolysis‐liquefaction technologies. This review provides a comprehensive analysis of the current state of plastic recycling, the progress and challenges in cutting‐edge lab‐scale research on pyrolytic liquefaction, alongside the latest trends in industrial‐scale liquefaction projects. It reveals that pyrolytic liquefaction of a wide range of plastics—including halogenated plastics and poly(ethylene terephthalate)—has been extensively studied at the laboratory level. In contrast, industrial‐scale operations often focus on more common, easily pyrolyzed plastics and generally avoid the use of catalysts. This highlights the urgent need to develop robust, reusable, and cost‐effective catalysts, as well as optimized process designs, to expand the range of plastic feedstocks suitable for industrial‐scale pyrolysis plants.

Abstract The introduction of biodegradable plastics is considered a practical approach to reducing plastic waste accumulation in the environment. Regardless of their biodegradability, plastics should be recycled to effectively utilize and circulate carbon as a resource. Herein, the use of pyrolysis was examined as a method for recycling two common biobased/biodegradable plastics: PLA and PHBH. The pyrolysis of PLA produced lactides (10.7 wt% at 400 °C), but the yield was decreased when the pyrolysis temperature was increased. The presence of steam promoted the hydrolysis of PLA: a steam concentration of 25 vol % increased, the production of lactides at 400 °C to 17.4 wt%. The pyrolysis of PHBH primarily yielded crotonic acid (30.1 wt% at 400 °C), and the yield increased with increasing pyrolysis temperature (71.8 wt% at 800 °C). Steam injection increased the hydrolysis of oligomers, resulting in a 76.1 wt% yield of crotonic acid at 600 °C with a steam concentration of 25 vol %. Thus, we determined that hydrolysis and pyrolysis progress simultaneously under a steam atmosphere, increasing the chemical feedstock recovery from PLA and PHBH. These findings may lead to the proposal of effective degradation methods for treating biobased/biodegradable plastic wastes and ways to maximize the conversion efficiency and target product yields.

Abstract Material recycling technologies are essential for achieving a circular economy while reducing greenhouse gas emissions. However, most of them remain in laboratory development. Machine learning (ML) can promote industrial application while maximising yield and environmental performance. Herein, an asynchronous-parallel recurrent neural network was developed to predict the dynamic behaviour when separating copper and poly(vinyl chloride) components from the cable waste. The model was trained with six datasets (treatment conditions) at 3600 epochs. High accuracy was confirmed based on a mean-square error of 0.0015–0.0145 between the prediction and experimental results. The quantitative relationship between the input features and the separation yield was identified using sensitivity analysis. The charged weight of cables and impact energy were determined as the critical factors affecting the separation efficiency. The ML framework can be widely applied to recycling technologies to reveal the process mechanism and establish a quantitative relationship between process variables and treatment outputs.

Abstract In this study, poly-lactic acid (PLA) and poly-3-hydroxybutyrate-co-3-hydroxyhexanoate (PHBH) were pyrolyzed at various temperatures (300, 350, 400, 500, 600, and 700 °C) and heating rates (5, 10, 20, 30, and 40 °C min⁻¹) using a pyrolysis–gas chromatograph/mass spectrometer (Py–GC/MS). The results revealed that the main pyrolysis products of PLA were acetaldehyde, lactide (including meso-lactide and d-, l-lactide), and oligomers. Crotonic acid and its oligomers accounted for most of the PHBH pyrolyzates. The pyrolysis temperature significantly correlated with the product distribution, but the heating rate had a small effect on the product distribution. Lactide and crotonic acid were two kinds of high-value chemicals, and their highest yields were obtained at 400 and 600 °C with 29.7 and 72.6 area %, respectively. Secondary reactions could not be neglected at 700 °C, and acetaldehyde and crotonic acid decreased to 65.0 and 69.6 area %, respectively. These results imply that pyrolyzate selectivity can be controlled by temperature management during pyrolysis.

Polycarbonate (PC) is an engineering thermoplastic that is widely used in electrical and electronic equipment. This plastic often contains tetrabromobisphenol A (TBBA), the most common brominated flame retardant. Thermal degradation of the PC-TBBA leads to generation of numerous bromo-organic products in the pyrolytic oil, hindering its appropriate utilization, as well as corrosive hydrogen bromide gas. The purpose of this study was to experimentally investigate and compare the pyrolysis products of PC-TBBA and PC-TBBA + Cu2O at various temperatures, with an emphasis on the yield and distribution of brominated compounds. In pyrolysis of PC-TBBA + Cu2O, at the maximum degradation temperature (600 °C), as much as 86% of total Br was trapped in the residue, while 3% and 11% were distributed in the condensate and gas fractions, respectively. In contrast, the distribution of Br from non-catalytic pyrolysis of PC-TBBA (600 °C) was 0.5% residue, 40% condensate, and 60% gas. The results of this study revealed that in the presence of Cu2O, organo-bromine products were most likely involved in Ullman-type coupling reactions, leading to early cross-linking of the polymer network that efficiently hinders their vaporization. HBr in the gas fraction was suppressed due to effective fixation of bromine in residue in the form of CuBr.

Abstract The establishment of technological approaches for the defluorination of waste fluoropolymers and recovery of eliminated F^– may contribute to the development of fluorine recycling routes. In this study, we investigated the effects of alkalinity, phase transfer catalyst (PTC) concentration, reaction temperature, and solvent types on the defluorination of polyvinylidene fluoride (PVDF) by alkaline wet processing. The rate of defluorination of PVDF in 4.0 M sodium hydroxide (NaOH) and 50 mM tetrabutylammonium bromide (TBAB) under aqueous conditions reached 89.2%. In addition, the defluorination reaction proceeded faster in solvents such as diethylene glycol (DEG) and triethylene glycol (TEG) than in water because of the high affinity between PVDF and these diols. To investigate the feasibility of developing a fluorine recycling route, the defluorination of a photovoltaic (PV) backsheet and subsequent CaF₂ precipitation from the eliminated F^– was examined. A total of 88.3% of F contained in the PV backsheet was recovered as CaF₂, which satisfied the quality standards of commercial fluorspar. This study demonstrated that alkaline wet processing is effective for the defluorination of PVDF and that the establishment of a F recycling route along the F supply chain may be feasible.

Abstract Recovering fluorine from end-of-life products is crucial for the sustainable production and consumption of fluorine-containing compounds because fluorspar, an important natural resource for fluorine, is currently at a supply risk. In this study, we investigated the feasibility of chemically recycling a fluorine-containing photovoltaic (PV) backsheet for fluoropolymer recycling. Herein, a PV backsheet consisting of laminated polyethylene terephthalate (PET) and polyvinylidene fluoride (PVDF) was treated with different concentrations of sodium hydroxide (NaOH) to hydrolyze the PET layer to water-soluble sodium terephthalate (Na₂TP) and to separate pure PVDF layer as a solid material. Optimized alkaline conditions (up to 10 M NaOH at 100 °C for 2 h) were determined, under which 87% of the PET layer could be decomposed without any significant deterioration of the PVDF layer. The hydrolysis kinetics of PET layer in NaOH could be explained by the modified shrinking-core model. Considering that the mass of end-of-life PV panels in Japan is estimated to increase to approximately 280,000 tons per year by 2036, PV backsheets are attractive candidates for fluoropolymer recycling, which can be effectively achieved using chemical recycling approach demonstrated in this study.

More details Close

Pyrolysis is a promising method to convert biomass and plastic mixture to useful materials. In this work, we investigated the co-pyrolysis behavior of cellulose and polypropylene(PP) mixture. In the presence of PP, yield of levoglucosan was diminished, and the char yield was enhanced. Cellulose did not influence on the results of PP pyrolysis. These findings differ from co-pyrolysis behavior of beech wood and polyethylene(PE) carried out, previously which might be due to the lower thermal conductivity of PP than that of PE and the presence of tertiary carbon atom of PP.

More details Close

Interactions between woody biomasses and plastics during co-pyrolysis of these mixtures have been investigated to recover useful materials. In this work, we researched co-pyrolysis behavior of beech wood (BW) and polyethylene (PE) mixtures at 650 °C. The present work revealed that yield of levoglucosan (LG) and products generated from LG increased because LG condensation was physically suppressed by melted PE. In addition, products generated from PE by BW radical species have lower molecular weight. Furthermore, it implied that PE decomposition was enhanced by water produced from BW.

Chlorine is a by-product of caustic soda (NaOH) production in the soda industry. However, the demand of chlorine is greater than that of NaOH in Japan and overseas. This is a result of the enormous increase in demand for polyvinyl chloride (PVC).In this study, we propose the new concept of a chlorine cycle. Chlorine is problematic in the disposal of PVC. However, chlorine may be recovered from PVC and used to meet the chlorine demand of the soda industry. The aim of this study was to develop the process to complete the chlorine cycle. In this study, we developed the principle of the process of chlorine recovery from PVC. A detailed visualization of domestic chlorine material flow and the quantification of environmental impacts such as energy consumption and greenhouse gas emissions were also conducted. By linking technological development and environmental impact assessment, we were able to derive chlorine recovery conditions that consider the reduction of environmental impacts.

This work investigated pyrolytic interactions between plastic and biomass pyrolyzates during co-pyrolysis of plastic/biomass mixtures to achieve effective recovery of chemical feedstock and fuels. We have revealed several pyrolytic interactions such as enhanced production of levoglucosan from cellulose and methoxyphenols from lignin at slow pyrolysis conditions and enhanced gasification of plastics at fast pyrolysis conditions. These findings will be beneficial to control or maximize product yield and quality from plastic and biomass mixed wastes in the future.

平成27年度の研究計画は、窒素含有樹脂の水蒸気分解による原料回収試験および熱重量分析による反応速度解析であった。そこで、今年度は、窒素含有樹脂であるポリイミドとして代表的なカプトン（デュポン・東レ）を試料に用い、その水蒸気分解挙動を検討した。分解温度を500～900 ℃として水蒸気添加の効果を検討した結果、500 ℃において、水蒸気を添加することで僅かであるが液体生成物が増加した。これは、水蒸気添加によってイミド環が開裂する加水分解反応が進行したためである。700 ℃では、水蒸気雰囲気下においても熱分解反応の影響が相対的に強く、水蒸気の効果は確認されなかった。一方、900 ℃では、炭化したポリイミドの水性ガス反応が進行し、合成ガス（H2+CO）を主成分とする気体生成物および1800 m2/gを越える高比表面積の活性炭を得られることが明らかとなった。気体生成物は約2000 mL/g-sampleであり、そのH2/CO比は1.3であった。熱重量分析装置を用いて、イミド環の開裂が主となる反応温度500 ℃前後において、水蒸気分解の反応速度解析を実施した。その結果、熱分解条件における見かけの活性化エネルギーは276 kJ/molであり、水蒸気雰囲気下では187 kJ/molに低下することを確認した。合成ガスや高比表面積の活性炭を得られた一方で、ポリイミドの水蒸気分解においては、有毒なシアン化水素が生成することも確認された。

今年度は、ポリエチレンテレフイタレート（PET）のベンゼン化の際に用いる酸化カルシウム（CaO）に主眼を置き、テレフタル酸のベンゼン化に及ぼすCaOの性能の影響を検討した。テレフタル酸のベンゼン化に及ぼすCaOの性能を評価するため、炭酸カルシウム（CaCO3）からCaOを調製する際の焼成温度を900 ℃、990 ℃、1050 ℃、1110 ℃、および1170 ℃とし、得られたCaOのBET比表面積、細孔容積分布、および指示薬法による表面塩基度を測定した。焼成温度の増加に伴い、CaOの焼結が進行することが確認され、それらのBET比表面積、細孔容積は温度増加と共に減少した。指示薬法による表面塩基度測定を実施した結果、焼成温度900 ℃のCaOが強い表面塩基度を示した。これらのCaOを、固定床反応装置に供給するテレフタル酸に対してモル比120となるよう充填し、反応温度700 ℃でテレフタル酸のベンゼン化試験を実施した。その結果、ベンゼン収率は僅かにではあるが、焼成温度の増加に伴い増加する傾向を示した。また、活性の高いCaOであるほど、ベンゼンのプロトンを引き抜き、生成したベンゼン同士の二次反応によるビフェニルの生成量が増加した。一方、焼成温度900 ℃以上のCaOを用いた場合、CaOと反応せずに充填層を通過したテレフタル酸が確認された。以上より、テレフタル酸とCaOが効率よく反応するためにはある程度の活性が必要であると同時に、活性の高すぎるCaOは生成したベンゼン同士の二次反応を促進するため、ベンゼン収率が低下する可能性が示唆された。しかし、いずれのCaOを用いた場合でもベンゼン収率・純度に大きな差異は確認されず、PETのベンゼン化に適用可能なCaOの性能は幅広いことが明らかとなった。
