Besides good successes in recycling PET (No 1) and HDPE (No 2), most of them end up in landfills or waterways and oceans. Even recycling of plastic by mixing them with virgin plastic has problems, as they contain large amounts of pharmaceuticals and other undesirable chemicals. One of the desirable ways to chemically recycle a plastic is to take it back to its starting monomers, which can then be re-polymerized into virgin plastic—a circular recycling. A polyester (PET) polymer can be hydrolyzed back to diacids and diols, and after cleaning, polymerized back to PET with the same characteristics as the original polymer. There are catalytic pyrolytic ways to produce naphtha (C<sub>4</sub>–C<sub>7</sub>) that can be a starting material for ethylene and propylene to be repolymerized to PE and PP. Inductively coupled depolymerization of plastic can, under the right conditions (Eco Fuel Technology, US Patent 9 505 901), take the polymer all the way to its monomer (85–90 + % yield). Mixtures of plastic can be reacted, and the resulting ethylene, propylene, or styrene can be separated to get pure monomers that can be re-polymerized. This will be a true circular chemical recycling and this paper will propose ways to scale up the process to industrial scale. This cycle can be repeated indefinitely and the process by itself does not add any CO<sub>2</sub>.</p>\u0000 </div>","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"7 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.70021","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Innovative fiber identification and pre-processing solutions are needed to enhance the efficiency and efficacy of Materials Recovery Facilities. Various textile scanning technologies are available on the market, with Near-Infrared Spectroscopy (NIR) emerging as the most promising and market-ready option due to its wide use in solid waste and recycling contexts.

The WCFF samples were downsized, and four different filler size ranges were sieved using a series of mesh sizes from 4 to 0.85 mm. The WCFF/PP composites were then compounded at 20 wt.% loading of WCFF using a twin-screw extruder. Incorporating WCFF increased the tensile strength to 41.28 MPa and the modulus to 3207 MPa, accounting for 28% and 38% enhancements, respectively. Interestingly, the greatest improvements were associated with the nonsieved WCFF case, and the sieved WCFF fibers provided only marginal enhancements over virgin PP. The outperformance of nonsieved WCFF was attributed to the synergistic reinforcement of hybrid fibers and fines as well as the maintenance of longer fibers in the system. However, the strain at break and impact strength of PP decreased after introducing WCFF. Moreover, the complex viscosity and storage modulus increased with an increase in the filler size, due to the formation of a more effective percolative network. The PP's crystallinity exhibited a relatively strong dependency on the sieving, where WCFF samples with short-aspect-ratio fillers promoted the crystallinity significantly. It was also found that the WCFF degradation onset temperature increased once it was incorporated into PP. This study suggests that waste cellulosic feedstocks can be utilized as a reinforcement without additional sieving to manufacture high-performance and cost-effective composites.</p>","PeriodicalId":87290,"journal":{"name":"Journal of advanced manufacturing and processing","volume":"7 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/amp2.70022","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process was modeled using Aspen Plus for energy and mass balance and Aspen Process Economic Analyzer for capital cost estimations, with additional manual calculations for operating costs. Economic viability was assessed through net present value (NPV), internal rate of return (IRR), and Minimum Fuel Selling Price (MFSP). Results show that recycling polypropylene via catalytic pyrolysis is economically viable, with a NPV exceeding $330 million and an IRR of 29.6% over a 30-year lifespan. The base case (300 kt/year) demonstrates the most promising financial viability, with high IRR and favorable ROI. Sensitivity analysis highlights the impact of market factors and operational costs on the economic viability of the process. Equipment cost breakdown shows that the “Storage” area, particularly the costs associated with hydrogen storage, is a significant contributor to the total capital investment.
