“…The different types of hydrocarbons present in the pyro-oil were identified using 1 H and 13 C NMR analysis. This analysis estimated the carbon chain like olefin, aromatic, and paraffin present in the fuel samples as per our previous study (Alawa and Chakma 2022a ). The 1 H and 13 C NMR spectra of the waste HDPE pyro-oil are depicted in Fig.…”

“…The BSFC was reduced by ~ 8.76% and ~ 8.4% at 16.2 CR and 14.81% and 17.24% at 15.1 CR, respectively, for CDPO10 and CDPO20 under the optimum condition of BMEP. The low fuel consumption, when run with PO composite samples, is attributed to the low viscosity and high calorific value of the PO blended fuel samples (Alawa and Chakma 2022a ; Padmanabhan et al 2022 ). However, fuel consumption increases when the compression ratio (CR) increases from 15.1 to 16.7—which was also reported by other studies (Alawa and Chakma 2023 ; Rajak et al 2022 ).…”

“…The CO 2 emission is the result of complete combustion by a reaction between hydrocarbons and oxygen in the presence of air in the combustion cylinder. Therefore, the higher generation of CO 2 with PO blends essentially indicates of reduction in CO emission when PO is used with CD (Alawa and Chakma 2022a ; Rajak et al 2022 ; Nadanakumar et al 2021 ).…”

“…If the current demand for plastic materials continues, the estimated amount of plastic production will double by 2025 and three folds by 2050 (Kartik et al 2022 ). On the other hand, energy security is one of the major concerns of today’s world, and the demand for energy has significantly increased with the growth of the population and industrialization (Alawa and Chakma 2022a ). Moreover, approximately 4% of fossil fuel comprising of natural gas and other low fraction of petroleum products is utilized to produce plastic—which indirectly affects the energy requirement (Kartik et al 2022 ).…”

“…Moreover, approximately 4% of fossil fuel comprising of natural gas and other low fraction of petroleum products is utilized to produce plastic—which indirectly affects the energy requirement (Kartik et al 2022 ). In the last few decades, it has been reported that pyrolysis is one of the clean and most efficient techniques for the conversion of waste plastic materials into valorized hydrocarbon products in the form of liquid fuels (Alawa and Chakma 2022a , 2023 ; Padmanabhan et al 2022 ; Rajak et al 2022 ). However, the quality of the products may vary depending upon the processing technique of waste plastic materials.…”

Waste management and mitigation is the primary necessity across the globe. The daily use of plastic materials in different forms emergence the plastic pollutions, and it has been significantly increased during the COVID-19 pandemic. Thus, mitigation of waste plastics generation is one of the major challenges in the present situation. The present study addressed the conversion of waste plastics into value-added products such as liquid hydrocarbon fuels and their application in reducing greenhouse gas emissions. A comprehensive investigation has been performed on engine performance and combustion characteristics at various compression ratios and PO blending. The effect of liquid fuel blending with commercial diesel was investigated at three different compression ratios (15.1, 16.2, and 16.7) under various BMEP conditions. The results revealed that blending of liquid fuel produced from waste plastic can improve the BTE significantly, and the highest 35.77% of BTE was observed for 10% blending at 15.1 CR. While the lowest BSFC of 5.77 × 10 −5 kg/kW-s was estimated for 20% PO blending at 16.7 CR under optimum BMEP (4.0 bar) conditions. The investigation of combustion parameters such as cylinder pressure, net heat release rate, rate of pressure rise, and cumulative heat release showed that it increases with the compression ratio from 15.1 to 16.7. At the same time, the emissions of CO, CO 2 , and unburnt hydrocarbon was decreased significantly. The economic analysis for the present lab-scale study estimated that approximately ₹12.17 ($0.15) profit per liter is possible in the 1st year, while the significant profit starts from the 2nd year onward, which is in the range of ₹59.78–₹84.48 ($0.75–$1.07) when the PO is blended with CD within the permissible limits as per the norms.

The components’ lightweighting has been pursued, especially in the transport industry, for greenhouse gas reduction. Topology optimization, being able to allocate the material within a provided design space, is a mathematical method that can support the design of lightweight components, preserving, at the same time, their mechanical performances. In this paper, a standard shape of a component, specifically an automotive bracket, was topology optimized by estimating the impacts of the new designs from an eco-friendly point of view. A subtractive, an additive and a casting manufacturing process were considered as possible manufacturing routes achieving an optimized geometry of the component for each of them. The topology optimizations were performed considering each processes’ peculiarities, introduced as constraints. Same strength for a given set of loads and boundary conditions was the target of each analysis. The component’s lightening can be considered environmentally friendly just after assessing the impacts associated with all the stages of the product’ life cycle. Indeed, each phase of the product’ life cycle can be affected, differently, by the performed topology optimization taking into account the peculiarities of the employed manufacturing process. The overall considerations on the most environmentally safe strategies can, therefore, change according to the specificities of the optimized shapes. The topology optimization showed its utmost potentiality, from a sustainable point of view, if applied to additive manufacturing techniques for the advantages arisen by the capability to manufacture complex shapes benefiting also of reduction time process owing to less material to be deposited.
