“…In addition, Lee et al (2015) and Rehan et al (2016) studied the potential of using fuel oil produced in pyrolysis for electricity generation in diesel engines. Moreover, many researchers employed the produced liquid oil as transportation fuel after blending with conventional diesel at different ratios (Kumar et al, 2013;Budsaereechai et al, 2019;Gupta et al, 2019;Praveenkumar et al, 2022) Table 2 shows the distillation data of waste PP and waste LDPE fuel oils. These results show the variation of short-chain hydrocarbons and longchain hydrocarbons in the resultant fuel oil.…”

Plastics cause severe environmental and societal issues when post-consumer plastics are discarded in the environment without proper management. Pyrolysis of plastic waste is a promising method for plastic waste management due to its valuable by-products such as fuel oil. The objective of the present study was to pyrolysis waste polypropylene (PP) and waste low-density polyethylene (LDPE) plastics into fuel oil in a low-cost, lab-scale apparatus at the maximum temperatures of 330 °C and 355 °C, respectively, and in turn to assess the physical properties, gross calorific value, density, kinematic viscosity, flash point, ash content, and sulfur content, of resultant fuel oil. Commercially available, recycled grades of LDPE and PP pellets, 70.0 g of each, were obtained, and pyrolysis was done in a lab-scale, low-cost batch reactor. The experiment was triplicated, and the resultant fuel oil was analyzed for physical properties by ASTM standard methods. The properties of resultant fuel oil were also compared with diesel grade criteria. Results revealed that the highest yield of fuel oil was obtained from waste PP at 79.57 wt.% while the waste LDPE resulted at 74.06 wt.% of fuel oil. No wax formation was observed in the waste PP pyrolysis process, unlike in the waste LDPE pyrolysis. The gross calorific values of waste PP and waste LDPE were 12 016 kcal/kg and 11 961 kcal/kg, respectively. It was higher than the standard value of commercial diesel. The distillation results indicated that short-chain hydrocarbon content is higher in the waste PP fuel oil sample than in the waste LDPE fuel oil sample. The results indicated that the resultant fuel oil samples were nearly closer to the diesel grade criteria. Therefore, the fuel oil produced from waste plastics is a viable alternative to traditional fossil fuels, with potential applications in power generation and transportation.

Nowadays road construction is rapidly increasing on-demand to meet several medium and long terms development programs. A huge amount of natural resources, types of machinery and fuels are used in road construction. Using material resources and fuel an efficient manner, reducing in emission of greenhouse gases and controlling various impacts on the environment are important tasks in the road construction industry. In the present research, several environmental impacts related to the construction of asphalt paved highways in Ethiopia have been determined using the Life Cycle Assessment Approach for common pavement materials and construction activities. A deep focus has been given towards the extraction and processing of sand and gravel for preparation of base and sub-base; transportation of these input raw materials; consumption of fuels by various road construction machinery; direct or indirect emissions of carbon dioxide and other pollutants to atmosphere etc. Various suitable methods have been used to calculate the impacts of raw materials, fuel and machinery on various categories such as global warming potential, ozone depletion potential, terrestrial acidification potential, freshwater eutrophication, freshwater ecotoxicity etc. From the investigation, it has been suggested to use recycled materials for substituting gravel as base or sub-base materials and biodiesel for substituting diesel in the transportation trucks and dumpers. These types of new recycled materials may greatly help in assisting the evaluation of sustainable pavement construction. The present case study may help for potential changes in asphalt pavement construction to improve environmental sustainability.

“…O petróleo é atualmente a fonte de energia mais viável e econômica disponível na era atual sendo a melhor escolha para diversos setores e indústrias (FRANÇA et al, 2017). Apesar do alarme sobre a diminuição da oferta de petróleo, há otimismo quanto a inovação em alternativas de queima limpa, como o bioetanol e o biodiesel tanto pelo esgotamento dos combustíveis fósseis como pelos danos ambientais causados, levando ao desenvolvimento de fontes de energias renováveis e ecologicamente corretas e energeticamente eficientes (PRAVEENKUMAR et al, 2022;ANDERSON et al, 2021;ZHU et al, 2011) Os motores a diesel tem muitas vantagens, no entanto, as toxinas liberadas quando o óleo diesel é queimado são uma das principais causas da poluição do ar e um risco significativo de câncer para os seres humanos (ZHENG et al, 2008).Diversos pesquisadores tem estudado combustíveis alternativos em um esforço para encontrar uma solução para o problema (KUMAR; DINESHA; BRAN, 2017;RASHEDUl et al, 2014). O biodiesel é um combustível que pode ser utilizado em motores diesel sem quaisquer modificações, pois é facilmente disponível, ambientalmente benéfico, não tóxico e renovável (KUKANA; JAKHAR, 2022).…”

Com o aumento da população, o consumo de energia vem aumentando progressivamente em todos os setores. A dependência dos combustíveis fósseis tem aumentado devido à necessidade cada vez maior de energia. Por não ser uma energia renovável existe uma preocupação em relação à segurança energética futura. A utilização de combustíveis alternativos como o biodiesel pode ser uma das soluções possíveis para atender à demanda energética futura. O biodiesel é um combustível não tóxico, biodegradável e renovável que pode ser produzido a partir de óleos vegetais, gorduras animais e também de seus resíduos através da aplicação de diferentes técnicas. Embora não tenha natureza alimentar, o cártamo (Carthamus tinctorius L.) pode ser utilizado como matéria-prima para a produção de biodiesel porque seu consumo de óleo é limitado e pode ser cultivado em áreas áridas e secas em todo o mundo. O objetivo da presente da pesquisa consistiu em conduzir a extração do óleo de cártamo por meio de métodos mecânicos, com a avaliação do rendimento do óleo, subprodutos como resíduos sólidos (torta) e subprodutos indesejados (borra). Além disso, buscou-se analisar o rendimento do óleo para sua posterior aplicação na obtenção de biodiesel, utilizando o processo de transesterificação e o rendimento do biodiesel obtido com o a cultivar em estudo. O rendimento médio foi de 13,23% valor considerado baixo pela composição das sementes e estudos anteriores, assim como o rendimento do biodiesel.
