This study addressed the development of a pilot plant for pyrolysis of scrap tires to obtain carbon black and other byproducts. The work was motivated by the goal of contributing to the development and dissemination of knowledge about existing technologies that allow modern economies to transform waste into valuable products, by documenting and discussing an empirical application in Brazil. Thispaper describes the development of a market for steel scrap, pyrolytic oil and carbon black products obtained from a vacuum pyrolysis process. The research work was conducted in Brazil, and was guided by the twofold purpose of reducing the environmental impacts, while gaining economical sustainability. Modern economies increasingly need to devise strategies to address energy generation while preserving natural ecosystems. These strategies include leveraging the use of renewable energy sources. Acknowledging that scrap tires hold an enormous potential as a sustainable energy option, this study aimed to contribute to the development and maturity of eco-friendly processing approaches to realize its full potential. The work involved a preliminary phase concerned with the operation of vacuum pyrolysis of scrap tires at a laboratorial scale, followed by the design of the pilot plant that operated for 10 years, at the time of the study, with a 100 kg/h batch flow. Results show that the yield of the pyrolysis process was 41% pyrolytic oil, 38% carbon black, 12% gas, and 8.9% steel scrap, with a calorific value of 36 MJ/kg per tire. The carbon black was composed of 90% carbon, and the pyrolytic oil was composed of 66% gasoline and 33% other oils, which have higher quality and can be commercialized with a potential profit over 3 million dollars/year.

“…The best ratio between castor and soybean oil was 20% and 80%, respectively, based on physicochemical properties. To increase reaction yield, 2 4 factorial design was performed. Four variables were studied: alcohol:oil ratio, catalyst amount, temperature, and reaction time, and only alcohol:oil ratio and catalyst amount were significant.…”

“…For example, it is difficult to use the same types of oil/fat all year round. The production of vegetable oil is seasonal and as biodiesel production must be conducted in the same area as it will be consumed, associated with biodiesel degradation and stimulation of local production, it is important that all available oils are utilized . Despite the interest in the search for new feedstock for oils to be used in the production of biodiesel, few papers have been published concerning likely oils to use, although it is possible the biodiesel industry may receive new oil mixtures for production purposes …”

Summary Biodiesel is an alternative renewable fuel in the world energy matrix, originating from animal fats and vegetable oils from grains, such as the castor bean cultivated by family farmers in the Brazilian semiarid region. However, the production of biodiesel has some disadvantages. For example, it is difficult to use the same types of oil/fat all year round. In addition, the use of methanol in the biodiesel synthesis and agitation process results in a high consumption of energy. Given this background, this article proposes an alternative biodiesel synthesis using castor oil and peanut oil mixtures, ultrasound‐assisted in an ethylic route. The experimental conditions were optimized utilizing a Box‐Behnken design. The response variable was a biodiesel yield. In this work, it was possible to reduce the ratio of alcohol to oil and thus reduce the energy consumption and increase the mass yield. This permitted the generation of biofuel with lower production costs. Finally, the response surface methodology leads to operational conditions more suitable for the production of biodiesel. In this work, the best conditions were obtained using 0.50% catalyst concentration, 50/50 castor:peanut oil rate, and 5:1 alcohol:oil ratio. These were moderate and suitable conditions for the synthesis of biodiesel in comparison with the works found in the literature, reaching a high yield of 97.93%.

“…O biodiesel é livre de enxofre, não-tóxico, e biodegradável. Reduz a emissão de poluentes gasosos, reduz o aquecimento global, é economicamente competitivo e pode ser produzido por pequenas empresas(Miranda et al, 2018).O Biodiesel surgiu a partir de uma invenção na exposição mundial que aconteceu em Paris no ano 1900. Na ocasião, o Dr. Rudolf Diesel apresentou aos presentes um motor diesel de injeção indireta utilizando óleo de amendoim como combustível (KNOTHE et al, 2006).…”

comparing scenarios with 10%, 15% and 20% of biodiesel in this composition. This comparison was carried out by means of simulation of a computational model developed by the researchers based on the methodology proposed by Sterman (2000). In the definition of the equations and their relations of the simulation model, a time horizon of ten years was considered. The results show that, from a financial perspective, there is a great difference between the different percentages of biodiesel in fuel composition, showing advantages in the use of biodiesel with higher percentage.
