It is increasingly common for laws to restrict the use of a product due to its low sustainability, whether due to the use of finite resources, whether due to damage to human or animal health or any form of damage to nature. A process that consumes more than necessary can also be draining resources in a disorderly way. In the case of civil construction products, at the base of the category is the brick, with its unique physical properties and that has evolved since the beginning of the sector. The evolution of the artisanal method to industrial scale processes is recent, especially with regard to the preparation of raw materials, curing and packaging. Reduce or even avoid water consumption in a process, as well as increasing productivity with less effort in activities, these are sought after in every industrial branch. In this context, this work aimed to evaluate the results of the implementation of an innovation in the production process of ecological bricks, in order to build a new framework for the production process. For this, initially, the conventional production process of this type of bricks was described and characterized, according to current technical standards. In another stage, the research sought to discuss particularities of a new form of production, supported by the literature and evaluated in the form of a single case study, based on the experience of a company located in the Southwest of Paraná-BR. Research procedures included the production of samples of ecological bricks, measured based on quality indicators for compressive strength and water absorption. In addition to the quality of the parts, time and use of resources in the manufacturing process were addressed. In these terms, it is an applied research, with a qualitative-quantitative approach, with documentary origin data and primary data collection, in the context of a case study. Among the main results, there is the favoring in the mixing process with machines that allow the uniform homogenization of cement in moist soils, which results in the reduction of water consumption in the manufacturing process, since it was not necessary to wet the bricks by seven days, as in the conventional method. Another benefit refers to the practicality of a new form of packaging, which eliminates the need to rehandle the bricks for transport, what happened only after 14 days of cure, in the conventional method. Among other aspects, the process resulted in products with quality compatible with the requirements of the current technical standards, in addition to the research illustrating a matrix model for expedited measurement of samples. After analyzing and discussing the perceived improvements, the framework of the new process was structured, presenting it as an innovation for the industry in this segment, called the Alroma Method. Based on the Theory of Perceived Attributes (TAP), innovation in the process was found in relation to that suggested by Brazilian technical standards, which currently regulate the process of preparing the raw material in the reverse order of the innovative process, which consists of drying the soil, crush, sieve and only then mix with the cement. For every thousand bricks produced, in the method with direct packaging, it is possible to reduce water consumption in the production process by up to 110 liters; and in the curing stage, up to 252 liters, totaling savings of up to 362 liters of water. Among other advantages are the shorter process time, with machines that allow the homogenization of cement in moist soil and pressing under ideal humidity conditions; in addition to providing less physical effort, the machines ignore the prior drying and crushing of the soil, sieving only in the last stage of preparation of the mixture; therefore, pressing with more moisture eliminates irrigation of the bricks and reduces the curing time to use the product by packing the bricks immediately after pressing. The sustainability guidelines evoke creativity to make better use of our resources, therefore, engaged with this need, the scientific rigor of the research ensured impartiality and brought to the public knowledge improvements and advances for the sector. Novos produtos e novos processos ganham o mercado ao tempo em que medidas de preservação do meio ambiente se intensificam. É cada dia mais comum as leis restringirem o uso de um produto por sua baixa sustentabilidade, seja devido à utilização de recursos finitos, seja pelos danos à saúde humana, animal ou qualquer forma de dano à natureza. Um processo que consome além do necessário também pode estar esvaindo recursos de maneira desordenada. Tratando-se de produtos da construção civil, na base da categoria está o tijolo, com sua singularidade de propriedades físicas e que evolui desde os primórdios do setor. É recente a evolução do método artesanal para os processos de escala industrial, ainda mais no que se refere ao preparo de matéria-prima, cura e embalagem. Reduzir ou até mesmo evitar o consumo de água em um processo, assim como aumentar a produtividade com menor esforço nas atividades, são intensões almejadas em todo ramo industrial. Inserido nesse contexto, este trabalho teve como finalidade avaliar os resultados da implantação de uma inovação no processo de produção de tijolos ecológicos, de modo a construir um novo framework do processo de produção. Para isso, inicialmente, foi descrito e caracterizado o processo convencional de produção desse tipo de tijolos, segundo as normas técnicas vigentes. Em outra etapa, a pesquisa procurou discutir particularidades de uma nova forma de produção, respaldada pela literatura e avaliada sob a forma de estudo de caso único, a partir da experiência de uma empresa, localizada no Sudoeste do Paraná-BR. Os procedimentos de pesquisa incluíram a produção de amostras de tijolos ecológicos, aferidas com base nos indicadores de qualidade quanto à resistência à compressão e absorção de água. Além da qualidade das peças, foi abordado o tempo e o uso de recursos no processo de fabricação. Nesses termos, é uma pesquisa aplicada, de abordagem qualitativa-quantitativa com dados de origem documental e coleta de dados primários, no contexto de um estudo de caso. Entre os principais resultados, destaca-se o favorecimento no processo de mistura com máquinas que permitem a homogeneização uniforme do cimento em solos úmidos, do que decorre a redução do consumo de água no processo de fabricação, posto que não foi necessário molhar os tijolos por sete dias, como ocorria no método convencional. Outro benefício refere-se à praticidade de uma nova forma de embalagem, que dispensa o serviço de remanusear os tijolos para transporte, o que ocorria apenas depois de 14 dias de cura, no método convencional. Entre outros aspectos, o processo resultou em produtos com qualidade compatíveis às exigências das normas técnicas vigentes, além da pesquisa ilustrar um modelo de matriz para aferição expedita de amostras. Após analisar e discutir as melhorias percebidas, foi estruturado o framework do novo processo, apresentando-o como uma inovação para a indústria desse segmento, denominado Método Alroma. Embasado na Teoria de Atributos Percebidos (TAP), foi constatada a inovação no processo em relação ao sugerido pelas normas técnicas brasileiras, que regulam atualmente o processo de preparação da matéria-prima pela ordem inversa do processo inovador, que consiste em secar o solo, triturar, peneirar para só então misturar com o cimento. No método Alroma é possível reduzir o consumo de água no processo de produção em até 110 litros; e na etapa de cura, em até 252 litros, totalizando uma economia de até 362 litros de água para cada mil tijolos produzidos. Entre outras vantagens, estão o menor tempo de processo, com máquinas que permitem a homogeneização do cimento em solo úmido e prensagem nas condições ideais de umidade; além de proporcionar menor esforço físico as máquinas ignoram a secagem e trituração prévia do solo, peneirando apenas no último estágio do preparo da mistura; portanto, prensando com mais umidade dispensa a irrigação dos tijolos e reduz o tempo de cura para utilizar o produto embalando os tijolos imediatamente após a prensagem. As diretrizes de sustentabilidade evocam criatividade para aproveitar melhor nossos recursos, portanto, engajado a essa necessidade, o rigor científico da pesquisa garantiu imparcialidade e leva ao conhecimento público melhorias e avanços para o setor. 2021-11-22T12:39:19Z 2021-11-22T12:39:19Z 2021-08-16 masterThesis RESTELLI, Rogério Expedito.

New products and new processes gain the market at the same time that measures to preserve the environment are intensifying. It is increasingly common for laws to restrict the use of a product due to its low sustainability, whether due to the use of finite resources, whether due to damage to human or animal health or any form of damage to nature.
