“…É importante que a manipulação e comercialização sejam executados de maneira que garanta a saúde do consumidor final. Os peixes são mais susceptíveis à decomposição por enzimas e bactérias devido "a menor quantidade de tecido conjuntivo; elevada atividade de água; gordura facilmente oxidável e pH próximo da neutralidade, levando a alterações de natureza física e química, ocasionando riscos à saúde do consumidor" 3 .…”

Esta pesquisa descreve as condições higiênico-sanitárias na comercialização de peixes no mercado público do município de Chaval – Ceará. Pesquisa de abordagem qualitativa, do tipo estudo de caso, tendo como espaço de pesquisa o mercado público de Chaval-Ceará, realizada em janeiro de 2023. A coleta de dados baseou-se em observação direta e uso de instrumento de checklist. Para análise dos dados, seguiu-se o pensamento de Bardi, onde a discussão está construída por meio de embasamentos teóricos. Constatou-se as conformidades e não conformidades, destacando-se as más condições de conservação e higiene das mesas, o risco de contaminação por poeiras e outras partículas em suspensão, isopores com gelo com sujidade, armazenamento inadequado dos peixes, ausência de comprovante de controle de pragas. As evidências demonstram a urgência de treinamento para vendedores e adequação da estrutura física do local.

“…As for organic waste recycling, waste from the Brazilian fishing industry was the object of research on the CE, and significant disposal of nutrient material was detected. This is important waste in the ecosystem in which it is inserted, demanding attention and investments for its adequate disposal (Machado et al, 2020). Another topic addressed is the growing electronics industry, which has an impact on the material supply chain.…”

Sustainable development has been pursued by organizations around the world ever since environmental and social issues were introduced into institutional agendas. In the various sectors of the economy, the factors that influence sustainable decisions are multidisciplinary and systemic, and address the concept of Circular Economy (CE). This study aimed to develop a method to measure the level of commitment of companies and sectors to CE. The method allows investigating institutional factors associated with sustainable development and assessing the depth of CE practices. A circularity index is originated that can assist decision makers in the development of specific strategies, investment plans, and policies to guide organizations towards the achievement of a CE. The proposed method was then applied to 75 Brazilian companies recognized for their sustainability initiatives, analyzing practices associated with CE actions, as well as their depth. The results, using the Analytic Hierarchical Process (AHP), indicate that the sectors analyzed do not have a significant difference among them and that the majority of the companies analyzed (80%) do not practice any circular action despite claiming the opposite. Therefore, CE is still incipient in Brazil. The application of the proposed method to a large sample showed its potential for global use, and that it can also be employed to guide actions of single companies or entire sectors towards sustainable development using a CE path.

The development of materials that are highly degradable at the end of their life cycle helps reduce the volume of solid waste disposed of in landfills. This study aimed to produce composites from cellulose and paper residues as reinforcing fibers and from thermoplastic starch (TPS) as a matrix to analyze the effect of exposure to natural weathering in the environments of two Universities, one in Brazil (Universidade Feevale) and the other in Finland (HAMK). During the test period, the season in Brazil was summer, with high temperatures and solar radiation; in Finland, the season was winter, with negative temperatures, high air humidity, and snowfall. The materials were prepared using the tape-casting method and characterized by Dynamic Mechanical Analysis (DMA) and Thermogravimetric Analysis (TGA), having been subjected to the weather for 0, 28, and 42 days at Universidade Feevale and HAMK. At the end of each period, they were characterized by Scanning Electron Microscopy (SEM) and photographs. The results showed that the thermal stability of the composites was better compared to TPS and cellulose, and superior mechanical properties were shown in the cellulose-based composite. Thus, heterogeneous mixtures emerged from the addition of fibers to the polymer matrix. After the environmental exposure, the visualization of the micrographs and photographs indicated that the samples exposed in the two environments were brittle, shrunken, yellowed, and cracked. It was also verified that the samples exposed at Universidade Feevale suffered greater environmental degradation, and the incorporation of fibers in the composites delayed this effect at the two study sites.
