The objective of this paper is to describe a business model of a multidisciplinary junior enterprise that offers products and services. It starts from the identification that there are no multidisciplinary junior enterprises in the Federal District with courses in different knowledge areas; junior enterprises offer only services; there are no examples in the literature of how organizations that work with different levels of education can benefit from the performance of students from technical courses in a junior enterprise without being junior entrepreneurs. The description was based on the logic of the business model. The most important choices in the business model of Olaria Junior Enterprise were: institutional support via coproduction; multidisciplinarity; offer of products and services; development of partnerships; participation of students of technical courses in the junior enterprise; competitive prices and sustainable development. The paper seeks to contribute to the process of implementing junior enterprises in educational organizations. [ABSTRACT FROM AUTHOR]

Civil Construction is responsible for consuming large amounts of the non-renewable natural resources and generating significant environmental impacts, which begin with the extraction of the raw material for construction materials manufacturing, and extend to the end of the life cycle of the buildings. In this context, the development of more sustainable building materials is necessary as a way to mitigate the environmental impacts caused and contribute to the sustainable development of the sector. This paper brings the development of concrete bricks for interlocking pavement, manufactured from the addition of PET (Polyethylene Terephthalate) waste replacing part of the natural aggregates. For this, dosage studies were carried out in order to determine the dosage for bricks manufacturing. The bricks were produced and tested in order to verify their compression strenght and water absorption. At the end, the production costs of these bricks were estimated based on the SINAP 2015 table. The results showed that the developed bricks met the technical standard requirements for their use. However, in terms of costs, these have proved to be slightly more expensive than conventional parts. [ABSTRACT FROM AUTHOR]

Brazilian law prohibits any formally unauthorized human x fauna interaction, except the slaughter of wild animals to satisfy the hunger of the poor. A set of traditional activities (hunting, capture, alimentary consumption, sale and possession of wild animals), underlying specific modes of sociability and lifestyles that diverge from the established rules, is, thereby, criminalized. Recognizing the impreciseness of the juridical categories "legal" and "illegal", the paper criticizes their absorption by the scientific discourse, and proposes to replace them by categories based on the rationality of the agent interacting with the fauna: close or far, in successive degrees, from the market logic. By revealing the diversity of situations so far indistinctly seen as crimes against nature, such categories give prominence to marginalized groups, promoting their recognition as legitimate actors in the interlocution with scientific research and with participatory environmental management programs.

This paper aims at verifying whether the selection process used by the City of Santa Maria/RS provides sustainability to the local associations of waste collectors. The research is characterized as descriptive, case study, one based on literature review and field survey. For data collection the techniques used were questionnaire and systematic observation. The results show that waste have not been properly separated by the local population since large volumes of non-recyclable ones are found in the associations. This factor can be reversed with dissemination of information and education, emphasizing that the selective collection is an ecologically correct practice, since it avoids the contamination of soil and water, thuscontributing to planetary sustainability. The local associations confirm that the waste selection process contributes to local sustainability. It can be concluded that the selection process of wastecollection undertaken by the City Hall provides sustainability to the associations and also to santa-marienses, since it contributes to the environment and as well as to the improvement of the quality of life of the local population.
