The adoption of management practices that reduce water losses is essential to conserve moisture and improve soil temperature, especially in arid and semiarid environments of the Brazilian Northeast, characterized by high evapotranspiration and the adoption of irrigation with saline water, which harms growth and yield of commercial crops. Given these factories, an experiment was conducted in Nova Floresta, Paraiba, from August 2010 to February 2011 in Oxisoil, in order to evaluate the production of bell pepper and soil moisture in grooves with side trim, and application of biofertilizer and mulch cattle. The experimental design was randomized blocks with four replications using a factorial 2 x 2 x 2 for the ground beef with and without biofertilizer, with and without residues of sisal fiber (Agave sisalana), with and without the side facing the grooves, to reduce lateral water losses by infiltration of water with polyethylene plastic film. From the results, the lining of the lateral grooves provided higher values of soil moisture, number of fruits, fruit mass, plant production and productivity, bell pepper plants. It was also found that the combination of biofertilizer and mulch the ground beef remained wetter in the first 15 cm depth.

This special volume of the Journal of Cleaner Production is comprised of articles presented at the 3rd International Workshop Advances in Cleaner Production held in Sao Paulo, Brazil, in 2011. The content underscores the recognition of the pressing and inescapable need for making changes from unsustainable to sustainable production and consumption patterns. The 48 articles from 15 countries provide different, but complimentary approaches to help industrial and societal sectors in advancing on their paths towards sustainability. Initiatives and challenges are included, which systematically address problems affecting raw material changes, technological modifications, product and policy changes. The findings range from proposals for alternative uses of wastes, substitution of raw materials for environmentally friendlier substances, optimization of industrial processes by source reductions of wastes and emissions and documented economic and environmental advantages of a wide array of initiatives. The roles of operational and managerial practices are also stressed, highlighting the role of diverse stakeholders as promoters of implementation and internalization of innovative cleaner technologies within companies. Systemic assessment tools are employed and experimented with in order to more effectively evaluate the environmental performance of systems on the biosphere scale. The methodological procedures and proposals presented can help in the design and management of production systems, for governmental and corporate policy development, for implementing and monitoring CP Programs, prevention and mitigation strategies, and evaluation of the outcomes of CP initiatives in the production and service sectors.

Displays the Information Literacy as a method of training for access, evaluation and use of information, which has become, increasingly, the raw material indispensable for intellectual autonomy. Presents the articulation possible - and necessary - between Information and Cultural Competence in School, with emphasis on their relationship. Search is on School Culture, contexts for insertion of procedures developed by the Information Literacy, considering the dimensions of the organization, interpretation and knowledge production. It points out the advantages to realize the Culture School, through practical philosophical context, to support action planning, establishing, in the educational environment, actions related to the development of Competency Information. We used participation research action in the context of a public school in Campo Grande-MS, the research subjects were students of the 6º and 7º grades and their teachers. Data collection took place through observation and interviews relating the development of competencein Information and teaching practices It is noteworthy that this kind of responsibility if developed without an understanding of school culture, becomes a rambling and disjointed practice whose outcomes are at risk of not being achieved.

Obtaining accurate estimates of the volume of stacked wood is important in view of the increasing value of wood as raw material. Therefore, the forest companies have become increasingly concerned about the methods currently used to convert cubic meters for stereo. In this context, emerged the need of optimizing the measurement process and accuracy of the volume of stacked wood. For this, companies have been testing methods with greater efficiency, speed and low operating cost. Existing methods made through approximate equations, and also by determining the conversion factor, called the stacking factor (Fe), are questioned, due to errors and inaccuracies. The use of digital photographs is an alternative method that would minimize operator intervention, allowing greater control and speed the process, thus eliminating part of the imprecision of the traditional method. The use of the method is viable, due to present an error of about 10% while traditional methods showed an error of 17%

Among numerous studies about the selective collection of solid waste and cooperatives of recyclable materials, this research aims to contribute with the study of these problems from the geographic space. As the world population increases, the issue of solid waste becomes increasingly worrying, due to new consumption patterns that create larger amounts of waste, especially in the urban centers. The recycling appears to be the best solution for this problem since most materials that are currently sent to landfills would become raw material for new products. The Triage Centers performs an important role in this process because they are responsible for sorting, packing and selling the materials arising from the selective collect, so it is necessary to analyze the places where these steps are performed. This study intend to examine the location and distribution of these enterprises in the city of São Paulo in order to provide support for the mitigation of impacts, both environmental and social, from their location, as well as provide support for the expansion of selective collection program in the city. The choice for studying this area was due to the curiosity of investigating the inefficiency of the recycling program in the city of São Paulo, which currently recycles about 1% of all household solid waste collected. Therefore, from a historical survey of the city's recycling programs, technical visits, interviews with responsible agencies and also analysis of the Triage Center's frameworks based on the guidelines from the municipal legislation, it will be evaluated the problems faced by the program for its expansion

Due to environmental concerns and the current legal requirements, companies are looking for ways to reconcile economic growth with environmental preservation. The purpose of this project is to show the stages of implementation of ISO 14001 in a chemical company and propose changes in chemical procedures creating goals to be achieved. In this paper, the study for the implementation of ISO 14001 is in Viapol ltda., where the lack of environmental management can cause enormous impact to the environment and may generate air, soil and water pollution. The project resulted in a mapping of all the processes and a broad survey of waste and emissions, generating proposals to change some of the processes and and creating programs to achieve the goals and objectives proposed in the Environmental Policy. Adopting an environmental management system (EMS), the company will reduce costs by decreasing the amount of raw material used, shooting down on waste disposal and the amount of it, and increasing productivity. By committing to the implementation of the EMS, companies will be demonstrating a proactive approach to environmental issues and enrich its image to consumers’ point of view

This paper analyzes the evolution of the sugar cane plantation area in the State of São Paulo in the last ten years. It presents a concise report about the history of this raw material in the country and describes how the sector relating to sugar cane was before the economic deregulation and what changes occurred after 1990, emphasizing the territorially expansion occurred in the State of São Paulo. The paper concludes that the expansion of the sector relating to sugar cane occurred much more territorially than through productivity gains, considering that these ganis were bigger in the State of São Paulo, and that the economic deregulation left a legate of heterogeneity in this sector
