The leather footwear industry is an important sector in the Brazilian economy. The tannery industry accounted for $ 2.05 billion to exports in 2011, which represents a contribution of 6.86% to the Brazilian balance of trade. However, it is a highly polluting industry generating highly toxic and hazardous waste. Therefore, it is extremely important to search for environmental management actions that allow a cleaner production and waste recycling to prevent its discharge into the environment resulting in the deterioration of nature and quality of human life. Thus, based on a literature review and exploratory research, this study consisted of an analysis of some environmental management actions adopted by the leather industry in Franca - SP verifying if the industries have certifications or follow standards that characterize a responsible environmental management. This study is justified by the fact that tanneries and footwear industries produce highly hazardous waste, and therefore environmental actions are necessary to treat the waste effectively in order to minimize its environmental impacts. The literature review and empirical research conducted demonstrated the development of new techniques and technologies aiming at mitigating the impacts of leather waste in the environment. These actions are crucial for companies to remain competitive and focused on sustainability in this rapidly growing market.

The objective of the present study was to evaluate changes in chemical characteristics of soil and yield response of lettuce fertilized with organic compounds from waste and/or raw materials. Treatments were arranged in a randomized block design in a 5 x 4 factorial scheme, with five types and four doses of organic compounds, with four replications, applied to plants grown in pots for 35 days under greenhouse conditions. In the soil, the evaluated variables were: organic matter content, nutrient content -P, K+, Na+, Ca2+ and Mg+2, potential acidity (H+ + Al3+), sum of bases (S value), cation exchange capacity (CEC), base saturation (V%) and pH. In plants, dry matter yield of shoot was assessed. The addition of organic compounds increased the dry matter yield of the lettuce and organic matter content in soil, favoring the increase of phosphorus and exchangeable sodium in soil, also, increase in calcium and potassium were observed, with use of some compounds. Compounds 3 (domestic, urban and industrial residues) and 4 (Commercial Composto - Greenworld), mainly, improve the chemical characteristics of soil and reduce potential acidity.

The issue of water scarcity, besides being a relevant and contemporary environmental problem, can be characterized as a social phenomenon, the result of inadequate cultural practices. As such it can be studied by Behavior Analysis, more specifically, from the point of view of selection by consequences. In this context, our objective was to identify if campaigns and programs of water conservation are consonant with Behavior Analysis’ principles on how to change and control individual behavior in the cultural dimension. Overall, data indicate the absence of contingent reinforcement on behavior of water waste and conservation and the presence of mentalistic practices, in contrast with the foundations of Behavior Analysis, especially with regard to the logic of selection by consequences.

The study of the generation of landfill gas contributes to the understanding of the relationship between gas production and other parameters, such as time of disposal of waste and moisture (rainfall) and, thus, can subsidize the viability study for energy. This study aims to evaluate the interference of the time of disposal of waste and moisture (rainfall) in the production and composition of biogas generated at the landfill in Rio Claro - SP. As a result it was observed that for the landfill studied, the average percentage of methane in biogas ranged from 49.9% to 54.7%. It was found that moisture (rainfall) and the time of waste disposal are parameters which do not cause significant changes in methane concentration in biogas. However, when analyzed the flow of biogas, which had the maximum average value of 152.86m3/h and minimum average value of 15.47m3/h was observed great interference of moisture (rainfall) and the time of disposal of waste, because well of gas located in newer areas of the landfill showed higher values of flow rate than the areas where the landfill was the beginning of the arrangement. The same way, it was observed that in the dry season flow of biogas decreased in all drains gas analyzed

Health care waste (HCW) is the type of waste that results from activities performed in health care services during care provision to humans or animals. Presently, according to RDC 306/04, issued in 2004 by Anvisa, and Resolution no. 358/05, by CONAMA, waste groups have the following classification: Group A (biological waste), Group B (chemical waste), Group C (waste containing radionucleotides), Group D (common waste) and Group E (piercing and cutting waste). In Brazil, 149 tons of wastes are collected every day, and HCW corresponds to approximately 1% to 3 % of that total. An efficient way to adequately manage HCW is through the Health Care Waste Management Plan (HCWMP), and it is possible to reduce the risk posed by certain materials in addition to ensuring disposal in an ecologically correct and economical fashion. According to the Pan-American Health Organization (PAHO), the management process enables health care establishments to adequately manage waste. Hence, there is greater control and reduction in the health risks caused by infectious or special waste, in addition to facilitated recycling, treatment, storage, transport and final disposal of solid hospital waste in an environmentally safe fashion. To evaluate the management of HCW of Groups A and D from the Intensive Care Unit of the University Emergency Hospital - FMB - UNESP in the city of Botucatu according to the guidelines presently in force. The waste flow was followed up, and during four random days in the month of September 2011, waste was quantified by estimating daily and monthly values, according to its classification. : In 2011, the University hospital has produced an average of 57,676.8 kg/month of biological and common waste. By adding Groups A and D, during the four days, approximately 209.8 Kg of waste (202.2 Kg of Group A and 7.6 Kg of Group D) were produced in the establishment under study, which...

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
