The effects of the dietary substitution of dry corn by high-moisture corn grain silage (HMCGS) were evaluated on the performance, nutrient digestibility and serum biochemical parameters of broilers reared in an alternative production system and submitted to different environmental temperatures. A total of 288 one-day-old male Cobb chicks were distributed according to a randomized block design in a 3x4 factorial arrangement: three environmental temperatures (hot, thermoneutral or cold) and four levels of HMCGS in substitution of dry corn (0%, 20%, 40% or 60%). The acid analysis showed that the evaluated HMCGS contained average percentage values of ethanol, lactic acid, and acetic acid (expressed in 100% of dry matter) of 0.7690, 2.7320 and 0.0249%, respectively. Propionic and butyric acids were not detected. Dry corn and HMCGS presented pH values of 5.8 and 3.3, respectively. The inclusion of HMCGS reduced dietary pH, as shown by the values of 5.7, 5.4, 5.1 and 4.8 recorded for the diets containing 0%, 20%, 40% and 60% of HMCGS, respectively. There was no significant interaction between diets and environmental temperature. HMCGS may replace up to 40% dry corn in broiler diets when performance, triglyceride levels, and HDL-cholesterol ratio is considered, and up to 60% when nutrient digestibility is evaluated. High environmental temperature impairs broiler performance, nutrient digestibility, and serum biochemistry, demonstrating the influence of environmental temperature on broiler metabolism and performance.

The appropriate use of computer aided technologies, allied to the concepts and design guidelines, grounded in biology, stimulated the development of a solar toilet, able to convert human waste into compost, rich in nutrients for use in gardens, farms and small farms. This transdisciplinary approach is presented as a necessary tool to be used in academia, integrating and developing activities previously disconnected. The solar toilet also called green bathroom, combines the most modern concepts and technologies of computer-aided design, design, selection of materials and microbiological control, reaching biologically correct and safe composting of waste, ensuring the viability of the project terms of cost, deployment, use and environmental safety, such as supporting sustainable development. It is also planned to install a pilot project in a small community with the aim of assessing its implementation and use as a complementary activity and university extension.

Introdução: O Laboratório de Design Solidário (Labsol) é um projeto de extensão criado em 2007 que tem como objetivo aperfeiçoar e revitalizar objetos artesanais e arranjos produtivos locais, baseando suas atividades no tripé conceitual: ecodesign, sustentabilidade e economia solidária. O LabSol visita grupos de artesãos, analisa seus produtos, métodos de produção e matérias primas e a partir daí, cria-se projetos e protótipos. O Laboratório conta com a atuação de alunos de Relações Públicas desde 2009 e estes têm como função promover ações de/para aprimoramento da comunicação interna e externa, além da parte burocrática e análise de propostas e projetos. No ano de 2011, ocorreram quatro exposições de produtos feitos pelo LabSol. Em cada uma destas exposições, o papel do profissional de RP foi fundamental, pois avaliou os convites, verificou a abrangência de cada público, a relação entre o projeto e os eventos, e tornou possível a sua efetiva realização. Objetivos: O estudo tem como objetivo analisar a validade e o alcance das exposições do Labsol no primeiro semestre de 2011. As exposições ocorreram no evento “Ecorreto” em 07 e 08 de maio; no Festival da Rádio UNESP em 26 de maio; no projeto “Perspectiva” – projeto de extensão da UNESP – em 01 de junho; e na XII Semana do Meio Ambiente de Bauru no Horto Florestal da cidade em 05 de junho. Métodos: As exposições aconteceram por meio de convite dos organizadores dos eventos e se deram através da exibição dos produtos, criados para os grupos de artesões, em pedestais individuais ou em mesas com produtos e cartazes explicativos. A análise será baseada no número de expectadores de cada evento e no interesse do público em relação ao projeto e aos produtos. Resultados: O público de interação em cada evento variou em numero de expectadores. O Festival da Rádio UNESP, contou com uma média de mil e duzentos; a Semana Integrada do Meio Ambiente, cento e cinqüenta; o “Ecorreto”, quinhentos expectadores (durante a exposição e através do site, onde estão fotos e informações sobre o evento); e o Projeto Perspectiva, realizado na cantina da Faculdade de Engenharia da Unesp, não foi mensurado, porém, alcança principalmente os alunos de período vespertino e noturno dos quatro cursos desta faculdade por ser espaço de fluxo constante de alunos. Cada uma destas exposições foi acompanhada pelos RPs. Durante as exposições, diversas pessoas se interessaram pelo trabalho e, conseqüentemente, perguntaram sobre o Laboratório, demonstrando grande interesse. Acredita-se que por meio destes interessados, a informação sobre o trabalho é multiplicada e, portanto, o conhecimento sobre o projeto alcança maior amplitude. Divulgando não apenas o projeto, mas principalmente o tripé conceitual sobre o qual se apoia.

The purpose of this paper is to propose a definition of the term “green/environmental innovation”, based on a systematic literature review. Design/methodology/approach– The literature review conducted in this research was based on papers published in ISI Web of Science and Scopus databases. Findings– Environmental innovations are organizational implementations and changes focusing on the environment, with implications for companies’ products, manufacturing processes and marketing, with different degrees of novelty. They can be merely incremental improvements that intensify the performance of something that already exists, or radical ones that promote something completely unprecedented, where the main objective is to reduce the company's environmental impacts. In addition, environmental innovation has a bilateral relationship with the level of proactive environmental management adopted by companies. Increasing of environmental innovation tends to come up against many barriers.

The Green Supply Chain Management (GSCM) is gaining prominence in the academy and business, as an approach that aims to promote economic and environmental gains. The GSCM is operated through the Environmental Management System Tools and treated as an Environmental Management System (EMS), involving Reverse Logistics, Green Purchasing, Green Sourcing, Green Design, Green Packaging, Green Operation, Green Manufacturing, Green Innovation and Customer Awareness. The objective of this study is to map the GSCM tools and identify their practice in a consumer goods industry in the Vale do Paraiba. The approach and data collection were made in the company's database chosen as the object of study, as well as through on site visits and interviews. The results showed that the tools Green Operation, Green Manufacturing, Green Innovation and Green Sourcing are applied in the company and just Costumer Awareness tool showed no practice at all. To other tools was identified ideology or interest of the company in applying them

This paper deals with the homologation process for obtaining carbon credits through the Clean Development Mechanism (CDM), that regulates the greenhouse gases reductions under the rules of the Kyoto Protocol. The CDM evaluates projects through a project cycle, which begins with the preparation of the Project Design Document (PDD) until the project certification to receive Certified Emission Reductions (CERs), popularly known as carbon credits. This study analyzed the implementation of the system Burner Recorder System for Low Flows of Biogas (QRBBV), developed by Marcelino Junior & Godoy (2009), in an eco-friendly wastewater treatment mini-plant (miniEETERA), built at the site of UNESP - Guaratinguetá SP. The QRBBV system is low cost and high reliability, developed to burn the methane generated at sites of low and variable production of biogas, which is not economically justified their energy recovery. Currently, almost all wastewater generated at the site of the campus is being treated by miniEETERA and, as a result, the biogas originated by this activity is being released into the atmosphere. Therefore, the project activity aims to capture and burn the biogas generated by miniEETERA, reducing the negative effects caused by the methane emissions into the atmosphere and, thus, claim to receive carbon credits. This work aimed to demonstrate the project applicability under CDM through the study and preparation of the PDD, as well as an analysis of the entire project cycle required for homologation. The result of the work obtained an estimate of only 20 CERs per year and proved to be economically unviable for approval through the CDM, since the spending with the approval process would not be compensated with the sale of CERs, mainly due the low carbon price in the world market. From an environmental standpoint, the project is perfectly... (Complete abstract click electronic access below)
