Keywords: Cleaner production, sustainable development, environment. Faccin UCS ; T. Abstract: The new economic context, based on fierce competition in the quest for market leadership, coupled with the rigid posture of customers, focused on the expectation to interact with organizations that are ethical, with good corporate image in the market and act in environmentally responsible, makes that companies seek to increase efficiency in the use of raw materials, water and energy through the non-generation, minimization or recycling of waste and emissions generated, bringing environmental benefits, occupational health and economic.
The methods used were the single case study and action research. We used several sources of data such as: documents, index, written reports and spreadsheets used by the company. This study aimed to contribute to the clarification of this issue, considered in the emerging globalized world. With the implementation of cleaner production methodology of the company significantly reduced the generation of waste and the costs associated with them.
It also reduced costs to the consumption of raw materials. With minimum investment return in that small space of time could accumulate economic and environmental benefits. Keywords: Cleaner Production. University of Cagliari - Italy.
Abstract: Urban population growth has triggered a process of change in rural areas and landscape patterns. This transformation has a twofold consequence. On one hand, land conversion causes loss of biodiversity and habitat destruction Deng et al. On the other hand, higher levels of food demand, together with the reduction of available land, endanger the capability of supplying food at local level.
The local food systems and food security is increasingly dependent by trade and transport costs. Local food system conservation is increasingly recognized as a key factor in the pursuit of sustainable and bio based economy perspective. Land food footprint is a significant tool in assessing food self-sufficiency, land displacement and thus food system sustainability. In this paper we analyse the evolution of land food footprint and landscape diversity in Sardinia over the period to assess the impact of land use change and food systems evolution. Time series show a decrease in landscape diversity and greater degrees of few landscape elements dominance, agricultural specialization and declining selfsufficiency.
In summary, these results show that diversified and traditional crops have been replaced by specialised, less labour-intensive crops and that the local food system is integrated by food imports, resulting in land unbalance land displacement , in landscape features simplification and in rural settlements abandon.

Abstract: Electricity cogeneration is growing worldwide based on the burning of fossil fuels — especially natural gas. Although its low emission factors, it is important to consider that the availability of natural resources must be taken into account for a long-term investment in the electricity generation sector. The identification of alternative renewable fuels and the integration of cogeneration to certain industrial processes that produce some of these alternative fuels are evaluated in this paper. Keywords: Cogeneration, alternative fuels, CO2 emissions minimization.
Abstract: The dyeing processes are extremely important for the differentiation and marketing of textile products. The dyeing takes place by fixing the dye molecule to the fibers, usually aqueous, that is, using water as the primary solvent for the process. It is estimated that spends on average liters of water per kilogram of textile article produced. Whereas there is currently great interest in finding environmentally sustainable substances for this process, one of the alternatives is the use of Ionic Liquid IL as solvent substance for dyeing textiles due to its low cost, simple synthesis, biodegradation of high character and abi lity reuse.
Until now, there has been few studies directed towards application LI for application to textile dyeing thus justified studies in this area. This study will present multi-fiber textile dyeing fabrics using Ionic Liquids base Diethanolamine DEA as a solvent instead of water. Abstract: The existence of an environmental sanitation system that meets the population for public water supply and sewage is so relevant for basic needs. This infrast ructure prevents water borne diseases and improves life's quality. However, the treatment process of water and out puts produces solid waste. The waste accumulated during the treatment process has as destination the aquatic system and soils of land near the stations.
This is deposited in nature form, without any pretreatment, which causes large environmental damage by insertion of chemical and biological contaminants in these environments, contained in the waste disposed. The adoption of alternative measures for proper disposal is an urgent issue. This approach brings work on reuse of material from the procedures operating of stations in some segments identified as units of utilization of these wastes. Every year it is generated around 1. Brazil produces 7. The appropriate USW management problem has showed to be a challenge, as factors such as quantity, volume, variety and complexity of waste entail risks for human health and the environment.
The indicators justify that the system is capable of performing gains in joules of energy J and emergy sej and presents great potential not only for waste treatment in Brazil, but also as a promising energy source, which is capable to assist on the energy demand by means of the exceeding production of 2. Universidad de La Costa - Colombia. Abstract: In order to assess the feasibility of a combined use of renewable energy sources over a determined region, it is necessary to carry out complementarity studies.
These studies let us know the generation profile of renewable energy sources, with high variability, over a specific interval of time and establish a possible match between two or more different energy sources. Such is the case of wind and solar energy sources. In this paper is presented an assessment study of the monthly complementarity of wind and solar resources over Colombia for electricity generation. It is proposed to assess the complementarity based on a novel approach, using a dataset obtained from high-resolution images of wind and solar monthly resource maps of Colombia; images previously treated using image processing techniques.
Then, the dataset is used to calculate average energy generation on each month of the year, and the complementarity of both renewable resources is obtained calculating the degree of correlation between them, with the Pearson correlation coefficient. The obtained results show a good degree of complementarity between both energy sources in some regions of Colombia, at the different seasons of the year. The results obtained in this study can be useful to identify regions with high potential of installation of power generation plants based on wind and solar energy.

Abstract: Cyanobacteria usually occurred in eutrophic waters, but the harvesting of microalgal biomass by flocculation was still facing a major technological and economic challenge. In order to solve this problem, the combination of microbial flocculant MBF and chitosan was used to flocculate the biomass of Microcystis aeruginosa.
In this way, all the algal cells aggregated together, and the algal flocs floated on the surface of solution and the algal flocs could be harvested by net 0. Zeta potential measurement confirmed the flocculation mechanism was charge neutralization. Microscopic observation revealed that some bubbles attached to the algal flocs which increased buoyancy of flocs. Some advantages above proved that combination of chitosan and MBF was a promising technology to harvest cyanobacteria.

Abstract: After the discoveries of the region known as "pre-salt" in , the Brazilian government haschanged some of the Brazilian laws with the aim of capturing the maximum of the rents arising from the exploration and production of hydrocarbons in this area. The topic discussed here is crucial for the country because the wealth coming from national oil reserves are finite. The oil and natural gas wealth can make a big difference in countries which use those natural resources wisely, for example, Norway has been seen as a good example of how an efficient and clear oil and natural wealth management can become sustainable over time.
In this sense, this article aims to analyze the institutional profile of the bordering counties in Sao Paulo state, one of the areas that possibly receive greater amount of income within Brazil in the coming years. The methodology is based on case study by qualitative analysis of development with a focus on socioeconomic profile and potential of the region studied.
As a result, the article points out that each beneficiary city should look its own public needs, calling its inhabitants to conduct educational and health programs that are important to that county in order to make the wealth derived from oil sustainable. Abstract: Faced with socio-environmental demands, economic growth marked by the socio-metabolic reproduction of capital is becoming increasingly exclusive and predatory.
The existing structure of production of goods and services no answers to the new reconfiguration experienced by the current market. The 21st century sees a repositioning of the production chain in the sense of mitigating the negative impacts on the environment. In this context, the identification of mechanisms that are targeted to the principles of circular economy is relevant to understand of development focused on the parsimonious use of natural resources and in the establishment of modus operandis that encourage the internalization of such precepts by the economy.
The purpose of this paper assumes the importance of the aforementioned sector as an example of organization aimed at implementing environmental efficiency, with the possibility of spreading these initiatives in other productive sectors among public and private enterprises. In fact, the reality is still well behind a process of internalization and radical change in the internal management of the public sector regarding the rational use of natural resources and the full implementation of circular economy.
Socio-environmental planning, be it voluntary or imposed Agenda 21, Public Administration Environmental Agenda, Sustainable Logistics Program and Eco Committee of Pernambuco , arises as a regulatory and supervisory instrument of good practices, to assist the process of public governance, to achieve success in the process of changing the inertia toward conscientious action, through socio-environmental responsibility. In this context, it is possible to observe that there are feasible public initiatives that endorse, in many aspects, the ramifications of circular economy.
Such initiatives denote the potential for replicability in other organizations under similar conditions. Abstract: With technological advances under way, the issue of pollutant emissions and reduced operating costs are important topics to be highlighted in any organization, highlighting the need to accept a different attitude that we use the resources we have available today. From a holistic view, This fact occurs due to financial, business, government, strategic reasons or simply for environmental awareness.
With the increase in mass of this problem, computers are part of a select group of pollutants, rated one of the major consumers of electricity, both in its production, and in your life, use and disposal on their behalf directly or indirectly, the increased emission of greenhouse gases that impact the environmental cond ition. This article is part of an abstraction on energy applied to Green IT, which is the sum of the energy management of the economy, with regard to resources.
Abstract: This article aims to describe as the application of the methodology of Cleaner Production CP interferes with externalities arising out of a process of production services.

Thus, when dealing with this process from the perspective of PML verified the existence of regressive and progressive positive externalities to adopt an electronic system of invoice payments. Abstract: The Brazilian law requires that the proper disposal of industrial solid waste is mandatory of the generator.
However, due to ignorance or lack of professionals in the environmental area on business, this issue becomes one of the main difficulties encountered in order that the manufacturing process generates, in most cases, waste and environmental impacts, which do not receive the due attention. In other hand, this waste can be utilized as an alternative source to increase eco-efficiency and as a larger object to eco-effectiveness, reducing the impacts, increasing the economic and environmental efficiency and contributing to sustainability. The metal-mechanical sector also faces the problem of environmental management, need urgently adapt to the production process, innovative technologies to act in order to achieve sustainability.
Thus, the aim of this study is to evaluate the ecoefficiency and eco-effectiveness of the methods used in the cleaning of metallic chips contaminated with cutting fluid metallurgical enterprises. This review was performed by criteria identified in the literature, to which you can evaluate methods as eco-efficient and eco-effective. In practice found only eco-efficient methods, and among them, some with eco-effective practices. The results show that the culture of repair, reuse, recycle and intended instead to promote actions such as the remodeling of a production system in a closed cycle where no waste generation is now even more practical and realistic.
Nonetheless, it is clear that eco-efficient and eco-effective principles improve the environmental performance of companies, reducing expenses related costs for inputs, raw materials and disposal of waste, and contribute to achieve higher levels of sustainability. Brauer FSP , I. Barbosa UFSCar.

Abstract: The accelerated development of constructions of buildings in large cities brings degrading impacts on the environment and people's lives. One can consider another point of observation concerns not only the volume of inputs used, but the strong consumption of resources like water, electricity, discomfort in the vicinity of the project, ventilation.
Society as agent of change has required the use of these resources better entrepreneurs associated with the economy, reduction and even total replacement forcing streamlined and sustainable innovation. In order to improve the quality of the built environment and minimize its negative impact on the natural environment, various methods for measuring sustainability is being developed by different countries and regions. The study aims to analyze the methodology High Environmental Quality HEQ of international review and adapted to Brazil by Vanzolini, its criteria, definition of parameters for the management and monitoring, structure and applicability.
It is discussing its convergence with the dimensions of sustainability: social, cultural, environmental and economic criteria and the certification and maintenance of the title. As a result it was possible to verify which requirements are suitable for the methodology of sustainability certification, policies and proposed criteria, management and future studies. Abstract: In each product production process, the incorporation of techniques and methods to reduce waste and environmental issues are generally facilitating the maintenance of a natural more balanced.
The clean production is a good alternative for this to occur. Considering the whole production cycle and incorporating environmentally sustainable techniques, the life cycle of industrialized something is optimized, which prevents techniques pipe end. The bamboo plant easy to grow and good workability, has been applied in various purposes such as the production of flooring, furniture, fixtures and even decorative structures in civil construction and cement.
This plant to be inserted in the manufacture of laminated bamboo plates avoids, for example, species of wood endangered may be used. When used, this plant is from crops specifically grown for various purposes which may have bamboo and features. This work has as main goal to evaluate the efficiency of different adhesives used for making laminated bamboo panels. In forming laminated boards, the process can be summarized in the defoliation of the plant and general cleaning for the removal of unwanted parts, cutting planer four sides for finishing cutting, gluing of parts and finally finishing determine where this material may be applied.
This technical-scientific research laboratory tests were performed, where properties of twelve laminated bamboo beams can be compared. The plant was chosen type Dendrocalamus giganteus. This genus is one of the best to perform carpentry work. For each type of adhesive applied to the plates of laminated bamboo, bending tests reduced size , hardness, density, screw with drawal, shear stress and shear stress at the glue line, a tool constituted conclusive on the workability of the different Products promoters junction between the parts that form the plywood. In some types of adherent reviews have not responded well to tests, bringing the disruption of certain body-of-evidence, but one can prove the efficiency of adhesives used in the manufacture of laminated bamboo.
The technology of bamboo utilization for the formation of products useful in our daily lives is something shown by research centers of renowned educational institutions, and this work is the result of a detailed study on the plates made with bamboo. In environments with significant levels of humidity and temperatures can shorten the use of furniture, laminate made with Dendrocalamus giganteus has higher efficiency over other matters falling in the furniture industry.

Abstract: Municipal solid waste witnessed an exponential increase globally due to plastic, paper and organic material high production without considering appropriate recycling strategies. Pyrolysis and gasification is considered the most promising chemical recycling techniques, which can help prevent incineration and landfilling.
Both processes have low environmental impacts, high product value, ability of electricity generation illustrated in this work. The paper discusses the major process units in industrial chemical recycling plants, life cycle assessment LCA in terms of GHG emissions, process stages and system design and justifies gasification and pyrolysis over other thermal treatment methods.
Pyrolysis and gasification produce hydrocarbon gaseous and liquid products which can be utilized for energy production or chemicals synthesis while only incineration produce thermal energy. Both processes also produce the highest electrical production per ton in comparison with incineration with higher carbon dioxide emissions than incineration but lower dioxins, NOx, HCl, CO emissions.

Abstract: To remain competitive, organizations establish integrations with their partners, customers and suppliers through a supply chain. This integration occurs through the sharing of resources and information, in a cohesive and high performance business model, in order to meet the needs of consumers. One of the competitive strategies adopted in the supply chain management SCM context is the green supply chain management GSCM approach.
This approach, like SCM, helps organizations and their partners achieve corporate profit and market share goals, but incorporates environmental aspects related to operational activities that occur along the chain, since environmental concerns have been a frequent theme in the business world. Regarding the packaging, the return activities correspond to the reverse logistics of post-consumption, and refer to those products that have reached the end of their useful life.
However, when it comes to cardboard packs, these are commonly reused, since they have favorable characteristics for such accomplishment, such as: high strength, easy handling and low cost. Thus, it is considered that the shelf life of the cardboard is not limited to the final consumer and therefore the chain to which this product belongs is not restricted to this agent either, as SCM scope analyzes are generally conducted.
In this sense, starting from the retail perspective, as the corporate agent closest to the consumer, this study aims to analyze the structure of the cardboard chain, given from the discarding of retail, from the perspective of the GSCM. Therefore, the methodology adopted is a qualitative approach, of a descriptive and exploratory nature. The data were collected through bibliographic research and the conduction of semi-structured interviews with the organizations belonging to the cardboard chain.
The information obtained allowed the elaboration of a mapping, in which it was possible to identify that, after being discarded by the retail sector, the cardboard is directed to three different paths, being two chains of consumption and one of discarding. In addition, after this identification, we conducted analyzes of each destination of the cardboard by the environmental perspective given by the approach of the GSCM.
As a result of this analysis, it was identified that the most appropriate way that cardboard can take after its disposal is to follow a recycling chain, which will allow the reduction of environmental impacts regarding the extraction of natural raw materials, as well as the economy of resources such as water and energy. Abstract: Daily debates are held regarding the environment, resource rationalization and green building, and Brazil follows the worldwide trend of technological development in search of products that follow the sustainable line.
Faced with this problem, which is not limited to this country, Green Buildings represent a significant contribution to reducing the consumption of natural resources, both in the construction and operation of buildings maintenance. Within this framework, environmental certification is an important instrument that has great potential to implement better sustainability practices in the sector. Case Study: Ingenio Risaralda S. Ingenio Risaralda S. This productive sector was industrialized with its core business the specialization in the process of sugar production and then expanding its industrial activity to the production of biofuels ethanol fuel and to the generation of electricity.
The main objectives for the sustainability of the sector are to seek the reduction of fossil fuel use in the world and the reduction of greenhouse gas emissions. Among these stages, the Life Cycle Inventory LCI phase was the most demanding, because it is the field data collection phase and its subsequent structuring for the LCA. For the environmental impact analysis, the project focused on the ReCiPe Midpoint H method, which evaluates 18 impact categories.
The system studied includes the bioethanol supply chain at the Ingenio Risaralda S. It was found that the field phase is responsible for 4 of the 18 impact categories; that harvest phase contributes to 5 of the 18; the factory phase is responsible for 7 of the 18; the distillery phase contributes to 2 of the 18, and the cogeneration phase implies a positive environmental impact in the climate change category, since it uses the energy in the form of heat produced by the bagasse to generate steam and then through the use of turbogenerators to electric energy.

Abstract: The gemstone productive chain and jewelry is an important income source and job generator in Brazil, since the country stands out worldwide for the extraction and processing of these materials. However, this activity generates a high volume of waste.
In this way, this work aims at analyzing the generation of waste in a gemstone processing industry and at proposing alternatives for its treatment and reuse in other applications, like, for example, in the composition of ceramic clay. This is a quantitative approach research of descriptive and exploratory character, and there were used bibliographies and case study.

Abstract: The concept of Cleaner Production advocates the continuous application of preventive and integrated environmental strategies to processes, products and services, incorporating the most efficient use of natural resources and minimizing the generation of waste and pollution, as well as the risks To human health.
But not always technological innovations in production bring with it an improvement for Cleaner Production. Works pointed to a concentration of the residues of the productive process in the manufacturers due to the verticalization of the production stages. But from the incorporation of the technology of machining of the blocks of polyurethane through Computerized Numerical Control CNC there was a horizontalizacion of the process. The introduction of the technology provoked the emergence of companies that started to incorporate the productive sector.
From this structural change of the industry came the questioning of which actors produce waste and how they manage it. The objective of this work was to map the current process, identifying the residues in the actors inserted in the productive chain detailing how these wastes are managed. A case study was carried out where the object analysis was carried out through the application of a field study where a mapping addressed the qualitative and quantitative issues of the production of surfboards.
The data collection was done through a visit to the pre-selected targets through the application of Cleaner Production forms. Throughout the research it was evident that the links of the production chain can be executed by different actors participating in the industry, with a decoupling of the links from the manufacturers, mainly related to the volume of production. That is, the largest concentration of outsourcing of steps occurs in the smaller manufacturers with a shift in the volume of materials and waste for large distributors, large manufacturers and rolling mills.
It was clear that the introduction of CNC technology was responsible for the decentralization of waste, previously focused only on manufacturers, but that technological innovation had no impact on waste reduction or reuse, or even better disposal management.
