“…Polymer composites based on thermoset resins [51]- [54], foams [55], rubbers [56] and thermoplastic ones such as PE [45], LDPE [57], HDPE [58], PU [59], PLA [60], PP [61] [62], and PVC [63]. Many industries apply natural fiber composite materials in their manufacturing processes, civil engineering [64], construction [65], automotive [66], military [67], aerospace, marine, clothing [68], among others [69], [70]. The main reasons for using the SB as reinforcement in polymer composites are the reduction of environmental impact and import expenses of some products for agricultural production.…”

Even some natural resources, considered as waste, can be used for manufacturing a lot of products with enhanced sustainable properties, such as cellulosic bagasse. In this review was performed in order to gather state of the art about natural fibers structure, properties, and applications in polymer composites reinforcement, giving an approach of bagasse sugarcane fibers. The literature was done in different scientific databases;more than 50 papers wereanalyzed. The vegetable fibersare an extensive and multipurpose group, bagasse sugarcane fibers emerge as a remarkable renewable resource, due to their suitable properties and a large amount of available resources worldwide. Nevertheless, this kind of products require the use of adequacy physical and chemical treatments in order to achieve an adequate proper interaction with polymer matrices, additionally, other characteristics as the geometry and fiber content can influence the performance as reinforcements in composite materials.

“…The growing commercialization of flex-fuel vehicles, which can operate with any proportion ratio of ethanol and gasoline [2], combined with the favorable climate for the cultivation of sugar cane, the main source of the biofuel extraction in the country, and the mandatory 27% blend in gasoline are the major reasons for the ethanol success in Brazil [3][4][5]. Besides, the country's already existing experience with the fuel production and distribution is notable, once the Brazilian sugar ethanol industry dates back to 1970 due to the pro-alcohol initiative, which was an ethanol incentive program in the market that emerged after the 1970s oil crisis [1,6].…”

The growing commercialization of flex-fuel vehicles in Brazil demands the optimization of internal combustion engines for the operation with ethanol (E100) and gasohol (E22), in an attempt to reduce the fuel consumption and minimize the pollutant emissions into the atmosphere. In this sense, this work proposes the study of different volumetric compression ratios in a single-cylinder research engine in order to conclude about its fuel conversion efficiency and, in particular, a more detailed combustion investigation for two of the most common Brazilian fuels. Dynamometric bench tests were performed for distinct compression ratios, injection systems and fuel types, which demanded a specific piston design to meet the requirements for each combustion chamber configuration. The use of ethanol was the most suitable when compared to gasohol, especially at high load conditions, in which was observed a knock tendency for E22 but not for E100, due to its improved physicochemical properties, resulting in enhanced combustion aspects. The proposed methodology proved effective in allowing fuel conversion efficiency gains for the tested fuels, injection systems and piston designs when compared to the engine baseline operation, with up to 6.1% improvement when using the most appropriate compression ratio. Finally, the ethanol direct injection confirmed the potential of this Brazilian biofuel as one of the most promising renewable options for internal combustion engines in current and future sustainable energy directives.

“…Recent studies have confirmed that codes of conduct based on external standards have positive impacts on social and environmental performance [25][26][27][28]. However, some studies address signaling effects as the main motive for the establishment of codes of conduct [19,29,30]. According to Kutting [20], the establishment of codes of conduct is at least an admission that these activities need to be regulated.…”

The Factors Affecting the Environmental Practices of Companies: The Case of Serbia

Environmental practices are often considered external to the business, and the impacts of self-regulation and other CSR company practices on environmental practices are important but not fully understood-especially in transitional and developing countries. The aim of this paper is to explore factors that influence the environmental practices of companies operating in Serbia. We observed four types of self-regulations (core values, codes of conduct, ISO 9001, and ISO 14001); the level of CSR practices in relationships with employees, customers, the local community, and society, and related to business transparency; as well as company features related to types of operations (manufacturing vs. service), size, and internationalization (multinational ownership and export activities). Based on the SEM analysis of data collected from 178 companies operating in Serbia, the findings showed that smaller, manufacturing companies that applied the observed types of self-regulations, which have a higher level of employee relations and are more social and community involved, are more likely to have higher levels of environmental practice. Among the observed self-regulation types, only ISO 14001 certification proved to have an individual effect on company environmental practices. However, our results also showed that the influence of core values, applied codes of conduct, and ISO 9001 certification cannot be neglected.Sustainability 2019, 11, 5960 2 of 17 the decoupling phenomenon, the discrepancy between policies and practice, or the formal adoption of self-regulation by a company that does not become incorporated into the day-to-day routine [16] has its roots in the company's intention to communicate more than achieve [11]. The public disclosure of self-regulations related to environmental activities in order to present a proactive environmental image by providing greenwashing [3] raises concerns related to the effectiveness of such self-regulations.
