Retail growth is a result of the diversification of departments with the intention to look to consumer’s needs and level of demand. Pressed by consumers and by the law, the adoption of environmental preservation practices is becoming stronger among grocery retailers. The objective of this research was to analyse the practices of reverse logistics performed by a retailer and measure the amount of waste generated by each department. To reach the proposed goal, a field research study was conducted to directly observe a grocery retailer in the state of Sao Paulo, Brazil, for a period of 6 months and monitor the amounts of cardboard and plastic discarded by each department. Using the Wuppertal method, the first result observed was that the retailer stopped its monthly production of approximately 20 tonne of biotic and abiotic material, which influence global warming and degradation of the ozone layer. Another result observed with the implementation of reverse logistics, was that the general grocery department mostly used cardboard and plastic. This sector includes products such as food cupboard, drinks, household, health and beauty, and pet articles. The fresh fruit and vegetable department and the meat, chicken and frozen department were increasingly using less plastic and cardboard packaging, increasing the use of returnable and durable packaging and thus promoting sustainability.

Aims: The aim of this study was to investigate the influence of the perception of greenwashing in the beliefs, attitudes and the perceived benefits by consumers to green products at retail facing the social control exerted by advertising. Study Design: For the verification of the proposed objective, an exploratory research was conducted within a quantitative nature through a survey. Place and Duration of Study: State of Sao Paulo, Brazil, between November 2015 and February 2016. Methodology: The study had a sample of 359 valid respondents of the State of São Paulo / SP. The sample is composed of 73% women and 27% men, whose family allowance was $ 1,250 (26.6%) and US$ 625-940 (24.7%), and 75% of these consumers go to the supermarket at least once a week. For the data analysis, the Structural Equation Modeling (SEM) was applied through the software SMARTPLS 2.0-M3. Results: It was observed that the greenwashing tends to cause confusion in the perception of green consumption, and when the consumer perceives the existence of greenwashing, it reacts negatively in relation to the beliefs, attitudes and perceived benefits for green products, and no longer believes in the product and in the credibility of the company. Conclusion: One of the problems arising from the greenwashing is the impact on the companies that operate ethically in the market. For the consumers, it is difficult to identify the difference between products that answer the needs of environmental sustainability. And despite the strong pressure from the media and advertising, when the consumer realizes that in the product there are characteristics of greenwashing, it rejects the product or the brand that calls itself green and is not.

In the face of new market opportunities, farmers can increase the value of the product. This is in Short Food Supply Chains (SFSCs) based on the value of origin and tradition. Farmers use this valuation as a product differentiation that improves their economic Sustainability. Therefore, this work aims to analyze the economic Sustainability of specialty coffee farmers in Garça, Sao Paulo State (Brazil), after participating in SFSCs. For this reason, the research approach was qualitative and quantitative, with the study of several cases and the application of the semi-structured form with farmers. Data analysis, descriptive statistics, and Wilcoxon Rank-Sum Test were used. The results indicated the introduction of farmers in new markets, various distribution forms, and the addition of product varieties and premium prices, which contributed to profitability. Infrastructure costs, however, were expensive. One of thecontributions of this study is to describe the specialty coffee supply chain when it is sold directly for consumption, shifting from the traditional coffee market to short chains, contributing to the literature, and the farmers in a country with limited financial resources addressing an improvement of income. Key words: Direct sales; Alternative food networks; Territory; Direct farm marketing; Economic local.

A discussão sobre o consumo verde e, consequentemente sobre os produtos verdes oferecidos no varejo atrai a atenção do consumidor quanto ao seu estilo de consumo. Contudo, é importante saber se o consumidor está ou não indiferente (cético) ao tema em questão. Sendo assim, a presente pesquisa busca saber: Será que o ceticismo produz efeito mediador entre a intenção de compra e a compra declarada para produtos verdes no varejo? Assim, o objetivo do presente estudo foi analisar a influência do ceticismo como mediador para o consumo de produtos verdes no varejo observando como o consumidor percebe esta questão na sociedade. Para resolver esta questão e atender ao objetivo proposto, foi realizada uma pesquisa de natureza quantitativa por meio de um survey junto a uma amostra de 1028 consumidores reais coletados em três capitais brasileiras, Brasilia/DF, Salvador/BA e Belo Horizonte/MG. A análise de dados foi feita utilizando a modelagem de equações estruturais por meio do software SmartPLS 2.0 M3. O resultado indica que o ceticismo não possui efeito mediador para a relação entre intenção de compra e compra declara, mas, por outro lado e comparado a outras pesquisas, a relação entre intenção de compra e compra declarada vem aumentando ao longo do tempo em termos de carga fatorial e isso pode significar que o consumidor está se mostrando mais atento as questões ligadas ao consumo de produtos verdes no varejo.

Paper aims The objective of this paper is to evaluate the economic, social, and environmental impacts of logistics activities of a dairy producer located in Brazil. Originality The main contribution is to apply a quantitative approach to assessing sustainable logistics in the milk supply chain, serving as a basis for future work on this theme. Research method A single case study of a regional producer of dairy products in Brazil is carried out in this research. A sustainable logistics evaluation model was used that quantitatively measures the impact of transportation, storage (including inventory management and material handling activities), packaging, and acquisition activities in the economic, environmental, and social dimensions. Main findings It illustrates the challenge that a Small Medium Enterprise (SME) will have to expand its logistics actions, aiming to generate benefit to the consumer because of actions in the economic, environmental, and social dimensions. Implications for theory and practice This research expands the literature, as it brings together topics such as sustainability, logistics, supply chain, and agribusiness. The baseline is in the case study with quantitative data that allows us to answer the question of how to be sustainable now, rather than waiting for supply chains to do it first so we can discover it.

Purpose: This study aims to present consolidated information on blockchain, which seeks to better clarify the concept of blockchain and the associated implications and characteristics.Design/methodology/approach: The methodological procedure used was Grounded Theory, based on a Systematic Bibliographic Review on the adoption of blockchain in supply chain management. To add experts' opinion on the subject to the analyzed panorama, data from a survey were also considered in the analysis.Findings: The Grounded Theory enabled the development of consolidated information on blockchain related knowledge, identifying benefits, fragilities and contributions of the concept for supply chain management.Originality/value: An epistemological gap has been identified between the use of blockchain in supply chain management and a theoretical basis to support the application. The originality of this study lies in providing a proposition of this theoretical basis.
