Dairy cattle farming is an activity of great economic importance in Brazil; however, this activity presents high water consumption and volume of waste generated. The objective in the present work was to measure water consumption and waste generation during mechanical milking, in order to promote rational initiatives for the process. The farm property showed the consumption of 64.76% of the whole used water per day and generation of 35.24% of waste-water in the milking process. After orientation, the average coefficient of water consumption in the cattle sector decreased to 3.2 liters with a daily production of approximately 550 liters of milk and an average water consumption of 1,764.83 liters per day. The implementation of equipment and adoption of mitigation measures was associated with a significant reduction in water waste.

The energy transition can be defined as all the transformations of the system of production, distribution and consumption of energy carried out in a territory in order to make it more ecological. The aim is to reduce the environmental impact of an energy system. Inseparable from sustainable development, the energy transition contributes to the fight against global warming, through the implementation of changes based on innovative technologies, but also and above all on new political orientations. The paper focuses in particular on city logistics in Europe as an illustration of energy transition, showing that strategic interactions between city logistics stakeholders are at the heart of new practices, particularly in the implementation of low emission zones (LEZs). A case study was conducted with a large French metropolitan area, which is at the forefront of sustainable city logistics. This case study is based on an analysis of official documents written as part of the implementation of the LEZ. Using a conceptual framework drawn from the SCP paradigm, which is at the origin of the industrial organization’s stream, the results indicate that the success of environmental city logistics strategies depends effectively on interactions between several public and private stakeholders, and not only on virtuous managerial practices from companies.

This study discusses and analyzes an alternative of IOT reuse as addition in structural mortars, evaluating the influence of IOT addition contents. The material was physically and chemically characterized. Structural mortars were molded with 10%, 20%, 30% and 40% of addition of IOT in relation to cement mass. We investigate physical properties, mechanical indicators, durability indicators and microstructure. The tailings are composed of predominantly quartz, hematite and goethite, and no components were found that could compromise the cementitious composites. The addition of IOT provided a tendency to reduce open porosity. The addition of 30% IOT was the most efficient in closing pores. All addition contents led to the maintenance or gains in mechanical properties, and a 10% gain in flexural tensile strength was observed for the addition of 10% IOT. The addition of 40% IOT promoted a 14% gain in compressive strength and maintenance of flexural tensile strength. This addition content evidences that the carbonation depth was not significantly affected. Based on the results, the addition percentages of 30-40% are interesting as to the analyzed properties.

Scientific production on Triple Bottom Line Theory is, recently, attracting attention in the literature. A series of factors are related to this interest, among them: (i) the scarcity of productive resources; and, (ii) the need to optimize processes not only in economic terms, but especially in their environmental and social aspects. These factors have fostered the study of sustainability models. Therefore, the present study aims to conduct a bibliometric investigation into Triple Bottom Line Theory. To this end, an analysis of 1386 publications, published between 1999 and 2020, indexed in the Web of Science database, was developed. Additionally, the present article describes in detail the main contributors to the academic debate on this topic. Furthermore, it highlights the relevant areas of research at the present time. It was found that the search for models to assess environmental, economic and social performance is highly relevant today. It was also found that, among the main models used for this purpose, the class of Data Envelopment Analysis models stands out.

Sustainable development in the 21st century depends on the reuse of materials and products, as well as on economic and environmental incentives for recycling. Several studies have sought to improve the quality of concrete, as well as its durability and strength, by adding fibers (metallic, polypropylene, carbon, vegetables) or by replacing the aggregate. The use of optical fiber waste in concrete is still incipient and few studies address the use of marble aggregate to be used in concrete. This research assesses the behavior of the mixture composed of: Portland cement + fine aggregate (sand from crushed marble waste) + coarse aggregate (gneiss) + optical fiber waste and water. The compressive strength, the tensile strength and the modulus of elasticity of concrete and the durability of optical fiber waste in alkaline composite were tested through microstructural evaluation. The results present an increase of about 20% in the mechanical properties and a reduction in the rigidity of the mixture, making the material more ductile. The superficial protection of the fibers made them more resistant to the alkaline attack of the cement. The knowledge acquired would allow the creation of sustainable concrete reinforced with optical fiber in a much more efficient way.

The reuse of residue is an alternative that benefits the industries, adding value to the residue and still reducing the costs necessary with the treatment before its disposal, but it can also enrich human food. The malted barley residue (malt bagasse) is the main residue obtained in the manufacture of beer. However, it is often discarded in the environment incorrectly or used as feed. Its nutritional potential, its ease of obtaining and its low cost, are incentives for this ingredient to be used in food. The present study is aimed at carrying out the physical-chemical characterization of the malted barley residue, in order to assess its nutritional potential. Physical-chemical analysis showed that the bran from malted barley residue presented high content of fibre, proteins and minerals, mainly phosphorus, in addition to a significant amount of potassium, iron and calcium and low sodium content. Thus, the malted barley residue showed nutritional potential to be used as ingredient in food formulation, being a sustainable way of the food industry to take advantage of this residue. The malted barley residue can be an important ingredient in the production of breads, cakes and cookies, among other preparations. These would be low-cost foods, representing savings both for the beer sector, which needs to dispose off the residue, and for the food industry, in addition to contributing to the preservation of the environment. Thus, the present study shows that the reuse of malted barley residue is a sustainable practice with environmental, economic and nutritional importance.

This study aimed to identify the level of services provided by the business incubators and their impact on business success. The sample for the field study consisted of 30 businesses that benefited from business incubator services at Jordan Enterprise Development Corporation (JEDICO). Various techniques, such as descriptive and analytical methods, were utilized in the study to test the hypotheses. The results demonstrated that beneficiaries perceived business incubators’ support practices as high level and that there was a statistically significant impact of business incubators on business success where the networking support services dimension had the highest influence on business success, followed by infrastructure support services. As a result of the findings, the study has provided a set of recommendations.

Composting is a sustainable alternative regarding an environmentally appropriate management of the organic fraction contained in the municipal solid wastes. To minimize nitrogen losses during the biostabilization process, due to ammonia volatilization, the present study aimed to evaluate the composting technique combined with the possible precipitation of struvite (MgNH4PO4.6H2O). A mixture containing food wastes was subjected to different experimental composting conditions with synthetic chemicals of magnesium and phosphorus—0.020 mol kg-1 (EXPI) and 1.8 mol kg-1 (EXPII), in addition to the control treatment (CONT). Experiments were carried out in closed systems, under forced aeration, over a period time of 56 days. In general, the addition of synthetic chemicals provided a nutritional increase in the organic composts obtained at the end of the experimental period in both conditions (EXPI and EXPII) compared to the treatment CONT. It was observed a total nitrogen conservation of about 21% and 122% in samples of composts obtained under the conditions EXPI and EXPII, respectively. Germination tests of lettuce seeds (Lactuca sativa) were also carried out to evaluate the agricultural applicability of the composts obtained in comparison with a commercial substrate (COM). A germination index with an average value of 87% was reached with the use of 100% of the compost obtained under the condition of greater conservation of total nitrogen (EXPII). Finally, the strategy considered for the conservation of nutrients in organic composts showed technical feasibility, indicating the formation of struvite and/or its analogues in the products obtained.

Due to a global environmental issue where plastic waste gets into our water resources, this research identified management perspectives on the implications of moving to plastic-free beverage services at sport facilities. The focus encompassed implications of both eliminating plastics and the introduction of biodegradable alternatives. Semi-structured interviews were conducted with a purposeful sampling of expert food and beverage managers employed at sport facilities with Canadian Hockey League tenants. Interview questions were developed using Transition Management Theory (Kemp, Parto & Gibson, 2015), Attitude-Behaviour-Gap (Jacobs et al., 2018), concepts of consumerism (Koskijoki, 1997), and the call for sustainability business models (Borgert et al., 2018). Using thematic analysis, this study accessed the nuanced understandings of plastics use and the implications of implementing biodegradable alternatives. Results revealed inconsistent environmental management strategies: that government mandates are key; that there is a lack of public pressure concerning plastic waste management pratices; that bioplastic options are overlooked; that seven barriers impact the use of plastic alternatives; and, that mitigation and management of plastic is not their management role. In conclusion, much work is needed to move towards eliminating plastics and the introduction of biodegradable alternatives at sport facility concessions.
