In this research, the practices adopted in two footwear industries, located in the southern region of Brazil, Vale do Sinos, to treat solid waste were investigated. Scientific literature, either national or international, converges on the perception of relevance of the environmental impact generated in this production chain, both due to the total volume of shoes that are manufactured and sold annually, and in view of the difficulties related to the disposal of footwear, at the end of its useful life. From this perspective, this study is justified and aims to identify and analyze, in the light of the reviewed scientific literature, which deals with waste from the footwear industry, the practices adopted in the treatment of solid waste in that economic sector. In order to achieve the objective, a case study strategy was carried out in two companies, using a qualitative approach, with the collection of empirical data through semi-structured interviews with organizational managers, indicated by the management of the organizations, in addition to documentary survey and participant observation systematic. The results showed that the two companies, one large and the second small, have a clear perception of the need to adopt sustainable practices and have already made several adjustments to the organizational system to promote alignment with sustainability principles. However, the actions and initiatives adopted to date show that the two organizations are still at an early stage of sustainability, especially in the solid waste treatment process.
本研究调查了位于巴西南部地区 Vale do Sinos 的两家制鞋业处理固体废物的做法。无论是国内还是国际科学文献，都一致认为，由于每年生产和销售的鞋类总量巨大，以及鞋类使用寿命结束后的处置困难，该生产链所产生的环境影响具有相关性。从这个角度看，本研究是合理的，其目的是根据所查阅的有关制鞋业废物的科学文献，确定和分析该经济部门在处理固体废物方面所采取的做法。为实现这一目标，在两家公司开展了案例研究，采用定性方法，通过对组织管理人员进行半结构化访谈收集经验数据，访谈由组织管理层指明，此外还进行了文件调查和参与式系统观测。结果表明，这两家公司，一家是大型公司，另一家是小型公司，都清楚地认识到采用可持续做法的必要性，并已对组织系统进行了若干调整，以促进与可持续原则保持一致。然而，迄今为止所采取的行动和举措表明，这两家公司在可持续发展方面仍处于初级阶段，特别是在固体废物处理过程中。

Forest conservation has transcended environmental concerns and become a determining factor in global social and economic issues. Therefore, setting forest conservation goals, including recovery and/or reforestation, is critical to help mitigate global warming and climate change. Although Amazonian countries have forestry policies for forest conservation, the forest continues to be degraded. The aim of this article is to suggest a regional governance model for the nine countries that share the Amazon rainforest. The thesis of the paper is that the definition of a common legal basis for the nine countries can contribute to forest conservation. Through qualitative analysis of exploratory and descriptive variables, the main topics related to the proposal of a governance model were identified. Multi-level governance contributes to the environmental conservation process by creating an environment to engage local, national, and international stakeholders from diverse groups. As a result of this paper, we suggest the creation of a supranational governance, composed and regulated by each of the nine countries of the Amazon biome and having as reference the AFR100 initiative. The proposition and creation of governance among Amazonian countries are fundamental for achieving the objectives for the conservation of the biome; such governance must take into account existing public policies, institutional mechanisms, and financial commitments. Although the Amazon countries present a framework of policies and commitments that seek to preserve the biome, the reality is that forest degradation through deforestation with negative effects on the climate and on the communities that depend on the standing forest still exists.

Globally, wetlands are ecological hot spots and as a result they supply a plethora provisioning, regulating, supporting and cultural services. Despite their functions, wetlands continue to degrade arising from urban developments (population growth and housing developments, road infrastructural developments, urban agricultures and usage of wetlands as dumpsites). These activities operate via land use/land cover changes at different scales in different areas depending on technology and needs of the population. This paper describes the implications of spatio-temporal land use/ land cover (LULC) dynamics in the Limbe I and III Municipality (L1&3Ms) and Douala IV Municipality (D4M) coastal areas from 1986 to 2022 on wetland ecosystem services. This research made use of Geographic Information System (GIS) technique in describing the land use/cover changes in the study areas. Primary data was obtained through field observations, questionnaires and ground truthing aim at confirming the observations on downloaded satellite imageries. Four Satellite images of different years (1986, 1999, 2013 and 2022) were downloaded from the United State Geologic Survey (USGS) Earth Explorer. Images were imported into Erdas Imagine, 2014 where preprocessing was done and Supervised Classification was adopted for the processing of the image to generate a raster format depicting the designed land cover/land uses; especially the wetlands which constituted one of the themes. Maps were generated to show changes in land use/cover which were transposed into tables and figures to show the trends in magnitude of changes, percentage of change and the rate of change. Within 36 years (1986-2022) built-up increased by 0.75km2 (0.36%) and 1.63km2 (0.45%) while wetlands retreated by -0.2km2 (-.96%) and -0.48km2 (-0.14%) in L1&3M and D4M respectively. Annually, wetlands decreased by - 97.04km2 and -191.54km2 while settlements/infrastructures increased by 294.33km2 and 644.46km2 over the same 36 year periods in L1&3Ms and D4M respectively. Base on wetland regulating services, changes in LULC has exposes neighbourhoods in L1&3Ms to flood vulnerability comprising the vulnerable, less vulnerable, least vulnerable and most vulnerable areas as opposed to two categories of neighbourhoods in D4M (most vulnerable neighbourhood’s and the less vulnerable neighbourhoods). Information on changes in land use-land cover is crucial in delineating impacted areas, understand the type of changes, their spatial patterns and the need for formulating proper urban planning and environmental preservation policies as well as updating these policies with time. GIS analysis of 1986, 1999, 2013, and 2022, indicated that, there have been significant modifications in observed LULC classes (forest cover, farmland and built-up land uses) over L1&3Ms and D4M.

The increase of the energy efficiency in buildings and greenhouses is important for reducing the use of fossil fuels and the emissions of greenhouse gases. Energy efficiency evaluation requires the consideration of both the embodied and the operational energy. Many estimations regarding the embodied and the operational energy in various types of buildings have been reported so far. However, studies regarding the embodied energy in agricultural greenhouses are rare while there are many estimations regarding their operational energy. The goal of our study is the comparison of the embodied and the operational energy in residential buildings and in agricultural greenhouses. The embodied and operational energies are compared in greenhouses as well as in low-energy and in conventional residential buildings. Our results indicate that the ratio of embodied energy to life-cycle energy in low-energy residential buildings and in nearly-zero energy buildings varies in the range at 36% to 83% that is significantly higher than the ratio in conventional residential buildings which is in the range of 6% to 20%. The ratio of embodied energy to life-cycle energy in agricultural greenhouses, at 0.86% - 70.41%, varies significantly depending on many parameters. The importance of carbon emissions related to embodied energy in low-energy buildings, in net-zero energy buildings and in agricultural greenhouses is highlighted. Our work could be useful to policy makers who are willing to accelerate the green transition to a low carbon economy in the coming decades.

Most research findings in Ghana and all over the globe lay much emphasis on the technical knowledge of plastics; especially giving preference to the biodegradable over the synthetic/Single-Use plastics. Questionnaires were administered to about 200 respondents in the Ho Municipality out of which 163 responses were filled and returned. Results showed that of all the variables tested only Legislative Framework has a meaningful impact on the behaviour of Ho indigenes. Awareness level: (Synthetic Plastics and Biodegradable Plastics) as well as Attitudinal Change do not influence people’s behaviour when using plastics. Findings from this study are further discussed and recommendations were proffered to instil eco-friendly behaviour among people.

The optimal tilt angle of photovoltaic panels plays a crucial role in energy generation. However, the accumulation of dust on solar panels can significantly impact their performance and efficiency, leading to a reduction in energy production. Therefore, it is crucial to consider the effect of dust deposition on the optimal tilt angle of solar panels. Regarding panel installation, it is often observed that panels are positioned to follow the natural slope of the roofs, disregarding the optimal angle for maximizing solar radiation utilization. Numerous studies have investigated the impact of dust accumulation on the performance of photovoltaic panels and the optimal inclination angle for different regions and seasons. This study aims to analyze the optimal tilt angle of photovoltaic panels for maximum energy generation, considering undesired effects such as dust, dirt, water droplets, and other atmospheric factors. The authors have proposed an equation to calculate the optimal tilt angle of photovoltaic panels based on a case study conducted in different Rio de Janeiro City regions. The methodology employed in this study involves estimating solar incidence on the surface of the photovoltaic panels using the authors' proposed equation, which considers the latitude and longitude of the panel installation location. The results obtained were validated using software that generates hourly solar radiation data. The results indicate that an inclination of 30 degrees, calculated using the proposed equation, resulted in a 2% deviation from the optimal theoretical angle.

The use of the microalgal biomass in biorefineries can produce different products, such as biofuel, food, feed, and bioactive compounds. In addition, the microalgae used in waste treatment can have its biomass exploited, such as Spirulina sp., which shows satisfactory results in the studies performed. Thus, the present study aimed to describe the production of Spirulina bioproducts in biorefineries, demonstrating its benefits and its potential for sustainable development. The study utilized an integrative literature review methodology, and the research question was "What bioproducts can be developed from a Spirulina biorefinery and how can they contribute to sustainability?". The articles were initially screened based on their title and abstract, and only those that fit the research question were selected for full reading. The reviewed studies suggest that the processing of microalgae within biorefineries has significant potential for synergy, sustainable processes can be developed that maximize the use of microalgae biomass and minimize waste and emissions. Spirulina can be used to treat wastewater from food processing plants, where microalgae could absorb nutrients and organic matter while producing biomass that could be harvested and converted into other bioproducts. However, challenges such as high operating costs, variability in biomass and effluent composition, and the need for scalable technologies must be addressed to fully realize the benefits of microalgae in biorefineries. Further research and investment in this area are necessary to develop cost-effective, scalable, and sustainable microalgae biorefineries, involving interdisciplinary collaborations between different fields and partnerships between academia, industry, and government.

The Environmental Product Declaration (EPD) is a type of label that has been considered reliable and complete, and it is commonly used in purchasing decisions, product design definition, environmental communication, data sources, and other applications. This article examines the approaches for the development of EPD in the Brazilian context, taking into account the initiatives of interested parties as well as the circumstances for its adoption by national firms. This work adds value by assessing which works in Brazilian literature and experiences focus on EPD, contextualizing the issue, and offering this type of label as a strategic resource. Between 2015 and 2022, the bibliographical survey uncovered 20 works. The Prisma 2020 checklist was utilized to conduct the systematic review, and the analysis in this study was both quantitative and qualitative. Since NBR ISO 14025 (2015), the publications have been consistent. Only 35% of the review content was obtained from journals, with 6 of the 7 publications resulting from academic works from their authors' postgraduate training processes, indicating a concentration of studies by a few scholars, all linked to universities in Brazil's south and southeast. Studies have shown that EPD is a valuable tool for environmental management due to its consistency, reliability, and completeness of data. However, due to a lack of Brazilian experience, this resource is not commonly known, disseminated, or employed. EPD has potential to be used as a strategic resource for businesses due to Brazil's normative, legal, and structural conditions for adoption.
环境产品声明(Environmental Product Declaration, EPD)是一种被认为是可靠和完整的标签，通常用于采购决策、产品设计定义、环境沟通、数据源和其他应用中。本文考察了在巴西背景下发展环境保护方案的方法，考虑到有关各方的倡议以及国家公司采用环境保护方案的情况。这项工作通过评估巴西文献和经验中哪些作品关注EPD，将问题置于背景中，并将这种类型的标签作为战略资源提供，从而增加了价值。在2015年至2022年期间，书目调查发现了20部作品。采用Prisma 2020检查表进行系统评价，本研究采用定量和定性分析相结合的方法。自NBR ISO 14025(2015)以来，出版物一直保持一致。只有35%的综述内容来自期刊，7篇出版物中有6篇来自其作者研究生培训过程中的学术著作，这表明少数学者的研究集中在巴西南部和东南部的大学。研究表明，EPD因其数据的一致性、可靠性和完整性而成为环境管理的重要工具。然而，由于巴西缺乏经验，这一资源不为人所知、传播或使用。由于巴西的规范、法律和结构条件，EPD有可能被用作企业的战略资源。

This work adds value by assessing which works in Brazilian literature and experiences focus on EPD, contextualizing the issue, and offering this type of label as a strategic resource. Between 2015 and 2022, the bibliographical survey uncovered 20 works. The Prisma 2020 checklist was utilized to conduct the systematic review, and the analysis in this study was both quantitative and qualitative. Since NBR ISO 14025 (2015), the publications have been consistent. Only 35% of the review content was obtained from journals, with 6 of the 7 publications resulting from academic works from their authors' postgraduate training processes, indicating a concentration of studies by a few scholars, all linked to universities in Brazil's south and southeast. Studies have shown that EPD is a valuable tool for environmental management due to its consistency, reliability, and completeness of data. However, due to a lack of Brazilian experience, this resource is not commonly known, disseminated, or employed. EPD has potential to be used as a strategic resource for businesses due to Brazil's normative, legal, and structural conditions for adoption.","PeriodicalId":408586,"journal":{"name":"Environmental Management and Sustainable Development","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128366135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

International cooperation in the field of seas and islands’ environmental protection is considered an inevitable choice in the current development trend. VietNam in recent years has constantly expanded cooperation with maritime countries in activities on integrated management of marine resources and environment. In order to meet the current cooperation needs, state management policies are also constantly changing to match the actual situation. Nowadays, the policies regulating international cooperation activities in our country's marine resources and environment are quite complete and systematic, perfect step by step. However, we need a lot of enthusiasm to be able to come up with optimal solutions because the implementation process is also facing many difficulties. This article aims to study the current status of international cooperation policies on marine environmental protection as well as the challenges in the practical implementation of this policy system.

Climate change involves a series of transformations in the synoptic systems of the planet. Its effects are not equitable, so the onus falls on the most vulnerable. Countries considered to be developing tend to be more vulnerable and therefore need to implement adaptation measures. However, these measures are not always viable within the social, environmental, institutional, geophysical, and economic dimensions, especially in the latter. Developing countries often need funding from international multilateral networks to make adaptation measures viable. Yet, projects that receive financing usually reproduce colonial aspects by erasing local knowledge, as in the case of measures implemented in São Tomé and Príncipe, and Bhutan. The essence of the ecology of knowledge concept can be a way for local knowledge to be valued and to be part of adaptation measures projects in countries considered to be developing.
