DPTV-based analysis of the flow-structure/wall-shear interplay in open wet clutches
Authors: Leister Robin , Kriegseis Jochen
Published: September 2021

The trend to lower energy consumption in the automotive industry still offers potential in various fields of application. One powerful saving strategy is described by the idling behavior of wet clutches, where the speed difference between drive and output, and the cooling oil in combination with a sub-millimeter spacing leads to significant amounts of wall shear stress (WSS) and accordingly drag torque. Minimization of this adverse effect has been found to be possible by means of grooved clutch-disk geometries, which have been demonstrated to correlate with the drag torque (see e.g. Neupert et al., 2018). The main interplay between torque and fluid flow in open wet clutches has been analyzed by Leister et al. (2020) in a dimensionless way. Today, a detailed investigation of a clutch flow, however, is missing for a larger variety of groove patterns and the cause-effect relations remain yet to be fully understood. Especially, the clear identification of the so-called foot print of a particular groove geometry in the flow field and corresponding WSS – thus drag-torque predictions – still requires further research efforts.
Particle Image Velocimetry Measurements of a Dry Powder Inhaler Flow

Published: September 2021

Inhalation therapy for respiratory disorders is being increasingly delivered via dry powder inhalers (DPIs), which are breath-actuated devices that deliver pharmaceutical drug particles to the lungs. The motion of inhalation air, produced when a patient inhales through this device, supplies all energy for the entrainment, de-agglomeration, and dispersion of powder drug agglomerates into a fine drug particle aerosol. The aerosol performance is directly related to the fluid-mechanics of a given DPI device. These flow mechanisms are complex as they depend on the device design, inhalation flow rate, and the properties of the dry powder formulation used. Among these, the role of device design is crucial as it significantly affects not only the generation and properties of delivered aerosol, but also the capability of targeted regional drug deposition.

Published: September 2021

Exhalation of small aerosol droplets and their transport, dispersion and (local) accumulation in closed rooms have been identified as the main pathway for indirect or airborne respiratory virus transmission from person to person, e.g. for SARS-CoV 2 or measles (Morawska and Cao 2020). Understanding airborne transport mechanisms of viruses via small bio-aerosol particles inside closed populated rooms is an important key factor for optimizing various mitigation strategies (Morawska et al. 2020), which can play an important role for damping the infection dynamics of any future and the ongoing present pandemic scenario, which unfortunately, is still threatening due to the spreading of several SARS-CoV2 variants of concern, e.g. delta (Kupferschmidt and Wadman 2021). Therefore, a large-scale 3D Lagrangian Particle Tracking experiment using up to 3 million long lived and nearly neutrally buoyant helium-filled soap bubbles (HFSB) with a mean diameter of ~ 370 µm as passive tracers in a 12 m³ generic test room has been performed, which allows to fully resolve the Lagrangian transport properties and flow field inside the whole room around a cyclically breathing thermal manikin (Lange et al. 2012) with and without mouth-nose-masks and shields applied. Six high-resolution CMOS streaming cameras, a large array of powerful pulsed LEDs have been used and the Shake-The-Box (STB) (Schanz et al. 2016) Lagrangian particle tracking algorithm has been applied in this experimental study of internal flows in order to gain insight into the complex transient and turbulent aerosol particle transport and dispersion processes around seated breathing persons.
Measurement of the acoustic streaming pattern in a standing surface acoustic wave field
Authors: Sachs Sebastian , Cierpka Christian , König Jörg
Published: September 2021

The application of standing surface acoustic waves (sSAW) has enabled the development of many flexible and easily scalable concepts for the fractionation of particle solutions in the field of microfluidic lab-ona-chip devices. In this context, the acoustic radiation force (ARF) is often employed for the targeted manipulation of particle trajectories, whereas acoustically induced flows complicate efficient fractionation in many systems [Sehgal and Kirby (2017)]. Therefore, a characterization of the superimposed fluid motion is essential for the design of such devices. The present work focuses on a structural analysis of the acousticallyexcited flow, both in the center and in the outer regions of the standing wave field. For this, experimental flow measurements were conducted using astigmatism particle tracking velocimetry (APTV) [Cierpka et al. (2010)]. Through multiple approaches, we address the specific challenges for reliable velocity measurements in sSAW due to limited optical access, the influence of the ARF on particle motion, and regions of particle depletion caused by multiple pressure nodes along the channel width and height. Variations in frequency, channel geometry, and electrical power allow for conclusions to be drawn on the formation of a complex, three-dimensional vortex structure at the beginning and end of the sSAW.
Experimental Study to Quantify the Rotor-to-Rotor Interaction Characteristics of a Small Unmanned-Aerial-Vehicle
Authors: Zhou Wenwu , Ning Zhe , Hu Hui
Published: September 2021

The flow interactions between laterally aligned rotors were investigated experimentally to study the rotor-to-rotor interactions on the aerodynamic and aeroacoustic performance of small unmanned aerial vehicles (UAVs). Two identical rotors, similar to the dimensions of Phantom 3 (DJI), were mounted separately on different stages in a wide-open space. High-accuracy force and sound measurements were conducted to document the thrust and noise at various separation distances. The detailed flow structures and corresponding vortex evolutions behind the rotors were resolved clearly by using high-resolution PIV measurements. As the rotor separation distance decreased, intensified flow interactions were noted within the rotors. More specifically, the twinrotor with separation distance of L= 0.05D exhibited a significantly enhanced thrust fluctuation (i.e., ~ 240% higher) and augmented noise level (i.e., ~ 3dB) in comparison with that of baseline case. Measured PIV results indicated that a strong recirculation region existed near the top-right of the twin-rotor case, which is believed to be the reason for the increased thrust fluctuations and aeroacoustic noise level.

The purpose of our research is to validate an experimental method developed by Johnson and Cowen (2016) aimed at measuring volumetric discharge in an open channel using Surface particle image velocimetry (SPIV) combined with turbulent boundary layer analysis to infer the bathymetry and calculate volumetric flow rate, ultimately extending this work to natural systems (Hendrickson, 2020).
Extending the Frequency Limits of "Postage-Stamp PIV" to MHz Rates
Authors: Beresh Steven , Spillers Russell , Soehnel Melissa , Spitzer Seth
Published: September 2021

The effective frequency limits of postage-stamp PIV, in which a pulse-burst laser and very small fields of view combine to achieve high repetition rates, have been extended by increasing the PIV acquisition rate to very nearly MHz rates (990 kHz) by using a faster camera. Charge leaked through the camera shift register at these framing rates but this was shown not to bias the measurements. The increased framing rate provided oversampled data and enabled use of multi-frame correlation algorithms for a lower noise floor, increasing the effective frequency response to 240 kHz where the interrogation window size begins to spatially filter the data. The velocity spectra suggest turbulence power-law scaling in the inertial subrange steeper than the theoretical -5/3 scaling, attributed to an absence of isotropy.
Shake-The-Box particle tracking with variable time-steps in flows with high velocity range (VT-STB)
Authors: Schanz Daniel , Novara Matteo , Schröder Andreas
Published: September 2021

We present a novel evaluation mode for Lagrangian Particle Tracking methods in general, applied to the Shake-The-Box method specifically. The aim is to attain high levels of accuracy and a removal of false (‘ghost’) tracks in flow situations, where significant amounts of particles show small relative movement with respect to each other in consecutive time-steps.
An iterative approach using variable time separations is employed, which starts by tracking particles at high timeseparations, followed by an iterative reduction of time separation, while feeding the particle tracked within the previous iterations. The process allows for applying tracking parameters fine-tuned to the different flow regimes tracked within each iteration.
Experimental validation was performed using a dataset on impinging jet flow, created in collaboration with the School of Mechanical Engineering of Pusan National University. Evaluation of this flow with high velocity range shows distinct advantages in reduction of ghost tracks and in tracking accuracy.
Investigation of turbulent boundary layer flows with adverse pressure gradient by means of 3D Lagrangian particle tracking with Shake-The-Box
Authors: Novara Matteo , Schanz Daniel , Geisler Reinhard , Agocs Janos , Eich Felix , Bross Matthew , Kähler Christian , Schröder Andreas
Published: September 2021

A large-scale 3D Lagrangian particle tracking (LPT) investigation of a turbulent boundary layer (TBL) flow developing across different pressure gradient regions is presented in this study. Three high-speed multi-camera imaging systems, LED illumination and helium-filled soap bubbles (HFSB) tracers have been adopted to produce time-resolved sequences of particle images over a large volume encompassing approximately 3 m in the streamwise direction, 0:8 m in the spanwise direction and 0:25 m in the wall-normal direction. Individual tracers have been reconstructed and tracked within the imaged volume by means of the Shake-The-Box algorithm (STB, Schanz et al. (2016)); the FlowFit data assimilation algorithm (Gesemann et al. (2016)) has been used to evaluate the spatial velocity gradients and to interpolate the scattered LPT results onto a regular grid. Thanks to the large size of the investigated volume and to the time-resolved nature of the recorded images, the entire spatial extent of the large-scale coherent motions within the logarithmic region of the TBL (i.e. superstructures) could be captured and their dynamics investigated during their development over several boundary layer thickness in the streamwise direction, from the zero pressure gradient region (ZPG) to the adverse pressure gradient region (APG). Two free-stream velocities were investigated, namely 7 and 14m=s, corresponding to Ret ~ 3,000 and 5,000 respectively.
The results confirm the location and scale of the elongated high- and low-momentum structures in the logarithmic region, as well as their meandering in the spanwise direction. Two-point correlation statistics show that the width and spacing of the superstructures are not affected by the transition from the ZPG to the APG region. The analysis of the instantaneous flow realizations from both a Lagrangian and Eulerian perspective indicates the presence of significant fluid particle elements exchange across the interfaces of the large-scale structures.
Moving Surface Actuation, Effects of Frequency-based Shear Layer Excitation on the Response of a Bluff Body Wake
Authors: Singbeil Matthew , Ghiroaga Calin , Morton Chris , Martinuzzi Robert
Published: September 2021

The effect of actuation frequency, using moving surface actuation, is investigated for a square cylinder bluff body wake. Pressure sensor data are used to optimize actuation characteristics through the implementation of an NSGA-II evolutionary algorithm. Velocity field data are obtained using Particle Image Velocimetry (PIV) for baseline and optimized actuation cases. A Proper Orthogonal Decomposition (POD) analysis shows that the vortex shedding frequency shifts between frequencies associated with the actuation, moving between regions of lock-on and quasi-periodicity. Additionally, the POD shows that the energy contained in the coherent shedding motion is reduced through actuation, while the total energy in the velocity field stays relatively constant. A reconstruction of the first 10 POD modes indicates that the coherent contribution to the Reynolds stresses significantly decreases compared to the non-actuated case. The mechanism for drag reduction is investigated using the shed circulation flux and Kochin’s drag formulation model. The drag obtained using PIV measurements and Kochin’s formulation is consistent with trends observed for the base pressure as a function of actuation frequency.

The Covid-19 pandemic has affected various sectors particularly the education sector. The decision by the Malaysian government to close down higher learning institutes and schools has forced educators and teachers to switch their teaching and learning techniques from face-to-face to completely online. This situation has pushed the lecturers from the General Studies Department, Sunway University, Malaysia to master not only the technological tools, but also the pedagogic aspect that drive the entire process, to ensure the teaching and learning process can be carried out properly. Within a short period of time, different methods and modalities were designed and experimented, yet little is known on how such abrupt and rapid modifications affect the overall quality. Considering the value of experiences and reflections, this study probes on the mediated experiences of GSD academics on online teaching and learning, whereby a qualitative-research design was leveraged in a plethora of collective reflections in using E-Learn. The findings revealed that E-Learn has a huge potential to be effectively employed for synchronous and asynchronous modalities due to its user-friendly features and tools within the capacity to disseminate information, structure virtual lessons, record students’ involvement, monitor reports and deploy both formative and summative assessments. This study concluded that the various features of E-Learn had tremendously assisted the GSD lecturers during the online teaching and learning process, and is deemed suitable be used as a platform or Learning Management System (LMS) for online teaching and learning activities.

Published: September 2021

Similar to the learning of most languages, French language is initially learnt through a formal one-to-one classroom. However, the pandemic has given both teachers and students teaching/learning French as a foreign language to accept online learning as the new norm. The success of learning French language online depends on several factors. Both teachers and learners play different roles to make the lessons successful and meaningful. This study is done to investigate how online learning presence is influenced by learners’ motives to study a foreign language. This quantitative study is done to investigate how learners cope learning French online. 170 respondents were purposely chosen from learners who took French as a foreign language. The survey used has 49 items using 5-Likert scales. Findings revealed interesting information about online teaching and learning of foreign languages. The teacher anchors the online lesson with activities well planned and executed. The teacher takes the bulk of the responsibility to make online learning a success. Once the teacher’s and cognitive presence becomes positive, learners can begin to depend on their peers through social presence to maximise the learning experience.
The relationship between manuscripts A, B, D and the marginal readings of manuscript B of Ben Sira
Authors: Rey Jean-Sébastien
Published: September 2021

The relationship between the Hebrew manuscripts of Ben Sira has long been a riddle for scholars. In his seminal article on ‘The Evolution of the Hebrew Text of Ben Sira’, published in 1934, Moshe Segal came to the conclusion that ‘The material provided by these short and fragmentary parallel passages is too scanty to enable us to establish a classification of the Hebrew MSS. on the basis of their textual character.’ In this study I would like to reassess the intricate question of the relationship between the Hebrew manuscripts of Ben Sira by limiting myself to manuscripts A, B and D with special attention to the numerous and characteristic marginal notations of manuscript B and their relationship to other manuscripts.
David Zvi Hoffmann’s (1843–1921) commentary on the Pentateuch in the context of German-Jewish Orthodoxy’s struggle over the dogmatic principles of Torah

The present article explores Rabbi David Zvi Hoffmann’s (1843–1921) exegetical writings – especially his approach to biblical criticism – in the hitherto unexplored context of German-Jewish Orthodoxy’s struggle over the dogmatic principles of Torah. It highlights the parallels and the differences between Hoffmann and other important exegetical protagonists of German Judaism, especially German-Jewish Orthodoxy, as well as the outstanding significance of his enterprise for the latter. Though Hoffmann’s exegetical conclusions conform to a large extent with traditional Jewish exegesis, his methodological principles, his language and the problems he deals with are closely related to contemporary

Authors: ŞAHİNTÜRK Fikret , SÖNMEZ Erkin , ARAZ Çoşkun , AYHAN Selim , YILMAZ Cem
Published: September 2021

Aim:This study aimed to determine whether there is a significant difference between the results of a standard biopsy and Doppler ultrasonography-guided biopsy of the temporal artery, which showed low preoperative pulse pressure.

Material and Methods: Data from 21 patients, who received preliminary diagnosis of temporal arteritis at the neurology clinic were retrospectively investigated. Patients were divided into two groups depending on the method with Doppler ultrasonography and without ultrasonography.

Results: Results from a total of 21 patients were evaluated. The first group consisted of 11 patients who underwent standard temporal artery biopsy, while the second group consisted of 10 patients who underwent ultrasonography-guided biopsy. Six patients in the group without the ultrasonography guidance showed insignificant results. Furthermore, the samples were insufficient in four of these six patients. In contrast, four patients from the Doppler ultrasonography-guided group were diagnosed with arteritis, in addition to the fact that an insufficient biopsy sample was not encountered in these patients.

Statistical analysis showed that there was no significant difference between the pathology results of the two groups.

Conclusion: Although we failed to find a significant difference between the groups, we believe that the Doppler ultrasonography-guided biopsy should be used as a supportive tool rather than diagnostic tool per se, as the Doppler ultrasonography-guided group did not provide insufficient biopsy samples in the pathology results as opposed to the standard group.

A PUSZTA MINT TOPOSZ

A XX. század első felének magyar irodalmában a nagyváros-vidék, központ-periféria Nyugat-Európában is meglévő, egymást kiegészítő toposzai mellett megjelenik a falut vagy kisvárost a pusztával, tanyával szembeállító kettősség. A fenti térreprezentációnak megvannak a maga sztereotípiái, de ennél is fontosabb, hogy egy tágabb, lélektani-antropológiai, társadalmi és végső soron ideológiai kontextusba illeszkedik, ami – a XIX. századi magyar lírából és elbeszélő hagyományból tudatosan építkező – Adytól, Móricztól Szabó Dezsőn át Illyésig, Németh Lászlóig végigkövethető. A fenti diskurzus megteremtésében meghatározó szerepet játszik Móricz Zsigmond prózája a Sáraranytól az Árvácskáig, a Kerek Ferkótól a novellák világáig. Ezek közül is kiemelkedik az Úri muri, ahol Móricz egyrészt rendkívül sokféle módon él a tér jelentésteremtő szerepével: úgy, mint a szereplők konfliktusrendszerét leképező motívummal, mint a hősök lelkivilágát tükröző hellyel, vagy mint a magyar múlt örökségét és a jövő lehetőségeit szimbolizáló formával. Ugyanakkor többféle, néha egymásnak ellentmondó szimbolikus jelentést tulajdonít a toposznak, mélyen merítve annak értelmezéstörténetéből. Ennek következtében rendkívül rétegzett, bonyolult összefüggésrendszer fókuszában áll a puszta képe ebben a regényben. Ugyanakkor tetten érhető Móricznak az a törekvése is, hogy a jelkép egymásra rakódó rétegei közt – ha nem is mindig kifejtve, néha csak sejtetés formájában – összefüggést teremtsen. E bonyolult jelentéskomplexum alkotóelemeinek szétválasztása, eszmetörténeti forrásainak feltárása, a Móricz által köztük teremtett kapcsolatok felfejtése lesz a tanulmány témája.

Sinema, ekonomik büyüklüğü ile yapım, dağıtım, gösterim şirketlerini, bu şirketlerde çalışan bireyleri ve tüketici konumundaki sinema seyircisini ilgilendiren büyük bir endüstridir. Geniş kitlelerle ilişkili olan bu büyük endüstrideki işleyiş, Çin’in Wuhan kentinde ortaya çıkan Covid-19 salgını sonucunda alınan önleyici yasaklar ile tamamen durma noktasına gelmiştir. Pandemi kapsamında alınan önlemlerle birlikte, ABD ve Çin başta olmak üzere dünya genelinde sinema endüstrileri zarar görmüş ve bu zarardan Türk sinema endüstrisi de etkilenmiştir. Bu etkinin oluştuğu varsayımından yola çıkılarak Covid-19 salgınının, Türk sinema endüstrisi üzerinde yaratmış olduğu krizin ekonomik etkilerini ortaya koymak çalışmanın amacı olarak belirlenmiştir. Bu amaç doğrultusunda Türkiye’de 2015-2020 yılları arasındaki seyirci sayısı, film hasılatları, sektörde çalışan sigortalı işçi sayısı, sinema salonu ve koltuk sayısı kategorilerinde sinema sektörüne ilişkin değişkenler doküman incelemesi tekniği ile değerlendirilmiştir. Değerlendirme sonucu ortaya çıkan bulgular, Covid-19 sürecinde Türk sinema endüstrisinin ekonomik kayıplar yaşadığını ve kırılgan bir yapıda olduğunu ortaya koymuştur. Bu doğrultuda, mevcut krizin aşılması ve ileride yaşanabilecek olası krizlerin oluşturabileceği zararların azaltılması adına, sektörde reaktif ve proaktif yaklaşımların etkin şekilde kullanılması önerilmiştir.

O avanço tecnológico impacta no aumento do consumo de bens e, consequentemente, no aumento de resíduos inutilizáveis. Com isso surgem problemas quanto ao descarte incorreto de materiais que podem degradar o meio ambiente. Neste sentido, o objetivo desta pesquisa baseou-se em identificar as contribuições sociais e ambientais dos recicladores e dos ferros velhos para os canais reversos de resíduos sólidos. A partir de entrevistas com sucateiros, gestores de ecopontos, ferros velhos e pesquisa documental nas cidades Limeira e Itapetininga, ambas localizadas no Estado de São Paulo, foi observado a diversidade sociodemográfica dos indivíduos atuantes no ramo da reciclagem, os quais realizam a coleta de quantidades consideráveis de resíduos sólidos do ambiente urbano, cuja renda advinda da atividade é utilizada para fins de sobrevivência. Assim, pode-se concluir que os catadores compreendem os benefícios ambientais e sociais de suas atividades. Os atravessadores, por sua vez, promovem mudanças econômicas pessoais aos agentes coletores de forma a propiciar um ambiente de negociação dos resíduos mais favorável. Com as descobertas deste estudo, espera-se aumentar a consciência da importância desses agentes no meio social – inclusive para o desenvolvimento sustentável – por parte de órgãos públicos e privados a fim de garantir melhores estruturas de trabalho destes catadores.

Buscar alternativas para reduzir os impactos ambientais oriundos das atividades produtivas são preocupações na sociedade moderna. Como parte importante desse processo, os governos de alguns países têm procurado mitigar estes impactos, utilizando como estratégia o seu poder de compras, com a aquisição de produtos e serviços que causem o menor dano ambiental possível. O objetivo deste artigo é analisar os avanços das pesquisas sobre Compras Públicas Sustentáveis (CPS), antes e depois da Conferência das Nações Unidas sobre Desenvolvimento Sustentável (Rio+20), realizada em 2012, no Brasil. Quanto aos procedimentos metodológicos, em relação à abordagem do problema é qualitativo. Quanto aos objetivos é uma pesquisa descritiva. Os procedimentos utilizados para a coleta e análise dos dados foram técnicas de bibliometria e análise de conteúdo. Inicialmente foi realizada uma leitura flutuante para explorar os artigos e posteriormente foram analisados conforme características propostas por Bardin (2010): Exaustividade: onde todos os elementos que correspondiam aos critérios incluídos foram considerados; Representatividade: a análise foi feita com uma amostra representativa; Homogeneidade: os critérios para as escolhas foram feitos com técnicas idênticas e; Pertinência: certificou-se de que os dados estavam adequados em relação às fontes de informação. Os achados da pesquisa demonstraram que o campo está em desenvolvimento, embora sob o ponto de vista acadêmico ainda não atingiu a maturidade, pois importantes aspectos relacionados às compras públicas sustentáveis ainda têm sido negligenciados, visto a importância que essa temática representa no atual contexto global.

O descarte irregular de resíduos sólidos pode gerar danos significativos para o ecossistema, poluindo as águas subterrâneas, impactando nichos ecológicos, e causando perda de biodiversidade, entre outros. Diante deste cenário, o presente estudo teve como objetivo investigar como tem sido feita a gestão de resíduos sólidos em Unidades de Conservação (UC). Para tal, foi realizado um levantamento dos planos de manejo de 32 UC, de um total de 55 situadas no Estado do Rio de Janeiro. Com esses dados torna-se possível sugerir estratégias de manejo e de educação ambiental na gestão de resíduos sólidos em outras UC administradas pelo Instituto Chico Mendes de Conservação da Biodiversidade (ICMBio). Como também em áreas de preservação de outros países que ainda não têm ações concretas sobre este tema. A partir desta análise, foram identificadas ações relacionadas com gestão de resíduos sólidos que estão alinhadas com a  Lei nº 12.305/10, que instituiu a Política Nacional de Resíduos Sólidos (PNRS), e que podem vir a ser implementadas em outras UC, como por exemplo,  a  instalação de lixeiras de coleta seletiva, a realização de campanhas educativas sobre resíduos sólidos em dias de alta visitação e a avaliação e monitoramento dos diferentes tipos de resíduos e as suas consequências para o meio ambiente a fim de compatibilizar o uso público com a preservação ambiental.
INVESTIMENTOS EM ENERGIA ELÉTRICA E DESENVOLVIMENTO: UMA ANÁLISE HISTÓRICA ENTRE 1995 E 2005 NO PARÁ, BRASIL
Authors: Borges Fabricio Quadros
Published: September 2021

A energia elétrica detém papel estratégico neste processo na medida em que pode contribuir ao melhoramento de vários setores essenciais como saúde, educação, alimentação, água e saneamento. Este artigo possui o objetivo de compreender os reflexos dos investimentos em energia elétrica junto ao processo de desenvolvimento no Pará, por meio dos setores de atividade econômica. A metodologia utilizada neste ensaio fundamentou-se a partir da identificação de correlações lineares entre variáveis vinculadas a energia elétrica e ao processo de desenvolvimento no setor industrial; e a partir da análise crítica da interferência das sinergias setoriais provocadas por estas correlações junto a dinâmica dos investimentos no setor elétrico. O estudo concluiu que os investimentos em energia elétrica, embora em curto prazo possam ocasionar efeitos direcionados na promoção da atividade econômica de determinada região ou país, tendem, em médio e/ou longo prazo, a distorcer as bases sustentáveis de promoção da melhoria do padrão de vida das populações na medida em que o efeito dos investimentos em energia elétrica é uma função das sinergias oriundas do perfil de cada setor econômico, das especificidades regionais verificadas e das políticas setoriais implantadas.

Os stakeholders pressionam as empresas para que elas assumam a responsabilidade ambiental, nesse sentido a gestão e certificação ambiental tornam-se um diferencial na construção de uma imagem positiva do negócio. Assim, o presente trabalho tem como objetivo analisar a adoção da certificação ambiental como estratégia empresarial em empresas de gerenciamento e descarte de resíduos sólidos. Para tanto, foi realizado um estudo de caso em duas empresas do Vale dos Sinos/RS cujos dados foram coletados através de pesquisa em sites institucionais e mídias sociais das empresas analisadas, além da aplicação de um questionário com questões abertas sobre o Sistema de Gestão Ambiental (SGA) e certificação. Os resultados mostram que as empresas percebem o SGA e a certificação ISO 14001 de grande importância para o reconhecimento do empreendimento no mercado, entre as estratégias para adoção da certificação estão o reconhecimento da marca, a prospecção de clientes e a competitividade de mercado.
