Waste from Electrical and Electronic Equipment (WEEE) is the widest and fastest-growing source of global waste, yet only around 17% of the total generated volume is formally recycled. In Brazil, policies have established the concept of Shared Responsibility as a crucial strategy for increasing recycling rates and achieving Circular Economy (CE) goals. Although there are laws that regulate WEEE through Shared Responsibility principles, companies must engage people to participate in reverse chain logistics. This study performed Action Research (AR) to understand how a WEEE recycling company can engage society and increase the amount of waste that is collected and treated. A collection campaign was tested as a strategy for this purpose, for a specific population, and referencing the specific Reverse Logistics (RL) system offered by the company studied. Furthermore, usability analysis for the company's RL online platform was conducted to verify how easily end users can use this channel. The results of this AR showed the importance of establishing a close relationship between companies, and society at large, to collect and recycle WEEE. Collection campaigns are a powerful way of constantly generating awareness among the populace. Finally, we were able to conclude via this AR, that all stakeholders are essential if the WEEE reverse chain system is to succeed. Companies need to have a way of reaching end users, maintaining continuous feedback, and providing easier ways for freely disposing of waste. Additionally, governments must support the private sector in raising end-user awareness and promoting education. [ABSTRACT FROM AUTHOR]

Bat-borne viruses may affect public health and the global economy. These mammals have a wide geographical distribution and unique biological, physiological, and immunogenic characteristics, allowing the dissemination of many known and unknown viruses. Enteric viruses, such as adeno (AdV) and rotaviruses, are recognized as the main causative agents of disease and outbreaks. In the present study, the presence of viruses from Adenoviridae and Reoviridae families was evaluated in molossid, phyllostomid, and vespertilionid bats captured in Rio Grande do Sul, Southern Brazil, between September 2021 and July 2022. Sixty bat rectal swabs were analyzed by PCR. Eight (13.3%) samples were positive for adenovirus and classified as human mastadenovirus C (HAdV-C) (three samples) and HAdV-E (five samples) by sequencing followed by phylogenetic analysis. All samples were negative in rotavirus specific RT-PCR. This is the first study to describe the presence of HAdV in samples of Glossophaga soricina, Eptesicus brasiliensis, and Histiotus velatus. Furthermore, the presence of HAdV-E in bats was reported, which is unusual and may suggest that other HAdV genotypes, in addition to HAdV-C, may also be harbored by wild animals. The data generated in the present study reinforces the importance of eco-surveillance of viral agents related to diseases in humans and wild animals. In addition, it is essential to identify possible new hosts or reservoirs that increase the risk of spillover and dissemination of infectious pathogens, helping to prevent and control zoonotic diseases., (© 2024.
