A product-service-system proposal for municipalities in developing countries with tight budget to convert the organic waste in energy to eliminate dumps.

In developing countries, organic waste is commonly dumped in untreated landfills. Brazil has around 3,000 landfills distributed in 1,600 cities. The Brazilian government instituted the National Solid Waste Policy (PNRS), which set the goal of ending the dumping grounds in 2014. However, it was not accomplished. Municipal governments do not have the resources to fund the existing treatment technologies. Thus, there is an urgent need to propose low-cost alternatives to solve this problem. This work proposes a low-cost Product-Service System (PSS) solution that enables the proper treatment of organic waste using the current municipal budget, based on the renting of household biodigesters. It was outlined from a model built on various proposals for the PSS design, published between 2011 and 2018. A feasibility simulation of the proposal conducted for the scenario of the Brazilian city of Porto Amazonas has demonstrated that, by adopting the proposal, the administration could comply with the PNRS and save part of its actual budget. It also showed 75% of probability of financial viability for the PSS provider, in a scenario of reduction of up to 20% in the current municipal costs for organic waste collection and transportation, and up to 40% off in cooking gas costs for the equipment-hosting households. The proposal is a potential solution for the Brazilian municipalities with more favorable scenarios to comply with the PNRS, as well as other countries' municipalities with budget constraints to eliminate their dumps.

Percepção e atitudes do ser humano sobre guarda responsável, zoonoses, controle populacional e cães em vias públicas / Perception and attitudes of the sample population on responsible custody, zoonosis and stray dogs

O presente trabalho teve por objetivo avaliar a percepção sobre guarda responsável, zoonoses, controle populacional de cães e gatos e a situação de cães de rua, de uma amostra de pessoas pertencentes à Pontifícia Universidade Católica do Paraná. Para isso foram enviados questionários online com 22 perguntas. Participaram dessa pesquisa 239 pessoas, a maioria do sexo feminino, com faixa etária entre 25 e 35 anos, com ensino superior completo, residentes principalmente em Curitiba/PR. Possuíam cão ou gato como animal de estimação, 57% dos respondentes, e em relação à quantidade de animais por respondente, o número médio de cães foi de 2,62 ± 1,35 e gatos de 1,56 ± 1,07. Tanto proprietários de cães como gatos, afirmaram praticar com regularidade a vacinação, administração de vermífugos e atendimento veterinário de seus animais. O acesso dos cães à rua foi realizado com coleira e guia por 50,53% dos respondentes. Em relação à zoonose, 62% afirmaram saber o que é e conseguiram citar um exemplo. Sobre a presença de animal solto no seu bairro, 78% dos respondentes afirmaram que sim, 49% observaram que há cães de rua que são mantidos por alguém e 71% afirmaram que o responsável pelo controle desses animais deve ser o governo e a sociedade. Diante das respostas obtidas, foi possível identificar que essa amostra populacional reconheceu seis tipos de zoonoses, percebeu a importância da guarda responsável de cães e gatos e afirmou que não haja um único responsável pelos cães de rua.
