ABSTRACT
Objective: to calculate the minimum number of animals that a rural pig farm needs to raise so that the implementation of biodigesters to generate clean energy in the context of Brazil is financially viable. Theoretical framework: a more efficient productive farm tends to include environmentally sustainable actions, since pig farming is considered a relevant activity of environmental concerns due to the amount of manure produced, especially in an intensive system. It is in this context that several current studies have been debating the environmentally correct reuse of pig manure. Method: using interviews and exploratory searches, data were collected that projected the project's cash flow. From this, the number of animals needed for the net present value of the project to be zeroed was calculated. Also, the probabilistic scenario was designed using the Monte Carlo Simulation. Results and conclusion: for the deterministic scenario, it was calculated that 736 animals are needed for zero/null NPV and for a probabilistic scenario context with p(NPV<0) = p(IRR<TMA) = 0.2, it is necessary that the rural property has at least 840 animals. Research implications: the academic and social contribution of this work is that it can help small swine producers in their decision-making for the implementation of biodigesters. Originality/value: considering rural activities as strong polluters and the large increase in electricity tariffs seen in recent years, mainly due to severe droughts and the COVID-19 pandemic, the reuse of waste becomes increasingly important and relevant for clean and distributed energy generation. © 2023 ANPAD - Associacao Nacional de Pos-Graduacao e Pesquisa em Administracao.

ABSTRACT
Purpose: The aim of this article is to explore the barriers imposed by the COVID-19 pandemic to Participatory Budgeting (PB), considering the perspective of Brazilian and Portuguese Local Public Administration. Theoretical framework: Recent literature points out that the barriers imposed on PB processes arising from the crisis of the COVID-19 pandemic are justified by many leaders due to social distancing measures and the expansion of financial constraints. Design/methodology/approach: An online questionnaire was applied using a Likert-type scale to assess the perception of public officials, in Paraná and Portugal, about the barriers imposed by the COVID-19 pandemic to PB. Through a quantitative approach, data were presented and analyzed using descriptive statistics and the Chi-square test of adherence. Findings: The survey contributors from the Portuguese municipalities indicated that the crisis caused by the COVID-19 pandemic had a negative impact on the conduct of PB processes. The possible restrictive consequences caused by the COVID-19 pandemic on the realization of PB in the future are not clear, according to the responses obtained in the two contexts analyzed. Research, Practical & Social implications: Future studies may include the perspective of the participants in the process and the possible reduction in the amounts available for the execution of the PB due to the pandemic of COVID-19. Originality/value: COVID-19 alone cannot bring citizens to the periphery of public policy decisions. Difficulties prior to the pandemic, such as the absence of an online platform contributed to limiting the participatory space. © The Author(s), 2022.
