(2024-07-24) Soares, Guilherme Bastos; Pragana, Rossanna Barbosa; http://lattes.cnpq.br/8705453663044944; http://lattes.cnpq.br/7776540361160364
Greenhouse gas (GHG) emissions have always occurred naturally on Earth, but global concern about anthropogenic emissions began in 1979, with the holding of the first world climate conference. After that, several agreements were created with the aim of reducing emissions of these gases, such as Eco-92, the Kyoto Protocol and the Paris agreement, which established goals for reducing GHG emissions. Accounting for these gases is a way of quantifying emissions from activities carried out in a company or organization, therefore, the study aimed to map the activities carried out at CEASA/PE, seeking methods to quantify the emissions generated, such as through the calculation of the GHG Protocol, which condenses the emission factors calculated for each process according to the year in which the emissions will be recorded. For the calculations of emissions avoided in the composting process, the AMS-III.F tool was used, making a comparison with emissions arising from the waste landfilling process. With the calculations carried out, it was possible to observe that CEASA had a total of 13.481,24 tons of CO2-eq emitted in the year 2023, with the composting process at CEASA-PE avoiding the emission of 8,108 tCO2-eq, when compared to landfilling. of the same waste. Furthermore, it is observed that if all organic waste were composted by the center, the avoided emissions could reach up to 22,656.9 tCO2-eq, demonstrating the potential of composting to reduce GHG emissions. Furthermore, the study notes that composting is an important contributor to the reduction of GHG emissions, requiring the implementation of broader and more controlled composting processes. It is recommended that there be more studies related to the transport of waste to optimize the effectiveness in reducing composting projects.

(2023-04-26) Silva, Juliana Lima da; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/1031733290570454
According to the Ministry of the Environment, in Brazil, in 2017, about 55% of the waste produced is composed of organic waste and the current disposal of this waste in the environment has been responsible for deleterious impacts on man and the ecosystem. Composting is one of the most effective means of recycling organic waste, as in addition to being a sustainable way of disposing of this waste, the use of its by-product in the soil can keep acidity levels stable and favor agricultural practices. There are different composting methods, with domestic composting being an advantageous alternative for the treatment of the organic portion of household waste, since the installation of the system and the use of the final compost takes place in the same place where the waste is produced. The final organic compost is a material rich in macro and micronutrients, with satisfactory application, as fertilizer or fertilizer, in horticulture. Organic horticulture is intended for the cultivation of vegetables, legumes, grains, among other healthy foods that contribute to the health and well-being of its users. In this context, the objective of this work was to study domestic composting as an instrument of environmental sustainability and improvement of the quality of life.

In front of the great increase in the generation of urban solid waste, recurrent of the disordered population growth, a composting is taken as an alternative for the treatment of the organic waste fraction. In this context, the objective of this research was to evaluate a domestic composting of solid waste from a residence, using the compost produced in the cultivation of collard greens seedlings and employing domestic composting and the practice of horticulture as a sustainable and productive activity, which induces physical and mental well-being in a pandemic period. The composting process lasted 120 days and was carried out in a designed mini composter. The organic compost produced was used to obtain seedlings of two collard greens species. The sowing was carried out in a tray with fifteen cells, set up in a completely randomized design, with five treatments and three replications. The applied treatments, T0, T1, T2, T3 and T4,corresponded, respectively, to 100% soil; 75% soil and 25% fertilizer; 50% soil and 50% fertilizer; 25% soil and 75% fertilizer and 100% fertilizer. They were avalueted: germination time, leaf length, leaf width, number of leaves, seedling height, root length and stem diameter. Treatments T2, T3 and T4 showed the best performances, with treatment T2 being the one with the best results for Brassica oleracea var. Costata and treatment T3 for Brassica oleracea var. Acephala. In addition, the study was assessed as adequate by the process participants, as it aroused interest, sustainable learning and productive routines, directly influencing the maintenance of well-being during pandemic period
Impacto socioeconômico da compostagem doméstica em uma comunidade indígena no município de Baía da Traição/PB
(2022-10-10) Padilha, Francis Bezerra; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/7935712126036066
The generation of waste, of all its typologies, represents a problem for the whole society, not being restricted only to Brazil. Its disposal and destination have been objects of study, in order to minimize and/or solve the impacts caused by the mismanagement of these wastes. Organic matter represents a large portion of urban solid waste in Brazil and, therefore, its treatment is essential for the reduction of material to be sent to landfills or to another destination. An environmentally correct destination is the use of organic fertilizer resulting from composting in agriculture. Thus, the present study sought to evaluate the socioeconomic impact of home composting in an indigenous community in the municipality of Baía da Traição/PB. The residues used in the process were cassava peel and dry cashew leaves in a C/N ratio of 30:1. The resulting organic fertilizer was used in the planting of lettuce, reaching the production of 350 feet in one cycle; and a sales profit of R$1050.00 reais. This practice can strengthen and promote local development in the indigenous community, making the circular economy from agriculture. On the other hand, the work sought to influence the environmental awareness of the population by offering a lecture on the importance of home composting in the social context. In this way, the positive impact of composting on the community was observed, either in the financial aspect or in the educational aspect.
Proposta de modelo gerencial de compostagem para condomínios verticais: estudo de caso na cidade do Recife - PE, Brasil
(2023-04-05) Silva, Rafaela de Sá Oliveira; El-Deir, Soraya Giovanetti; http://lattes.cnpq.br/3202139188457904; http://lattes.cnpq.br/4176982333424244
The verticalization of cities, although maximizing urban spaces, entails negative environmental impacts that need to be mitigated. Every day, millions of tons of organic waste are discarded due to the lack of environmental responsibility on the part of civil society, public authorities and private entities. In this way, it is essential to seek individual, shared and cooperative solutions that avoid the inappropriate disposal of organic waste. From this perspective, the objective of this project is to structure a proposal for a management model for composting organic waste for vertical condominiums. The methodology consisted of a documentary and bibliographical survey and the structuring of a management model based on services provided by a solid waste management company. The primary data were obtained through a vertical condominium located in the city of Recife-PE. The results consist of the development of steps that include contact with the tenants, data collection through collections and questionnaire, analysis of primary data, development of support material, determination of the administrative-managerial model and pricing. These stages were developed in such a way that they can be replicated in collection and composting companies that aim to start or improve their services in condominiums, since the model respects the particularities of the structure, local administration and co-ownership of the residences. We sought to standardize and automate most of the process, as the professional responsible for development may have several simultaneous projects.
