Item Vermicompostagem como tecnologia aplicada no tratamento de resíduos da agroindústria de polpas de frutas tropicas: uma breve revisão(2024-03-01) Silva, Almir Mendes da; Nunes, Ramom Rachide; http://lattes.cnpq.br/6182302726895126; http://lattes.cnpq.br/0859445695330939Vermicomposting is an environmental technology applied to the treatment of organic waste, converting it into an agricultural input with high agronomic potential, produced from the combined action of earthworms and the microorganisms that live in their digestive tracts. In this process, earthworms feed on organic waste and excrete a material called vermicompost, rich in nutrients and microorganisms beneficial to the soil-plant system. The chemical attributes of vermicompost improve soil structure, increase its water retention capacity and promote microbial activity. This environmental technology has several advantages, as it is an efficient and sustainable way of recycling organic matter and nutrients, as well as mitigating the environmental impacts caused by waste that ends up in landfills or is abandoned in the field. Among the waste that is a cause for environmental concern, specifically tropical fruits: yellow mombin, Guarani cherry, and Brazilian cherry (main Brazilian native tropical fruits). Furthermore, by-products from fruit processing are not reused due to their lack of commercial value and can cause several environmental problems when disposed of inappropriately. Thus, this work aimed to carry out a bibliographical review on the originality of the project, as well as the possibility of vermicomposting the by-products of fruit pulp processing, comparing this study with others found in the literature. As a result, no studies were found in which yellow mombin, Guarani cherry, and Brazilian cherry waste are vermicomposted, giving originality to the proposal. Furthermore, studies with similar fruits, reported in the literature, indicate the possibility of vermicomposting the aforementioned residues, producing an input with high agronomic potential, suitable for use in organic and ecologically based agricultural systems.Item 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/4176982333424244The 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.Item Vivência na Secretaria Executiva de Agricultura Urbana do Recife: implantação e acompanhamento do pátio de compostagem municipal(2021) Bomfim Júnior, Heleno da Silva; Gonçalves Neto, Álvaro Carlos; http://lattes.cnpq.br/1044585519530220Item Recuperação e purificação parcial de proteases colagenolíticas de tainha (Mugil liza) usando precipitação e particionamento em sistemas de fases(2020-02-03) Costa, Beatriz de Aquino Marques da; Porto, Ana Lúcia Figueiredo; http://lattes.cnpq.br/4989617783837981; http://lattes.cnpq.br/2650705679652460Proteases play an important role in the field of biotechnology studies, which is why the research for alternative sources is highly desirable. Thus, combining extraction, recovery and purification techniques to alternative sources, such as by-products of the fishery production chain, in order to generate the least possible damage to the aquatic environment is profitable for the global enzyme market. Therefore, the objective of the present work is to partially recover and purify collagenolytic proteases from Mullet (Mugil liza) digestive viscera with potential biotechnological application. For this, the digestive viscera extract (intestine, liverand a mixture of various viscera) was precipitated using ammonium sulfate ((NH4) 2SO4). In addition, the intestinal viscera were submitted to partitioning by an Aqueous Two-Phase System (ATPS) and a Three-Phase Partitioning system (TPP), to evaluate the most beneficial conditions for the purification of collagenolytic proteases. The results obtained demonstrate that, for ammonium sulphate precipitation, the best results of Purification Factor occurred in concentrations of 30-60% for all assessed extracts (intestine, liver and mix); the aqueous two-phase system (PEG/Citrate) carried out with Mullet intestinal viscera extract demonstrates that the conditions: PEG of 8000 g/mol molar mass; 20% concentration of PEG; 15% citrate concentration lead to the highest purification factor. It is also observed that the collagenases tend to migrate to the PEG-rich phase; for the three-phase system (t-butanol / (NH4) 2SO4) the highest recovery rate of collagenolytic protease was observed in the proportion of 1:0.5, obtaining recovery of 240.01% and a purification factorof 2,55. Thus, it is concluded that the tests can be used in the recovery of biomolecules from neglected organic solid waste from the fishing industry.Item Caracterização da uva BRS vitória visando o aproveitamento energético(2019) Polycarpo, Julyane Silva Mendes; Beltrame, Leocádia Terezinha Cordeiro; Silva, Sérgio Peres Ramos da; http://lattes.cnpq.br/5952171958668242; http://lattes.cnpq.br/1127762636779912; http://lattes.cnpq.br/6485220445197373
