    Aterros sanitários: tratamento e aproveitamento do biogás em três capitais do nordeste brasileiro

    Sanitary landfills are one of the solutions to the problem of final disposal of urban solid waste. The decomposition of organic matter in the waste generates, among other components, Biogas, this can be used for the production of renewable energy. With the growing demand for renewable energy sources, new studies must be carried out to increase knowledge about the development of the energy sector, especially in the Biogas sector. This study aims to analyze and compare the Biogas Management Systems in three sanitary landfills in Northeastern Brazilian capitals (Aracaju, Natal and Fortaleza). Data collection was carried out through a seventeenquestion virtual questionnaire, aimed at companies responsible for managing the landfills. Only one of the landfills has an energy recovery system, producing renewable natural gas, disappointing results for the current scenario. However, the feasibility demonstrated in the landfill that produces Renewable Natural Gas -NGR and distributes it to the piped network, is a great incentive for other landfills to envision the possibility of implementing similar systems. Despite not producing GNR, the other landfills have shown interest in biogas-fired thermoelectric plants, so this scenario can be changed in the future.

    This work aimed to analyze the use of pesticides in rice plantations in Ipiranga, a village of Igreja Nova, AL, and the impacts generated in the lives of farmers and the environment. Its methodology was composed of two parts, among them a descriptive qualitative research with the completion of a questionnaire and a field visit, in which interviews were conducted with farmers who cultivate rice. When asked about the use of pesticides and the types applied, 100% of respondents said they use such technology, and all use herbicides, 95% use insecticides and 5% use fungicides. About 74% of the interviewees stated that they receive guidance on the use, and the care that should be taken, and the other 26% stated that they do not. When we asked about the storage and disposal of the packages: for the first, 79% stated that they have a specific place for its storage, 16% stated that they have a shed, but not specific for its storage, and 5% stated that they store them in the back of the house; for the second, 5% stated that the packages are collected by the store where they bought the substances, 32% stated that they are collected by the district, 5% stated that they deliver them to one of the aforementioned, 5% keep these packages, 16% throw them in the conventional garbage, 5% keep them, and 37% incinerate them. Regarding the use of some personal protective equipment (PPE), 74% said they used it and 26% said they did not, the most used being: mask (57%), gloves (43%), long pants and closed (43%), long sleeve shirt (29%), boots (21%), hat (21%), and cape (7%). Of those who did, the most common symptoms were: headache (50%), dizziness (50%), skin irritation (37.5%), nausea (25%), chest pain (25%), sleepiness (25%), decreased vision (12.5%), and pain on one side of the body (12.5%). Regarding damage to the environment, 100% of the farmers said that they did not notice any difference in the local vegetation, in the quantity and variety of animal species, and in the quantity and quality of water. In conclusion, farmers use pesticides in their rice fields, even though they have minimal knowledge about their harmful effects. This work suggests the need for public rural assistance policies to make farmers more aware of the use of pesticides in crops.
