O biodiesel e considerado uma alternativa aos combustiveis fosseis, porem a oleaginosa mais utilizada na producao deste biocombustivel e a soja que esta inserida na cadeia alimentar humana, assim ha necessidade de se estudar materias primas alternativas. A erva daninha Cyperus esculentus pode se tornar uma alternativa para a producao de biodiesel, mas para tal necessita de um estudo abrangente relacionado a fatores ambientais, economicos e sociais. O objetivo deste trabalho e realizar um estudo viabilidade economica ambiental e social da producao de biodiesel a obtido pela transesterificacao do oleo de Cyperus esculentus. A Analise de Custo Beneficio Economico Socioambiental, ACB, foi realizada com o intuito de se obter dados referentes aos fatores ambientais, sociais e economicos. A producao de biodiesel a partir da oleaginosa Cyperus esculentus e viavel economicamente, alem de contribuir para a agricultura familiar e minimiza os impactos ambientais relacionados ao uso de agrotoxicos e a area de cultivo ser menor com um mesmo rendimento, comparado com a soja. Abstract Biodiesel is considered an alternative to fossil fuels, but the crop most used in the production of this biofuel is soy, that is inserted into the human food chain, so there is no need to study alternative raw materials. The weed Cyperus esculentus can become an alternative for the production of biodiesel, but this requires an extensive study related to environmental, economic and social. The objective of this research is to perform a study of the economic, environmental and social viability of the production of biodiesel obtained from the transesterified Cyperus esculentus oil. The socioenvironmental and economic cost-benefit analysis (CBA) was performed in order to obtain data related to social and economic factors. The production of biodiesel from the oil seed Cyperus esculentus is economically viable. It contributes to the family farm, minimizes environmental impacts related to pesticide use and the required cultivation area is lower the cultivated area is smaller with the same performance, compared to the soybean.
