This project aims to develop an enzymatic route for biodiesel production, using ethanol and palm oil as raw materials. Currently, biodiesel is obtained by a chemical reaction between an oil and an alcohol, accelerated by a chemical catalyst - mainly sodium hydroxide. The use of this catalyst, however, causes a number of problems, such as high energy consumption, difficult glycerol recovery and the generation of a large volume of effluent. In addition, it causes saponification when acid oils, suc

Focusing on the development of the Canola production chain in the Federal District and surroundings, Embrapa Agroenergia closed a partnership with Cooperativa Agrícola do Rio Preto (Coarp) for the execution of the project "Sustainable production system for the cultivation and processing of Canola oil in the Cerrado with a focus on the bioeconomy (Procanola). In the first year of the project (2021), an average productivity of 2 thousand kg/ha was reached, above the Brazilian average, which is 1,4 ...

One of the main post-harvest problems is the emergence of spoilage in oranges caused especially by fungi that depreciate the quality and decrease shelf life and may also compromise food safety. Various treatment technologies such as: modified atmosphere, irradiation, anti-microbial ice and high pressure, among others, have been studied in the quest to eliminate food pathogens. Thus, understanding mechanisms of microorganism control in foods have been the topic of intense research with the use of

This partnership proposal will seek to implement and monitor experimental units for recomposition of Permanent Preservation Areas (APP in Portuguese) around the UHE Sinop reservoir, watershed of the Teles Pires river, Mato Grosso. With the filling of the reservoir of UHE Sinop, carried out in the first two months of 2019, the entrepreneur (Sinop Energia) was imposed, via condition requested by the environmental agency responsible for inspection, the environmental regularization of the Permane

In Brazil, milk production is practiced by more than one million farmers, mostly smallholders, who have the most important sources of feed for the herd in pasture and forage grass cropping for cut-and-carry. One of the major demands of farmers is on improved forage cultivars for cutting and grazing that can meet the nutritional needs of herds throughout the year. Elephantgrass, in addition to its superior performance in the establishment of cut-and-carry plantations (i.e. green chopped, hay, and

The state of Pará is responsible for 80% of the national black pepper production, and Brazil is the third biggest producer and exporter of the spice. However, the production and productivity of the culture has been decreasing throughout the years due to the occurrence of the root rotting disease caused by Fusarium solani f sp. Piperis in a great number of black pepper farms, leading to great economical loss and substantial decline in plantation area along the period of more than forty ye ...

Pasture as an exclusive feeding source accounts for almost 90% of the beef consumed in Brazil and for most of the nearly 35 billion liters of milk produced annually in the country. It is estimated today that, in Brazil, grasses of the genus Brachiaria are cultivated in approximately 84 million hectares. In Brazil, the most cultivated species of Brachiaria are B. decumbens, B. brizantha, B. humidicola and B. ruziziensis. With the increasing agricult ...

In the ethanol manufacturing process, the plants demand a large amount of biomass for burning and heat generation, consequently generating a significant amount of ash. Naturally, this residual material needs to have an adequate final destination, in order to avoid polluting the environment and also, to take advantage of the nutrients contained in the ashes. The composition of the ashes varies greatly, as it depends on the quality of the wood and also on the operating conditions of the boilers. A

Waste recycling is common in agriculture nowadays on different scales, depending on chain organization, available technologies, and environmental and health regulations. Just to mention two figures, in 2009 the sugarcane-ethanol chain produced 604 billion liters of vinasse and 201 million tons of bagasse and filter cake. Although the bagasse is burnt to generate energy and the vinasse is a fertilizer, many challenges remain. The objective of this project is to assess the potential to transfor

The manual harvest of pepper fruits is difficult mostly due to the plants' low heights and the fruit's pungency, which causes irritation and burns the hands of harvesters. Such aspects partly explain the scarcity of labor for the pepper harvest. In addition, in the Brazilian and international market there are no jalapeño cultivars developed for mechanized harvesting. Therefore, this project aims at the development of new jalapeño cultivars adapted to mechanized harvest - with suitable plant arch ...
