| The process of organic waste biodigestion is quite old, as the first unit was installed in Bombay, India, in 1819; in Australia, a company has produced and industrialized methane from sewage since 1911. China has 4.5 million biodigesters that produce gas and organic fertilizer, the main role of which is sanitation in rural areas. However, different aspects related to biodigesters are still lacking. This work aimed at studying and improving a biodigester system, and its general goal was the devel Status: Completed Start date: Sun Apr 01 00:00:00 GMT-03:00 2007 |

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 ...Status: Completed Start date: Wed May 01 00:00:00 GMT-03:00 2013 |
| The main environmental problems associated with the waste produced in intensive pig farming are its high organic load, high amount of nutrients, the presence of some metallic species and of micro-organisms, some of which are known pathogenic agents. In general, the waste treatment systems in pig farms still lack the ability to reduce or eliminate pathogenic agents from the waste produced, a fact which makes it difficult to reuse the water in the very facility or even in agriculture.

| The adoption of Good Laboratory Practices (GLP) contributes to the development of scientific research, as they result in greater reliability and efficiency of the results. In order to follow some of the current standards, such as GLP or ISO 17025, the laboratory must adopt measures of organization, control, training, standardization and registration of its activities. The laboratory must also adopt practices that guarantee the safety of its personnel and the community in general. Among these is Status: Completed Start date: Tue Jul 01 00:00:00 GMT-03:00 2008 |
| The overall objective of this project was to strengthen Brazil’s green economy by harmonizing economic development and environmental conservation through sustainable agriculture that does not harm the environment, using soil and plant biomass management in organic production systems as a starting point. Unlike many agricultural production systems, organic agriculture offers a range of practices and techniques that potentially contribute to increase sustainability, including soil and plant biomas Status: Completed Start date: Sat Sep 01 00:00:00 GMT-03:00 2012 |
| This project aimed to present reuse alternates for the waste produced in the industrial processing of açaí, and thus obtain processing plants that minimize the release of waste products. A previous evaluation of this matter pointed out technological alternatives through which would be possible to: I) reuse the residue inside or outside the processing plant, or, II) produce byproducts with aggregated value. The project proposed to develop support technologies to the açaí agroindustrial complex, w ... Status: Completed Start date: Tue Apr 01 00:00:00 GMT-03:00 2008 |

| The Lower Tocantins region, PA, presents agricultural traits that integrate both traditional and modern practices; the small farming's main activities are concentrated on yuca cultivation and flour processing. In the county of Moju, the productivity obtained by the great majority of small farmers oscillates between 9 and 16 tons/hectare, once great part of them do not select propagation material, do not control weed growth and don't cultivate using adequate spacing. Moreover, other common farmin Status: Completed Start date: Wed Apr 01 00:00:00 GMT-03:00 2009 |
| Grassland intensification strategies such as fertilization and irrigation can be used to shorten the period required for recovery of paddocks under rotational management and thus to increase the productivity. In rotational stocking grazing, the definition of the resting and grazing periods of the paddocks, besides determining the total number of paddocks, exerts a great influence on the quantity and quality of the forage produced. The post-grazing residue, determined by the grazing period and th Status: Completed Start date: Sat Sep 01 00:00:00 GMT-03:00 2007 |
