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

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 ...

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
