1. Agroindustry Residues as a Source for Cellulose Nanofibers Production
Our study was motivated by the large amount of crop residues produced in Brazil, which represent underutilized waste biomass and a serious threat to the environment because of the landfilling. For example, even though the corn crop is not popular in Brazil, it is produced in the area of around 18-20 million hectares with an average production of 5-6 t ha-1.

2. Production and Characterization of the Bio-Oil Obtained by the Fast Pyrolysis of Spent Coffee Grounds of the Soluble Coffee Industry
Agro-industrial wastes are abundant and low-cost sources of energy and chemicals. Biomass account for 14% of the world’s energy production. Industrial residues of production of soluble coffee (spent coffee grounds - SCG) have great potential due to its large-scale production and can be transformed by pyrolysis, in liquid, solid and gaseous products with ap

3. THE FUNGAL ABILITY FOR BIOBLEACHING/BIOPULPING/BIOREMEDIATION OF LIGNIN-LIKE COMPOUNDS OF AGRO-INDUSTRIAL RAW MATERIAL
Lignin is present in plant cell secondary wall, associated to carbohydrates preventing their efficient hydrolysis, and cellulose pulp manufacture basically consists in breaking down the middle lamella of plant cells, individualizing fibers such as cellulose from the other biopolymers. Different levels of lignocellulose are found in plant residues and they ca

4. The use of geo-technologies to evaluate the potentiality of hydro-degradation in superficial waters by agro-chemicals : case of Antas River watershed, Bueno Brandão, MG / Utilização de geotecnologias para a avaliação do potencial de degradação hidrica das aguas superficiais por agroquimicos : caso da sub-bacia do Rio das Antas, Bueno Brandão, MG
In the county of Bueno Brandão, South of MG, the Antas River Watershed is located before the water supply area and is susceptible to hydro-degradation due to the damaging agricultural activities-chemicals was evaluated by the use of geotechnologies. The potato cropping is a remarkable activity among them due to the following features: intensive use of agro-

6. Desenvolvimento de uma metodologia analítica com microextração líquido-líquido para determinação de agroquímicos organofosforados em água
Many organic agro-chemicals residues are presented in low concentrations waters. Due to this, has been increasing the interest on the development of sample preparation techniques that give the possibility of analits pre concentration present in the matrix to adjust in the detection system. In this work, was used analytical method, the liquid-liquid microextr

7. Qualidade de goiabas ensacadas e manejadas com diferentes produtos fitossanitários, sob manejo orgânico / Quality of guava packed and managed using different phytosanitary products under organic management
Guava fruit culture presents serious phytosanitary problems usually controlled by the intensive use of chemicals, many of which have not been approved for this purpose. The growing and indiscriminate use of agro chemicals has put the health of consumers and farmers at risk, besides causing serious environmental problems. Faced by these facts, consumers have
