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.

3. Sugarcane bagasse ash: new filler to natural rubber composite
Waste recycling has been the subject of numerous scientific researches regarding the environmental care. This paper reports the redirecting of sugarcane bagasse ash (SBA) as new filler to natural rubber (NR/SBA). The NR/SBA composites were prepared using an opened cylinder mixer to incorporate the vulcanization agents and different proportions of residue (SB

4. New cultive medium for bioconversion of C5 fraction from sugarcane bagasse using rice bran extract
The use of hemicellulosic hydrolysates in bioprocesses requires supplementation as to ensure the best fermentative performance of microorganisms. However, in light of conflicting data in the literature, it is necessary to establish an inexpensive and applicable medium for the development of bioprocesses. This paper evaluates the fermentative performance of S

5. Removal of diuron and hexazinone from guarany aquifer groundwater
The economy of many communities in southeastern Brazil is based on agroindustry, particularly the sugarcane industry. Recent studies have found increased use of herbicides in this type of agriculture, among which diuron and hexazinone are the most widely used. The water supply for some communities is derived entirely from the Guarany Aquifer (the world's lar
