This review article addresses the use of biological activated carbon in water treatment and its techniques for its development, with the premise of analyzing the potential of Activated Carbon (AC) in the treatment of water for human consumption. For this end, it aims to identify the techniques used for the production of AC, use and its benefits, production from vegetable waste for water treatment. Activated carbon has the ability to selectively collect gases, liquids and impurities inside its pores, which is the reason it is widely used in filtration systems and for that the treatment of water, the coal fulfills the function of adsorbent, retaining in its pores certain types of impurities: large particles that cause undesirable color, taste or odor in the water. In the treatment of effluents, coal is used for clarification, deodorization and purification of effluents.

The process of industrial restructuring has adopted different types of relationships in order to guarantee the organizations survival and development. Bioindustry requires high technical-scientific investments that are obtained through partnerships. These collaborative relationships, however, have been challenging in Brazil. In the Amazon context, where value adding in the use of biodiversity resources bears high importance for regional sustainable development, studies point to difficulties of interaction between bioindustry firms, university, and government. Against this backdrop, this research analyzes the perception of entrepreneurs operating in the Amazon bioindustry regarding the inter-organizational relationships. Qualitative research was carried out with thirteen firms, collecting data based on network pictures, complemented with semi-structured interviews. The study identified that attributes such as friendship and trust are primary factors in the relationships, and that the complementarity of resources is the main reason to establish partnerships. However, the findings suggest that inter and intra-sectorial relationships in this Amazon bioindustry are far behind what is recommended in literature to affirm the existence of a business network. Therefore, the study points out the need for strategic actions to approximate these actors in bioindustry.
