Biobased Battle 2021 - Outubro

The Biobased Battle is a model for an educational development. During the battle, Dutch and Brazilian students with different backgrounds work together to solve environmental issues from the industrial sector. Throughout the week, the teams receive an assignment, and must build innovative solutions rooted in biobased economy concepts. The battle ensures that students must quickly tackle a complex issue, and that they work together with students with different backgrounds. This ensures that students learn to recognize each other's field of expertise and use it to achieve valuable results at the end of the week.
The Biobased Battle is a product of Living Lab Biobased Brazil, hosted by Universidade Federal de Ouro Preto (UFOP) and Avans University of Applied Sciences. This program is organized in cooperation with the Centre of Expertise Biobased Economy (Breda, the Netherlands).

The circular economy concept emphasizes the need to minimize the usage of fresh resources via the 3R strategies: reduce, reuse, and recycle. Usage of water in domestic and industrial activities contributes to more than 44% of the total consumption in Brazil (FAO, 2016). Typically, any process that uses water will generate wastewater. As the wastewater can be regenerated for subsequent reuse, a resource recovery step can be conducted simultaneously to recover or extract any valuable elements or compounds in it. These processes can be anaerobic and aerobic, and the recovered compounds can include, for example: cellulose, biogas, phosphorus, nitrogen, heavy metals, and bioplastics.
Anaerobic digestion has been widely used as a biobased conversion technology to digest the excess residual streams, in which hydrogen (H2) and methane (CH4) are the main biogas products that can be recovered. CH4 is used in various industries such as automotive, chemical, electrical, and aerospace due to its applications as fuel, natural gas, liquefied natural gas, liquid methane rocket fuel, and raw material in chemical industries. On the other hand, H2 also has a variety of applications, for example, in metal processing, glass industry, edible fats and oils, energy, and others.
This year, the challenge is to think of different single or combined processes of wastewater recovery to maximize the recuperation of products depending on residual composition and scale (i.e.: small to large population equivalent). The groups can choose from: domestic sewage, pulp and paper effluent, and/or brewery wastewater.
