Pour cette édition #OH149 nos invités présenteront Trobak. Ce système est le premier compost connecté sans odeur qui vous permettra de « fermer la boucle » : vous jetez vos déchets alimentaires, vous attendez que notre dispositif réalise son travail et vous récupérez votre compost après 3 semaines !
Ce projet étudiant est réalisé dans le cadre du mineur CHIC qui réunit des étudiants venant d’horizons divers. Cette équipe pluridisciplinaire est composée d'étudiants EPFL, ECAL et HEC. A bientôt pour cette découverte écologique!​

For this #OH149 our guests will present Trobak. This system is the first connected smell-free compost which will allow you to "close the loop": You throw your food wastes, you wait while the device does its job and 3 weeks after you gather your fresh compost.
This student projet is realised as a CHIC program minor gathering students from different background. This pluridisciplinar team is composed of EPFL, ECAL and HEC students. See you soon for this eco-friendly discovery.

ABOUT OUR PROJECT:

I'm Pierre, student in Master (Mechanical Engineering) at EPFL. I'm working on Trobak for my minor CHIC (China Hardware Innovation Camp). It is an amazing initiatives which gather students from ECAL (industrial design, media-interaction design), HEC (communication system) and EPFL (Mechanical and Micro-technical engineering). The first purpose of this project is to LEARN. We are building a connected compost (IoT) that could achieve a semi-mature compost within three weeks. Our team is divided into four main parts: our values (logo design, customer segments etc.), our design (artist avec mechanical points of view), our connected aspect (PCB design with sensors) and the bio-tech part (make semi-mature compost in three weeks). We have join Hackuarium for this last topic, as we need more practicals competencies on this field!

OUR DEVELOPMENT:

At the beginning, we've worked a lot on the different possibilities offered to us. We considered lombricompost, bokashi compost, and "additive compost" (adding bacterias, yeasts to accelerate the process, such as the Sera (Whirlpool) compost). We've done a large survey to know if people would not be disgusted to have a lombricompost at home. The major part said that they would not like it. But, if they don't see worms, touch them or manipulate them, a large part would consider trying our dispositive. As we have seen that it could be really difficult to certify these previous remarks, we have chosen to work on a bokashi/additive compost.
