After an insightful morning at Potrero Grande, we had the opportunity to discuss the project in depth with the organisers during a one-to-one. During the afternoon we parted ways. Two members of the team joined our fellow decathletes for tour of Cali to see the sites, experience local delicacies and partake in some salsa. The remaining two attended a meeting with Emsirva, a company which developed a brick entirely made of sediments and construction wastes. This was extremely beneficial particularly in relation to mycelium. Many exciting ideas were explored!
