Gremix: Sustainable Cement
Concrete is the most widely used artificial material in the world. Unfortunately, cement - the essential ingredient that binds concrete together - is responsible for 8% of global CO2 emissions. With over 90% of cement produced in developing countries, and demand expected to surge due to urbanization, solutions to lower emissions that come with a green premium are likely impractical. In response, Team Gremix aims to develop a cost-effective and scalable solution to reduce cement emissions. To start, the team is focused on sourcing fly-ash, a byproduct of coal combustion, from landfills to replace up to 40% of cement in concrete production.
Oleo: Sustainable Palm Oil
Palm oil is the most widely-used vegetable oil in the world. Its production begins with clearing tropical rainforests. To address this issue the team is working to develop a synthetic palm oil alternative produced from repurposed oil palm waste streams to benefit smallholder farms in Indonesia and keep economic development within the country while also reducing the demand for farmland and the clearing of rainforests.
Methane to Aquaculture Feed
Producing methanotrophic protein from landfill gas is a promising technical solution for directly reducing greenhouse gas emissions in developing economies. The team plans to develop and pilot a system in Bangladesh. Their approach uses low-cost methane feedstock and supports a new industry that would provide employment and tap into local markets. Bangladesh is one of the fastest growing economies in the world with a growing demand for animal feed to support its local aquaculture industry.
