Enhanced rock weathering supply chain life cycle sustainability

Eunice Oppon

The project

Research has found that speeding up the naturally occurring process of the weathering of rock to draw CO2 out of the atmosphere could help to significantly stabilise the climate and avert ocean acidification caused by humans burning fossil fuels. This is referred to as ‘enhanced rock weathering’.

The supply chain of the enhanced weathering process will require the mining, comminution, transportation and application of these silicate rocks in targeted areas to result in significant draw-down in CO2. My research looks into ensuring sustainability of the process by measuring the economic, environmental and social impacts.

Along with her fellow Grantham Scholar Jonas, Eunice worked on a Defra funded project about food waste. As part of this, she and Jonas came up with a new approach that considers both the social impact of the food redistribution and the resource value of food.

Grantham Scholars – Jonas CromwellGloria MensahYe Jiang, and Eunice Oppon – went to Anne Grove Primary School. Their aim? To try help reduce food waste in schools. Look here for the blog they wrote about their work.
