Graphene-Modified EPS Modular Stores Give Small Farmers Affordable Potato Storage

Chinese researchers have developed modular, prefabricated storage units made from graphene-modified expanded polystyrene (EPS) for small farmers who lack the capital to build permanent storage facilities. A single module covering 28 square metres can hold up to 18 tonnes of potatoes and can be assembled in just a few days, making it a practical option for operations with limited budgets, land, or construction capacity. The design relies on natural cold to maintain favourable conditions inside the store, avoiding the energy costs and complexity associated with refrigerated warehouses.
