Macro utility definition
Macro utility means the capacity for aeration, batch drying, and fumigation can also be moved between locations. Quality is maintained and processing to bowls, bags, sacks or bulk is made easier by gravity. If for example maize yields are above average, it is cost effective to lease additional macro utility to store what will be sold first. When the macro lease(s) are empty of what is sold first, those lease payments end and mobile storage scales down to decreasing costs. On the other hand, if owner maize yields are so low that owner macro utility is available, then the bin(s) are a “mobile asset” (Growing Africa, 2013) that can be leased by owners to others for temporal or spatial arbitrage of for example paddy rice, animal feed or cassava chips.
