Dutch designer Judith Zeeman has created a series of objects out of biochar (charcoal made from agricultural waste) to raise awareness about the environmental benefits of the material. We were particularly impressed by the clock. She mixed together starch, water and biochar to mold three clocks that are all symbolic of the Carbon Age. Each one represents the three stages of the carbon age in how the carbonaceous gases has effected the world today: the black powder period, the coal period and the oil period. The clock’s pointers exemplify the rate of carbon emissions sent out into the atmosphere each year (The hour hand represents coal and the minute hand represents oil). These clocks were also made to help slow down the Greenhouse Effect. By burying them in the soil, they effectively reduce the amount of carbon dioxide in the air.
