With apologies to those who might be reading this over their morning coffee or tea, today’s post collects three projects that follow the food chain all the way through the digestive system and out the other side.

Firstly, over at we make money not art, Regine has published a fantastically interesting post about Gilpin Family Whisky, including a short Q&A with its creator, design student James Gilpin. Using an initial donation from his diabetic grandmother, Gilpin has developed and refined a process to produce “high-end single malt whisky for export” from the sugar-rich urine of Britain’s elderly.

In urine-derived glucose, Gilpin identified a resource that is growing rapidly (populations of both Type 2 diabetics and elderly people are on the rise) and yet is completely underutilised —indeed, sugary piss is currently regarded as a nuisance, causing “unusual scale build up” in the bowl, not to mention “rapid mould growths.”

Meanwhile, notes Gilpin, “the whisky market is growing faster then any other alcoholic beverage worldwide.”

Gilpin’s breakthrough—the idea that sugar crystals extracted from old people’s pee could be fermented to produce alcohol—turns something that is generally regarded as a symptom of bodily failure into a positive enhancement.

In the light of Gilpin’s tongue-in-cheek vision of retrofitting every old people’s home with a DIY distillery in the garden, busily churning out high-value “biologically-enhanced whisky,” my own, normal blood sugar levels seem somewhat boring. This, of course, is exactly Gilpin’s point.

Meanwhile, in Chicago, activist gardener Nance Klehm took a slightly more traditional approach to creating value from the by-products of consumption. Klehm managed to persuade several fellow city dwellers to join her “urban nutrient recovery project,” collecting their shit and piss in a sawdust toilet and putting it out for pick-up once full. By the end of 2008, Klehm writes, “1,000 gallons of human nutrient was collected.”

These kinds of guerrilla, sewage-system hacks are — unsurprisingly — frowned upon by neighbours and city officials alike. As a result,  Klehm kept her stockpile of human excrement hidden “in an undisclosed storage area in Chicago” throughout 2009, as it composted into “black gold.” Her project recently culminated in “The Great Give Back,” as participants received their portion of the rich new soil, ready to feed balcony-grown tomato plants and community gardens across the city.

Finally, for the time-crunched and/or literal-minded, there is a short-cut method to transmute your excreta into something highly desirable. Ingest just a handful of designer Tobias Wong’s gorgeous pills filled with pure silver leaf, and, he promises, the metal will “pass straight through the body and end up in your stool — resulting in sparkly shit!”
