Food loss/waste has significant economic and environmental implications, as well as social repercussions (fighting hunger) when so much food supply is wasted between farm and table. Consequently, I always enjoy learning about new, innovative food-waste (a.k.a. garbage) diversion concepts. Time for an update.
Food waste (a.k.a. garbage) diversion is a novel sustainable approach converting what is normally considered waste in either the beginning (production) or end (consumption) of the food value chain into palatable food products. Recently, I learned about an innovative waste solution, a potential game changer for sustainable aquaculture. Fact: Due to fish consumption being at an all time high, a third of the world’s oceans is over fished (source: Food and Agriculture Organization of the United Nations), thus raising a red flag for the future sustainability of a key protein for millions of people worldwide. One viable solution is aquaculture (a.k.a. fish farming), the fastest agricultural sector for the past forty years. However, critics of aquaculture are concern about farm fish feces contaminating oceans, lakes and drinking water, plus the drain on environmental resources (e.g., corn, soy, ground fish, etc.) needed to feed farm raised fish.
Enter TimberFish Technologies originally launched in 2008. They feed their fish with a combination of nutrient-rich wastewater from food processors (breweries, distilleries and wineries) and wood chips. Wood chips contain microbes, a source of food for small invertebrates like worms and snails. The fish eat the invertebrates. Two additional sustainable benefits of their innovative technology: 1.) The fish excrement provides a source of nutrients for the microbes completing a cycle; and 2.) TimberFish Technologies system’s only output is clean water plus spent wood chips further utilized as a biofuel or soil supplement.
