What challenge does address?Our community partner, Carolina for Kibera (CFK), runs a programcalled Taka ni Pato (Trash is Cash.) Local youth groups collect mixedsolid waste from households for a small fee per bag.CFK then helps the youth to sort the waste and sell the plastic, paper,glass and metal recyclables to brokers. Organics, which make upover 70% of the total, are currently discarded. mixed organic > 70% of total

The densely-populated communities sufferfrom serious air pollution.
farms100 kg Black Soldier Flies (BSF)*, which convert organic waste to larval biomass.organic The larvae can be used directly as animalwaste feed or processed into a high-value protein meal. *BSF are common in Kenya and do not transmit diseases because the adults, having no mouth parts, do not feed.45 kg 18 kglarval proteinbiomass meal (about $30) Photos (left to right): http://organicfarmcostarica.wordpress.com, Christian Grantham via Flickr, http://lptechnologies.net, http://davesgarden.com
So we designed & prototyped our first System.A commercial BSF-farming system with passive-automatic harvest mechanism,temperaturecontrol & vertical modular design for optimal yield in tight urban spaces.Local entrepreneurs will operate GrubCycle franchises using these systems. We will supportmaintenance and business development, including sales of BSF to local farmers and animalfeed manufacturers.

Why does work?Every part of the process generates income: mixed organic CFK youth charge Each GrubCycle Factories sell a collection fees operator earns about competitive feed and sell sorted $8 /day by selling product. recyclables. mature BSF larvae. High demand for feed Avg wage (Kibera) is $1 /dayOpportunity to scale up Kenya generates 1.2 million tons of organic waste each year. We can convert this to a $350,000,000 market for larval protein meal, in Kenya alone.GrubCycle turns every 1 kg of organic waste into 29 cents worth ofprotein meal.
