The document describes a program by Carolina for Kibera (CFK) that addresses waste management in Kibera, where local youth collect and sort waste, and organic waste is largely discarded. It introduces a BSF farming system to convert organic waste into larval biomass for animal feed, aiming to generate income for local entrepreneurs and reduce pollution. The initiative targets a large market opportunity in Kenya, with the potential to convert significant organic waste into a profitable product.

- 1. What challenge does address? Our community partner, Carolina for Kibera (CFK), runs a program called Taka ni Pato (Trash is Cash.) Local youth groups collect mixed solid 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 up over 70% of the total, are currently discarded. mixed organic > 70% of total
- 2. Photo: http://media.disciplesupport.org Inadequately managed organic waste in the largest African slum, Kibera in Nairobi, contaminates water supplies and attracts disease vectors. With no other options, Kibera residents frequently burn organic waste. The densely- populated communities suffer from serious air pollution.
- 3. farms 100 kg Black Soldier Flies (BSF)*, which convert organic waste to larval biomass. organic The larvae can be used directly as animal waste 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 kg larval protein biomass meal (about $30) Photos (left to right): http://organicfarmcostarica.wordpress.com, Christian Grantham via Flickr, http://lptechnologies.net, http://davesgarden.com
- 4. So we designed & prototyped our first System. A commercial BSF-farming system with passive-automatic harvest mechanism,temperature control & vertical modular design for optimal yield in tight urban spaces. Local entrepreneurs will operate GrubCycle franchises using these systems. We will support maintenance and business development, including sales of BSF to local farmers and animal feed manufacturers.

- 6. 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 /day Opportunity 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 of protein meal.
