Stonbo Creative is committed to developing a self-sufficient circular ecosystem, advocating for the exploration of nature's inherent strength, and using black soldier flies to help solve the problem of organic waste, which can be used as feed and fertilizer or biodiesel to increase food and energy self-sufficiency.
Stonbo Creative operates a B&B and ecological farm in Toucheng, Yilan, producing a variety of vegetables and fruits, raising egg-laying hens, broiler chickens, bees and Taiwan tilapia. It has obtained an organic certification and provides natural and organic ingredients for the B&B, striving to achieve a self-sufficient circular ecosystem.
The multiple values of black soldier flies
The person in charge of Stonbo Creative is a retired professor of the Department of Entomology. His journey of research and development began in 2012 after he came across black soldier flies in the kitchen waste of the B&B. Black soldier flies can effectively process food waste, fruit and vegetable residues, and farm waste. The larvae can be used as feed for chickens and fish, and the insect excrement can be used as organic fertilizer, forming a zero-waste closed circular system.
Automated feeding system
Raising black soldier flies requires a lot of human resources and space. Stonbo Creative has developed an automated feeding system that can automatically supply food and adjust the feeding temperature to improve eating efficiency. This system has been granted patents in many countries. After the company gained valuable experience with this system, Stonbo Creative began to promote the automated feeding system of black soldier flies for the treatment of various organic wastes. Waste is divided into three categories depending on its nature:
- Food grade waste: It includes kitchen waste, soy pulp, and distiller's grains, which are used as feed after being used for raising black soldier flies, and insect excrement is used as fertilizer.
- Animal manure: Once black soldier flies reach maturity, biodiesel is extracted and the insect excrement is used as fertilizer.
- Sludge or digestate: The treated black soldier flies can be used to extract biodiesel or the insect excrement can be used as biomass energy.
Benefits
- Using black soldier flies to treat approximately 30 million metric tons of organic waste produced in Taiwan every year can reduce greenhouse gas emissions and lower the risk of spreading public health diseases.
- Black soldier flies can further be recycled as feed, fertilizer or biodiesel to improve food and energy self-sufficiency and create a circular ecosystem.
