Poopook; Fecal Sludge and Organic Waste derived Fertilizer
Explain your idea in details:
In Indonesia 95% of fecal sludge is not treated properly, this is heavily polluted 70% rivers causing environment and health problem(World Bank, 2017). Most untreted fecal sludge is disposed to river or land-fill instead of returning its valuable nutrients and organic compounds to soils and for agricultural production. Whereas, farmers in rural area struggle to maintain yield production because soil nutrient insecurity and dependency on expensive imported fertilizer. Aside from its benefit to provided higher crop yields, intensive usage of mineral fertilizer also resulted in declined of soil fertility,water pollution,and decrease microbial activity. Poopook adress these problem with circular economy approach. Recovering nutrient and organic compounds from waste and convert it to safe rich nutrient fertilizer Recovering fecal sludge (FS) resulted valuable soil nutrients:1,200 tons N,170 tons P, 330 tons K from a city with 1 million residents per year (IWMI,2016).Although FS contains these beneficial resources, the raw sludge contains high pathogen concentrations. Co-composting fecal sludge and high carbon organic waste (food scrap, food waste, agriculture waste) enable it generate biologically produced heat (45-50oC) that allow development of thermophilic condition . This will properly sanitized and complete pathogen destruction. Waste pretreatment should be conducted prior co-composting such as dewatered FS with solid-liquid separation systems and organic waste sorting from hazardous material. After market research, co-composting technology will be decided between open systems or closed in vessel system.
Expected impact of your idea on sustainable development
First, in the big picture, it will provide safely managed sanitation services, not only access to the toilet but also affordable treatment. By providing this safe and affordable treatment of sanitation waste, we can mitigate water pollution caused by un-safe human waste disposal. Furthermore, we hope it will improve their health condition. Second, it creates new business opportunity in sanitation supply chain. Most of the business in this sector limited to provide access to toilet and emptying, transporting human waste. This project can extend the business opportunity to the treatment of this human waste, re-use and sale of treated waste. However, unlike other sectors, to create a scalable business, sanitation sector need endorsement and support from other organisation, especially the public sector.
Plans for implementation and sustainability
Poopook bussiness will focus on treatment and re-use of waste. Revenues come from two streams. First, from households, company, and the city for the treated waste volume. For Househould there is need for them to regularly collecting waste and emptying toilet, especially those who use On-Site Sanitation services such us septic tank services. In addition, for company and city there are regulation to treat their waste properly in order to meet environment and health standard. Second, from the sold fertilizer. Fertilizer will be marketed as safe, affordable, nutrient fertilizer. Target market for fertilizer sale are large bulk purchasers (flower businesses/horticulture, tree nurseries, real estate/landscaping and tree crop plantations) and Department of Agriculture and Department of Forestry under their extension service and subsidy for organic fertilizer usage.
I have a strong interest in circular economy, especially waste related issue. I am currently a student in Agriculture Science in Resources Management in Tropics and Subtropics. My field of research is Soil science , more specifically I study the effect of fertiliser derived from faecal sludge and organic waste on soil nutrient availability.
