KubeKo is an integrated waste management approach that introduces green chemistry to generate value from excess biomass and includes a smart micro-grid to distribute the biogas and electricity.
With the KubeKo system, the aim is to introduce financially viable off-grid biowaste management to produce and distribute energy and fertiliser to local businesses and households. This is done by combining the best available technologies, biological conversion of biowaste and careful market segmentation to provide high value services. The technological approach relies on well established biological treatment for wastewater and sludge namely Anaerobic Baffled Reactors (ABR) to hydrolyse and perform the acidogenesis and acetogenesis phases and Upflow Anaerobic Sludge Bed (UASB) Reactors for high rate methanation to produce the biogas. The units generate clean gas, electricity and a nutrient rich liquid digestate. The units are sized for three classes, namely: agroindustry, businesses (hotels, restaurants), and communities. The dimensions proposed are 20, 100, and 250 m3 total digestion volume to produce electricity and biogas. For all three classes, the digestate is concentrated using micro membrane systems and conditioned for distribution to local agricultural cooperatives.
- •Purification of the digestate to produce fertilizer for local use.
- •Reduction of greenhouse gas emissions by over 80% by eliminating uncontrolled CH4 emissions.
- •A reduction of 20% in the cost of mineral fertilizer for crops.
