Bio Methanation of MSW & Biodegradable Wastes : A Sustainable Green Future
STEELITE Group’s Green Energy Division (GED) & and its associates have developed NPB (Natural Power Balance) microbial technology (Patent Pending) to treat and process mixed municipal solid waste. Our expertise is in converting mixed MSW into fuel (Biomass and Refused Derived Fuel) that can also be utilised for power generation
We have expertise in Modified UASB (Upflow Anaerobic Sludge Blanket) Technology for High Rate Bio-Methanation (HRBM) of organic waste. Our biogas technology (gas generation, gas cleaning & gas bottling) consumes least energy per cubic meter of biogas generated and enriched
The combination of NPB & HRBM technologies can make the MSW project sustainable and financially viable by delivering multiple marketable end-products, such as Biomass, Refused Derived Fuel (RDF), Biogas, recyclables and high quality compost. All Types of green (biodegradable) waste can be utilized for biogas generation
Salient Features of MUASB Technology
The main difference between a regular UASB reactor and the MUASB digester is the acceptance of biodegradable solid contents along with liquids in the range of 0.1% to as high as 10%. The digester can be constructed in a variety of ways with a floating dome or with fixed dome with separate balloon storage. It is capable of taking multiple feed stocks with high SRT. Because of high SRT, the most of the influent solids are digested within the reactor and converted into biogas.
Capable of handling multiple feedstock
Single Digester in place of two digesters
High solid retention time and low Hydraulic retention time i.e. Planned slurry tapping for manure management
Water saving by partial recycling and use as liquid manure by drip or spraying
Minimum 10% of the total feedstock should be cow-dung. This stabilizes the fermentation process irrespective of seasonal variation of other feedstock.
For monitoring of regular pH levels etc. simple procedures can be adopted instead of instrumentation.
The high SRT and low HRT provision allows the digester to perform well at even lower temperatures, eliminating the need for feed heating system or internal heating system.
