The bulk of municipal waste is biodegradable organic matter ( 60-75% ) coming from the kitchen and yard. This kind of waste if allowed or too late will be processed in anaerobic odor due process alter sulfate into sulfide. Chemically, this process is reacting lactate into acetate sulfate, sulfide, water, and CO2. Sulfide ion reacts with H + and Fe2 + to H2S and FeS form of foul-smelling black liquid.

Management of urban waste is to be eradicated, not only require large-scale waste processing technique that capital intensive, but also simultaneously require the application of small-scale waste processing technique which is distributed in large numbers so as to reduce the burden of centralized waste, and become an important means of maintaining cultural practices cultivate waste independently, which will be the basis of ecosystem resilience at large-scale unit to crash.

The completeness of the production of compost using Biophoskko® Rotary Klin for communal scale ( several RT, housing blocks, RW, markets, hotels, factories and commercial areas) has become more advanced and modern. Machine- making materials made of metal circuits, fiber resin, exhaust fan, and Reducer. Likewise, supporters and supporting equipment such as machine work counter trash ( Chopper) , compost sieve, packing sealer and conveyor belt ( filter and an organic) was developed in part modernize sewage treatment becomes more efficient and faster.

With the engine pushing the Rotary Kiln is also the birth of business Cleaning Services ( outdoor Cleaning Service) - for example housing complex ( Real Estate) , apartments and offices. Because of the garbage from their own environment, resistance ( resistance) community about the processing of waste at source ( IPKK model) is lower compared to the scale sewage treatment project of the city - which for example is concentrated in one location, as a TPAS ( The End of Waste Disposal) .

IPKK engine package adequate for the management of over 1 ton or 3 m3 of waste / day, or manage waste from approximately 200 houses ( 1000 people) a continuous non- stop every day. This package will make a small business IPKK in producing 400 kg of compost ( 40% of the weight of waste) and 20 to 25 bottles of 500 ml of liquid organic fertilizer ( 1 per mile from the weight of waste) - every day.
