Comparison ( ratio ) C / N for an effective composting process ranged from 30 : 1 to 40: 1. Microbes break down compound C ( Carbon) as an energy source and use of N for protein synthesis . At C / N ratio between 30 s / d 40 C for microbes to get enough energy and N for protein synthesis . Conversely , if the C / N ratio is too high , will the lack of N for microbial protein synthesis so that decomposition is slow. Organic ( Bulking Agent) Green Phoskko® ( GP-2) is a mixture of minerals , energy and nutrient enrichment - which serves as a starter in the preparation of raw materials ( organic materials ) to ongoing decomposition of waste into compost. Green Phoskko® ( GP-2) ability to raise the temperature mesophilic phase , neutralizing the pH , enrich the content of compost , improve the porosity of waste materials , and facilitate penggemburan / decomposition of organic waste in sewage treatment process . Bulking Agent is composed of bran , sawdust fines ( dustwood ) , zeolite , aditive , dolomite and other minerals with a specific composition . Use bulking ( bulking agent ) to taste ( can be used as a standard 30 kg for 3 m3 of waste ) when ready to be processed waste decomposition . Mix until evenly into the garbage bin which affected every part of this bulking powders . With more and more uneven and inadequate, the faster the decomposition process , content and free from odor . Green Phoskko® ( GP-2) safe to hold hands / exposed skin.
