Biophosko® composter [ S] with dimension ( Height= 60 cm, Diameter= 35 cm) , a drum as compost bin made of plastic is the right solutions to handle trash ( especially for organic trash from households remnants such as : food, papper, etc) . Transform the households trash into something useful like compost which is benefit to preserve the fertile of the soil and also as the nutrients supplier for your plants. Composter Type S capacity is 0, 04 m3 or 15 kg organic trashes ( density 200 kg/ m3) . Composter Type S has the capability to process trashes up to 5 day households garbage. Each person in Indonesian households produce trashes about 2, 6 litre each day or 15 litre each family in Indonesia households with 5 member/ family. In order to processing organic trashes using Composter ( Type S) , follow the procedure bellow:
______________________________
First, prepare household' s organic trashes ( food remnants, vegetables, fruit peel, fish, and meet) and also make sure the trashes materials has been chopped into small pieces ( 10-50 mm or 5 cm) . Capacity of Composter ( Type S) , dimensions with Height x Diameter ( 60 cm and 35 cm) is + / - 0, 04 m3 ( cubic) or equal to 15 kg organic trashes ( convertion or density/ cm3 of trashes weight to volume is 20% ) . For household domestic trashes or restaurant, its not difficult to make/ cut the trashes into small pieces. Beside the households trashes is already in small size, to mince ( cut into small pieces) the household organic trashes wont do any trouble because the small amount of the trashes, to mince, its enough to slice it up using knives or other kind of slicing tolls.
_____________________________
Second, put the organic trashes into mixing container like bucket, pail, or other kind of container. Mixed with Green Phoskko® Bulking Agent 1-3% from the materials or equal with 0.5 kg for 15 kg organic trashes ( for Composter Type S) , and stir it flat. The usage of bulking agent is depends on the compost material' s condition ( organic trashes) , which is, if the material got too wet, bulking agent usage ratio is 3% , and if the material got too dry, bulking agent usage ratio is 1% from the amount of the organic trashes. However, the more usage of bulking agent to compost materials ratio, the better of the decomposition process and the nutrients within the compost.
______________________________
Third, when the absorption of bulking agent into the compost material occurs, in different container; prepare the Green Phoskko® Compost - Activator. 5 spoons of compost activator microba- if available add in 1 spoon sugar or 1 spoon molases ( sugarcane) and dissolve it within 10 - 15 litre of water. Stir flat, and the microba is ready to flush onto the trashes materials- which has been mixed with bulking agent ( right on the second step) slowly, a little by a little ( partially) or keep it first for 2-4 hours would do much better.
_____________________________
Forth, when its feel the microba and the water has dissolved well into the materials ( identify by the trashes, when you lifted up the materials, the water wont drop from the materials, but when the materials got swueeze the water will drop) , put the compost materials into Composter. Within few days later the heat reaction will occur, the temperature within the drum up to 70 degree celcius, if available you could measure it using the thermometer. When the heat reaction occur, make sure do not remove the cover from the drum so that the perfect decomposition will achieve.
_______________________________
Fifth, at days 5-6, decomposition reaction inside the Composter will through, and by that time another organic trashes might added in ( the material preparation according to step 1 -3 above) . Or, if it' s feel necessary, at days 7 - 9, if the temperature below 30 degree C or considered cool, the composts is ready to harvest from the bottom part inside the Composter thru the door that lies at the bottom side of the drum. The Material composts is still wet, sticky, and moist, that compost condition require to keep on a cool places and covered by the sack to wind it up. Wihtin a few days later ( generally in 3-5 days) the wet compost materials will dried up and loose. Then, if the composts goes to sells commercially, sieve the compost material so that will separated the big and the small composts granule. The big granule composts actually could be pounded into small pieces or reuse for your plants. Put the composts small granule into the package sack as its planned. Then now you have composts that made by your self which is ready to sells or to use for your own plants.
