Buku KomposThis article about managing organic waste is a different with articel which I have previously written (Managing Organic Waste in Bunderan Traditional Market, Sragen-Indonesia). This method of managing organic waste is more simple and better than the previous method.

Organic waste from traditional markets, have slightly different characteristics with waste from housing. The composition of the waste from traditional markets are more dominated by organic waste. Plastic trash fewer than plastic waste from the housing. Moreover, if the waste came from the vegetable market or a fruit market, the organic waste will be more. I think this article is more suitable for the waste from traditional markets, more specifically the waste from vegetable and fruit market. This article based on real experience. Processed organic waste into compost and organic fertilizer granules.

Composting Organic Waste from Traditional Market

Processing organic waste from traditional market into compost and organic fertilizer is one of the alternative waste treatment that easier, cheaper, and faster. Composting method used is windrow system. Compost made in the windrow and covered with plastic.

Compostint Area

Ideally in each market should be provided land or area for waste processing. Required area adapted to the production of waste in this market. Small traditional markets are require approximately 1000 – 5000 m2. Place of composting can be placed on the back side somewhat hidden and far from the settlement residents.

Advantages of processing organic waste in or near the market :
1.reduce the volume of waste taken to landfill
2.save transportation costs
3.reduce odor and waste pollution
4.open job opportunities in the market
5.increase the added value waste into organic fertilizer.

Equipment and Materials Needed

This method is very simple, so do not require much equipment. Equipment required are:
1.plastic mulch to cover the compost pile
2.spade fork to sort out the waste
3.wastebasket
4.bucket
5.sack
6. plastic rope
7. wheelie bin
8. shovel
9. and other helper equipment.

To speed up the process of composting is used composting activators.

Separating waste was the most complicated in this process. Suppose the traders want and provided a place for waste sorting, this sorting process will be much easier and faster. The trash is separated from the other trash that can not be composted or difficult to composted. For example: plastic, metal, and others. Lumber or wood is also separated, because it need more time for composting. This lumber can be used as firewood.

Arrangement waste in pile/windrow.

Waste in the stacking layer by layer. In each layer of compost activators added. Rubbish markets generally have a high water content, so do not add water. Dilution activators using dry soil or sand. Activators be sprinkled evenly over the layer of garbage. Higher layer approximately 15 cm. High pile approximately 1 to 1.5 m. After a 1.5 m high pile, the pile covered with plastic mulch. Give assembly on mulch to keep flying in the wind.

Piles of rubbish were observed each week to see the composting processes. If there are problems in the composting process immediately solved. For example: the compost is too wet or too dry.

Composting process took place within 1 to 2 months. 1.5 months is usually sufficient. If the compost has matured, the compost immediately dried in the sun to dry.

The tools needed to make organic fertilizer granules from the compost include:
1. Chopper (if required)
2. sieve
3. Pan granulator
4. Scales
5. Sack sewing machine
6. Dryer (if required)

Add-on materials for the manufacture of organic fertilizers, such as:
1. Agricultural lime,
