Ask the head of Palmerah market, Pence Harahap, about the composting pilot project introduced by local subdistrict officials several months ago, and his first response is to laugh.
"The (composting) machine can manually process only about one cubic meter (of waste), while the market produces 17 cubic meters each day. Using it would be a waste of time and energy," the market head said Monday.
There is nothing wrong with the initiative at Palmerah market.
That is, apart from the fact that its scale fails to match the amount of waste the market actually produces.
And the apathy of the market's operators is also contributing to the program's failure.
"Bantar Gebang (Jakarta's final dump in Bekasi) can still accommodate the city's waste. So why bother?" Pence said.
"The garbage men don't have time to manually chop a small amount of our waste for composting."
For Pence, the subdistrict level initiative to reduce organic waste from his market is both impractical and unnecessary.
In the Senen wet market, a composting machine which has been installed for several months only operates weekly, local vendors said.
"The garbage collector more often dumps the waste straight onto the trucks. As far as I know, the machine is rarely used," said Hamdani, owner of a stall near the market's dump.
Senen's composting machine can supposedly process up to 3 cubic meters of organic waste, or around a quarter of the market's 12 cubic meter total.
The operators of Senen market refused to comment on the stalled progress of the composting project.
But it seems that the root of the problem is similar to the failure at Palmerah.
The composting of organic waste in the city's traditional markets was introduced in 1997.
Supported by the non-governmental organization the Kirai Foundation, the Bintaro market authority assigned two officers to sort out and compost organic waste, reducing total waste by almost 30 percent while providing extra income for local vendors.
But replication of the project was not done until recently, following the growth of community-initiated waste management projects.
Municipalities are now targeting traditional markets, which produce up to 10 percent of the city's 25,000 cubic meters of daily waste.
Since most of the waste produced by the markets is organic, composting appears to be a feasible option, both economically and environmentally.
If done properly, that is.
"There were no surveys before they placed the small composting machine here. That was why the one installed has failed to match the scale of our waste production," the Palmerah market's Pence said.
A different example of how composting could work can be found in three wet markets in North Jakarta.
North Jakarta municipality introduced its pilot project at the Sindang market, the Koja market and the Sukapura market last month.
Each market installed composting machines of varying sizes, costing between Rp 4 million to Rp 8 million.
The composting project is managed by the local traders' cooperative, which supervises the process and is entitled to sell the fertilizers produced by the composting process.
The Koja market has produced around 100 sacks of fertilizer this week alone, local market officer Sugiyono said.
