REIMAGINING THE WASTE FLUX OF JAKARTA —RESILIENCE BEHIND THE WASTE HIERARCHY OF METROPOLIS

Zhou Zuyuan

Narrative:

The project is located in West Jakarta. After assessing the current situation, the issues I summarized are as follows:

-Insufficient waste collection frequency

-Environmental issues caused by insufficient solid waste treatment

-The mixture of waste from the source

-Limited space for temporary waste storage points

-incomplete solid waste treatment system in neighborhood site(mainly collection system)

However, beyond the problems mentioned above, the site still has great potential. In the first place, 65% of the waste generated is organic. if organic waste is treated effectively, the amount of solid waste transferred to the landfill can be largely reduced. In addition, a large amount of underutilized green land in the neighborhood site. Most of them are now used as temporary storage for solid waste. If these green spaces are upgraded and used effectively, their potential will be greatly stimulated.

The project with the vision to treat the waste from the source and tackle the waste problems from the source. Targeting the issues identified, the strategies are set up:

-Waste separation from the source.

-Utilize the underutilized green space for centralized composting facilities.

-Neighborhood-based composting

The above steps build a new garbage system comprised of several decentralized composting facilities as well as micro compost units scatted in the neighborhood.

System:

-Micro-level compost system(Little composting system contains waste separation, collection, composting and recycling, implement in the RT boundary)

-Centralized composting facilities (Large composting system with 3 categories facilities: small size facility, medium-size facility, large size facility. The facilities are categorized according to the size of the facilities and the equipment they have.)

Through a rough estimation, if we assume that the centralized system has 50 large facilities, medium-sized facilities are small size facilities. And in the micro-scale, each unit can cover one RT, the system can process 50% of total waste and 85% of organic waste. In this way, the amount of waste transferred to the landfill can be largely reduced, the status of solid waste will be effectively alleviated.

The ongoing consequences of waste will continue to impact the life of the local people in ways that cannot be ameliorated or erased. The proposed system can be connected to several functions that may engage the public with landscapes of waste as a way to reveal the unconfined impacts of the waste system to improve the living environment and increase economic benefits.

Existing Cycle Of Solid Waste

Existing Solid waste flow in Jakarta

Existing collection system

Collection source

Collected by agencies, directly transfered to the landfill. (E.g. Market Agency, Public Works Agency, Cleansing Agency or private means.)

Storing waste in waste bin, plastic bag or cardboard boxes in front of the house. The solid waste is collected by wagons or trucks, and transfered to a temporary disposal site area before transport to the landfill afterwards.

Transportation

From temporary disposal sites (or from solid waste generators for the direct system), collected waste is disposed of in the landfill located at Bantar Gebang. The types of vehicles are usually wagons and trucks.
