Policy Report

The problem of solid waste management has nowadays arisen into critical issues in some big cities of Indonesia. Whole responsibility for the waste services is mostly carried by its local governments (LGs). The mixed waste is collected at household level, transported and disposed to the dumping site. As the result, it is threaten the lifetime of dumping site.

Surabaya city has been known as the second biggest city in Indonesia after Jakarta. With its population of three million generates ± 8700 m3 of domestic waste per day, which transported and disposed to final dumping site at Benowo. And the city also expected, the Benowo has a remaining lifespan of five years considering that securing land for a new dumping site is a problem that is currently facing by. Therefore, the city was compelled to reduce amount of the disposed waste by promoting the waste separation at sources level (household).

As a part of technology transfer to encourage the waste reduction, Kitakyushu International Techno-Cooperative Association (KITA) developed a method for waste composting for household and communal level in Surabaya City in 2004. The further replication of Takakura method, both of Takakura home-method (THM) for household application and Takakura Susun Method for communal level, was also implemented in Denpasar (Bali) in quite short time. This was the project outcome of “Promoting the Reduction and Recycling of Waste through Waste Separation at Source Collection and Composting in Surabaya Indonesia (FY2004 - FY2006), which was implemented by the aid of Japan Fund for Global Environment of the Environmental Restoration and Conservation Agency.

Overall, Surabaya city took the success of this piloting and the compost practising has reduced up to 25% of disposed waste to final dumping site in the year of 2007. In line with, the practicing of Takakura method which has nowadays widely spread disseminating all over Indonesia within these 2 years, it becomes necessary to identify and to learn for any further expansion.

The research activity for composting practices in Indonesia project is undertaking:
1. To survey how and where to the composting practices originated in Surabaya city have expanded in Indonesia
2. To identify the economic, environmental and social impacts caused by the dissemination
3. To learn further potential areas of expansion and necessary support for the replication.
