Kiambu County Government's Kang'oki Semi-Aerobic Landfill Project is now starting to take shape.

The project which is the first of its kind in Africa, is modeled on the Japanese Fukuoka University’s technology application on solid and liquid waste management. It's aim is to have modern methods of disposing waste that will reduce fire outbreaks, insects, rodents, bad odour, global warming and increase land aesthetic value. 

The Fukuoka method involves consolidating waste through a series of pipes assembled at the bottom of the landfill that due to their perforated structure, guarantee optimum aeration and decrease the release of toxic gases. 

The pipes also allow leachate to easily discharge from the landfill into a secure retention pond before being transferred to a nearby sewage facility for treatment and release. It has a comparative advantage over other waste management formulae because 70-100 tons of waste will be managed daily in addition to a leachate treatment system.

The leachate collection pipe, comprising the perforated main and branch pipes and gravel, is laid at the bottom of the landfill to discharge the waste as quickly as possible. Leachate is water that has percolated through a solid and leached out some of the constituents. It will involve the separation of re-useable waste from non re-useable waste such as polythene bags, plastic etc so as to re-cycle this waste material for other uses. 

Once complete, it will offer waste management solutions and assist in the production of free fertiliser for the Kiambu farmer. Its introduction will also help to maximise land use and ensure proper solid waste management. 

The next stage now is the embankment which is a wall of earth or stone built to prevent the waste from flooding the area.  

The project, funded by the Swedish Embassy, Kiambu Government, UN Habitat and the Lands Ministry, Housing and Urban Development at a cost of Sh114 million, was launched on March 23rd 2015 with the construction works kicking off on the 20-acre parcel kicked off sometime in May the same year. The county government plans to later expand it later to cover 50 acres.

 The county government is supported by UN-Habitat, through a joint collaboration with the County Government of Kiambu, Jomo Kenyatta University of Agriculture and Technology (JKUAT), Embassy of Sweden and Japan’s Fukuoka University.

The Kiambu government plans to launch it in the first quarter of 2016.
