In an effort to step up waste management programmes, the Government recently inked the deals for two public-private partnership (PPP) projects and is on the lookout for developers for two more such projects.

The Waste Management Authority (Western Province) informed that two agreements had been endorsed on June 7. One involves waste to energy processing in Karadiyana (per day capacity of 500 metric tonnes {MTs}) for which an alternative developer had been identified (Fairway Waste Management Private Limited) and elsewhere, the Dambuwatta waste management project (per day capacity of 95 MTs) in Gampaha for which a developer had been identified (Trilogy ETC Private Limited). In the case of the former project, 150 MTs from the 500 MTs will be for biogas generation while the rest will be for incineration. The investment of the said project is USD/$ 73 million. Meanwhile, gasification technology is to be used in the Dambuwatta project. The investment for the Dambuwatta project is USD/$ 30 million.

While a developer has been identified for the processing facility in Gampaha (with a daily capacity of 400 MTs), a developer is yet to be found for the proposed mass scale facility for garbage from the Colombo Municipal Council (with a capacity of 500 MTs per day) and the proposed mass scale waste management program for the local authorities of the Kalutara District (with a daily capacity of 150 MTs).

Previously, in 2011 an agreement was endorsed with the private developer, RenewGEN Enviro Ventures India Private Limited with regard to the Korathota mass scale waste to energy facility (a capacity of 500 MTs per day) in Kaduwela on a five acre land after the developer had been identified. Yet public protests that ensued put a halt to any further establishment plans. With regard to the latter, Director of the Authority, Nalin Mannapperuma said that the developer had since agreed to shift to a land close to the same area. The developer’s investment is USD/$ 40 million to USD/$ 50 million. The incineration technology at the proposed facility is expected to generate eight to 10 megawatts (MWs).

“The Karadiyana project is expected to generate 11.5 MW, out of which 10 MWs will be uploaded to the national grid, which in turn will produce 80 million kilowatt hours sufficient to cater and supply electricity to 35,000 households. The Dambuwatta project is expected to generate 3.5 MWs.”
