The Karadiyana Waste Management Project in Werahera seems to have turned into a case of a mismanaged landfill while new residents are occupying the area that was deemed risky for people to live in by the authorities.
In the early months of 2019, when the Karadiyana garbage site was becoming dangerously steep and reaching a similar height of the Meethotamulla garbage mountain, indicating signs of collapse, the area residents were asked to evacuate by the officials from the Kesbewa Divisional Secretariat.
Under these circumstances public private partnership agreement ( PPA ) was signed with Fairway Holdings for a waste treatment plant in Karadiyana, where 500 MT of waste were to be processed into energy.
However Sri Lanka’s largest publicly listed power company Windforce Ltd. Has now steeped into to fast-track the development of the Karadiyana Waste to Energy Power Plant, having signed a share sale and purchase agreement with Fairway Holdings Ltd
The project has been delayed due to official bottlenecks although it was commenced in August 2017 with an investment of $ 91 million, was to add 10 MW of electricity to the national grid. The Government was to buy power generated from the plants at a tariff of Rs. 35.10 per unit, which would increase later.
However it was suspended due to issues raised by the CEB, followed by the Ministry of Finance, the Ministry of Power and Renewable Energy, and the Treasury.
At this point, the developer had spent a sum of Rs. 1,312 million on the project over engineering design, site preparation, advance payments, and civil works (completing 90% of the piling work), but was forced to stop work and demobilise from the site.
Generating power from garbage could incur an additional cost of Rs. 3,000 for a tonne of waste. Thus with 1,500 tonnes a day, the additional daily cost would be Rs. 4.5 million or Rs. 1.64 billion a year.
However Sri Lanka’s largest publicly listed power company windforce Ltd. Aims to fast-track the development of the Karadiyana Waste to Energy Power Plant, having signed a share sale and purchase agreement with Fairway Holdings Ltd.
With this agreement, windforce acquires a controlling stake of 92.5% in Fairway Waste Management Ltd.
Renowned for introducing breakthrough technology to Sri Lanka’s renewable energy industry, the Karadiyana Plant will reflect that cutting edge prowess with a 400 metric ton per day incinerator plant and a 100 metric ton per day anaerobic digestor, together generating 10MW of electricity to the National Grid.
The plant, located just 15 km away from central Colombo, can accommodate a total of 500 metric tons of input daily, which will be a significant contribution to manage the 7,000 metric tons of daily waste being accumulated in Sri Lanka, of which 60% is from the Western Province alone.
Once commissioned, the anaerobic digestion plant will produce bio gas through the input of organic waste, while the incineration plant will generate high pressure steam to operate a steam turbine.
