Access Engineering speeds up Ganemulla flyover construction, to be completed in May 2017

Access Engineering backed by experience and expertise in flyover construction in Sri Lanka, is making a swift progress in the Ganemulla flyover project to ease traffic in Ganemulla.

The project is spearheaded by the Road Development Authority and is funded by the Government of Spain. The design and the supply of the superstructure are entrusted to the main contractor; Centunion S. A of Spain and the design of sub structure, onsite fabrication, installation and erection are subcontracted to Access Engineering along with the construction of approach roads and associated civil works.

The project emerged as a permanent solution to the situation, involves the erection of a 256m long flyover which is comprised of 3.5m wide two lane carriageways and 1.2m wide two pedestrian ways. The flyover is built on a pile foundations and seven span steel superstructure. The steel components of the super structure including piers, girders and decking are imported from Spain through the main contract and are available onsite ready to be installed.

The erection of steel bridge piers and onsite fabrication works including splicing of bridge beams are in progress and a significant percentage of the substructure of the development is now completed. The scope of the project also includes the construction of 330m long approach roads of which earth work is now commenced and progressing.

“As the development is progressing in the middle of a highly congested urbanity, Road Development Authority and Railway Authority are frequently consulted to ensure the operation progresses with minimum disturbance to the rail and vehicle traffic and the daily commuters of the neighbourhood,” Project Manager Jeewaka Dayanakaya said.

The project is to be completed in May 2017.

Sri Lanka Fairway group to make fertilizer, electricity with garbage

Apr 21, 2017 18:25 PM GMT+0530 | 0 Comment(s)

ECONOMYNEXT - Sri Lanka's Fairway group which won a waste management concession said it will process 500 tonnes of garbage a day into power and fertilizer using an incinerator and an organic waste decomposition plant.

Fairway Waster Management (Pvt) Ltd was given the Thumbowila-Karadiyana waste dump, in a suburb of Sri Lanka's capital Colombo, which already has two million tonnes of waste which is leaching into nearby waterways, land and the air.

The site is emitting large volumes of methane (the main component of biogas) which can be seen bubbling out of leachate around the area. The firm says and sulphur and nitrogen oxides are also emitted to the air.

"While the project will not stop the current level of emissions immediately, the organic waste that will be kept out of the landfill will stop future emissions from occurring," Fairway said in a statement.

At another site in Meethotamulla, in Colombo, over 30 people died and over 100 houses were destroyed after piled up waste generated a rotational landslide.

Fairway will build a 425 tonne a day, mass burn incinerator, using Danish and German technology complying with European Union standards.

The firm says it expects to generate 79 million units of electricity from a waste driven power plant.

The government had earlier proposed that the state-run Ceylon Electricity Board pay 36.20 rupees a unit for 20 years for the power generated.

At the moment the site receives small amounts of waste separated at source, as well as large volumes of mixed municipal garbage.

Industry analysts say in Sri Lanka, municipal waste has a large portion of moist food waste and less high calorie material that can be burned to produce power.

Fairway said it will build biological treatment plant that will process fast-degradable, high moisture content organic waste in a wet fermentation anaerobic digestion system.

Biogas generated from the process will also be used to generate power.

This system will treat a maximum of 115 tons of fast degradable organic waste per day.

About 45,000 tonnes of liquid fertilizer and 7500 tonnes of solid fertilizer will be produced at the site.

Processing will reduce the solid material that will eventually go to a landfill by 90 percent, the firm said. (Colombo/Apr21/2017)

Fairway Waste Management on a Mission to Transform Colombo into a Waste-Free Clean City

2017-04-21 15:41:41

In the aftermath of the recent unfortunate incident in Meethotamulla, the ‘Waste Free-Clean City project in Karadiyana, which has been awarded to Fairway Waste Management (PVT) Ltd, is a timely measure towards ensuring that such a national calamity will never occur in future again. Following the launch of this Project by the government, Fairway Waste Management has begun the task of putting their plans into action.

Introduction

Fairway Waste Management has come up with a proposal to develop a solid waste processing facility at the Thumbowila-Karadiyana landfill site located in the Western Province of Sri Lanka. This will be an integrated waste processing facility to process 500 tons per day of fresh municipal solid waste received at the site. The proposed facility is designed to maximize energy production while having minimum environmental impact by optimizing the recovery of energy and nutrients in the waste stream. The processing facility will reduce the amount of waste diverted to landfills by as much as 80% by mass and 90% by volume, whilst the fraction, which will be disposed in a suitably prepared landfill is mostly inert with no ill effects on the environment.

The design consists of a biological treatment plant that will process the fast degradable, high moisture content organic waste in a wet fermentation anaerobic digestion system. This system will treat a maximum of 115 tons of fast degradable organic waste per day. The remaining waste will be diverted to an incinerator facility having a capacity of 425 tons per day.

The project will supply a total of 79,000,000 kWh of electricity to the grid per year. This is sufficient to supply the demands of 35,000 households (based on the World Bank per capita energy use in Sri Lanka). In addition to electricity, the plant will generate liquid and solid fertilizer from the biological treatment of the organic fraction of the waste. It will produce 40,000 tons of liquid fertilizer per year, which will be processed to a high quality bio-fertilizer for the local market.

The environmental and social impacts of the current situation surrounding the management of waste disposal

Currently the mixed municipal waste as well as the source segregated household and commercial waste from eight local authorities is disposed at the Karadiyana waste-processing site. A small fraction of the source-segregated waste is processed as compost. All of the mixed waste is land filled. While the landfill is a managed landfill it does not meet the modern standards for a landfill by any measure. The site, which has been operational for several decades, contains more than 2,000,000 tons of waste that is polluting the surrounding waterways, ground water sources and the air. The environmental externalities due to open dumping caused by the site are palpable. Fairway Waste Management has estimated the monetary cost of the externalities, to the public, due to air pollution, GHG emissions etc. to be approximately LKR 6000/ton. The actual cost to the Country is much higher due to the negative social impact, cost of health care (attributed to negative effects of the dump on surrounding communities), present value of future cost of remediation, cost for law and order arising from public protests, opportunity cost of the land etc.

The 'Waste-Free Clean City’ Project

This is an initiative by the Ministry of Megapolis and Western Development to reduce waste as well as to find better and modern waste disposal solutions. The basic idea is to implement and enforce the 3Rs (Reduce, Reuse Recycle) principal and to effectively implement sustainable and environmentally sound end-of-the-pipe waste solutions, such as mass burn incineration and biological treatment facilities. Sri Lanka has a long way to go. A city will never be waste free, however, we can avoid piling the waste in landfills or rather minimize it. Incineration is the only way to do this and it is a must have solution.

Workings of the "Waste-to-Energy" Concept

As far as Fairway Waste Management is concerned waste has an intrinsic value. It contains recoverable nutrients as well as energy that can be recovered through thermo physical or biological processes. All things when supplied with enough heat will burn releasing most often more energy than that was required to start the combustion process. One can think of a roadside garbage pile that is set on fire with a single match. If there is enough material with low moisture content it will burn releasing energy as heat in to the atmosphere. A mass burn incinerator facility is simply a system that recovers the heat and converts it to electricity. It also cleanses the smoke and particulate matter that is released in the combustion process. It is possible to incinerate all of the waste but doing so is not the most environmentally sound solution, and it can be inefficient to burn the high moisture content waste consisting of fast degradable organic waste. It is for this reason that Fairway Waste Management has incorporated a biological process to treat the organic fraction so that not only energy but also nutrients are recovered from the waste stream. The decomposition of organic matter can occur in the presence of oxygen, aerobic decomposition, and in the absence, anaerobically. Anaerobic decomposition is a naturally occurring process that produces biogas-containing methane as a byproduct. In fact anaerobic decomposition is an ongoing process deep in the Karadiyana landfill, which produces biogas. Biogas consists of methane, CO2 and water vapor. Methane is also known as natural gas that escapes in to the atmosphere where it acts as a potent green house gas. However, if the process is controlled and the bio gas is collected it can be combusted to produce electricity. Fairway Waste Management will install the largest and most advanced anaerobic digestion system in the region in Karadiyana to treat as much as 36,000 tons of organic waste per year. Additionally as a byproduct the plant will produce 45,000 tons/year of liquid fertilizer and 7500 tons/year of solid fertilizer.

Parties Involved

Fairway Holdings and Sustainable Alternatives (Pvt) Ltd formed a consortium to bid for the project when the Ministry of Megapolis and Western Development called for proposals in 2016.

The project was supported by numerous other government agencies such as:
The Waste Management Authority
The Western Province - Provincial Government
The Ministry of Megapolis and Western Development
The Urban Development Authority

Technology

The technology involved, mostly consists of a mass burn incineration with energy recovery boiler and an advanced flue gas cleaning system meeting European Union emission standards. The incinerator is a moving grate type with a four-stage heat recovery boiler. The flue gas cleaning system will assure that the emissions exceed the standards required in the country and will meet EU2010 emission standards. The plant design is based on The European Union guidelines for Waste Incineration. Fairway Waste Management will be utilizing expert consultants from Denmark and the Netherlands to design and commission this project.

Environmental, Social and Economical Benefits of the Final Outcome

There will be a significant reduction of the volume of landfill by more than 90%. The project will produce green electricity to power more than 35,000 households. Apart from saving the country’s fossil fuel (coal and heavy diesel) used to produce power, the project will be an immediate benefit to the communities that live around the Karadiyana garbage site. At the moment the site emits large volumes of methane from waste that is digesting anaerobically. It can be seen bubbling out of puddles of leachate. Methane is a potent green house gas with an environmental impact that is 20 times more than that of CO2. While the project will not stop the current level of emissions immediately, the organic waste that will be kept out of the landfill will stop future emissions from occurring. It will eliminate the leachate that now washes into the ground and surrounding water bodies and it will also reduce the levels of SOx and NOx (harmful GHG emissions) in the landfill area. The lack of fresh waste in an open dump will eliminate the rodents and mosquitoes that can breed and spread diseases. The commissioning of the project will be the beginning of the reclamation process of the land that at present is an eye sore to the surrounding communities.

Public Outreach

Fairway Waste Management will contribute to capacity building by working closely with local universities on the project. As of now there are several academics who are experts in solid waste management, biological waste processing and thermal processing who are working with the government and with Fairway Waste Management on this project. These relationships will no doubt be further strengthened by actively involving research students and academic staff on areas of mutual interest. This facility will be used to encourage and help the academic staff from universities to learn about the latest technologies in waste management. The plant operators will be trained by the best in the industry and the engineering staff will be hired locally to run the plant with specialized training provided to make the operation and maintenance of the plant a local effort. It can be confidently stated that Fairway Waste Management’s CSR efforts will contribute towards building a community of experts that will lead the waste-processing sector in the country in future.
