Plan afoot to utilise city garbage for fuel

- POST REPORT, Kathmandu

Jun 12, 2014-

To attract private sector towards the prospect of making money by generating energy from municipal wastes, a Nepali company is planning to introduce a new biogas technology that uses solid organic wastes to produce gas, electricity and fuel.

The Future Energy Development Company is planning to introduce in the next few months the plug flow type biogas digester in Nepal that offers an array of innovative new technologies for converting organic wastes into valuable resources.

The company said that the biogas digester manufactured by Finland based BioGTS company is being launched in an attempt to encourage engagement of private sector as well as the government to utilise the municipal wastes into generating energy and contribute to energy security in the country.

“We have already started consultation with government bodies, private companies and individuals on proper management of municipal wastes and relevant technologies that could help in solving the problems of both garbage management and energy crisis at municipal level,” said Bishwa Nath Ghimire, managing director of Future Energy Development, adding, “We are working to connect Nepali companies with international companies to solve the critical problem of energy crisis and waste management facing Nepal.”

According to Ghimire,  unlike the widely used bio-gas technology in Nepal (in which cow dung, as a raw material, undergoes anaerobic digestion process to produce methane that is used for cooking purposes), the plug

flow reactor is designed

to deal with wastes like

organic solid wastes, green leaves and sewage sludge to produce energy.

There are four basic components involved in the technology—— waste separating plant to segregate the collected municipal wastes into organic and non-organic matters, plug flow reactor, biogas upgrading system and a generator to produce electricity.

At present, the company has plans to introduce the technology only for commercial purpose and is planning to include wastes generated from large scale households, industries and restaurants within the municipality area.

“Though, the government is planning to involve the private sector to manage municipal wastes and generate energy, yet, there is lack of policy to encourage this kind of intervention,” Ghimire said. Meanwhile, the Alternative Energy Promotion Centre under the Ministry of Science, Technology and Environment is working to engage private sector in energy management including municipal wastes.

In 2012, a study conducted by Asian Development Bank had put Kathmandu in the top for producing 479 tons of municipal wastes per day followed by Pokhara, Lalitpur, Bharatpur and Biratnagar which produced 117, 84, 59 and 58 tons of solid wastes every day.   

The study had found that Kathmandu has the capacity to produce 103.8 megawatt of electricity from 34,638 kilogram of organic wastes the city produced every day.
