SHILLONG: If a proposal to the State Government takes shape then the city’s domestic waste scenario could change forever.
The State Government is contemplating to implement a Bio Gas Plant to treat wastes using Czech technology, known world over for waste management techniques, following a meeting with the Ambassador of the Czech Republic to India, state government official and others, recently.
The Bio Gas Plant project is likely to be designed and implemented by a New Delhi based firm Vitkovice India Power Pvt. Ltd. (VIPPL) according to the local conditions. It is learnt that the domestic waste generation in Shillong city is 100MT per day and to carryout these Bio Gas Projects collaboration with a local partner, state owned or undertaken companies, is needed. This will provide Czech technology while employing local people here, which have always been a major bone of contention, after land, towards every developmental project. Such an initiative will do much good to the citizens of the city, which has seen large scale rise in population and the inability of the civic bodies to contain wastes as a result.
VIPPL uses wet fermentation methods in Bio Gas Plant which means the maximum waste should be liquid and solid waste under 15% with all bio-degradable wastes are suitable. The firm has submitted to the state government eight type series of Bio Gas Stations (BGS) and an essential performance parameter of the BGS series is reliable daily biogas production.
The BGS will be fed with agricultural wastes, kitchen wastes, sludges and other biological wastes to generate electric power, heat, treated biogas and stabilized material. Biogas is generated through microbial degradation of organic substances without access to oxygen (anaerobic fermentation) and is transformed into electric and heat power in a cogeneration unit.
There is also a possibility to modify biogas into parameters of natural gas or compressed natural gas (CNG).
