An expert committee which evaluated the technical bids for truck-mounted incineration units has sought more technical details from the firms which have evinced interest in providing them.

Four firms, including two foreign ones, had responded to the global bid floated for the units. The bids were floated following a decision of the State government to procure two mobile units. The government decided to go for the mobile units considering the public resistance to the waste treatment plants in many parts of the State.

Re-examination of bids

After inspecting the technical bids provided by the firms, the committee asked the firms to provide some more information. The bids will be re-examined after the firms submitting the additional details, said K. Sajeevan, chairman of the Kerala State Pollution Control Board, who headed the committee.

The firms have been directed to submit the details immediately. Once the technical bids are evaluated, financial bids will also be examined to take the final decision, Mr. Sajeevan said.

The government had floated the bid for one unit which can treat municipal solid waste up to 1 tonne per hour and another one with the capacity to process 3 tonnes of waste. The units should be able to process waste with organic matter forming about 70 per cent of its content. Inorganic matter including construction and metal waste would also have to be processed.

The refuse will have “a calorific value average 1000 Kcal/Kg” and 70 per cent moisture content.

The incineration facility should be totally mobile and can be transported on a truck/trailer with a hydraulic gripping device and the technology engaged by the units should be demonstrably safe, according to the tender conditions.

A demonstrably safe technology is one that achieves the highest possible level of occupational safety and has a history of safe operation. The technical concept should comply with the environmental standards of India and the bidder should apply the best available techniques and best environmental practices, it has been specified.

The technology engaged by the firm should operate in an essentially closed system and ensure complete incineration.
