Quotations submitted by four bidders for the government’s public tender for the design, construction and 15-year-operation of an organic waste recycling centre in Cotai range from 1.8 billion to 3.2 billion patacas, the Environmental Protection Bureau (DSPA) announced in a statement yesterday.
The organic recycling centre will be located next to the city’s only construction waste landfill in East Cotai.
The government launched a public tender in November last year for the centre’s design and construction and 180-month operation.
The deadline for bid submissions for the public tender ended on Wednesday. A total of four companies submitted their bids, which were unsealed by DSPA officials yesterday. All bids were accepted.
Yesterday’s statement noted that the bureau has set a maximum period of 48 months for the winning bidder to complete the project’s design and construction.
The organic waste recycling centre, which will cover an area of around 30,000 square metres, will comprise kitchen waste processing plants and wastewater treatment plants.
Yesterday’s statement noted that the organic recycling centre will generate electricity through biogas, i.e., a type of renewable energy similar to natural gas, generated by anaerobic digestion.
According to the statement, in the first phase after the centre comes into use, it will be able to process 150 tonnes of kitchen waste per day, and 420 cubic metres of wastewater per day transported by tanker trucks, namely greasy wastewater retained in grease traps in kitchens in restaurants, and wastewater from mobile toilets set up on construction sites.
