The plant has the capacity to handle 100 tonnes of garbage a day and will resolve the garbage woes of more than 20 villages instantly. To sweeten the deal, the facility will also generate electricity from the waste.

The stress posed by garbage on North Goa’s tourist belt is set to be alleviated with Goa inaugurating a state-of-the-art, 145.95 crore, solid waste treatment facility at Calangute.

The Euro-designed plant is a state-of-the-art modern facility based on mechanical biological treatment (MBT) process with proper segregation, recovery of recyclables and bio-methanation process. The state government has claimed that it is the most modern garbage treatment plant in India. The machinery for the sophisticated facility has been sourced from Europe and America. The machines, sourced and supplied by the  Netherlands based db Technologies BV, help turn waste into resource such as manure
and electricity.

The plant sorts and treats garbage through:

  • A plastic bag opener sourced from Germany
  • Material segregation and organic extrusion machine from Germany
  • 􀀃􀀃Biomethanation composter from Italy
  • 􀀃􀀃Screening and wind sifter from Germany
  • 􀀃􀀃Biogas electricity generator from USA
  • 􀀃A special landfill zone has been earmarked for sanitary waste

The plant has minimum human intervention and most of the processes are computer-controlled

  • Composting and maturation of dewatered sludge will produce manure
  • The functioning of the plant and selection of technology has been done on the basis that all issues of odour, unsightly garbage mounds and leachate generation are addressed and minimized
  • Mechanical units, manual sorting station, baler press, organic extrusion – single-step automatic segregation and homogenization, bio-methanation units, sludge dewatering, in-vessel composting drums, and compost screening technology
  • 􀀃The garbage is put on a conveyor belt and is manually sorted in bins by a handful of workers
