The municipality of Ponta Grossa in the Brazilian state of Parana is considering a biogas plant that could meet up to 30% of the energy consumption in local public buildings.
Under its sustainability programme, Ponta Grossa is seeking to implement a plant powered by gas from organic waste. City representatives have already met with technicians from the International Center for Renewable Energy-Biogas (CIBiogas), who presented a technical and economic feasibility study for the project.
The feasibility study suggested that at maximum capacity, the burning of organic waste could offset up to 30% of the energy used by public structures in the municipality.
“The proposal of this plant is part of the package of measures we are taking for waste management in the city, working exclusively with organic material,” explained environment secretary Paulo Barros. “Thus, a selective collection of large organic waste generators would be performed and sent to the plant. There, the waste goes through a process of decomposition of matter, generating gas and then electricity.”
The plant will have an initial processing capacity of 12 tonnes of organic waste per day, with a potential to expand to 30 tonnes per day. At this maximum capacity, the city could reduce costs by around $270,000 (€244,738) per month, which includes savings associated with avoiding the disposal of waste in landfill.
Barros added that the city is considering the roll-out of electric vehicles across its local fleet in the future.
