Canada: The Metro Vancouver government body is considering sending its refuse as refuse derived fuel (RDF) pellets to the Lehigh Cement plant in Delta. The scheme is one of three new options the body is considering to manage its waste including incinerating it to produce electricity or gasification, according to local media.
"There's no electricity produced, but it would be a benefit because it would result in no increased air emissions. The others (mass burn and gasification) would have new emissions," said Sarah Wellman, project manager of Metro Vancouver's waste-to-energy project, in relation to the cement plant option.
Metro Vancouver is waiting to hear from the provincial government on how to proceed. The area currently generates electricity from the Covanta Burnaby Renewable Energy incineration plant.
Jaipur Municipal Corporation plans waste-to-energy plant
08 April 2015India: The Jaipur Municipal Corporation (JMC) plans to set up small-scale waste-to-energy plant to generate electricity. A Bangalore-based private company, which has been appointed for the project management, will submit a project report in four months. The JMC plans to generate nearly 6MW/day from 650t of waste.
"At present, JMC generates close to 1250t/day of waste," said deputy mayor Manoj Bhardawaj, "Of this 1250t, 350t is used to produce refuse-derived fuel that is sold to cement plants and 250t is used to produce compost manure. We are planning to generate electricity from the remaining 650t."
Commissioning to start at new UK SRF facility
12 February 2015UK: SITA UK has completed the construction of its Solid Recovered Fuel (SRF) manufacturing plant at Malpass Farm in Rugby, Warwickshire. The plant will undergo a series of commissioning tests over the next few months before starting full-scale production of Climafuel SRF. This will be used to power the kiln at the adjacent Cemex UK Rugby cement plant.
The residual waste material arriving at the site will primarily be collected from commercial and industrial businesses across the region that would otherwise go to landfill. Once received on site any metals, plastics and paper will be extracted for recycling. Similarly, materials with a high chlorine content, which could damage the kiln, will also be extracted. Any residual waste material that is removed from the production process will be processed into refuse derived fuel (RDF) for use in waste-to-energy applications.
To produce the SRF, the remaining material is sifted, shredded and blended while being continuously analysed using infrared technology. This allows the plant operators to ensure that the fuel, which has a confetti-like consistency after processing, has the precise chemical composition and calorific value required by Cemex UK.
SITA UK's Head of Alternative Fuels, Andy Hill, said, "The residual waste material that will be delivered to this facility would have gone to landfill but, instead, we are going to take out anything that can be recycled and then turn what's left into a replacement fuel."
"We have been producing this fuel very successfully at our sister plant at Landor Street in Birmingham for the past couple of years, but this new facility implements the latest technology and will substantially increase our production capacity," continued Hill. "Between the two plants, we'll be producing around 250,000t/yr of Climafuel."
SITA UK is currently also investing in new SRF manufacturing facilities at the Port of Tilbury in Essex, which are currently under construction. SITA UK currently supplies SRF to CEMEX UK and to CEMEX Latvia.
