South Korea: A new solid recovered fuel (SRF) production facility is now fully operational in Wonju City, South Korea, thanks to global shredding company UNTHA and local partner PERITUS.

Korean waste management specialist Zion has built the SRF manufacturing plant to make smarter use of its residual materials. Now, with the new system in place, pre-sorted construction and demolition waste and commercial and industrial waste, is being shredded to produce a homogenous 50mm fuel for the cement industry.

The UNTHA XR3000C shredder with cutting concept was chosen following a series of trials at UNTHA's Austrian headquarters. Demonstrations showed that the technology could comfortably achieve throughputs of 60-70t/day, with scope to almost double that moving forward. The XR3000C's flexibility also means Zion can achieve a 40-50mm particle size from the single step shredding of plastic bales, which has further boosted the company's SRF production capabilities.

"South Korea may only be in the infancy of its waste-to-energy journey, yet the nation has formed a very sophisticated and disciplined approach to its waste roadmap relatively quickly. Legislation is in place to drive the production of <50mm SRF and the necessary infrastructure is fast evolving to accommodate this," said UNTHA's Head of Business Unit Waste Peter Streinik. "What we see here with Zion, however, is not just a company striving for compliance. They're prioritising energy efficiency, profitability and innovation too, to realise the wider benefits that come with smarter waste management."

Committed to principles akin to Europe's waste hierarchy, Zion extracts as many materials as possible, including bricks, metal, sands, glass and batteries, for re-use or recycling, prior to them entering the SRF manufacturing stream.

"Our family-run business is incredibly passionate about renewable energy, from solar power to alternative fuel production," said Zion's President Geumju Kim. "Now that our new SRF plant is up and running, with state-of-the-art configurable technology in place, the next step is to investigate relationships with different customers. We can satisfy varied specifications, and look forward to improving South Korea's resource agenda."

Ireland: Irish Cement will burn used tyres in a bid to cut costs and secure jobs at its Limerick plant. The company plans to switch to dry waste material such as rubber from used tyres and plastic to heat the kiln at the plant. The switch will cut costs, make the plant cleaner and more competitive, according to the company.

A spokesman for Irish Cement said that the company would shortly be lodging a planning application with Limerick City and County Council for the replacement of fossil fuels with alternative fuels and raw materials to improve the sustainability of their operations. The company will also be seeking a revision of its licence from the Environmental Protection Agency.

"Limerick is Ireland's oldest cement plant, having commenced operations 77 years ago. Its continuous operation has been sustained by continuous investment in new technologies and processes. After the recent period of reduced demand, production is once again on the increase at home and abroad for cement. This fuel replacement programme will be key to sustaining this growth," said Plant Manager Pat Robinson. "Based on experience in other cement plants in Ireland and throughout Europe, the opportunity to reduce our dependence on imported fossil fuels will prove critical to our ability to operate competitively and sustain jobs at Irish Cement Limerick into the future."

Tanzania: Dangote Cement has signed two agreements that will enable its US$600m cement plant in Tanzania to generate 150MW from coal.

One agreement is with Tancoal. Dangote Cement has also signed a coal prospecting licence for a site in Mbinga. However, the plant will first run on diesel until it is able to generate its own electricity from coal.

The deals ends a year-long dispute between the government and the cement plant after Tanesco failed to provide electricity. The plant was considering importing coal from South Africa, which was a cheaper option than buying it from the area.

The cement plant is expected to reduce cement prices by 50% once production commences in early 2016. It will take advantage of the growing construction industry, which contributes 12.5% to the country's GDP. It will offer more than 1500 direct jobs and 9000 indirectly.

China: Eleven people have been detained in Yangchun, south China's Guangdong Province, after demonstrations against a project to build a waste incinerator adjacent to a cement plant turned violent.

Protesters said the demonstrations drew hundreds of people agitated over the risk of pollution from the project."How will we survive breathing in noxious smoke?" said one of the protestors.

Tension persisted for two days, with protesters saying that hundreds of people had been gathering near the gates of the cement plant.
