UK: Saxlund International has collaborated with Hope Construction Materials to install and commission a new waste-derived fuel solution for Hope Construction Materials' cement plant in Derbyshire, UK. The solution has been designed to provide storage, transportation, weighing and injection of solid waste fuel (SWF) to the two kilns. The goal is to increase the rate at which Hope can replace fossil fuels with waste-derived alternatives to more than 50%, a key part of its long-term sustainability targets.

The project incorporates a fuel reception and push-floor storage solution, reclaim conveyors, process tower with drum magnet and star screen, together with a weighing and pneumatic injection system to the main burners. The system facilitates stable and reliable process conditions to help minimise build-up in the pre-heater tower. It also offers a 'future-proof' solution with the flexibility to handle changing fuel characteristics and different types of waste-derived fuels, should suppliers change in the future.

"This is a flagship project for us. Once fully operational, the new solid waste fuel (SWF) system will run on a 24/7 basis delivering fuel at a rate of up to 5t/hr to each kiln," said Matt Drew, managing director Saxlund International. "It means that Hope Works will soon be operating with a significantly larger proportion of waste-derived fuels, in the process diverting up to 80,000t/yr of bulk solid waste from landfill and representing significant carbon savings to the business."

Egypt: Investments worth US$30bn in the coal industry are expected to be conducted within the next five years, according to Egypt's investment minister Ashraf Salman.

Salman said that there is 'full coordination' between the ministries of environment, electricity and investment to adhere to international environmental standards when using coal. Egypt's cabinet announced new rules on coal use in April 2015, which stipulate that coal imports can only take place after approval from the ministry of environment. The new rules are an amendment to a law on environmental affairs and allow the use of coal for cement, iron and steel, coke and aluminium production and in power plants.

Salman said that using coal as an energy source would decrease the dependency on natural gas as a primary energy source and petroleum products in steel and cement production. Despite the energy crisis, which has caused frequent and numerous power outages for years, the cabinet's approval of new coal use has caused controversy both within the government and outside.

Egypt: 90% of cement plants have agreed to use coal to increase their cement production, according to Egypt's Industrial Development Authority.

The authority is facilitating plant upgrades to enable coal use and ensuring that the necessary quantities of coal can be supplied, according to the head of the Industrial Development Authority, Ismail Gaber. He added that Egypt needs more than 32Mt/yr of cement to meet the needs of the domestic market.

In light of the population increase, the demand on energy has significantly increased in Egypt in recent years. The government agreed to include coal in the cement industry energy system in April 2014. Prior to that, coal was used only in the iron and steel, coke and aluminium industries. It is now also allowed to be used for electricity and cement production.

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.
