Egypt: According to Reuters, Arabian Cement Company has commissioned new alternative fuel processing machinery at its plant in Suez.

The state-of-the-art FLSmidth HOTDISC^TM allows Arabian Cement's plant to rely completely on coal and alternative fuels to run its operations. Moreover, it enables the plant to operate its kilns using alternative fuel materials directly, without the need to pre-treat them. Arabian Cement now has a designed fuel mix of 70% coal and 30% alternative fuels. The alternative fuel that will be used will be a mixture of agricultural wastes, municipal sludge and refuse-derived fuels (RDF). Alternative fuel use is expected to result in around 60,000t/yr of reduced CO₂ emissions.

Philippines: According to the Philippine Daily Inquirer, on 24 June 2015 the Pasig City government brought online what it described as, 'The country's largest facility for turning rubbish into fuel, capable of processing 600t/day of trash.'

The plant, which is Pasig City's joint project with the IPM Construction & Development Corp (IPM) and the Metro Manila Development Authority (MMDA), can process almost all of the city's daily waste production into refuse-derived fuel (RDF). Pasig City mayor Maribel Eusebio said that the plant would produce fuel pellets from the waste, which would then be supplied as an alternative fuel to cement plants. The RDF is majority-owned by Basic Environmental Systems & Technologies (BEST), a subsidiary of publicly-listed Minerales Industrias Corp, as well as France-based Lafarge Industrial Ecology International.

The plant mechanically segregates waste, selecting garbage with high thermal value that will be shredded, made into pellets and wrapped into bales. The plant is expected to convert 25 – 35% of the processed waste into alternative fuel for cement kilns. "The plant addresses serious concerns on increasing municipal solid waste and disposal," said Eusebio. "The RDF plant also complies with the waste diversion requirement of Republic Act No 9003 or Ecological Solid Waste Management Act of 2000. It also addresses climate change issues associated with how municipal wastes are managed."

The use of RDF in lieu of coal addresses the twin issues of solid waste management and climate change. "This is the largest RDF plant in the Philippines to date," said Isabelita P Mercado, president of IPM, which operates and manages the plant. "This is also a pioneering endeavour to save the environment by reducing our dependence on fossil fuel."

India: According to the Economic Times, the waste from city kitchens will soon be recycled into refuse-derived fuel (RDF) at waste processing plants in Kalaburagi City, Karnataka. The RDF from the 10 upcoming waste processing plants in Kalaburagi will be given to cement companies for use as fuel and the biodegradable waste will be used as manure by farmers.

The joint initiative taken up by the Karnataka State Pollution Control Board (KSPCB) and Karnataka Urban Infrastructure Development & Finance Corporation (KUIDFC) has had agreements with cement manufacturers such as ACC, Vicat Sagar and UltraTech in Kalaburagi.

"Plastic-like material is a good alternative for fossil fuel as it can replace up to 20% of fossil fuel in terms of energy," said KSPCB chairman Vaman Acharya. The pact is yet to be signed and talks between the stakeholders is in the final stages. Transport costs for the RDF are estimated to be less than US$0.016/kg.

The idea to use RDF instead of fossil fuel in Kalaburagi cement plants was first conceived by Hasiru Dala, a Bengaluru-based non profit organisation working on waste management. It has provided 100t of combustible waste to Zuari Cements' plant in Andhra Pradesh in the past two months. Nalini Shekar, founder of Hasiru Dala, said that the material was not sold to the cement plant for a price, but Zuari paid for packaging and transportation. Households have been asked to segregate waste and hand it to BBMP garbage collectors to make the process easier.

Paraguay: Industria Nacional del Cemento (INC) is looking to diversify its fuels mixture to include other types of oils and possibly biofuels. The company has signed an agreement with the engineering faculty at Asuncion National University (FIUNA) to certify the use of biofuels. INC's president Jorge Mendez believes that, from 2016, INC may start using a variety of fuels, following a US$50m investment in its furnace. This could save US$22m/yr, but it will not necessarily mean that biofuel will be used.

Egypt: Lafarge Industrial Ecology (Ecocem) has signed two major contracts to manage and operate existing refuse-derived fuel (RDF) platforms in Suez and Qalyubeya in Egypt.

In an effort to continue its efficient waste management processes, the company has signed a year agreement to renovate and upgrade the platforms in Suez and another separate 10-year agreement to manage and operate the existing platforms in Qalyubeya. Lafarge Ecocem has already added a new production line to the Suez platform and plans an additional line within one year of signing its contract with the governorate. The plant will produce 42,000t/yr of RDF and the investment will total US$1.66m.

Ecocem has also already added an extra line to the Qalyubea plant, in addition to renovating one production line. The company's future investments in the governorate will increase the RDF production capacity by 32,000t/yr to 280,000t/yr. Both investments at the Qalyubeya plant were funded by GIZ and the Bill and Melinda Gates Foundation with a total Investment of US$1m.

"In line with our 'Building Egypt 2030' campaign, Lafarge is committed to help solve the issue of waste in Egypt and to continue taking the necessary steps towards sustainable development," said Hussein Mansi, CEO of Lafarge Egypt. "At Lafarge Egypt, we feel it is our responsibility as a leader in building solutions to be the major proponents in waste management and plan to continue finding many opportunities to make a difference."

Building on its waste management strategy, Lafarge Ecocem is committing to several additional long-term contracts with different governorates to help convert municipal solid wastes to alternative fuels. In addition, in March 2015, Lafarge Egypt and Orascom Telecom Media and Technology Holding S A E signed a memorandum of understanding to develop a waste management framework of municipal and agricultural waste.

Lafarge Egypt and Ecocem have implemented many projects over the past three years in order to increase the use of alternative fuels and aim to achieve an average fuel substitution rate of 25% by the end of 2015. More than 260,000t of waste have been processed and fired in Lafarge's Sokhna plant since 2013, an equivalent of 100,000t of fossil fuels.

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."

Germany/Netherlands: HeidelbergCement has signed a six-year contract extension with waste management company Shanks Group for the supply of its ICOPOWER^® energy pellets.

Under the contract, Icopower, part of Shanks' Solid Waste Division, will supply HeidelbergCement with an increased volume of 54,000t/yr of the pellets, which are derived from commercial waste.

Shanks' production process includes a combination of sorting, drying and pelletising technology. In a statement Shanks said, "Unlike solid recovered fuel (SRF) or refuse derived fuel (RDF), ICOPOWER^® energy pellets are not classified as a waste product in the Netherlands."

India: 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."

Egypt: Tourah Cement plans to invest US$39.4m to convert its plant to alternative fuels to recover production ability and profitability. Tourah did not make a profit in 2014.

Austria: UNTHA Shredding Technology is currently working on proposals for more than 250 global prospects, eager to reap the benefits of its innovative new XR-C waste shredder. European orders in the last six months stand at Euro5m, with Holcim and SITA the most recent clients to invest in the machine.

The robust XR Cutter is able to produce high-quality solid recovered fuel (SRF) in a single pass, with double the output per tonnage of competing machines. Input material can include bulky untreated waste. When comparing like-for-like tonnages, the XR uses 50% less power consumption than traditional static electro-hydraulic shredders.

The power savings are due to UNTHA's new high-torque, slow-speed 'Eco Drive' concept. Modern water-cooled synchronous motors work continuously without overheating, ensuring minimal disruption and downtime. This also keeps running and maintenance charges minimal, with typical wear costs significantly less than Euro1/t.

"The beauty of the XR machine is its flexibility," said Peter Streinik, UNTHA's head of shredding solutions for waste. "The cutting concept is completely configurable, enabling alternative fuel producers to manufacture SRF with a homogenous pre-determined particle size of 100 - 400mm, or a precise SRF with a 30mm fraction or less. Load-dependent speed controls also enable the XR's RPM and torque to be adjusted and optimised, in order to achieve throughputs of up to 70t/hr."
