US: The Indiana Department of Environmental Management will hold a public hearing about the use of liquid waste-derived fuel at the Essroc Cement Speed plant. Essroc Cement is applying for a state environmental permit to burn liquid waste-derived fuel in one of its cement kilns in the unincorporated Clark County community of Speed. Residents have expressed concerns about the plants. No date for the meeting has been set, according to Associated Press.

Mike McHugh, the Speed plant's director, said Essroc plans to use products mostly from the petroleum industry, such as paint thinners, antifreeze and acetone. The plant will have to build two small storage facilities for it to start replacing about 25 – 30% of the coal it burns with liquid waste-derived fuel.

Essroc Corporate Environmental Engineer Luis Rodriguez said the company welcomes the public's questions. The company hosted an open house and talked with community leaders in 2014 before it submitted its application. "We actually want it to go to public comment so we can answer some of these questions... We've wanted to be as upfront on this as possible," said Rodriguez.

US: A waste-to-solid-fuel plant has broken ground in West Virginia. Its developers say it is the US' first resource recovery facility that employs mechanical biological treatment (MBT).

The waste-to-solid-fuel plant in Martinsburg, West Virginia, called Entsorga WV, is expected to be operational in early 2017. Entsorga WV is a joint venture between Apple Valley Waste Technologies, Entsorga USA and Chemtex International.

By utilising the HEBioT MBT system, Entsorga WV will recover biomass, plastics and other carbon based materials from the mixed municipal solid waste (MSW) stream and convert them into an alternative fuel. When processing the MSW, Entsorga WV will remove other recyclable commodities such as ferrous and non-ferrous metals. The MSW received will be converted to solid recovered (SRF), which will be used as an alternative or supplement to fossil fuels.

The plant will be able to produce about 50,000t/yr of SRF, which will be delivered to the Essroc Cement Plant and used in conjunction with coal. The companies have entered into a long-term contract for the provision and acceptance of the SRF.

The reduction of waste that will be disposed of in landfills as a result of the Entsorga facility will result in a greenhouse gas emission reduction of 28,000t/yr of carbon dioxide equivalent. There are currently more than 330 MBT plants in operation throughout Europe, processing more than 30Mt/yr of municipal solid waste.

US: The Michigan Department of Environmental Quality (DEQ) has granted approval for Lafarge North America to use scrap plastic and asphalt shingles at its cement kilns in Alpena, Michigan State.

Lafarge had requested to be allowed to burn additional fuels in the five cement kilns at its cement plant. Prior to receiving approval to use plastics and shingles as a fuel, the company had used coal, petroleum coke, clean wood and non-halogenated polyethylene and polypropylene as fuel. In its application, Lafarge said that it could use nearly 140,000t/yr of plastics, more than 82,000t/yr of wood and 54,673t/yr of shingles as a replacement fuel for the coal and coke.

Lafarge was issued a permit in 2012 to install technology to allow for a trial burn of shingles in the kilns. The permit required Lafarge to conduct stack testing for emissions of concern from the combustion of shingles. The emissions testing demonstrated that the emissions were less than what Lafarge had originally estimated, according to the DEQ.

Following analyses conducted by the DEQ, staff concluded that the proposed project would comply with all applicable federal air quality requirements and with all of the Michigan DEQ Air Quality Division regulations. The staff concluded that the project, as proposed, would not violate the federal policies.

US: Regulators have scheduled a public hearing about Holcim's request to change the way it burns liquid wastes for fuel at its Holly Hill plant in South Carolina.

"We currently burn fuel in one place in the kiln and this permit will allow us to burn it further along in the process," said Holcim spokeswoman Robin DeCarlo. "It does not change the limits, but allows us more flexibility." Holcim burns a variety of hazardous materials as fuel in the place of fossil fuels. That includes waste solvents, oils, out-of-specification intermediates and products from various industries such as the paint, plastics and petroleum industries.

The public hearing is scheduled for 27 January 2015. The notice was released by the US Environmental Protection Agency and the S.C. Department of Health and Environmental Control. The plant is currently allowed to burn waste-derived fuel in its cement kiln. The permit will allow the plant to also treat and burn the fuel in the precalciner.

Holcim is also seeking a permit to construct a new stream channel designed to protect the plant from potential flooding. The project is awaiting approval by the US Army Corps of Engineers. DeCarlo said that the company expects to receive approval to proceed though is not certain when it will occur.
